@rowancheung I wouldn’t say unlimited cooling.. I remember Carl Schulman on Dwarkesh’s pod talking about boiling the oceans as a limit of gdp growth

There's a startup trying to build data centers in the ocean. And it's INCREDIBLY fascinating: Mass consumption of electricity and water is a growing bottleneck for data centers. So by moving offshore, it eliminates both problems -- the ocean provides unlimited cooling, and the waves provide unlimited power. There are also no engines, so the data centers drive themselves to their destination by using the shape of their hull to propel through waves. Called Panthalassa.

I gave Fable 5 one job: write custom WebGPU kernels for Gemma 4 inference. It climbed to 84 tok/s, then hit a wall, insisting further optimization was impossible. Hours later, Anthropic rolled back invisible LLM development safeguards, and it hit 255 tok/s. The next day, access to Fable 5 was suspended globally.

If we are at the point that Anthropic is degrading performance for any sort of meaningful research in biology, chemistry, or computer science… Maybe it really is over?

Programming has already changed dramatically. On my best days - I literally feel IO bandwidth limited managing the concurrent threads. As the models get better the level of abstraction will keep going up - very soon the models will only come to us for hard calls. Eventually - they won't come to us at all. LOC is obviously a terrible metric, but is correlated

@blakeandersonw Thanks for sharing. Does this experience reinforce your understanding of Jesus as an awakened human or something else?

I just did DMT for my second time. Will share a few of my thoughts below. Feel free to ask me anything.

@Miles_Brundage New llm benchmark

In retrospect this joke was too subtle for those reading quickly

Personal update: I've decided to join Anthropic in continuing to be based in SF

@karpathy weirdest TL

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.

Starting today, you can run cloud agents inside fully configured development environments. Set them up the same way you'd set up a laptop for an engineer: cloned repos, installed dependencies, and toolchain credentials.

no bro you need to turn on “/extrausage”. dawg are you sure you have “/fast” mode on? Did you check the “no mistakes” toggle? are you sure you picked “correct mode”? did you turn up the “autonomy slider”, that’s how the pros use it,

@nptacek As long as it passes the test suite or other objective verifier it doesn’t matter if it’s synthetic or not

i have never understood the synthetic data skeptics it's like they haven't played around with models at all, just stuck to whatever the prevailing view was

@tszzl you need to be termiusmaxxing (mine is running sweet! cli agent)

people are walking around with their laptops slightly ajar to keep their agents running

@ClaudeDevs forcing everyone else to be more creative. we need it

For the developers building with Claude, a direct line from the team. Follow for changelogs, API releases, community updates, and deep dives.

Today we’re announcing Ternary Bonsai: Top intelligence at 1.58 bits Using ternary weights {-1, 0, +1}, we built a family of models that are 9x smaller than their 16-bit counterparts while outperforming most models in their respective parameter classes on standard benchmarks. We’re open-sourcing the models under the Apache 2.0 license in three sizes: 8B (1.75 GB), 4B (0.86 GB), and 1.7B (0.37 GB).

@bstnxbt how many cli agents could you run in parallel on that machine?

Qwen3.5-4B just hit 133 tok/s on my M5 Max baseline MLX does 42 tok/s, so 3.2x with same output

how it feels to accept that reality is just a carbon-based simulation where your infinite consciousness gets to play as a human avatar and remember itself as the creator of all experience despite the inherent limitations of a fragile physical existence
