I’d say GPT-5 is the best in following and remembering instructions. After an initial plan it can easily continue with said plan for the next 30-60 minutes without human intervention, and come back with a complete working finished feature/product.

It’s honestly crazy how good it is, coming from Claude. I never thought I could already pass something a design doc and have it one-shot the entire thing with such level of accuracy. Even with Opus, I always need to either steer it, or fix the stuff it forgot by hand / have another phase afterwards to get it from 90% to 100%.

Yes the Codex TUI sucks but the model with high reasoning is an absolute beast, and convinced me to switch from Claude Max to ChatGPT Pro
