you can now train your own coding agents with trl + openenv, starting with opencode

we just added end-to-end support for training agent harnesses:

> TRL: a loop-owning training path (AsyncGRPOTrainer + HarnessRolloutWorker) that launches the agent in an OpenEnv session, reads back its trace, reconstructs the training samples, and trains with AsyncGRPO
> OpenEnv: the OpenCode harness environment plus a transparent proxy that forwards the agent's model calls and records each turn's token ids and logprobs

you train the actual opencode agent as is, it runs its own loop and tools and the policy learns from the exact tokens it produced

we're shipping a self-contained example: local subprocess sandbox, DeepCoder problems, validated on Qwen3-8B.

> example: https://github.com/huggingface/trl/blob/main/examples/scripts/openenv/opencode.py
> docs: https://huggingface.co/docs/trl/main/openenv

and we're working actively on both sides so expect more ๐Ÿค“

join us next Tuesday, July 28, for Class 3 of the Training Agents live series!

we'll dive into reinforcement learning for agent training, covering the intuition behind GRPO, how it works, and how to implement it in TRL with practical, e2e examples

see you there ๐Ÿค

Frontier models use distillation as a step of their post-training pipelines.

In 2026 it has three jobs: compress a big model into a small one, merge RL experts into a single model, and let a model teach itself.

I wrote up which frontier models use each one and how: https://huggingface.co/blog/sergiopaniego/distillation-2026

It pairs with Class 2 of the Training an Agent series Ben and I are doing, where we teach these techniques hands-on with TRL!
