What It Is
4ort Agentic Deep Research is a deep-research agent built on the open-source MiroThinker framework (Apache-2.0), with one defining move: every vendor tool is swapped for lab infrastructure. Search goes through the 4ort smart router, reading goes through the 4ort fetcher, code execution runs in the lab sandbox. The whole research toolchain is self-hosted.
The claim isn't taken on faith; it's benchmarked. On a 50-task FRAMES subset, the lab-tooled agent scores 82% → 84% pass@1, at or above the vendor-tooling baselines. Swapping the vendor stack for self-hosted infrastructure didn't cost accuracy; it matched and edged past it.
In production it runs as a 5-worker concurrent pool with four depth tiers, from ~10-second "flash" answers up to deep multi-hour research. It's the same agent, dialed to however much rigor the question deserves.
Highlights
- All-lab toolchain: search via the 4ort smart router, reading via the 4ort fetcher, code-exec via the lab sandbox. No vendor tools
- 84% pass@1 on FRAMES (50-task subset), up from 82% and landing at or above the vendor-tooling baselines
- Benchmark-proven: the self-hosted swap is validated on public benchmarks, not vibes
- Four depth tiers: from ~10-second "flash" answers to deep multi-hour research
- 5-worker concurrent pool: multiple research jobs in flight at once
- Open foundation: a 4ort overlay on an Apache-2.0 open-source research framework
