Frequently Asked Questions

diffray FAQ

How does diffray's multi-agent system differ from a single AI model?

A single AI model attempts to be a jack-of-all-trades, often leading to generalized and noisy feedback. Diffray's multi-agent system is a master-of-each approach. It deploys a team of over thirty specialized AI agents, each fine-tuned for a specific task like detecting memory leaks, SQL injection vulnerabilities, or React component anti-patterns.
