WebGrader trains LLMs for web development with self-evolving grader

Researchers have introduced WebGrader, a novel system designed to train large language models for web development tasks. This self-evolving programmatic grader autonomously generates interaction flows from website requests, representing them as executable Flow Contracts. By separating test planning, action grounding, evidence collection, and semantic judgment, WebGrader ensures verdicts are issued only after observing the complete transition, leading to improved functional success rates on benchmarks like WebGen-Bench and WG-core-250.
