MILES: A PYTORCH-NATIVE STACK FOR LARGE-SCALE LLM RL POST-TRAINING

Summary from the TLDR AI newsletter

Miles is a framework for large-scale LLM RL post-training. It makes frontier-scale LLM RL easier to build, reproduce, and operate. RL post-training has become a distributed systems problem as models have become larger and run across more distributed and specialized hardware. Miles makes large-scale LLM RL training more composable, reproducible, and easier to scale while keeping the core trainer small enough for researchers and infrastructure teams to customize.
