claude-code - 💡(How to fix) Fix Max subscription: 'Extra usage is required for 1M context' error on default model [1 comments, 2 participants]

On a Max subscription, selecting the default model (Opus 4.6 with 1M context) produces the error:

API Error: Extra usage is required for 1M context · run /extra-usage to enable, or /model to switch to standard context Error message blocks execution, suggesting /extra-usage or /model switch.

TL;DR

Run the /extra-usage command to enable extra usage for the 1M context model, as the error message suggests, despite having a Max subscription.

Guidance

• Verify that the Max subscription is active and up-to-date, as the issue might be related to subscription status.
• Check if there are any specific settings or configurations in the Claude Code application that might be overriding the default model settings for Max subscribers.
• Consider switching to a standard context model using the /model command as a temporary workaround to execute prompts.
• Review the documentation or support resources for Claude Code to see if there are any known issues or limitations with the Opus 4.6 model and Max subscriptions.

Notes

The issue seems to be related to the specific configuration of the Opus 4.6 model with 1M context on Max subscriptions, and running the /extra-usage command might be a necessary step to enable this feature, despite the expectation that it should be included by default.

Recommendation

Apply workaround: Run the /extra-usage command to enable extra usage for the 1M context model, as this is the most direct solution suggested by the error message, and it may be necessary to use the default model with a Max subscription.
