What's Wrong?

I'm a Pro plan subscriber and Claude Code has become completely unusable due to a bug introduced in a recent update.

Issue:
Every request in Claude Code is being routed to the 1M context tier, triggering the error: "API Error: Usage credits required for 1M context". This happens immediately on fresh sessions with zero context accumulated. My current usage is only 12-15% of my plan limits, so this is not a usage limit issue — it is a routing bug.

Environment:

• Plan: Pro
• Model: claude-sonnet-4-6 (default)
• Platform: macOS
• Claude Code Desktop UI

Workarounds attempted:

• Enabling usage credits with $0 spend cap — did not resolve the issue
• CLAUDE_CODE_DISABLE_1M_CONTEXT=1 environment variable — did not resolve

This is a known bug filed across multiple GitHub issues:

• github.com/anthropics/claude-code/issues/62063
• github.com/anthropics/claude-code/issues/62199
• github.com/anthropics/claude-code/issues/64349

The change was made without any notification to Pro users, and standard workarounds are not working.

Request:
Please provide either (1) a fix or patch version that resolves this, or (2) a credit to my account for the period Claude Code has been unusable, as I am paying for a Pro subscription I cannot use.

Thank you.

What Should Happen?

Claude should allow me to continue use without this blocking error - i am well within my utilisation limits
