MiRA Supercharges Open LLM Agents Past GPT-4
Researchers propose a subgoal-driven framework and MiRA RL method to tackle long-horizon planning in LLM agents for web navigation. MiRA elevates Gemma3-12B's WebArena-Lite success rate from 6.4% to 43%, outperforming GPT-4-Turbo (17.6%) and GPT-4o (13.9%). This combo of planning and milestone rewards boosts autonomous AI capabilities.
