Mistral AI introduces Robostral Navigate, an 8B model for embodied navigation using a single RGB camera. It achieves state-of-the-art performance on R2R-CE benchmarks, outperforming multi-sensor approaches. The model is trained in-house using simulated data and token-efficient techniques like prefix-caching, and further improved with online reinforcement learning (CISPO). It generalizes across robot types and adapts to real-world obstacles, combining pointing-based navigation with local displacement fallbacks.

Introduces Robostral Navigate, an 8B embodied navigation model utilizing a single RGB camera. Achieves 76.6% success on R2R-CE unseen benchmarks. Employs pointing-based navigation and local displacement fallbacks. Trained in-house on 2.4 million trajectories from 350k simulated scenes using prefix-caching for efficient supervised training (22x token reduction). Further improved with CISPO online reinforcement learning, boosting success rate by 3.2%. Generalizes across robot types and adapts to unseen real-world obstacles.
