TL;DR

Turn off the Extra Usage toggle in Settings > Usage to prevent further extra charges and file a support ticket referencing the known GitHub issues.

Guidance

• Immediately turn off the Extra Usage toggle in Settings > Usage to stop incurring extra charges.
• File a support ticket referencing GitHub issues #28927 and #29289 to potentially receive a refund for the extra charges.
• Verify if your Claude Code is running with the 1M context window, as this is likely triggering the extra charges.
• Check the error messages in the provided JSON output to confirm that the "Extra usage is required for 1M context" error is related to the billing issue.

Example

No code snippet is provided as the issue is related to billing and configuration rather than code.
