I have a MAX subscription! but why can't I choose to have only opus model in the cloud code????

default is opus and auto switches to sonnet when you run out of "opus quota", which usually is pretty bad.

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

To get started:

* Run claude update
* /model opus

One prompt, and you are done for the week :)

Great news! I just wish Claude has some pro plus tier or something else in between.

November 25, 2025 -

When I try to switch /model
I get this message "Want Opus 4.5? Run /upgrade to get the Max plan or /extra-usage to turn on extra usage"
and only the option to pick from 1. Sonnet and 2. Haiku

Yeah, no Opus 4.5 for Pro users in Claude Code. Also, no changes in limits. I'm disapointed.

Pro user here. I can access Opus 4.5 in the standard Claude (non-code) Web UI, but not in Claude Code CLI. Seems strange, especially as the Opus usage chart has disappeared and been rolled-in to the standard limits according to my Usage page, and others report Opus 4.5 being lighter and cheaper.

Claude Opus 4 With Claude Code: A Developer Walkthrough - The New Stack

May 31, 2025 - Claude Opus 4 has already grabbed quite a bit of attention in the short time it has been public, and in some ways I feel I’m a little slow to the party. I was reading a very detailed breakdown that Federico Viticci did using Claude 4 on the web to sort through his emails. 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.)

Even after updating Claude code I'm still only limited to Sonnet. I'm pretty new at this, so any help would be appreciated.

Opus is only for max plan in claude code. You can use opus in the desktop app though toghether with a file-system mcp.

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.
