Never heard so many standout infra engineers + AI infra eng actively wanting to leave Meta than now. A month ago they were building cutting-edge infra and then got assigned to AI data labelling Most of them went “WTH” and now I’m the middle of interviewing Madness from Meta

i just want to shake people awake. this is it! the computers are speaking! they solve Erdos problems! they think for hours! code is no longer hand-written! wake up! gradient descent on deep neural networks shows no sign of plateau! this is it!

bro it isn’t generally intelligent bro its only read every book and paper ever written and just making connections between them bro. its only thinking for twenty hours bro it’s just brute force thinking bro. its only solving erdos problems bro it could never be an accountant bro

Align with how @cursor_ai has done its RL stage — Astraflow is a new RL engine that enables asynchronous, heterogeneous, and geo-distributed RL in a native way through dataflow abstraction~ Like @FireworksAI_HQ’s sparse RL transfer design, it syncs only ≤1.1% of model weights — making remote rollout lightweight and efficient. Check it out!!!

Personal update: I've joined Anthropic. I think the next few years at the frontier of LLMs will be especially formative. I am very excited to join the team here and get back to R&D. I remain deeply passionate about education and plan to resume my work on it in time.

The bitter lesson in 26 words: Don’t be distracted by human knowledge, as AI has been historically. Instead focus on methods for creating knowledge that scale with computation, like search and learning.

🚀 BLASST just won Best Paper at #MLSys26! In this paper, we introduce a simple, training-free dynamic sparse attention mechanism that uses a single scalar threshold on online softmax statistics to skip negligible attention blocks. Unfortunately I won’t be there in person, but please say hi to my awesome coauthors! 🙌 Paper: arxiv.org/abs/2512.12087

I can’t stop thinking about this post. If you do one thing today, I encourage you to give it a thoughtful, thorough read… And then commit to never living your life this way. Life has wasted success on the people described in this post. It really is completely pathetic. They say that comparison is the thief of joy - look no further than this post for validation it is indeed true. On their deathbed they will realize they have lived their life completely wrong. Don’t let it be you.

The vibes in SF feel pretty frenetic right now. The divide in outcomes is the worst I've ever seen. Over the last 5yrs, a group of ~10k people - employees at Anthropic, OpenAI, xAI, Nvidia, Meta TBD, founders - have hit retirement wealth of well above $20M (back of the envelope

Today marks 1 week since we introduced Altara @altaratech to the world! We hosted a launch celebration to thank all our friends, mentors, and supporters who’ve been in our corner long before the launch. Behind the scenes, it takes a village - and we couldn't ask for a better one. Special thanks to @GreylockVC for hosting such a great night 🥂

Last week, Altara took over the Greylock SF office! @evatuecke, @catherinehyeo and the team came out of stealth, so a party was in order. They are one of the most hardworking and talented teams we've had the privilege of partnering with, bringing AI to the world of physical sciences. Seeing the team finally get to celebrate in a room full of people who've been rooting for them from day one made us so proud. Big congratulations to everyone at @altaratech cc @GreylockVC

There is no pre-training, post-training, or test-time training. There are only priors, updates, constraints, and compute budgets. There is only TRAINING. Last several years we shipped the org chart to fundamental optimization science.
