Cognition describes how it has begun deploying multi-agent systems that work in practice, focusing on patterns where multiple agents contribute intelligence while writes stay single-threaded. The company reports that its Devin Review catches an average of 2 bugs per pull request, with roughly 58% being severe, and that Devin and Devin Review now natively iterate against each other so most bugs are resolved before a human opens the PR.

## Evidence

Verbatim from https://cognition.com/blog/multi-agents-working:

> At Cognition, we've begun to deploy multi-agent systems that actually work in practice. ... Devin Review catches an average of 2 bugs per PR, of which roughly 58% are severe (logic errors, missing edge cases, security vulnerabilities). ... Today, we make Devin and Devin Review natively iterate against one another, so that most bugs are already resolved by the time a human opens the PR.
