alt Hacker NewsSlightly ot but I've been using OpenAI's GPT 5.4 on Codex and so far finding it more convincing than Claude with Opus 4.6 at maximum thinking for my use cases.
I'm more interested in helping with design and architecture rather than having it author tons of code.
Keep in mind that OpenAI has a way more generous tier for 20$ than Anthropic's one, and I think you can even use codex for free with the latest models, so give it a shot, you may find it better than you expected and a solid backup to Claude.
I agree it seems better at complex work. However, I find that it often tries to make ALL work complex. I had a simple bug fix where I knew exactly what the 1-2 line fix was. GPT 5.4 added like 200 LOC and started refactoring the entire function of the app. Was the refactor possibly an improvement? Maybe, but I needed the fix quick so I stopped it and switched to Claude, which did exactly what I was expecting.
