Reinforcement Learning (GRPO) Support
Real-time help with GRPO — TRL’s GRPOTrainer with vLLM-accelerated generation, reward-function design, group size and KL control, and stable RL post-training for reasoning and verifiable tasks.
Running GRPO to train a reasoning model and fighting reward hacking, collapse, painfully slow generation, or OOM? GRPO is the current workhorse for RL post-training with verifiable rewards, but it has real operational challenges. We help you run it well.
Group Relative Policy Optimization is an online RL method (stable in TRL v1) that samples a group of responses per prompt, scores them with a reward function or verifier, and updates the policy toward the relatively better ones — no separate value model needed. It shines for reasoning and tasks with a checkable answer. We help with reward-function design (verifiable rewards, format rewards, avoiding exploitable shortcuts), vLLM-accelerated generation setup (the usual bottleneck), group size, KL/temperature control, PEFT integration, and diagnosing collapse or reward hacking. TRL integrates with OpenEnv for richer RL environments.
