SAM 3.1: Meta Releases Faster Real-Time Video Segmentation Model with Object Multiplexing
Meta has released SAM 3.1, an incremental update to Segment Anything Model 3, introducing object multiplexing that allows tracking up to 16 objects in a single forward pass. This doubles video processing throughput from 16 to 32 FPS on a single H100 GPU, reducing GPU resource requirements and enabling real-time tracking on smaller hardware. SAM 3.1 is a drop-in replacement for SAM 3 and is available via updated model checkpoints and codebase. The broader SAM 3 release also includes text and exemplar prompting, a new Segment Anything Playground, the SA-Co evaluation dataset, and SAM 3D for 3D reconstruction.
Anthropic submits detailed recommendations to strengthen US AI chip export controls under Diffusion Rule
Anthropic filed a formal response to the Department of Commerce's 'Framework for Artificial Intelligence Diffusion' interim final rule, advocating for stronger export controls on advanced semiconductors to preserve US AI leadership. Key recommendations include adjusting the three-tier country classification system, lowering the no-license compute threshold for Tier 2 countries, and increasing enforcement funding for the Bureau of Industry and Security. Anthropic argues that Chinese firms like DeepSeek demonstrate export controls are working but warns of aggressive chip stockpiling and smuggling operations that undermine their effectiveness. The submission frames compute advantage as a national security imperative, warning that without strong controls, frontier AI infrastructure could offshore similarly to solar panels and semiconductors.
