MiroThinker

MiroThinker is MiroMind's Flagship Research Agent Model. It is an open-source search model designed to advance tool-augmented reasoning and information-seeking capabilities, enabling complex real-world research workflows across diverse challenges.

The project currently comprises four key components:

• MiroThinker: An open-source search model that natively supports tool-assisted reasoning, achieving leading performance across multiple benchmarks (e.g., HLE, HLE-Text-2158, HLE-Text-500, BrowseComp, BrowseComp-ZH, GAIA, XBench-DeepSearch, FutureX, and Frames). See Quick Start.
• MiroFlow: An open-source research agent framework that offers reproducible state-of-the-art performance across multiple benchmarks. See MiroFlow for details.
• MiroVerse: A premium open-source training dataset with 147k samples supporting research agent training. See MiroVerse on HuggingFace.
• MiroTrain / MiroRL: Training infrastructure that supports stable and efficient training for research agent models. See MiroTrain and MiroRL for details.
