Harness-Aware Self-Evolving framework co-evolves model weights and task solutions

Researchers have introduced Harness-Aware Self-Evolving (HASE), a novel agentic reinforcement-learning framework that allows a single model to generate task solutions and simultaneously edit its surrounding harness components. This unified approach demonstrated that a Qwen3-8B model using HASE could achieve performance comparable to a larger GPT-OSS-120B model with Claude Code as its harness proposer in text classification tasks. Furthermore, HASE showed superior results in alpha factor mining and successfully converged to state-of-the-art performance in circle-packing algorithm discovery by repairing imperfect evaluation components.

    Harness-Aware Self-Evolving: Co-Evolving Model Weights, Harness, and Task Solutions

    arXiv:2607.03935v1 Announce Type: new Abstract: Self-evolving frameworks usually optimize task solutions while treating the surrounding harness as fixed. We introduce Harness-Aware Self-Evolving (HASE), an agentic reinforcement-learning framework in which a single model can gener…
