Train frontier models with reinforcement learning at scale! Miles is an open-source framework for large-scale RL post-training across LLMs and VLMs. At this scale, RL is not just about choosing an algorithm like GRPO or PPO. You also need fast rollouts, distributed training, weight synchronization, memory management, and a way to keep the training data aligned with what the model actually generated. Miles brings those pieces together. SGLang handles high-throughput rollouts, while Megatron-LM or FSDP2 handles training. Rollout and training can run asynchronously, so generation does not hav
