# Does a high FrontierCode score mean an agent will work in production?

Closer than most benchmarks, but still not a guarantee. FrontierCode already grades against the bar a real merge has to clear, not just whether the tests pass, which is the exact gap Cognition built it to close.

Cognition's own launch post names that gap directly: it calls SWE-bench Verified and SWE-bench Pro "the first generation of coding benchmarks" and says "fundamentally, they only test functional correctness, not quality," citing METR's finding that high-scoring models on those benchmarks "often produce patches that wouldn't be accepted by human maintainers." FrontierCode's criteria, written by the maintainers of the 36 repositories its tasks come from, check scope, style, and project convention alongside correctness, so Cognition says "any PR that satisfies these standards would actually be approved."

What a score still can't tell you is how the agent does outside that snapshot. The tasks and their criteria were fixed and reviewed by a maintainer in advance, [the same advance review a pre-deploy gate gives any change](/answers/deploy-gates/what-cant-a-pre-deploy-ci-gate-catch), and a codebase that has moved on since the task was written isn't the codebase the criteria were written against.
