📰 ArXiv cs.AI

Learn how CoSPlay enables cooperative self-play at test-time with self-generated code and unit tests, advancing LLM code generation without ground-truth unit tests

advanced Published 25 May 2026
Action Steps
  1. Implement CoSPlay using Reinforcement Learning with Verifiable Rewards (RLVR) and Test-Time Scaling (TTS)
  2. Generate self-produced unit tests to refine and select code candidates
  3. Apply cooperative self-play to improve code generation
  4. Configure the model to use self-generated code and unit tests
  5. Test the performance of CoSPlay on various coding tasks
  6. Evaluate the results and refine the model as needed
