It's vibes mostly. Like, fable is better on frontend while 5.6sol is better at long running tasks with a lot of subtasks, harness did made them mostly interchangeable as well as able to have them both participate in solving a hard issue. Longest to learn is the ui (I'm more of a GUI guy but this is just too good) and all hundreds of features where you want to do something and then discover the harness already supports it out of the box but you never knew it, yet

most advanced, configurable and capable harness of all time, and i use both 200$ subs with it. Has a huge learning curve though so if you're not into that i'd go with whatever you already use the most

that would be really cool because i myself was unable to make a new whatsapp account recently so i would use that

Consensus itself does NOT matter, omp is objectively the best harness for power users yet it has 0 hn posts about it, zero.

You're fully free to use and try anything and without caring about what others think is right

good tech

while true, the people who will read this and then think twice about implementing and applying things are exactly the people who already doing too much thinking

nothing beside the lack of willing is stopping you from removing its internet access before giving it the file system permissions

slop in its purest non ai form

i love seeing things i saw on twitter two years ago at the front page of hn man like what are we doing

This is kind of like saying grass is green to be honest

im crying bro snuck in india

not sure if its fully real, the source is twitter and this weird paywalled website, but if it is, fuck.

So essentially there are 2 models, Mythos and Fable, they have the same weights but Fable is very safety-nerfed, and only ultra authorized companies have access to mythos with full capabilities

Also why do they just keep doxing people left and right?

Scott Alexander as the most memorable, and then the backlash after they post the backrooms movie creator's house on twitter recently

Just very shortsighted behavior

That is actually not that bad of an idea huh

Can't wait to see a video from a half sloppy channel about this on my youtube front page in roughly 4 business days

First ever argument being "People do not realise how much of a toll it takes on you if you actually care about the environment"

GUYS

PLEASE

The impact of ai on the enviroment is one of the dumbest psyops in history, how can you claim to know start with that after claiming you know the technology and what it is doing?

There are hundreds of reasons to hate ai but this is just NOT it

quite a fun game to bot! got this:

Game over You ran out of time!

You correctly sorted 8389560 numbers.

what does this mean in practice? is everyone being / going to be forced to unlock the devices during the border crossing

Yeah mines been on airplane mode for probably a decade now, really not seeing a reason to ever connect it to the internet

reading this article while listening to billie eilish made me feel something i've never felt before, what a blogpost
