# Cosmos Sentinel

Cosmos Sentinel is a traffic-safety demo built around:

- **BADAS** for predictive collision gating
- **Cosmos Reason 2** for causal incident narration and severity labeling
- **Cosmos Predict 2.5** for optional future continuation rollouts in the full project repo

This Hugging Face Space is implemented as a **Gradio app** so it is compatible with **ZeroGPU**.

## What this Space includes

- a polished overview of the project
- a cached sample video for immediate testing
- BADAS + Cosmos Reason 2 live pipeline execution in Gradio
- manual Cosmos Predict continuation rollouts
- model warmup hooks for ZeroGPU-backed startup
- supplementary links to the main papers, repos, and official docs

## Note

The full local Streamlit dashboard remains in the GitHub repo, but this Space now mirrors the core pipeline in a Gradio-first interface tailored for Hugging Face Spaces and ZeroGPU deployment.
