What people said about Introducing FrontierHarness Eval on X
Codex had the highest pass rate in Runta's harness eval: 66.7% across 30 tasks. Small sample, but still useful to see what changes when you keep the model fixed and swap the tools and agent loop around it. https://runta.com/blog/introducing-frontierharness-eval/
