- Meta's Segment Anything Model 3.1 is now live on the Meta Model API, an official implementation with inference tuned for the model's architecture.
- A noun-phrase prompt finds objects in images and video; one API call returns detections, pixel-precise masks, and identity-preserving video tracks, sharing the same API surface, billing and auth as other Muse models.
- Pricing is $2.50 per 1,000 images and $0.20 per 1,000 frames; open weights remain available on Hugging Face.
