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…

  • Pricing: OpenRLHF is primarily available free of cost under the Apache-2.0 license, but users might incur costs based on their infrastructure usage for distributed training setups (e.g., cloud GPU instances)..
  • Tags unique to OpenRLHF: large language models, proximal-policy-optimization, raylib, reinforcement-learning.
  • Also covers Inference & Serving.
  • When you require high-throughput sample generation with minimal idle time on limited hardware due to its hybrid engine scheduling that enables sharing of GPU resources between models and vLLM engines.

When NOT to use OpenRLHF

  • If your project does not require distributed training or large-scale model parameters (above 70B), as OpenRLHF is specifically optimized for scenarios where efficient distribution across multiple GPUs
  • When your environment cannot support Ray or vLLM, as these are crucial components of the framework for scheduling and high-performance sample generation, respectively.
  • If minimal Docker setup and hardware requirements with GPU constraints are not acceptable in your scenario.
