The Hub is quiet on big base model drops. Black Forest Labs shipped a small open world action model. NVIDIA added posts on diarization and GPU simulation. The day leans to tooling and robotics.
On the Hub
FLUX 3 Action
Black Forest Labs posted about FLUX 3 Action on September 23.1 It is a 7B world action model for robot policies. It takes camera frames and text instructions and predicts about two seconds of actions. Repos appeared on September 22 under FLUX Kommunity License v1.0. RoboLab reports 42.92 percent success on its test set, ahead of Cosmos 3 Nano policy at 36.8 percent.
Nemotron 3 Diarization
NVIDIA posted about Nemotron 3 Diarization on September 23.2 The model card lists a release date of September 23, 2026. The Hub repo was created on September 1. It is 100M parameters and handles up to eight speakers with overlap under OpenMDW 1.1. VoiceArena Diarization-Bench reports 14.72 percent DER for the author system.
NVIDIA Warp and MjWarp
NVIDIA published an Enterprise Hub article on September 23 about Warp and MjWarp.3 It shows how to move a MuJoCo SO-101 pick and place scene to GPU batched simulation with MJWarp. It covers pip install warp-lang and pip install mujoco-warp. It scales to up to 2,048 worlds with CUDA Graphs.
