Cognition says Devin Fusion scores 68 on coding agent index at 31% lower cost
Cognition says Devin Fusion scored 68 on the Artificial Analysis Coding Agent Index, using Opus 5.5 as lead and GPT-6 Luna as sidekick model, at a 31% lower cost per task than Claude Code with Opus 5.5. Russell Kaplan, the company's president and cofounder, says AI coding has reached a point of "intelligence saturation".
Who is affected and how
- CTO
- When evaluating agents, compare cost per task and the model combination, not just the score.
- tech lead
- Run a pilot on your own codebase, because the vendor's claims rest on an independent benchmark.
