Codex (OpenAI) vs Devin

Codex (OpenAI) edges out Devin by 0.9 points (8.3 vs 7.4) -- a A-tier vs B-tier split that's narrow but real. Not a blowout; both belong on a shortlist. The score gap shows up most clearly in the categories that matter for Codex (OpenAI)'s strengths, so if those categories are your priority, the lead translates.

On pricing, Codex (OpenAI) starts free while Devin requires a paid plan from day one ($20+). If you're testing the waters or running an occasional workload, that gap matters more than the score differential. Codex (OpenAI) starts at $0; Devin starts at $20. Compare what each entry tier actually unlocks before you compare list prices -- the limits matter more than the headline number.

By use case: pick Codex (OpenAI) when developers already paying for chatgpt plus who want a coding agent at no extra cost. Pick Devin when development teams that want to offload well-scoped tasks like bug fixes, test writing, and boilerplate code to an autonomous agent. The two tools aren't fighting for the same person -- they're aiming at adjacent jobs that occasionally overlap. If you're squarely in Codex (OpenAI)'s lane, the tier-list ranking and the use-case fit point the same direction; if you're in Devin's lane, the score gap matters less than the fit.

Bottom line: Codex (OpenAI) is the safer default for most readers, but Devin is competitive enough that the tie-breaker is your specific workload, not the spec sheet.
