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 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.

October 2, 2025 - Claude 4.1 Opus came out swinging with energy. The opening line—”Let’s talk real talk: You’re not getting replaced by AI”—hits hard and immediately establishes a conversational vibe. It leaned heavily into metaphors (the orchestra conductor theme) and maintained a consistently upbeat, almost motivational speaker energy throughout. Claude 4.5 Sonnet opened with: “Here’s the truth nobody’s saying out loud: Your job isn’t one thing—it’s fifty things wrapped in a fancy title.” Different approach, but equally engaging.

r/ClaudeAI on Reddit: Claude Code Opus vs Sonnet

June 20, 2025 -

I heard people prefer Opus over Sonnet in Claude Code, is this true? I’ve been using Sonnet for the past two weeks and it works great, but gets things wrong sometimes? Is Opus any better?

Yeah, consistently better on harder tasks and recovering from errors, just get the 20x max, absurd value for money

Opus is great but not at everything. It's often good when Sonnet gets stuck, it's good for planning, but I personally find Opus can sometimes overthink and/or overengineer a task while Sonnet tends to be more direct. I use Opus only when Sonnet gets stuck or consistently goes in the wrong direction with something, or when I need a plan. Not to mention Sonnet responds faster.
