Officials state that Robostral Navigate is trained entirely in simulation using about 400,000 trajectories across 6,000 scenes. The post also highlights a prefix-caching recipe that reduces training tokens by a factor of 22, compressing a process originally measured in months down to days. Additionally, the online reinforcement learning method CISPO further improves the success rate.
