The mode claude-sonnet-4 does not work with your current plan

That’s quite strange. Have you tried starting a new chat and restarting Cursor?

Ah, starting a new chat did the trick! (Restarting Cursor alone didn’t help).

Thanks @deanrie :+1:

Yeah this is resolved :slight_smile:

If anyone still has an issue, please look at possible solutions here, like starting new chat.

I’m still encoutering that issue, at least for all the new models. What model id do you use for Sonet 4 and Opus 4?

claude-4-sonnet and claude-4-sonnet-thinking are the models in cursor settings.

Did you restart Cursor and started a new chat?

All of a sudden this appears again. Worked the whole day until now

Hello,
I don’t understand, as a Free user of Cursor with my Anthropic API key, I cannot use Claude 4 (sonnet or opus)?

I have tried two things:

  • Directly use the model claude-4-sonnet displayed in the Cursor settings and I get this message:

Anthropic’s latest models are currently only available to paid users. Please upgrade to a paid plan to use these models.

What did I do wrong?

Thanks in advance!

Hey, do you have a Pro subscription?

Hello Deanrie,

No, I don’t have a Pro subscription to Cursor. I specifically want to use only my Anthropic API with the claude-sonnet-4-20250514 version of their API.

Im having the same issue but with all models using an openrouter api key.

same problem here

i would not advise max or api usage mode unless you want to spend 50 dollars in an hour. they have done something irresponsible in implementation.

Same here. Paying for Cursor pro version solely to use it with Claude 4 Opus, which is not available. So a waste of money, with zero customer support and no refund.

same here, free plan, claude 3.7 works fine with api
with pro requirement they must’ve screwed up the api usage

Hey all, it seems likely that we have to make some minor changes to ensure your keys are working correctly with Claude 4!

I’ll pass this to the team and get back to you all soon.

What hoppen? How to fix it?

With API key or with Pro, both are broken right now and nothing shows up on the status page. Windsurf with the same model is working fine


:confused:

Pro user here. I get a slightly different error saying ‘The mode claude-sonnet-4-thinking does not work with your current plan’, even though I have selected the non-thinking sonnet 4 model. It was working perfectly until I started a new chat, and all of a sudden this error starts throwing up!

Tried restarting cursor, developer window, deleting previous chats, and opening up new chat - no luck!

Same issue on sonnet 4 thinking model


I’m pro user
is sonnet 4 thinking model now only with api or max mode?
