Yep. For the past month I’ve been doing this thing where every time I need something from AI, I give Opus and Codex the same prompt. Opus is just better by a wide margin, especially on complex tasks. It uses tools quite a lot, taps into available MCP servers when it makes sense, and can think about repercussions down the line much better. Codex I feel is optimized for brevity, approaching terseness. Hard to put my finger on it but it’s never as thorough and it always misses important details.
