Modal ships Dojo, a post-training library that turns production agent traces into LLM training runs
Modal released Modal Dojo, a post-training library aimed at teams that already run agents in production and collect evaluations and traces. It bundles model selection, data loading, training recipes and metric observability behind one interface; the official example launches training of Qwen3_8_27B on 120 GSM8K training samples. Built on open frameworks such as Miles and Slime, it is said to be validated on models from half a billion to multi-trillion parameters.
