Opus follows instructions better than sonnet for big tasks, but it can sometimes overthink or overengineer something. Sonnet tends to be more direct but can sometimes not follow instructions as good as opus. I'd say opus is great at planning and executing big tasks, while sonnet is best for simpler tasks that dont need the intelligence of opus.or at least plan with opus, code with sonnet, is another way.

r/ClaudeAI on Reddit: Are you seeing big difference between Sonnet vs. Opus?

June 22, 2025 -

I’m on the $100/month plan. 1-2 prompts in I got my limit on Opus, then I spend most of my coding day on Sonnet.

Whenever I am on Opus, it isn’t obvious it’s writing code that Sonnet can’t. I see a bigger difference between prompts that do vs. do not have “ultrathink” rather than Sonnet/Opus.

Does anyone with more experience have a clear perspective on Sonnet vs Opus? Even on the benchmarks they are about the same.

Opus follows instructions better than sonnet for big tasks, but it can sometimes overthink or overengineer something. Sonnet tends to be more direct but can sometimes not follow instructions as good as opus. I'd say opus is great at planning and executing big tasks, while sonnet is best for simpler tasks that dont need the intelligence of opus.or at least plan with opus, code with sonnet, is another way.

Opus is absolutely worth it for me and a large codebase at least. It's not just the line of code being different, it's the entire logic process. Basically, it's much more efficient which saves me time.
