June 2026 performance summary: Delivered Cosmos3 Action Modality and Policy Support for vllm-omni, enabling action generation and forward dynamics, integration of action data into the multimodal framework, and action policies to guide autonomous and interactive tasks. No major bugs fixed this month. This work expands the product's capabilities for action-enabled multimodal workflows, improving deployment flexibility and user outcomes. Key tech skills demonstrated include multimodal modeling, action modality, policy integration, forward dynamics, and collaborative code contributions.

December 2025 (nvidia-cosmos/cosmos-rl): Key features delivered and bugs fixed with a focus on hardware compatibility and MoE reliability. Achieved stability for legacy GPUs by disabling DeepEP on architectures older than Hopper, and corrected MoE routing by fixing n_local_experts computation for DeepseekV3 and Qwen3. These changes reduce edge-case failures, improve performance and efficiency, and support broader deployment across GPU architectures.
