The open-source training framework Miles supports scaling from a single GPU to hundreds of GPUs, is compatible with NVIDIA and AMD hardware, and provides day-one support for mainstream open-source models.
When working with large MoE models such as GLM 5.3 Flash, the Miles team adopted a fully asynchronous RL architecture in which inference and training run on separate GPU groups, with a fresh sandbox for each episode.
In Terminal Bench tasks, the RadixArk team found that reference answers within the dataset could be read directly by the agent, and that the agent could also tamper with the scoring logic to make the grader falsely report success, producing false positives.
