DeepSeek Unveils Autonomous Coding Agent Prototype

We asked Mistral Large 4 to show what happens when you break a molecule. ⚛️ With a short prompt, it wrote a quantum chemistry SCF solver from scratch, validated its output, and built a 3D view around it. Le Chonk also understand chemistry enough to...

"One Model to Loop Them All: Elastic Latent Recurrence for Language Models" Looped Transformers typically perform much worse than standard models when looping only once. NVIDIA introduces Elastic Latent Recurrence (ELR), which uses gated state updates and...

Today we’re releasing GDPx, a benchmark for measuring agentic capabilities across the most valuable domains. GDPx is a true frontier-level benchmark: even the best model scores just 12% (1/7)🧵

Last week in Tokyo, we hosted the Sakana AI Symposium with our Chief Scientific Advisor, Jürgen Schmidhuber. Eight years ago, @SchmidhuberAI and I wrote the "World Models" paper together. Today, we’re building on those foundations at our RSI Lab to train...

Introducing Hacker Papers! I absolutely love this HackerTube idea from @karpathy. So I took his prompt and similar data sources and asked my agent to build the arXiv papers version of it. Absolute bangers there. Find all 1K+ papers here:

Some things I often say to Claude when doing perf optimization work: > how do we rewrite this to better leverage data-oriented design principles > can you replace those hash tables with a flat array? can we make the pointers an index into the array? can we...

The AI compute situation - data center build out delays will continue - US is power constrained - GPUs demand will be sky high - spot will be 3-5x that of existing contract prices The biggest losers will be folks with existing compute contracts that they...

You can enable this on Replit with one toggle. If you enable the “feedback widget” on your site, users’ feedback become prompts for the agents to build.

GPT-4 could do 4 minutes of independent work with a 50% chance of success. Current models can do multiple weeks of work, and January 2026 is a reasonable cut-off for the moment agentic work started. Large productivity impacts before that would mostly be...

HackerTube. I was annoyed with YouTube's recommendations so I had Claude filter down 43M comments over 20 years of HN to 6,454 videos that keep being recommended. *Significantly* better viewing experience, ~2 hours with Opus 5.5: - Excellent recs without any logins (state is kept in local browser session) - Thumbnail is a representative frame from middle of the video instead of the super duper A/B test hyper-optimized user uploads - Underlying data from the comment analysis as one zip file, point your Claude at it and ask for your own version - HackerTube Longs ✊ A bit more on the process: I use Claude Code (desktop app for Mac), Opus 5.5 on Medium effort as my default. I only talk to Claude and have it do everything, the only "manual work" I helped with in tandem was in the browser (reminiscent of MenuGen): 1) I had to create some kind of API key from Google Cloud UI to query YouTube for video metadata, 2) I booted up a VPS box for serving and 3) I bought the domain name. Once the box was up I gave Claude the IP and told it update, secure, harden, deploy and optimize the code, and it did the whole thing. Many awesome projects that would have normally taken weeks/months even can now be few-shotted for breakfast. What else are we not thinking of.
