A Rubric-Supervised Critic from Sparse Real-World Outcomes

Researchers propose a new framework called Critic Rubrics to bridge the gap between academic coding agent benchmarks and real-world applications. The system learns from sparse, noisy human interaction data using 24 behavioral features and shows significant improvements in code generation tasks including 15.9% better reranking performance on SWE-bench.

No More Stale Feedback: Co-Evolving Critics for Open-World Agent Learning

Researchers introduce ECHO, a reinforcement learning framework that co-evolves policy and critic models to address the problem of stale feedback in LLM agent training. The system uses cascaded rollouts and saturation-aware gain shaping to maintain synchronized, relevant critique as the agent's behavior improves over time, demonstrating enhanced stability and success rates in complex environments.
