Choose ROLL if…

  • Tags unique to ROLL: agentic, rlhf, rlvr.
  • Also covers Evaluation & Observability.
  • When developing reinforcement learning applications requiring integration of large language models, offering efficient scalability solutions.

When NOT to use ROLL

  • Avoid for tasks that prioritize minimalist setups over advanced feature integrations like Alibaba Cloud Function Compute DevPods.
  • Not suitable if you prefer tools without built-in support for converting models between MCoreAdapter and Hugging Face formats.

Choose OpenRLHF if…

  • Tags unique to OpenRLHF: large-language-models, proximal-policy-optimization, raylib, reinforcement learning.
  • Also covers Inference & Serving.
  • When you need to train large models up to 70B+ parameters with efficient distributed scheduling and high-performance inference.

When NOT to use OpenRLHF

  • If your project does not require support for large models or distributed training, as OpenRLHF's complexity and resource requirements may be unnecessary.
  • When you prefer a framework that does not rely on Ray for distributed scheduling, as OpenRLHF's architecture is tightly coupled with Ray for its distributed capabilities.
