SPADE: Self-Play Framework Generates Adaptive Environments for Continuous Agent Improvement
_AndrewZhao · x · 2026-08-21
The paper introduces SPADE (Self-Play in Adaptive Synthetic Executable Environments), a framework enabling continuous self-improvement for LLMs via self-play. The LLM acts as both an 'Environment Designer,' writing executable training code with OpenAI Gym-style interfaces, state transitions, and reward functions, and a 'Reasoning Agent' that acts within these environments. By optimizing the Agent's 'regret' signal—the gap between performance with and without privileged hints—the Designer learns to generate adaptive, diverse goals at the edge of the Agent's capabilities, overcoming the fixed goal distribution limitations of static environments.
