Not really, GPT 5.4 is a great alternative. There's no real loss from using that over Claude Opus. And open models are quite close behind.
I’ll try 5.4 again but when I spent a couple of hours with it, I found it much weaker than Claude code + opus 4.6 for working on large projects.
Are you delegating substantial work like planning and executing refactors, or more at single-line and function-level work?
GPT 5.4 keeps erroring out when I’ve tried it on long complex tasks. Might be works harness I guess.
I'll do most of my work in opencode with GPT 5.3/5.4 and just spin up Claude Code for a review/cleanup pass.
Opencode just works faster and I prefer the UX.
