On average, RAG, MCP, and NLWeb reach about 0.75 F1, while HTML stays near 0.67 and misses more. HTML agents also burn more compute, needing about 3x more tokens and 5x more time per task than others. So the study recommends RAG agents, often with GPT5 or cheaper GPT5 mini, and keeping HTML browsing only as backup. -- (Steiner et al. 2025)
