Llama 2 is out! ai.meta.com/llama This new version has better language generation, more layers of safety, a broad set of partners – and a license that authorizes commercial use. I continue to believe that an open approach is the right path to build better models!

How many of the signatories have used their expertise, their influence, their resources to rigourously analyze and expose the risks of current AI systems, and to build solutions that address real harms? That is what we need. Not letters, headlines and inflammatory statements.

The notion of "object" (or "concept") is contextual and controllable. Segment Anything allows a greater degree of expressivity than anything we've done before, and is open-sourced for anyone to try. Exciting to see what this will enable, in terms of broader scientific discovery!

Today we're releasing the Segment Anything Model (SAM) — a step toward the first foundation model for image segmentation. SAM is capable of one-click segmentation of any object from any photo or video + zero-shot transfer to other segmentation tasks ➡️ bit.ly/433YuBI

There are so many good use cases for large models. Great to see the Galactica project from FAIR coming out, with our usual high standards for open science: paper, model, demo, and more!

Another strong model released by our FAIR research team. This model is more general than Segment Anything (released earlier this month) and just as full of potential to power new applications of AI!

Happy to share details about Stable Signature, an invisible watermarking technique to distinguish images created by open source generative AI models, from FAIR &INRIA. It's another step towards building tools for safety and responsibility in generative AI.

Stable Signature: A new method for watermarking images created by open source generative AI
Invisible watermarking incorporates information into digital content. The watermark is invisible to the naked eye but can be detected by algorithms—even if people edit the images.
