1/ today we're releasing muse spark, the first model from MSL. nine months ago we rebuilt our ai stack from scratch. new infrastructure, new architecture, new data pipelines. muse spark is the result of that work, and now it powers meta ai. 🧵

An exciting milestone for AI in science: Our C2S-Scale 27B foundation model, built with @Yale and based on Gemma, generated a novel hypothesis about cancer cellular behavior, which scientists experimentally validated in living cells. 

With more preclinical and clinical tests, this discovery may reveal a promising new pathway for developing therapies to fight cancer.

Nice! Also Gemma and in particular Gemma 3 1B 👨‍🍳🤌😍

[Thomas Mesnard @Mesnard_Thomas]

Thrilled to announce the world’s most capable differentially private LLM!

Huge congratulations to the entire team — and special kudos to Amer Sinha for his outstanding contributions.

Take a look!

VaultGemma is a release of an open model trained from scratch with differential privacy.

The blog post below and the full tech report linked from the tech report have some nice analyses to present a scaling law for differentially private language models:

Introducing EmbeddingGemma, our newest open model that can run completely on-device. It's the top model under 500M parameters on the MTEB benchmark and comparable to models nearly 2x its size – enabling state-of-the-art embeddings for search, retrieval + more.

[Omar Sanseviero @osanseviero]

Introducing EmbeddingGemma🎉

🔥With only 308M params, this is the top open model under 500M
🌏Trained on 100+ languages
🪆Flexible embeddings (768 to 128 dims) with Matryoshka
🤗Works with your favorite open tools
🤏Runs with as little as 200MB

We've had a busy August!

[Thomas Mesnard @Mesnard_Thomas]

🚀 After Gemma 3 1B, we’re going tiny: Gemma 270M — fast, on-device, low-power & privacy-first.

A new vision: smaller models with strong instruction-following & finetuning, ideal for low-latency edge apps & automation.

Congrats to everyone involved!

Introducing Gemma 3 270M 🔥

🤏A tiny model! Just 270 million parameters
🧠 Very strong instruction following
🤖 Fine-tune in just a few minutes, with a large vocabulary to serve as a high-quality foundation
