🚀 Introducing SaulLM-141B and SaulLM-54B: The First Open Family of Legal Models. After #SaulLM-7B the family is growing! We are proud to unveil the latest innovations from our team: the SaulLM-141B and 54B generative AI models, specifically designed for the legal domain.

Should you waste tokens having your coding agent use grep, or hand the search to a tiny local model? We release ColGrep-Agent-2B! A code-search agent that runs locally, searches with ColGrep, reads files, & returns locations + code to your main agent -> 34% fewer API tokens

BidirLM-Omni is live right now at COLM poster #28! Looking for an open source encoder training method that sits right on the Pareto frontier alongside @googlegemma recent omnimodal embedding? Come talk to us! 🚀

Huge congrats to @N1colAIs @theodb_ml and @gisship 🎉 @GoogleDeepMind just released EmbeddingGemma 2, and the @googlegemm launch blog benchmarks against BidirLM-Omni-2.5B on the Massive Audio Embedding Benchmark. Our model sits right on the Pareto frontier!

I'm at #COLM2026 in San Francisco this week 🌉 I will be presenting BidirLM-Omni (/w @N1colAIs) open-source recipe that turns causal decoder LLMs (like Gemma 3 and Qwen3) into strong bidirectional encoders for text, image and audio

🔥 Accelerate your diffusion LMs with Distribution Matching Distillation Introducing two methods for continuous diffusion LMs with gains at complementary sampling budgets: 🔺 Simplex-DMD at very few-step budgets 🎲 Reinforce-DMD at larger budgets 🔺 At 4 NFEs Simplex-DMD halves the strongest baseline’s generative perplexity at matched entropy (1/n)

I joined Google DeepMind last week to work on (hopefully) improving the Gemini models! The past few years have been incredibly fun and rewarding - working on great projects with amazing people whom I'll never thank enough. Excited to discover what lies ahead!

Awesome to see them build on the same tricks as BidirLM-Omni, like the decoder-to-encoder adaptation and cross-modality model merging. The synthetic data ablation is also a huge highlight with a +15 gain for code retrieval domains
