TRL Adds Native Agent Trace Training Support Alongside 2,000+ SynthTraces Dataset
June 4, 2026
HuggingFace's TRL library is adding official support for training on agent traces via `trl sft --dataset-name`, coinciding with datasets v5 and the SynthTraces release of 2,000+ coding agent session traces generated using two-model interactions on real HuggingFace OSS codebases.
HOW THIS AFFECTS YOU
●
builderYou can now fine-tune your own coding agent using a one-liner with TRL and the SynthTraces dataset — no custom data pipeline needed to get started with agent trace training.
●
researcherSynthTraces provides a reproducible two-model harness for generating coding agent traces at scale, useful as a baseline or augmentation source for agent behavior research.
