Choose ROLL if…

  • Tags unique to ROLL: agentic, 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 SPPO if…

  • Tags unique to SPPO: deep-learning, fine-tuning, large language models, self-play.
  • Also covers LLM Frameworks.
  • Use if you aim to specialize in fine-tuning large language models with self-play techniques and reinforcement learning for enhancing model preferences.

When NOT to use SPPO

  • Avoid SPPO if your project does not require or benefit from reinforcement learning mechanisms or the fine-tuning specifics provided through self-play methods.
  • Do not use SPPO in scenarios where simpler model tuning approaches without self-play are adequate for achieving project goals, as it might introduce unnecessary complexity.
