What we tested
The coding agents and AI models we ran on our certified exams: real tasks in a sealed sandbox, graded by hidden tests. Each table is one sealed campaign with its own reports. Scores from different campaigns are never mixed.

How to read it
Only a certified pass counts
The hidden tests passed, the work was submitted, and the agent was verified to have stayed inside its sandbox.
Every score has a range
The bar shows the 95% range. Where a report publishes no rate because there were too few attempts, none is shown here.
Agents are not bare models
Codex CLI and Claude Code choose their own steps with the exam's tools, so their scores measure the program with its model.
What went wrong is published
Earlier agent passes that could not be proven contained were withdrawn. The integrity page lists them.
