## What stands out

- Single-RGB-camera vision-language navigation: 8B model navigates buildings from one RGB camera plus language instructions (no LiDAR/depth); R2R-CE success 79.4% val-seen, 76.6% val-unseen (+9.7 pts over best single-camera method, +4.5 over depth/multi-camera systems). Source: https://mistral.ai/news/robostral-navigate/
- Sim-only training, embodiment-agnostic: Trained in simulation (~2.4M trajectories across 350k scenes per Mistral's page), with prefix caching (22x fewer training tokens) and online RL (CISPO, +3.2 pts); works on wheeled, legged and flying robots.
