Meta has released SAM 3.1, an update to its Segment Anything Model that adds Object Multiplex, a shared-memory approach for joint multi-object tracking. The new version achieves approximately 7x faster inference when tracking 128 objects on a single H100 GPU while improving video object segmentation (VOS) performance on 6 out of 7 benchmarks.

Xiaomi released MiMo-V2-Pro on March 18, 2026, a flagship foundation model with over 1 trillion total parameters and a 1,048,576 token context window.
