### Highlights

* **Benchmark-leading performance**: On arXivQA, the index hits 53.3% recall versus 45.4% for the next best provider. The index also scores 0.750 MRR, putting the right paper in the top one or two results.
* **Search millions of papers alongside their code**: The index includes 3M+ arXiv papers, plus GitHub artifacts from top research repos (issues, merged PRs, READMEs), refreshed daily.
* **A complete toolset for research loops**: Agents can retrieve papers, verify claims against full text, and pull code, going from literature to implementation with no manual review.
* **Plugs into any agent harness**: Works with Codex, Claude Code, Grok Build, and more.
