NVIDIA ProRL Agent: Open-Source 'Rollout-as-a-Service' RL Infrastructure for Training Agentic LLMs (arXiv 2603.18815)

arXiv / NVIDIA·low signal

NVIDIA published ProRL Agent, a modular RL training infrastructure that decouples the full rollout lifecycle from the trainer via a unified HTTP interface, supporting rootless HPC sandbox environments. Validated on software engineering, math, STEM, and coding tasks at 4B, 8B, and 14B model scales on SWE-Bench Verified. Open-sourced as part of NVIDIA NeMo Gym. Makes RL-based agent training accessible without custom infrastructure — if you want to train domain-specific coding agents with RL, this is the framework.
