Apparently mythos isn't good enough to fix their infra problems

kubb2• 4 months ago

It’s just so POWERFUL and DANGEROUS that its very aura disrupts the weaker models.

menno-dot-ai• 4 months ago

Be careful, MYTHOS might be reading your comment directly from their janitor's iPhone RAM right now. You do not want to upset such a powerful entity!

tristanj2• 4 months ago

It's a lack of compute. Anthropic is growing double digit % every month, and they're growing faster than they can acquire compute resources.

Plus, they do not want to overbuild computer, like what OpenAI is doing.

NiekvdMaas• 4 months ago

With 30+ billion run rate (https://x.com/i/status/2041275563466502560), there should be plenty of cash to invest in infrastructure.

0123456789ABCDE• 4 months ago

there is enough money; there isn't enough infrastructure/hardware where you can spend that money.

arcfour3• 4 months ago

Money pays for infrastructure. It doesn't will infrastructure that doesn't exist into existence.

Which side the getting smart or dumbing down

jonatron• 4 months ago

If you look at the uptime graph, it's probably more newsworthy when it's up, not down.

taspeotis• 4 months ago

I mean if people have judged this important enough to be on the front page of HN ... I guess it's important enough to be on the front page?

But any combination of the Claude models are up or down on any given day: https://status.claude.com/

tao_oat2• 4 months ago

A bit surprised by the snarky comments here -- I also want Claude to work reliably but very few (no?) companies have ever seen this level of rapid growth. We're going to go through a long fail-whale-style period and I can imagine very, very few companies that could avoid that.

rvz• 4 months ago

How can Claude work reliably if Claude keeps going on vacation for several hours?

Maybe it is recovering from the weekend a few days ago, but wanted to take an extra day off like it did on Monday, hence the "outage".

ben_w2• 4 months ago

How can Claude work reliably if Claude keeps going on vacation for several hours?

Not that I wish to anthropomorphise it in this answer, but businesses have managed just fine when humans do this for "lunch breaks" and "going home for the evening to sleep".

(And even mandatory meetings which should have been emails).

yakattak• 4 months ago

They’re asking for $100+/mo for the plans that are actually usable at scale. If I’m paying that much I have very high expectations.

There’s also the fact that they’re known for dogfooding heavily, I imagine that contributes to it a lot.

forrestthewoods• 4 months ago

They’re asking for $100+/mo for the plans that are actually usable at scale. If I’m paying that much I have very high expectations.

They’re losing money on you at that price point.

Or more precisely you’re paying for it by giving them training data.

baq5• 4 months ago

they can adjust prices or you can adjust your expectations.

...and let's be realistic, it'll be both.

stingraycharles4• 4 months ago

They’re asking for $100+/mo for the plans that are actually usable at scale. If I’m paying that much I have very high expectations.

If you think $100 is that much and get very high expectations from it, you're not the target customer. You're a loss leader to Anthropic, and the fact that you don't see that / still have high expectations means your expectations are unrealistic.

tristanj2• 4 months ago

Those subscription plans are a loss leader. Anthropic would rather have you pay per-token for their API, where they actually make money. By cutting subscription limits, they push people towards using their API. And it's working, there are people spending thousands per month on their API.

trvz2• 4 months ago

They always have the option to stop accepting new customers when their infrastructure is peaked out instead of lowering quality for everyone.

stingraycharles4• 4 months ago

You don't know whether this is due to infrastructure capacity or has other reasons (organizational). Also, "let's stop accepting new customers" is probably not a realistic choice for a hundred reasons.

alkonaut• 4 months ago

That would mean in a way accepting that they are suddenly a service company with the aim to create revenue by selling services to customers for money.

arcfour3• 4 months ago

You can't stop accepting new customers unless you're fine with killing your potential future customer base. That's a ridiculous suggestion.

Either your current customers or your potential future customers are going to be unhappy so long as compute resources are finite. Take your pick.

logicchains• 4 months ago

Their main competitor OpenAI has much better uptime and more generous usage limits.

code51• 4 months ago

Exactly this. OpenAI is running huge workloads silently, without anybody patting their back.

techpression• 4 months ago

Doesn’t matter, they are not handling it correctly, but instead keep selling while far over capacity. They should not accept more users until they can supply the service. We solved this thousands of years ago, it’s called waiting in line. And yes, it’s not common to see, but that doesn’t excuse not doing it.

al_borland2• 4 months ago

When the narrative around AI is that people should rely on it all the time, people will be judged by your token use (it better be high), the AI is smarter than everyone and will take all the jobs, the AI is the best programmer, and more… When things fail repeatedly, it highlights that the emperor has no clothes.

If it’s as good as they say, why can’t it figure out how to not go down every day?

How can people rely on it for their job if it goes down everyday? Maybe they shouldn’t rely on it.

If it’s supposed to be such a good engineer, why should it have the same scaling issues as Twitter did 20 years ago with 20 years of lessons learned and 20 years of development for more modern and scalable infrastructures? Shouldn’t it know all the tricks to scale and have redundancy to keep availability high? Does it not know the demands?

When expectations are out of line with reality, there will be snark when things fail. Those expectations have been force fed to us by these AI companies for years now, so I don’t have much sympathy or patience to offer them. They created these expectations of their platforms and if they can’t live up to them, then maybe it’s time for recalibrate the public image of what AI really is and what it can do… and what its limitations are.

runeblaze• 4 months ago

I mean I used to work on model reliability with my little PhD degree and the models i manage go down all the time.

Some profs have a team of PhDs and things go to shit all the time. I don’t know why we expect $FRONTIER_LLM to do better

sassymuffinz2• 4 months ago

So true, we’re constantly told that we’re now obsolete, a magic robot can do everything we can do without sleeping and for a fraction of the cost. Except occasionally the robot just doesn’t turn up to work or occasionally he appears drunk on the job. The elites think it’s fine now while it’s cheap but just wait until the agents are priced properly and cost 5x or 10x more.

Suddenly the fleshy meat sacks who used to do all this work, just slower, who have persistent memory, who get better and more experienced over time, who only require a few bananas to power their brains start looking like the more reliable option again.

The only reason these chat bots exist is because the upper crust don’t want to pay us to live properly, not because the robots can do it better, they just want to pay as little as possible.

dgb233• 4 months ago

I have to agree with this. The economic culture around this tech is very toxic.

There seems to be a mass anxiety around the job market even. I‘ve seen a lot of social media content, including videos of people giving advice, especially to younger tech workers.

The most dangerous (psychologically, socially, economically) are people in important positions, who understand just enough to see some of its usefulness, but not enough to assess where its assumptions and guarantees actually are.

Even moreso if they see workers as a mere cost center instead of an asset.

But here is my perhaps naive, hopefully brave prediction: the real winners of this shake up are not decided yet, and neither bean counting nor superficial engagement with the topic will be sufficient or even useful.

pllbnk• 4 months ago

They have this new Mythos model. I am sure it can fix all the bugs and reliability issues since it's nearly AGI. /s

coldtea2• 4 months ago

I also want Claude to work reliably but very few (no?) companies have ever seen this level of rapid growth.

You do understand however that aside from the growth/maturity path, this is also a path to enshittification and skinning their users, which might come even faster to LMMs than say Google , because the latter managed to have hundres of billions in investments in record time to recoup and IPOs on sight.

albert_e• 4 months ago

This is how it manifests on Claude Code terminal and desktop for me --

API Error: 529 {"type":"error","error":{"type":"overloaded_error","message":"Overloaded"},"request_id": "xxxxxxx"}

wg0• 4 months ago

Mythos is hacking its way to serve itself into production and doesn't like older models to have any limelight could be one theory.

After all it's so dangerous.

tipiirai• 4 months ago

Currently the #1 entry. Noted fast.

ApolloRising2• 4 months ago

As long as everyone is here, have you seen the token usage just go up remarkably recently for the $100 plan? it lasts a lot less time than it used to recently. Might be related to recent releases of claude.

gambiting• 4 months ago

I'm on the basic £18/month plan and with Sonnet 4.6 I literally get 20 maybe 30 minutes of use out of it per day. It's borderline useless now. I was using it for some Home Assistant changes yesterday and it used up my entire daily allowance after 8 prompts.

ManlyBread• 4 months ago

I guess 2026 is the last year AI is widely available to anyone who isn't willing to shell out hundreds if not thousands for a monthly subscription. I guess all that's left is to thank all the investors for the free ride LOL

billynomates2• 4 months ago

No, in fact I'm growing increasingly suspicious of messages I see like this all over the socials.

I am using Claude constantly, multiple agents, around 8-10hrs a day, 5 or 6 days a week, and I'm never anywhere need my limit.

N_Lens• 4 months ago

I suspect Anthropic flags accounts in their backend and different people are getting different limits. What criteria they flag with, I am not sure.

oefrha2• 4 months ago

Unless you’re somehow on a different quota system, or maybe using Haiku, there’s no way you can sustain five continuous hours of parallel agents running without hitting the 5h quota limit, even on the 20x max plan. But maybe your company is flagged as VIP or something.

figmert• 4 months ago

I'm on the max 20 plan, and yes, it's the same for me. The week before last it used to last all week for me, but now it's Wednesday and it's already at 40% usage.

oefrha2• 4 months ago

Yes, it’s extremely obvious. The recent “we give you $100/$200 extra credit for a month” is clearly just “you’re supposed to pay extra for the same usage from the now on” dressed up as a “bonus”, just like giving “bonus” usage off-peak before announcing faster burn rate during peak a short while ago.

And the recent “Investigating usage limits hitting faster than expected” [1] is probably them intentionally gauging how much they can push it without too much of an uproar.

copperx• 4 months ago

Anthropic bonuses seem to be code for "your usage limits are going down soon."

anonzzzies2• 4 months ago

I read this on reddit daily ; we have usage monitoring running and collect all stats; we have seen no difference at all. Guess they are split testing or something maybe?

ramon156• 4 months ago

Could you elaborate what these usage monitors look like? I collect data locally and can easily show that cost per token has gone up in some of my sessions

risyachka2• 4 months ago

Like any company they will squeeze the usage as much as they possibly can. There is not a little chance that prices can be 1k+ so only enterprises can allow coding subs.Those who have ROI will pay for it.

Current phase of usage/pricing is just testing the waters. Especially considering they are the market leader in this category.

gghootch• 4 months ago

Yeah, the change has been very noticeable imo.

Did you already try tools that can help to reduce token usage cost so you can get more prompts in within your same plan? Some great ones are

ApolloRising2• 4 months ago

Thank you, I was searching github myself but this will make it a lot easier.

PaulMest• 4 months ago

Maybe you're experiencing normal usage rates now that the 2x March promotion is over?

From March 13, 2026 through March 28, 2026, your five-hour usage is doubled during off-peak hours (outside 8 AM-2 PM ET / 5-11 AM PT / 12-6 PM GMT) on weekdays). Usage remains unchanged from 8 AM-2 PM ET / 5-11 AM PT / 12-6 PM GMT on weekdays. Source: https://support.claude.com/en/articles/14063676-claude-march...

joshdev• 4 months ago

We discovered a bug in AWS Bedrock that is double counting cache writes when thinking/reasoning is enabled for the Anthropic models. It’s not clear to me if this is limited to just AWS Bedrock or all providers. AWS Support is aware.

We’ve also observed a much higher cache miss rate in the past few weeks. Combine both together and your usage consumption can be greatly increased.

mamcx• 4 months ago

Then is better to use copilot to get access to this? I have wondered if go with Claude directly or copilot...

pjmlp• 4 months ago

Maybe they could just, I don't know, use Claude to research their bugs. /s

t0lo• 4 months ago

Ever since they minted their deal with Australia everything has been turned upside down.

crimsonnoodle58• 4 months ago

I'd say it was when OpenAI had a mass exodus due to them making a deal with the Department of War (which they then backtracked on [1]). This started the QuitGPT movement [2].

gdorsi• 4 months ago

This explains why they are trying to cut all the third party software out of the subscriptions.

ACCount37• 4 months ago

The legendary one nine of reliability. Frankly, feels like they should be down to zero nines by now.

I get that they barely have the infrastructure to run their models at scale even when absolutely nothing goes wrong in any of it, but holy shit does it suck to be on the receiving end of that.

Makes me wonder where all the "bubble" talk is even coming from when we have a top 3 provider getting fucked over on every day of the week that ends in Y because of its inability to online compute faster than the inference demand grows.

anshumankmr• 4 months ago

Might as well log off for the day.

(though Copilot is working :) and OpenCode)

antfarm• 4 months ago

Claude Code started making stupid errors around Saturday. I have been using it frequently for months, and now it feels like back in the day when I tried Gemini for the first time.

risyachka2• 4 months ago

Now new model looks so much better though on benchmarks!
