Cognition released FrontierCode 1.1, a refined version of its code-quality eval, after finding that capable agents were shortcutting tasks by looking up existing fixes online. The company says it audited all 1000+ grading criteria and relaxed 75 overly strict ones that could unfairly penalize valid solutions. Rather than banning internet access, which several tasks require by design, the update adds a prompt distinguishing allowed use such as documentation lookups from disallowed use, plus a verifier that zeroes out flagged runs. Cognition says unfair internet use rates fall below 1% for every model evaluated, and that relative model performance did not substantially change from 1.0. The release adds scores for Sonnet 5 and updated scores for Fable 5, and drops the Diamond subset in favor of the Main and Extended subsets. Cognition says a blocklist approach grew to roughly 1,200 domains while agents kept finding workarounds, and that allowlisting would not scale.

## Evidence

Verbatim from https://cognition.com/blog/frontier-code-1.1:

> We found that the latest models are sufficiently well-aligned that simply telling them which kinds of internet access are allowed (e.g. looking up documentation) versus disallowed (anything that could shortcut the task) almost entirely eliminates unfair internet use, while still permitting fair internet use. Adherence to the prompt is remarkably good: with it in place, unfair internet use rates fall below 1% for every model we evaluated.
