Authentication Error: Claude Pro Users Unable to Access Opus 4

Can you try logging in again? /logout -> /login. Claude Code does not automatically pick up your subscription plan.

I am experiencing the same issue now, but as a Pro user and I'm not sure if it's intended or not, from what I'm able to find the documentation on Claude Code doesn't provide satisfying information on which models are supposed to be available on the different subscription plans.However I did restart my Claude subscription earlier today (after having been expired for a couple of days).

I'm running Claude Code 1.0.31 on Linux.

I'm quite sure I was able to use Opus 4 + Claude Code with my pro plan before though? Has it been restricted to be available only for Max users lately?

I am also experiencing this issue.

Using CC in vscode on debian

Logging out and logging back in with account did not fix this. However, if I login with API I can choose Opus, but I should get access via my Pro plan.

Claude Pro users do not have access to Opus in Claude Code. (See the pricing section of https://www.anthropic.com/claude-code).

The original issue here was for a user with a Claude Max subscription. Closing this issue but will still await a response from @ArturoTorresMartinez if more troubleshooting is needed.

I'm having the same issue as Arturo - I pay $200 for Max, but I'm getting "Claude Pro users are not currently able to use Opus 4 in Claude Code. The current model is now Sonnet 4."

I've tried logging out then in and a few variations.
Up to date.

Hi man, does uninstalling and reinstalling work? That's what did it for me, not the log out/ log in

Hey I found a fix that worked for me! Log out of Claude Code. Then go into your Claude settings on the Claude website, go to Claude Code, delete the authentication token.

Now go back to your terminal, and do /login with claude code, follow the instructions, and that fixed it for me. Do /status when you get back in and hopefully it says Max...

@dicksontsai using CLAUDE_CODE_OAUTH_TOKEN to authenticate limits model choice to Sonnet on a Max plan.

Cross-posting from anthropics/claude-code-action#236:

$ claude -p 'what model are you'
I'm Claude, powered by the model Opus 4 (claude-opus-4-20250514).

$ export CLAUDE_CODE_OAUTH_TOKEN

$ claude -p 'what model are you'
I'm Claude Sonnet 4 (model ID: claude-sonnet-4-20250514).
