Researchers have introduced EvoGenUI-Bench, a new benchmark designed to evaluate Large Language Models (LLMs) in their ability to act as multi-turn generative UI assistants. The benchmark consists of 150 five-turn tasks across three scenarios: information presentation, executable interaction, and tool-grounded external state. Evaluation involves executing generated artifacts in a browser and assessing them through various metrics including turn-level success, episode-level completion, and cross-turn retention. Even the top-performing models struggled, with the strongest achieving only 74.9% Turn Pass and 37.3% completion for five-turn episodes, highlighting challenges in maintaining synchronized interface behavior, derived state, and external state as the artifact evolves.
