Open methods

Our evaluation suite, red-teaming methodology, and interpretability tooling are published. You can reproduce our claims.

Published evals

Every model release comes with a report of what was tested and what was not. No cherry-picked numbers without context.

Corus for deep work

Frontier capability is free to researchers, within fair-use limits. Expensive thinking should not be rationed for the people studying it.

Collaboration, not access

Interpretability work at Curos is open to outside contributors, and findings are published under permissive licenses.

Reproducing a claim

A grad student reads our interpretability paper on feature geodesics and wants to check the 82%-versus-61% classification result against their own model. The paper links the evaluation methodology and prompt set we used, and Corus is free enough, with high enough fair-use limits, to actually run the comparison rather than budget for it.

When their number comes out different, they open an issue through the research contact channel rather than just quietly disbelieving the paper — and if the gap turns out to be a real methodological difference, that becomes the seed of the next paper, credited to both teams.

Common uses

  • Reproducing evaluation results from our release reports
  • Studying interpretability findings on real models
  • Running red-teaming rounds as part of course or lab work
  • Drafting, analyzing, and stress-testing research hypotheses
  • Building on our published methods for efficiency and alignment

Getting started

Start with the research index and the evaluations page to understand what we publish, then use the free product for your own experiments. If your lab wants to build on our tooling or run a formal red-teaming round with us, reach out through the research channel on the contact page.

Everything on this page is part of the Curos concept project. There is no real program, and the scenarios above are illustrations of how a free, non-profit assistant could serve each audience.
