Robostral Navigate

Robostral Navigate is Mistral AI's first model for embodied navigation, introduced July 8, 2026. The 8B vision-language model steers robots through complex environments using only a single RGB camera plus a plain-language instruction, with no LiDAR, depth sensors or multi-camera rigs.

It scores 76.6% on the R2R-CE validation-unseen benchmark, beating the best single-camera approach by 9.7 points and the best multi-sensor system by 4.5 points despite using neither.

Trained entirely in simulation on roughly 400,000 trajectories across 6,000 virtual environments, it generalizes across wheeled, legged and flying robots. Weights are reported as Apache 2.0, making it a notable open physical-AI entry.
