Wrote an in-depth blog on Scaling Modern Transformers with n-D parallelism. Includes an explanation with code on how modern-day transformers (multi-latent attention, decoupled RoPE, interleaved-attention, mixture-of-experts, etc.) are built across a multi-node TPU cluster.
home for the next 4 months! starting my internship to work on RL @AmazonScience Nova Act in sf! reach out if ur in the city :)
man enters sf for 3 hours and immediately encounters cluely ad wouldn’t have it any other way
Everyone saying AI is going to replace people clearly don’t work with great people enough
the great lock in of 2025 starts tmr
the people with the most useful domain expertise are not the weekend-warrior agent hackers or PhD dropouts. they're doctors and lawyers and accountants and bankers and professors. we need to teach them how to do this.
Introducing Grok Code Fast 1, a speedy and economical reasoning model that excels at agentic coding. Now available for free on GitHub Copilot, Cursor, Cline, Kilo Code, Roo Code, opencode, and Windsurf. x.ai/news/grok-code…

Introducing the Environments Hub RL environments are the key bottleneck to the next wave of AI progress, but big labs are locking them down We built a community platform for crowdsourcing open environments, so anyone can contribute to open-source AGI
Early this summer, OpenAI and Anthropic agreed to try some of our best existing tests for misalignment on each others’ models. After discussing our results privately, we’re now sharing them with the world. 🧵
Introducing The Darwin Gödel Machine: AI that improves itself by rewriting its own code sakana.ai/dgm The Darwin Gödel Machine (DGM) is a self-improving agent that can modify its own code. Inspired by evolution, we maintain an expanding lineage of agent variants,…
i remade tiny-tpu to support both inference and training! we successfully tested our architecture on the classic XOR problem. here's what i learned throughout the process:👇

introducing "the repository" where i'll be writing on different "slightly-advanced fundamentals" and basics of design engineering. marcelochaman.ca/repository there are 10 write-ups already. what do people want to read about?
we’re hiring ai researchers, engineers, growth, interns etc at @PrimeIntellect ping me if you want to work on open agi & frontier research infra for everyone
We just raised a $9.4M seed round to seize the means of production of software. Turns out, it fits in your pocket. @vibecodeapp (Thread)
Today, we're announcing our first hosted infrastructure product: pyx, a Python-native package registry. We think of pyx as an optimized backend for uv: it’s a package registry, but it also solves problems that go beyond the scope of a traditional "package registry".
shadow is an open-source background coding agent with a real-time interface and codebase context system here's a breakdown of how it works ⬇️
Claude Sonnet 4 now supports 1 million tokens of context on the Anthropic API—a 5x increase. Process over 75,000 lines of code or hundreds of documents in a single request.
