Great to see the first batch of Slingshots projects from the Laude Institute! We often under-value the work on benchmarks and frameworks, but this is the very foundation of all good AI systems.
Meet Slingshots // One. This inaugural batch includes leading-edge researchers advancing the science and practice of AI - with benchmarks, frameworks, and agents that ship real impact into the world. We're honored to support research from: @alexgshaw @Mike_A_Merrill

Cohere’s models and the fabulous @JayAlammar are hard at work, to help us explore all that NeurIPS 2025 has to offer!
The Illustrated NeurIPS 2025: A Visual Map of the AI Frontier New blog post! NeurIPS 2025 papers are out—and it’s a lot to take in. This visualization lets you explore the entire research landscape interactively, with clusters, summaries, and @cohere LLM-generated explanations

Glad to see the OpenAI team contributing to the OSS community! A lot of great work is enabled by having more and better open-weight models.
gpt-oss is out! we made an open model that performs at the level of o4-mini and runs on a high-end laptop (WTF!!) (and a smaller one that runs on a phone). super proud of the team; big triumph of technology.

I'm excited to be joining the board of the Laude Institute! We need more support and incentives for university researchers who have great ideas and early results to accelerate their work, and build new real-world solutions that have a meaningful impact on people and society.
Today, I’m launching a deeply personal project. I’m betting $100M that we can help computer scientists create more upside impact for humanity. Built for and by researchers, including @JeffDean & @jpineau1 on the board, @LaudeInstitute catalyzes research with real-world impact.

Introducing our first set of Llama 4 models! We’ve been hard at work doing a complete re-design of the Llama series. I’m so excited to share it with the world today and mark another major milestone for the Llama herd as we release the *first* open source models in the Llama 4

Hard to imagine how we went from building AI systems that only a handful of researchers would consider interesting, to helping build our Llama models, which today are in the hands of over 1B people! This is the power of open source – and of amazingly talented teams across Meta.
Llama has surpassed 1 billion downloads 🚀 And we would not be where we are today without the contributions of the entire open source AI community – thanks to each of you who helped make Llama better. We threw together a short recap of some of the amazing things we have built

We released Llama 3.3, a new 70B model that delivers the performance of our 405B model but is easier & more cost-efficient to run, just a couple of weeks ago and the developer community is already finding ways to use it to build better 🔥 Cool work from @NVIDIAAIDev!
🌟 Boost @AIatMeta's Llama 3.3 70B inference throughput by 3x with Tensor RT-LLM optimizations including speculative decoding, in-flight batching, KV caching, custom FP8 quantization, and more. 🦙 Technical deep dive ➡️ https://t.co/BIsmpVGnI8 ✨
