## Model description
This model uses Meta Plan Optimization (MPO) to improve the planning capabilities of LLM agents. It leverages high-level general guidance through meta plans and enables continuous optimization based on feedback from the agent's task execution. It achieves state-of-the-art performance on ALFWorld and SciWorld, with an average accuracy of 83.1.
