NVIDIA has released Molt, a PyTorch-native training framework for agentic RL.
What it is
- Designed to keep the codebase compact enough for researchers to understand end-to-end.
- Lets algorithm changes flow through a simple, traceable training stack instead of a heavy trainer/backend/glue layer.
Key idea
- The agent remains an ordinary program.
- One asynchronous loop trains multimodal and mixture-of-experts policies while keeping tokens, policy versions, and model semantics aligned.
Why it matters
- The paper argues that leaner infrastructure can improve iteration speed for agentic RL research without sacrificing performance.
- NVIDIA says Molt is open source and ships with recipes and containers.
