I’ve been switching back and forth between Opus and GPT-5.5 lately, mostly for coding, debugging and product/spec writing.
My rough feeling so far:
GPT-5.5 feels better as a daily “get things done” model. It’s fast enough, usually smart enough, and feels more cost-effective for normal builder work.
Opus still feels stronger when I’m stuck on something messy, like architecture decisions, weird bugs, or when I want a second opinion that thinks a bit differently.
A few people around me have also started using GPT-5.5 more often, but I’m not sure if that’s just hype / novelty bias.
Curious what people here are actually using:
- What’s your default model right now?
- Is Opus still worth the extra cost for you?
- For coding specifically, which model helps you ship faster?
- Do you use one model for daily work and another for harder reasoning?
