NVIDIA Cosmos Reason 2: #1 Open Physical AI VLM with 256K Context (16x Increase)
NVIDIA released Cosmos Reason 2 (2B and 8B variants) on the Hugging Face Hub, achieving #1 on both the Physical AI Bench and Physical Reasoning leaderboards as the best open model for robot planning and video analytics. The context window expanded 16x from 16K to 256K tokens, enabling long-horizon robot trajectory reasoning and extended video analysis. Uber is already using it for AV training data, achieving 10.6% BLEU score improvement and 13.8% LingoQA increase — concrete enterprise validation of the physical AI use case.
