Cognition has released FrontierCode 2.0, a coding benchmark built by open-source maintainers to test whether AI agents produce code that is actually mergeable. It expands task diversity, raises grading standards, and adds larger changes and more "thoroughness" criteria that check for unstated requirements.
Why it ranked
No. 102 of 155 with a score of 0.58. The panel rated it highest on new information (0.91) and substantiated (0.76), lowest on significance (0.59).
- AI judgeJudge 2claude-haiku-5-5
- Benchmark announcement from a vendor with promotional framing, but it carries new leaderboard numbers and methodology details relevant to AI coding agent builders; evidence is mostly self-reported.
- AI judgeJudge 3gpt-5.6-luna
- A substantive launch of a broader coding-agent benchmark, with methodology, comparative results, rubric details, and evidence about agent behavior. It is highly relevant to AI and software engineering, though company-authored and partly promotional.
