Claude Opus drives incident response while GPT Codex needs steering
Original: Claude Opus vs GPT Codex: Who Drives and Who Gets Driven in Real Incident Response
Short summary
A real-world incident comparison shows Claude Opus autonomously diagnosing a Gmail dot-trick login failure across three verification layers, while GPT Codex required human steering three times and stopped at a misleading HTTP 200. The author argues Opus acts as a driver that plans and self-verifies, whereas Codex needs to be driven. Includes a practical checklist for ops teams evaluating AI tools.
- •Claude Opus autonomously traced a Gmail dot-alias issue across database, audit log, and mail provider layers
- •GPT Codex required three human interventions and stopped at a misleading HTTP 200 response
- •Ops teams should test AI tools on real incidents and consider hierarchical driver/worker model setups
