Details
MiroThinker-1.7, an open-weight deep research agent built on Qwen3 MoE, has been released.
The model is available in two versions:
- MiroThinker-1.7: the full model.
- MiroThinker-1.7-mini: a MoE structure with only 3B of 30B total parameters activated, aimed at efficient operation on consumer hardware.
Technically, it uses a proprietary context management strategy leveraging a sliding window (K=5) and episode restarts.
In benchmark results, MiroThinker-1.7 records strong performance on GAIA (82.7) and xbench-DS (62.0), competing with Qwen3.5-397B and DeepSeek-V3.2. The model weights are available on HuggingFace, and detailed research can be found in the paper arXiv:2603.15726.
