MiroThinker
An open-source deep research agent optimized for complex research and prediction tasks, scoring highly on the BrowseComp and BrowseComp-ZH benchmarks.
MiroThinker is a deep research agent optimized for research and prediction tasks. Its latest models score highly on the BrowseComp and BrowseComp-ZH benchmarks, and a smaller MiroThinker-1.7-mini variant sets an open-source state of the art on BrowseComp-ZH while using fewer parameters than earlier full-size releases.
An earlier release, MiroThinker-v1.0, introduced interactive scaling as a way to improve performance by supporting a 256K context window and up to 600 tool calls in a single task, and is available in 8B, 30B and 72B parameter sizes. Online, the hosted MiroThinker product supports generating, previewing and sharing research reports, and accepts uploaded documents in formats such as PDF, Word, PowerPoint, Excel and images.
The project provides benchmark evaluation scripts and trace collection tooling alongside the agent itself, and is released under the Apache 2.0 license.
