MiroThinker 1.7 Finally Brings Deep Research AI Agents to Open Source

For deep research tasks, the options are mostly proprietary. Perplexity, ChatGPT DeepResearch, paid tools that do the job but keep your data on their servers and charge you monthly for the privilege. Yes you can use open source reasoning models like DeepSeek-R1 or Qwen3 for complex analysis and they are genuinely capable. But they are not built specifically for agentic deep research. They reason well. They do not orchestrate. That gap is exactly what MiroThinker 1.7 is designed to fill. An open source model built from the ground up for long horizon research tasks, step by step verification and up to 300 sequential tool calls without losing the plot. If you handle sensitive research and cannot pipe it through a third party server, this is worth paying close attention to.
