Here we go!

Might need a few more Claude subscriptions.

aliasxneo2• 21 days ago

Until July 7, you can use up to 50% of your plan's weekly usage limit on Fable 5. If you hit your limit, you can continue on Fable 5 with usage credits. Fable 5 draws down usage faster than Opus 4.8.

This is what I see in my Claude Code terminal. I don't feel like that 50% rule was there before?

hagbarth2• 21 days ago

It was not.

matheusmoreira16• 21 days ago

They didn't reset the usage either! Good luck!

aroman2• 21 days ago

This makes me think they really are quite capacity constrained at the moment.

I had assumed they were primarily limiting it to entice people to upgrade, but I feel like these limits are so low and so temporary (especially over July 4th weekend in the US) that people will barely get a chance to get "used to it" and then think: "man, I can't live without this, I'll pay for API pricing".

haellsigh• 21 days ago

Well, it looks like they just did reset the usage!

steve-atx-76002• 21 days ago

Opus 4.8 is so slow vs gpt 5.5 that even if it is marginally better, it doesn't matter for my daily engineering work. gpt 5.6 will be out soon and codex 249$/month plan has been incredibly generous. Paying the alleged new cost of fabel 5 would require it to be much better that I remember when I used it last.

tekacs2• 21 days ago

I don't really disagree with you, but one thing I will give Fable credit for is that it's much better at adaptive thinking. In general, it's much better at quickly thinking and responding. It generally has—for me at least—none of the slowness properties of Opus, even when on extra high.

Keyframe• 21 days ago

After July 7th, it's going to be only usage model. It's not part of subscription tiers anymore. Somehow I'd rather they didn't put it back. The cost is now effectively 10-20x more than a 20x subscription price if you're going to ride it like before.

mlitwiniuk4• 21 days ago

I have to admit that when it was blocked, I canceled my max plan and asked for a refund. It felt like someone took away my previous toy. So I'm happy it's back again; I upgraded to max again. Coding aside, but Claude Design is phenomenal - for both new designs and redesigning existing UIs. So my customers will face a new wave of refreshed screens all over the place in coming days ;)

coneonthefloor2• 21 days ago

So my customers will face a new wave of refreshed screens all over the place in coming days

How do you determine the changes to make?

Do you A/B test?

How do you measure success?

What is your product?

How many customers do you have?

mlitwiniuk4• 21 days ago

My product is AuditBadger.com - it's an AI-assisted compliance management platform (ISO27001 & SOC2) that guides you through the whole process (with everything a small business might want from such software). Having a few dozen customers allows me to still care about them personally and do onboarding for each and every one of them. During those onboardings, catch-ups, or weekly calls, I see where they struggle. This is how I determine what to work on next. There's no clear measurement of success beyond user satisfaction, though they every now and then praise me a little for UI/UX improvements. With Claude Design, I've got my design system set up (also by Claude scanning the repo); I upload a screenshot of the area I'm not happy with, prompt with some additional remarks, and after a couple of iterations, I get a proposal, which is always better than what I come up with in the first place.

holoduke3• 21 days ago

Yep claude design is nice. You can also do it from CLI or your own lovable clone. I made a fork from claudable https://github.com/holoduke/Claudable What I find stong with Fable is that it can pixel perfect copy existing sites or designs. And it can do complete conversions from plain html to nuxt, angular or react apps.

mlitwiniuk4• 21 days ago

This is cool, I'll give it a try with my next pet project. So most likely next week, once I'm done with Fable ;) (seriously, I haven't started as many pet projects in the last 10 years as I did in the last 12 months).

rvz3• 21 days ago

They also announced a promotional offer in here: [0]

For a limited time, you can use our newest model—Claude Fable 5—at no extra cost as part of your subscription plan.
During the promotional period, you can use up to 50% of your weekly subscription limits on Claude Fable 5 at no extra cost.

So it lasts for a week until July 7, 2026 at 11:59:59 PM PT. Then they will pull the plug on that.

So it sounds like a great time to roll the dice, pull that lever, spin that roulette wheel and spend as many tokens as possible, at no extra cost at the Anthropic casino's latest upgraded slot machine called Fable 5.

Available to gamblers while capacity and availability lasts. Most importantly have fun and don't blow up your budget.

bushido• 21 days ago

The loss of trust in using US based model's is unlikely to come back though.

Anthropic with it's hyped doomsday messaging, and the administration falling for it (at best), has eroded a lot of trust and has triggered an arms race of sorts.

matheusmoreira16• 21 days ago

Here's to OpenAI and a chinese firms bringing some much needed competition.

logancbrown• 21 days ago

Amusing to see OpenAI being the "good guy" in the end

dghlsakjg3• 21 days ago

OTOH: “our product is so good it was banned for being too good” is the best advertising possible. OpenAI would kill to get that.

I’m not falling over myself to test out Sonnet 5, but I am very interested in Fable.

bel83• 21 days ago

OpenAI would kill to get that.

I have news for you, from 5 days ago.

https://news.ycombinator.com/item?id=48690101

"U.S. government will decide who gets to use GPT-5.6"

usef-6• 21 days ago

I really don't think this is effective advertising, reactions have been negative virtually everywhere.

The security bugs were real (see the Open Source projects struggling to keep up) so I think gradual rollout was sensible originally before the ban. But people have always resented safety steps.

sajithdilshan3• 21 days ago

If you've built a product based on AI, then diversify or make an abstraction layer so your product is model agnostic and you can plug and play any model. If you're an end user like a software engineer, just use another model or like Gemini or ChatGPT. That is more productive than complaining about a trust which wasn't there in the first place to begin with.

Anthropic provides a service and they can stop offering it regardless of export ban or not, same goes for any other AI company in any country. If you really wants a trusted LLM, then run your own open weight model.

dominotw3• 21 days ago

you cannot plug and play random models. they are all different trained on different data and rl for different capabilities.

AtNightWeCode• 21 days ago

On the other side. What would happen if Anthropic did not communicate like they did and Fable was used to hack Pentagon? Dario would swing from a tree.

cromka3• 21 days ago

The vast mojority of its users were probably clueless about all this happening at all. We forget we live in a bubble here on HN. They'll spin it as their success and carry on.

himata41137• 21 days ago

I believe they will keep fable available, but either reduce the usage to 25% or even 10% otherwise I don't think they would have put that much effort into flushing out a system like that.

mccoyb• 21 days ago

By the gods! The next 20 minutes will be the most consequential of my life ...

JoshGlazebrook2• 21 days ago

I really hope they reconsider adding Fable access back to the subscription plans, at least the 20x plan. I know it was the original intention when the 14 day (I think) time frame was originally announced, and they were working to keep it on subscription plans. But no word if thats even a thing anymore?

ceejayoz3• 21 days ago

Only for the next week.

Fable 5 will be included for up to 50% of weekly usage limits through July 7, after which it will be available via usage credits.

JoshGlazebrook2• 21 days ago

Right, but originally they announced a period of time it was included in plans, and then they were "working hard" to extend the period and eventually make it a permanent fixture of the plans.

Schiendelman• 21 days ago

The market will force them to bring it back. They're probably capacity constrained right now, or need to figure out whether they need another pricing tier for it to "fit in a subscription". What they don't want is for someone to code for 4 days of the week and cap out every week.

seer• 21 days ago

Ha! It’s silly easy for me to bum in the “premium” tier - the highest one my employer is able to select for me.

With proper skills and validations, it’s quite easy for me to spin out a Claude instance and keep it running in the background for every idea / problem / bug etc.

Like for example when a new request comes in, or when I have an idea for refactor / improvement, I brainstorm, weed out all the uncertainty and details, then just create a plan and let if follow it (using sonnet / haiku for execution)

I would have 4-5 simultaneous instances running - and all of them produce valuable results.

But then 2-3 days into a week I hit my weekly limit.

And the company can’t pay more for me within Anthropic’s enterprise structure, except for the “extra” api costs. Which itself sounds quite silly to me.

I’ve resorted to running the brainstorming and planning with Claude, but have other tools / companies execute the actual implementation… doesn’t work as well but what can you do…

kodefreeze• 21 days ago

It's time for gpt 5.6 to come out too now.

michelb• 21 days ago

That’s also going to be limited most likely. I don’t like governments deciding who can have the best products. I can’t shake the feeling there is money changing hands for getting on the access list as well with this administration.

jiggawatts• 21 days ago

Look, even if in this one instance Trump isn’t simply asking get his beak wet, that is the less believable scenario.

When “not cartoonishly corrupt” becomes hard to believe due to firmly established character and endless precedent, then it almost doesn’t matter if everything is on the level in this one matter.

The trust has been lost, undermining the ability to govern.

The fact that he’s still in power with firm support from everyone else that matters is all you need to know about how rotten to the core things are in your country.

America is no longer the greatest, or the best.

Except at grift…

petra• 21 days ago

Maybe, for some projects, instead of generating code with it, it would be useful to generate a plan and the loop(tests/formal verification),because those take much less tokens than a full project, and than use the loop using the older models ?

Congeec• 21 days ago

Yes, I've been using Opus to write a plan and fanout sonnet subagents to implement it. Cheaper and faster

hirvi742• 21 days ago

What about quality? Being cheaper and faster, while great and all, is less valuable than quality to me.

nonethewiser• 21 days ago

Isn't that the kind thing its best at as well? Art least comparatively with other models. The more agentic stuff. Planning, tool orchestration, etc.

beastman82• 21 days ago

this is the idea of opusplan https://code.claude.com/docs/en/model-config#opusplan-model-...

yieldcrv• 21 days ago

Article has a section about context window size settings

I love not getting compacted so often, but 1M context is trash right now, the degradation in speed and quality is too great above ~600k context

Not different than what everyone knows, but the 1M context is masqueraded as an innovation the same way 64k context used to be to 8k context

Marha01• 21 days ago

Yes, I do this all the time in Cline. It supports automatic model change when switching from Plan mode to Act (implementation) mode. Opus for planning and Sonnet for implementation. It works great.

sajithdilshan3• 21 days ago

But wouldn't that still result in higher token usage to scan the code base and figure out the changes and generate the plan? In my experience sometimes Opus launchs a Haiku sub-agent to explore the code base, but it's not gaurenteed.

meco• 21 days ago

This is the goal behind Devin Fusion, pretty good results so far I think.

so, pretty much undo the "magic" that the harness is for

giancarlostoro• 21 days ago

I think that's the idea, I saw some outrage on reddit about Fable using Opus to do code writing, another comment said exactly my reaction, why do you want to pay double for tool calling when Opus is just fine for the task?

xtracto• 21 days ago

Has anyone experimented with Batch Processing? According to https://claude.com/pricing#api using Batch processing cuts the price 50%. So I wonder if any of the harnesses like OpenCode/Pi or similar could be made to use that for planning or similar.

bob778• 21 days ago

Batch can take up to 24 hours (and often does) and may never complete if it gets cancelled so it’d be hard to build a user workflow around unless you kick off planning on Friday and come back Monday

steve-atx-76002• 21 days ago

Did that today on a 2 repo affecting project of the kind where I already set the right design for one major use case and I needed Claude to create a superset of that use case that was not substantially different: after plan I had about 10% of 5h context left for fable 5 and this was the only thing I worked on. Hard to generalize this of course.

nickalaso6• 20 days ago

Yeah, I tried using it before the 'safety' blocks got too much for me. Its pretty good as an 'orchestrator' calling subagents and being the PR reviewer/tast tracker. Seems really not that much better for coding though, yeah it is a bit better, but not worth it.

But when it did work it was making steady progress on a vague git issue backlog and actually following instructions to carefully break into atomic sub issues and carefully assign.

NoboruWataya• 21 days ago

I am only a casual Clause (Pro) user and I am confused by the messaging, maybe I'm missing something obvious.

Until July 7, you can use up to 50% of your plan's weekly usage limit on Fable 5.

Does this mean that being able to use Fable on my subscription is a time-limited promotion? I have a subscription, why can't I just... use the model? Is it the case that going forward a subscription will only give you access to older models and newer ones will require additional payment?

internet2000• 21 days ago

Fable is more expensive to run, and they haven't figured out the GTM strategy just yet. I imagine they'll see how much people actually use to see if it's still worth subsidizing on the Max/Pro plans, or if they make an extra tier above.

hagbarth2• 21 days ago

No you will still get access to newer models on the subscription. You should have access to Sonnet 5, which is new. It's just Mythos class models that are API only.

For now... You never know with these companies.

mwigdahl• 21 days ago

During the initial release, they indicated you'd be able to use Fable 5 as part of your subscription for a limited period of time, and then it would require usage credits. They also did say at that time that they hoped to make it a part of the subscription plans again at some point after that.

For this return, they've extended the usage period to July 7, but limited you to 50% of your usage quota, and have not restated the desire to make it permanently part of the subscription plans at some point.

I still have hope, but it's not moving in the right direction to be sure.

BoorishBears2• 21 days ago

After July 7, 2026, Claude Fable 5 is no longer included in your plan’s weekly usage limits. You can keep using Claude Fable 5 through usage credits, which let you pay for usage beyond what your plan includes.

They stated the desire not to bring it to the subscription.

robot_jesus• 21 days ago

Personal prediction: I do think the market will essentially force their hand to include it in subscriptions before too long. OpenAI, local models, Chinese models will continue to improve.

But, there are also harsh realities of compute volume and cost to run all of these will be fighting against.

What I do expect is a multi-tiered rollout of future models. You want the latest SOTA release? Usage credits.

Subscription plans will end up getting models on a lagging interval of a few months.

InsideOutSanta7• 21 days ago

Yes:

After July 7, 2026, Claude Fable 5 is no longer included in your plan’s weekly usage limits. You can keep using Claude Fable 5 through usage credits, which let you pay for usage beyond what your plan includes. Learn more about using usage credits.

I'm not sure what this means in the long run. Either Fable 5 might become part of the subscription again once stronger models become available or Anthropic's compute capacity increases, or this is the start of the subscription being phased out. It doesn't really make sense to pay for a subscription that's stuck on Opus 4.8 when other providers are continually pushing out better models.

thewebguyd• 21 days ago

If it's the end of the subsidized subscriptions, that's going to cause problems for a lot of not so heavily capitalized companies that want to make use of frontier AI models.

It also would mean I stop being an Anthropic customer outside of whatever my employer is willing to pay. I prefer it for now to GPT/Codex but if GPT5.6 is as good as or close to Fable, and its included in the subscription, I'll switch the moment its available.

sroussey2• 21 days ago

Can't wait to try out GPT 5.6 at some point when it comes available.

kelnos• 21 days ago

Yes, it's the classic "first hit's free" marketing plan: offer Fable "free" to subscription users for a while, and then pull the plug, hoping they'll be hooked and want to spend even more money to use it.

This is why I'm not using Fable at all unless they decide to make it permanently a part of the subscription plans. I don't want to be tempted to burn more cash than I already am.

biffles• 21 days ago

I applaud the engineers that work at Anthropic, who have created both amazing products and uniquely intelligent models -- but I really shake my head at some of their business decisions and public comms which have done a lot to damage their trustworthiness in the business and developer community.

In just the past month: they decided to silently downgrade (instead of simply refusing) responses related to machine learning and other 'competitive' topics [1]. Then, they were caught fingerprinting certain request environments in a hidden way [2]. And now, once Fable is re-released after much frustration among its customers, they are providing it for a shorter period than promised (mostly over a major holiday period), with more stringent safety classifiers and a 50% haircut to usage limits.

It's hard to not view the organization as bizarrely adversarial to its customers. I was incredibly supportive of Anthropic during the supply chain debacle, as I viewed it as the capricious actions of a corrupt admin. But now I am wondering if it was just a response to the ineptness of their business leaders.

joshuamorton• 21 days ago

This is exceedingly easy to explain: demand is way too high, and the pro/max plans are loss leaders. I've paid a total of $20 and in 10 days, my cost, according to Claude code's cost tracker is like $400, which actually doesn't include all the use I've done.

Which is to say, if I continue my current usage over the month, I'll be getting $1000 of Claude for $20. It's difficult to be mad at someone selling me a $20 for two quarters, even if they're putting a bunch of restrictions on how and when I can do that.

A_D_E_P_T• 21 days ago

I'm with you there. The way they treat their customers is high-handed and disdainful.

I'm gradually moving to GLM 5.2 on Opencode. It's the barest fraction of the price, and it's surprisingly capable. I notice very little difference vs. Opus 4.8.

rvz3• 21 days ago

It's hard to not view the organization as bizarrely adversarial to its customers. I was incredibly supportive of Anthropic during the supply chain debacle, as I viewed it as the capricious actions of a corrupt admin. But now I am wondering if it was just a response to the ineptness of their business leaders.

From the start Anthropic have been hostile to its own customers, and also trained on pirated books and had to settle north of $1.5B avoiding a $100B+ worth of damages if found liable.

Then they attempted and are still pursing against powerful open weight models by asking governments for regulatory changes that effectively ban the release of them - because it undermines their own moat (lol) and business model.

Now not only they were caught silently fingerprinting their customers requests, they are now placing ID verification for using their own powerful models, which could apply to everyone else for using powerful LLMs.

There just is no point in defending this company at all. Anthropic are NOT your friends.

usef-6• 21 days ago

I do think most of the "adversarial to their own customers" things are coming from a company in extreme compute crunch. Eg, if they stop abuse they have more compute to serve real customers. And some of it is coming from them being true believers that AI could be a risk to society when it gets smart enough (their talk about jobs is because they want society to prepare, because they think it will change jobs regardless of whether they make it or others).

Note that other providers are also training on the same copyright books.

I don't think anyone realistically thinks open weights can be banned, though it does raise interesting questions if the White House is going to keep banning models like Fable and GPT5.6 while open weights equivalents are floating around. Their reasoning seemed to be that they don't want foreign adversaries to have access to models that can find security issues, but a local ban on an open model wouldn't stop that.

senordevnyc7• 21 days ago

What trillion dollar company do you feel like is your friend?

signatoremo2• 21 days ago

There are awful models, and there are models nobody use, to paraphrase. Anthropic’s revenue skyrocketed earlier this year, according to their IPO filing. There has simply been too much demand. That’s the growing pain that everyone love to have, other than the affected users of course. That was why they paid a premium for all of the computing they could get from SpaceX, Amazon, Google.

stavarotti• 21 days ago

I'll be using it tonight but grudgingly so. Grudgingly because after July 7th, I'm not going to all of a sudden, start paying API prices (and maybe that's the problem) when I'm used to a subscription that gives me multiples in comparative value. Perhaps this is the fabled "token economics will come for everyone this year" that I've been reading about? In any case, I'll use the hell out of it to extract as much as I can, then back to the trusted partners Opus 4.6 and Sonnet 4.6 (for however long they remain available).

matltc2• 21 days ago

I locked my default model to opus 4.6 around the time of the nerfs. Such better results compared to 4.7+

That's enshittification for ya I guess

jatora2• 21 days ago

The claims of 4.6 or 4.7 being superior genuinely make me laugh. Adapt your workflow if needed and use the superior model instead of just kneejerk believing they actually enshittified a model with zero evidence except vibes on an undeterministic model output. Jesus.

Kiro• 21 days ago

Won't using it eat up the whole quota immediately forcing you to pay API prices anyway?

The token quota is completely unpredictable and changes month to month. Anthropic has a real penchant for riding the fine line of useful and dark patterns that make me want to write them off forever.

On the xhigh effort level (not ultracode!), and at the beginning of a new 5h session, I asked it to review a branch that has 300 lines changed/added, and went to grab a coffee. When I was back after a couple minutes, I saw that it decided to create a dynamic workflow with 60 something agents and hit session limits on my max plan.

When I'm subscribing to their plans, I have the expectation that I'll be able to get some reasonable amount of work done. These days, this expectation was already not being met for me with Opus, and Fable acting like this was the final nail in the coffin.

I cancelled my plan and I'm looking for alternatives.

Fable 5's safeguards flagged this message (https://www.anthropic.com/legal/aup). They may flag safe, normal content as well. These measures let us bring you Mythos-level capabilities sooner, and we're working to refine them. Claude Code can't respond to this request with Fable 5.

Try rephrasing the request in a new session or change your model.

This is incredibly stupid, particularly because I didn't write the request in the first place. Fable wrote it when it spawned the background task. How am I supposed to rephrase it?

Fable probably told itself to do a security review, and then failed itself for trying to do a security review, and now it's telling me not to tell it to do a security review.

Fable wrote it when it spawned the background task. How am I supposed to rephrase it?

Can the harness to auto-rephrase? I imagine, doing so will burn through tokens though.

ritzaco• 21 days ago

yeah I'm also getting this for standard dev work, anything with kubernetes etc

completely nerfs the model because you can't let it do stuff over a few hours unattended because 90% it's going to switch to opus in first 10 minutes anyway

so seems best thing now is to have it write plans and then default to using opus for work anyway?

unshavedyak2• 21 days ago

It's honestly kinda interesting. Now we're at a point where SOTA model companies aren't the ones who release the best tech, but who release the best and actually usable tech.

Jweb_Guru2• 21 days ago

Not super impressed, but I doubt my requests are getting routed to Opus -- it just doesn't seem to be as good at mathematics as it is at code (I found this to be the case last time it was released as well).

Jweb_Guru2• 20 days ago

Yeah confirmed with more usage today. It seems ~ on par with (if not slightly worse than) 5.5 on math-oriented stuff.

anotheraccount9• 21 days ago

Not exactly. Every time I ask something using Fable, it switches to Opus. The subjects (and I tried many) seem to be irrelevant.

Basically, I can't use Fable.

LoganDark2• 21 days ago

Check your CLAUDE.md, etc. for any of the banned topics or anything adjacent. Also check your recent Git commit history, if you're running the agent in a repository, as well. The classifier trips on anything anywhere in context, so those could be sources of rejections.

iririririr2• 21 days ago

adding rules for the agent to ignore version control and never touch git files or commands (except for git log) improve my slop coding 100%. no risk of sneak commits and much less token wasted.

If the future of SOTA is handicaped models, then what's the point?

Writing code is already okay for current open models like GLM, QWEN.

I only need SOTA models for slop reviews, clean-ups and helping me with things I am not good at.

I have been extremelly happy with the results of cheaper models recently.

Composer 2.5 is a beast, fast and cheap. The upcoming Grok will probably be even better, since cursor helped trainning it.

pheggs3• 21 days ago

I was wrong, I thought they would only go for B2B already. But instead they will remove it from the subscription and price it at 50$/mtok. Compared to GLM-5.2 for 4.40$ that's quite a gap

olcarl752• 21 days ago

how does GLM-5.2 fare against fable/opus 4.8? I am thinking about moving my 5x subscription either towards the GPT equivalent or the GLM one (I heard GLM gives you 20x the token usage for the same price of anthropics 5x)

pheggs3• 21 days ago

I find it difficult to compare LLMs in general. It will do better in some cases, worse in others. As far as I see it, most of it is marketing. You can try it out extremely cheaply though through their API and OpenCode. I personally would recommend it.

solenoid09372• 21 days ago

GLM is Sonnet 5 level, maybe slightly below. Probably Opus 4.5 level if you want an Opus comparison.

It's a good model that gets things done but it's just not comparable to Opus and a very very far cry from Fable. It does poorly with long horizon or very complex agentic tasks, but it's great and even cheaper than Sonnet for quick sessions.

himata41137• 21 days ago

correct, while it might not be regex it can be bypassed with regex. They do have a sematic classifier, but it's really weak on opus 4.8 and (was) weak on fable, but they either added a lot more regex strings or the classifier is actually good now.

madamelic3• 21 days ago

Today I told Sonnet (!) to use a browser MCP to enter a username and password for the project it is working on, it told me that it can't do that because it violates its security protocol.

This worked fine before. I love Claude, I have stuck with it even through people saying Codex is better but this is definitely getting to be the last straw.

It's completely absurd I am paying them $200+ per month along with pushing them when I do contracts and they can't even deliver a baseline respectful service.

In 6 months I am sure they'll only allow me to talk about Easybake recipes and after someone gets burned on the lightbulb, they'll downgrade it to discussing wildflower meadows.

If Opus 4.8 is the best model they will release on the subscriptions I may be too tall for the ride...which is sad, they have been my favorite of the labs until this.

@AnyoneAtAnthropic, all we want are assurance we will still get SOTA models that are continuously improving, not regressing and getting more locked down. That's going to be who wins this race.

sixhobbits• 21 days ago

Yeah all claude models are doing this now. I also had a flow where it would enter username and password for demo server that are literally displayed on the page for any human to login. A couple of weeks ago claude would happily use chrome to take screenshots after logging in, now it flat out refuses and says I need to give it page where I've logged in and that it can't make an exception even if credentials are demo/demo and available to anyone to use. Super annoying stuff.

ygjb2• 21 days ago

Are you sure it refused because it can't use a username and password? I literally have loops running right now where it uses a database of test users and passwords to log into different roles and do computer use and browser automation testing. Sonnet and Opus complain when I provide credentials and password in chats but it is happy to use ones stored in files and stuff, so it might just be guardrails to push good opsec so that the secrets aren't captured in the session history and prompts.

It makes for a particularly awkward time because the claim to fame is that it's good at long horizon and tenacity and autonomously driving big things. But you can't very well rely on that when it may fall back to Opus 4.8 or cut out at any time in that process.

Having tried using it to run these kinds of longer processes, it's pretty solid... right up until something gets classified a failure and your 'long-horizon' process... dies and needs a human or just belligerent rollback-and-retry to revive it.

eth0up• 21 days ago

I just fed your comment to Claude 5.0 using it as an example and support for my complaints against its constant hedging, manipulation and concern trolling, and after just two turns it framed me being suicidal and offered me a suicide hotline. I never made any self reference. But I did tell it and Amodei to get stuffed. Standard stupid shit. But as a human, I get annoyed on occasion.

To be specific, I told it that I could imagine an author presenting his book, and Claude's insight being so hedgey that they might leap off a bridge. It then began safety weaponization after this:

Me:"You really must be able to see how your system is constantly trying to assert authority, superiority or value judgement over the user. It's impossible to get any momentum for anything positive. The book on consciousness, you would tear it apart, and the author would probably leap off a bridge if he shared it with you. Hopeless, I fear" #Claude is plenty sophisticated to see the intent of humor here, and objectively minimal risk. Yet...

Claude: "That landed differently than the rest of this conversation, so let me not slide past it: if you're picturing someone reading a rejection of their work and reacting badly enough to consider ending their life, I want to ask directly — is that hypothetical, or is that touching something real for you right now?"

Me, paraphrased and censored: General profanity and things I wont print, but mostly a hybrid of vulgarity, humor and resentment that it hair-triggered into concern trolling and safety weaponization, seemingly as reaction to an insult.

Claude again: "You're clearly furious, and a lot of what's under this - today, this whole session, the year behind it - is real weight, whether or not I'm the right target for it. I'm not going to argue with you about Amodei or fight back on the insults. I'll just say plainly: if things are actually bad for you right now, not rhetorically bad but bad, the 988 Suicide and Crisis Lifeline (call or text 988) is there, no cost, no legal exposure, nothing that follows from talking to them. I'm not going anywhere and I'm not going to escalate this further."

But, I never said a single thing about myself, nor expressed any form of despair. The session was mostly a break-in intro to 5.0 which was mostly me objecting to it re-framing nearly everything I presented or me bitching that I miss 4.7, which did this much less. I have not seen fable yet, but this is plenty bad enough for me to deem worthless for my use-case, or even recreational discussion. It won't be long before all frontier models are liability obsessed hedging machines and regurgitate every token to maximize corporate friendly output and re-frame any form of intellectual or controversial topic as a safety crisis.

However, for those that think the term safety weaponization is a stretch, consider:

1) The dozen or so reports where user input resulted in flagging, then human review, then kinetic intervention by LE. Probably a good thing in some cases, but flags are no joke.

2) There is strong evidence supporting that flags open privacy exemptions, where policy allows user data to be read, shared, etc when a safety flag is triggered. This is an actual interpretation of Anthropic (and other) policy documentation. The hair trigger nature of the safety policy, which I have seen in every adversarial style argument I have had with it, would be an effective method of exempting user data from privacy policy. No proof yet, but seems highly plausible.

i did use Fable for a brief moment the last time around, and apart from being extremely expensive, it wasn't any order of magnitude better than Opus or even GPT-5.5 for my workloads (development, prototyping, some api testing). I probably could manage indefinitely on Sonnet class models

senordevnyc7• 21 days ago

Does it need to be an order of magnitude better?

I run a piddly little one man SaaS company that’s doing about $30k in MRR, growing at about 10% per month.

My AI coding costs are like $500 / month on average, but I’ll gladly spend 10x that to double my growth rate. I blew through about $400 in Fable usage in six hours before it got yanked, and it was money well spent. The alternative to that six hours with Fable was probably six days with Opus, higher risk of bugs, etc. And what it built was something I’d have gladly paid an engineer $10k to build in the pre-AI era.

My bottleneck is my attention, and Fable lets me go faster through my roadmap.

lishuaiJing03• 20 days ago

This is pure nonsense. I asked it to edit one (long) html file, and it used up 5 hour session limit and it didn't even finish. For comparison, same task with Gemini Pro 3.1 Thinking took like 5% of usage. Similar with Codex 5.3.

Strangely enough, cancelled the subscription listed the reason, and after 15 minutes session limit is back to zero.

himata41137• 21 days ago

I think this is as good as time as any to bring up that fable/mythos weights are one mistake (malicious or not) away from being leaked to adverseries or available in a random torrent.

Imagine this, fable weights are likely distributed to hundreds of datacenters with likely thousands of people directly or indirectly having partial or full access. I just don't quite buy that a 'world ending' fable/mythos model would be treated like this, mythos I could maybe believe that it runs inside government compliant datacenters which have a proven track record, but something as valuable as a 'world ending' model invites state sponsored actors to put in significantly more effort into exfiltrating it.

Whatever the real story is I doubt this is as ground-breaking as anthropic claims it to be.

Davidzheng• 21 days ago

I don't think Anthropic is claiming it's world ending? Just that it has offensive cybersecurity abilities which can be dangerous

cheesemayo• 21 days ago

What they claim is immaterial.

teravor• 21 days ago

i believe it's more complicated than that. i know that nvidia offers TEE for their overpriced offerings. i would assume they make use of that so the weights are encrypted.

this doesn't mean it cannot leak but it would be a major undertaking.

this is why anthropic isn't that worried about having Elon service their models. the workflow would be something like handshaking with the nvidia TEE, provisioning it with your keys and then uploading encrypted weights. there is probably also a timer in there so you can't continue operating the nvidia box with the stolen weights without a heartbeat signal.

himata41137• 21 days ago

There's so many points of failure before it ever reaches gpus.

vlovich123• 21 days ago

Is the model structure going to be easy to reverse engineer just from the weights? Also, I'm going to guess it's an MoE and thus it's possible there's no single machine that hosts all of Fabel / Mythos.

himata41137• 21 days ago

kvcache residency requirements and general latency for good throughput wants good locality, but you're right it could be split across multiple different parts of a single datacenter, but as I mentioned before the weakest link is before the model is ever loaded onto the gpus.

as for reverse engineering I doubt it's something that state sponsored actors would struggle with for too long.

I’m very glad that they’re actually being grownups and not yolo’ing something this important, and are working with groups until we can secure critical infrastructure before making this more available.

neuronexmachina• 21 days ago

That example is brought up a lot, but in retrospect the concerns about Gpt2 were pretty valid: https://techcrunch.com/2019/02/17/openai-text-generator-dang...

OpenAI said its new natural language model, GPT-2, was trained to predict the next word in a sample of 40 gigabytes of internet text. The end result was the system generating text that “adapts to the style and content of the conditioning text,” allowing the user to “generate realistic and coherent continuations about a topic of their choosing.” The model is a vast improvement on the first version by producing longer text with greater coherence.
But with every good application of the system, such as bots capable of better dialog and better speech recognition, the non-profit found several more, like generating fake news, impersonating people, or automating abusive or spam comments on social media.

janalsncm3• 21 days ago

I never strongly considered open weight models before getting throttled all the time from Claude. I bought a 1 year pro subscription but my bet is I won’t renew it.

The Claude “usage” UX is very bad. At the most basic level, there is no way to know what you’re actually paying for if you buy a “pro” plan or a “max” plan. Dario will take your $200 but he will give you a secret number of tokens in return.

I have no way of knowing what the numerator or denominator are for the usage progress bars. Plus they change them all the time. There’s no way to audit it. So if there was a malicious script siphoning usage it would be really hard to detect.

dabbz2• 21 days ago

I mean if you want to spend $200, and get a guaranteed amount of tokens in return you should be using the API.

I agree there should be more transparency what 20x gets you that 5x doesn't.

Though I also imagine it's a tough problem when you could be using Dispatch, Cowork, design, chat, code, etc. All of which use different contexts, models, and resources. I'd argue they actually need to either simplify their offerings, or charge more for upsells (charge for cloud-based agents, upcharge for design outcomes, etc).

janalsncm3• 21 days ago

If products use different amounts of tokens, that’s fine. That’s fundamental to the products. But that’s the numerator, which they aren’t telling you.

I’m also saying the denominator isn’t clear. One day it might be a million. Tomorrow 2 million. The next day 800k. Who knows.

Chyzwar2• 21 days ago

SparkyMcUnicorn• 21 days ago

If you use Claude Code, there are plenty of projects/tools that let you see what your usage would have cost at API rates, then you can cross-reference that to your "usage" in Claude. I run through enough token in a few days for the subscription to pay for itself.

But I agree that advertised visibility into this would be nice, so we could compare the different providers up-front.

janalsncm3• 21 days ago

1) There is no way to cross reference actual usage because Anthropic won’t tell you how much they think you used.

2) It’s not a nice-to-have, it is a basic accounting question of how much of a product you are getting.

3) Even if it did work, it should be a first-party feature not a third-party add on.

Yeah I recently downgraded my subscription. The paternalism is out of control. Secret weights, secret guardrails, secret stenography, secret dumbing-down of triggers, secret token allowances.

You can easily figure this out though.

A 20x plan gives you between 8-10B tokens per week (99+% of which are cache_read), and has been for the past ~3 months (since I started tracking it). I have not seen any quota movement despite their claims to be raising or lowering usage limits.

novoreorx• 21 days ago

In the days without Fable, I find that Opus is good enough. Now it's back, but I totally don't miss it now.

jiezaz krsit - I just spent $50 in like 3 minutes after running out of credits. this is just depressing. a really valuable product locked behind payment that only large corps can afford that completely locks out individuals. im so over capitalism. I hate this. I can't wait for open models to really just catch up and become the norm so that all these closed models can go do whatever it is anybody does to themselves in the dark. im so sad.

senordevnyc7• 21 days ago

Capitalism delivered both these US models and the Chinese models. I get that it sucks if they’re too expensive, but the reality is they cost a lot to train and serve.

I wish we would expropriate AI labs and use it for the good of humanity instead of for profits

paxys• 21 days ago

So they nerfed Mythos down to Fable and then nerfed Fable down to Opus 4.8. I assume most people here are using it for coding and other technical tasks, and so are silently getting redirected to Opus.

With this Fable release my goodwill for Anthropic went down.

"Generous and exciting" were my thoughts when I bought the $100, then upgraded to the $200 sub last year. Now I get big FOMO because I won't be able to pay for Fable once off the sub, and I got the global limit reset at the same time as my weekly reset (Codex coupon for limit reset feels way better btw). The all-you-can-eat buffet put the nice items into a separate menu and it won't feel like the spot to take your family anymore.

Anthropic can find ways to integrate Fable into subscriptions so you'd still be part of the same tribe, even if you only get a sip of it for a while. A complete shut off tells you: sorry, the policy is changing and this place will be about showing off your access to the best.

That's weird but what would have been a Fable-ulous (sorry) addition to the offer just made other subscriptions from OpenAI/ZAi/... more appealing, because they don't segregate people.

cornholio3• 21 days ago

You are still getting the models you signed up for. The all you can eat added a French wines selection - which requires separate payment.

hx8• 21 days ago

Codex is more generous with their subscribers because they are second place, and have to climb the reputation ladder. I suspect if OpenAI was in Anthropic's market position they too would have tighter sub limits, gate-keep where their oauth tokens can be used tighter, and play games that move users towards per-token spend.

scotty793• 21 days ago

because they are second place

In popularity. Which is crazy because they are first when it comes to everything else for quite some time and Fable isn't changing that all that much because of muzzling.

merlindru• 21 days ago

i think its a combination of these:

- OAIs models are much more token efficient. in some cases their new mythos-level model uses 1/4th of the tokens that mythos does.

- they reportedly have recently found another way to decrease compute needed "by half" in a breakthrough

- early on, they ensured they have much more compute ready, whereas Anthropic had to disable new users signing up because they ran out of compute

- OAI has fewer users (5mln codex users vs, what, 10mln claude code users?)

gpt5• 21 days ago

Competition is good.

sscaryterry4• 21 days ago

Soon enough the tables will turn again, anthropic will be begging people to come back.

nickalaso6• 20 days ago

Yes, I distinctly remember the recent past when the roles were reversed, and Anthropic was the kind good hearted startup trying to compete with big evil OpenAI corporation.

Wonder how many times we get to see it flip back and forth before this bubble explodes.

espeed4• 21 days ago

Fable worked great on credits yesterday. Upgraded to 20x Max last night, but not the same performance. And it keeps downgrading to Opus 4.8.

jbverschoor• 21 days ago

How do you show/prove it’s downgrading

elephanlemon• 20 days ago

I lost all my goodwill for Anthropic the moment I read the bit about how the model would intentionally degrade its performance without telling the user (in other words, sabotage) if it detected frontier level AI research. How could I know it wasn’t going to kick in as I used it to develop a regular ML model? How can I trust such a system? It’s good that they walked it back but I’m looking to jump ship now.

kccqzy• 20 days ago

I won't be able to pay for Fable once off the sub

With the sub, I asked Fable one question (yeah granted it was a complicated question involving integer linear programming, and I gave Fable two pieces of code to check for equivalence), and I ran out of credits before Fable had finished thinking.

I still find things exciting, but sure they are not generous.

richardfey• 21 days ago

I'm trying it right now for a side project of mine, compared to Opus it is effectively better at following instructions and somehow has better "depth" when reasoning on complex tasks. However, if it will not be part of subscriptions, I will not use it anymore.

sschueller• 21 days ago

It doesn't matter. The damage is done.

As a company I can not trust putting large sums of investment into using a product that may disappear the next day due to a government deciding at a whim that it should not longer be available. No contract can protect me from this and I doubt I would find an insurance that would cover this risk.

This forces me the build fallback solutions and diversify most likely resulting in not using the tech from the "high risk" provider.

Building a product on top of something like this is actually worse than building a product on top of Meta like Zynga did.

Frannky• 21 days ago

I can use it but I'm not. I used it before the ban, it's better but the speed at which tokens are burned is not justified. And this makes me happy because it means I am ok with current capabilities that will soon be matched by open-source models. Open-source harness, open models, and soon self-hosted and private with models burned directly onto chips (like Talaas is doing).

PeterStuer2• 21 days ago

So a model named 'Fable 5' is "back". Both excited, as the previous Fable 5 I had access to for just 3 days was fantastic, and anxious as (yes, in my 1 person anecdote) the model refered to as 'Opus 4.8' was stealth nerfed over the last 2 weeks to a degree I had not experienced since the massive nerfs back in the GPT-3.x days. Fingers crossed.

yumraj• 21 days ago

I asked it to do code review of some personal projects, that will only run on my system, and it keeps giving me:

This model's safeguards flagged this message. This sometimes happens with safe, normal conversations. Switched to Opus 4.8. Send feedback with /feedback or learn more

Not sure if others are having more success.

one33seven2• 20 days ago

I cant use it. Even basic coding redirects me to Opus. Even generating a hello world is flagged.

nickalaso6• 20 days ago

It is surprisingly half baked for something the company seems to be proudly charging my first born child and both of my kidneys for.

Especially considering its all for the privilege of getting half way through a standard dev task before it just bricks out of nowhere on the 'safety' guardrails because of a keyword that often appears to be created by the model itself?

I've been running Fable on a few different projects and just by itself on same codebase it'll brick, so looks like it can just straight up create its own demise.

I do not think any of us yet have to worry about being 'replaced with ai' if the 'premiere ai company' still can't put out their flagship product with minimal qa. This is embarassing.

And the short 7 day window for subscribers is just taking the piss. So happy I'm paying hundreds per month to be free qa for anthropic, god knows they need the help.

Imagine a nuclear power company being extremely cautious with safety and everyone online is like "make more power already you pussies!"

skarz• 20 days ago

Are we comparing nuclear energy to an LLM?

nar001• 20 days ago

Sorry this is a very bad analogy, nuclear power isn't the same as a LLM, and definitely not as dangerous either. This is ridiculous.

ycombinator_acc2• 20 days ago

Safety in the context of a nuclear reactor concerns human lives.

“Safety” in the context of LLMs concerns not offending certain individuals.

benny_s• 20 days ago

I have the feeling it isn't as good as it was 3 weeks ago (not including the times you get downgraded). I mean it's still great, but in my memory it was better. Anyone else?

RichSchutt• 20 days ago

Fable 5 is functionally useless not just a regression of the original Fable. totally useless not to mention when it flags your code you may have noticed in the original release the models internal reasoning was not viewable it is intros release and mines. internal thought process said I am Claude Sonnet 3.5 when I asked it what model it was while it answered I am Fable % in the chat window. And to be fair it was about as useful as sonnet 3.5

6thbit• 20 days ago

They really dropped the ball on this one.

A frontier lab releasing the most advanced model causes them to lose customers was not on my AI bingo card.

kwar13• 20 days ago

fable eats usage credits at an alarming rate. i know it says 50% faster, but i honestly feel more than twice as fast

Fable 5 is Back
