    In past months I saw some posts saying Reasoning models cannot do agent tasks. Try Grok Deepsearch that combines the world of two for free 🚀

    🤔 How to let Large Language Models (LLMs) agent utilize diverse tools via Tree Search 🔍? In AVIS, we enable LLM Agent to dynamically traverse a transition graph with self-critic (when one path is not informative, backtrack to previous state). This achieves SOTA VQA result.

    AVIS employs a dynamic decision-making strategy to respond to visual information-seeking queries.

    Can LLMs play a hidden-identity board game "Renaissance Avalon"? Check out: arxiv.org/abs/2310.05036 Code: github.com/jonathanmli/Av… In this work, we built a game engine AvalonBench, consisting of several fixed rule baselines. We found ChatGPT 3.5 still cannot beat simple rules.
