I have a max five subscription, and I have the same exact option. I saw somewhere else people having the choice between opus and sonnet. Not sure why we have this simplified option

Claude Opus 4 With Claude Code: A Developer Walkthrough - The New Stack
May 31, 2025 - I know he likes detail, but I was slightly worried about the 200-line prompt file he was maintaining. (I later understood that Claude writes a lot of notes into its own file.) I was looking to use Claude Opus 4 with Claude Code (which I tried out last month) and had a specific idea of what I wanted to apply its agentic abilities to.

How to use Claude 4.5 Opus with Cursor and Claude Code
1 month ago - By using Claude Opus 4.5, both Cursor and Claude Code can benefit from its deeper reasoning and memory — but which tool you choose depends on your workflow preferences. Switch models thoughtfully — Because Opus is powerful but more expensive, switch only when you need its reasoning strengths. Use planning mode in Claude Code — Have the agent plan out multi-step tasks before executing.

Do you have option to choose Opus in claude code? I see only Default and Sonnet 4 to choose from in /model
Top answer 1 of 2

you don't want to go for opus. Mine used opus as a default after update. Then what usually last me 5 hours was used up in an hour. It secretly switched to sonnet even earlier than that and that's ok. but i now have 3.5 hours to wait. I need to know how to specify how to use sonnet only once my limit resets.

I wonder why my Usage page on my Pro account says the following and yet I can't switch to the model: Updates to usage limits: November 24, 2025 We've removed the Opus cap so you can use Opus 4.5 up to your overall limit. You can also now purchase extra usage for access to Opus 4.5 in Claude Code. We may continue to adjust limits as we learn how usage patterns evolve over time.
