What's Wrong?

Title: Opus 4.6 permanently rate limited on Pro subscription - 5 days and counting

Claude Code version: 2.1.87

Platform: Windows 11

Description:
For the past 5 days I have been unable to use Claude Opus 4.6 in Claude Code from terminal. Every request returns "API Error: Rate
limit reached" immediately. Sonnet 4.6 works fine in the same session. The usage meter shows significant weekly budget
remaining. I can also use opus 4.6 from console, but when i try using it in terminal it gives me the error.

Expected behavior:
Opus 4.6 should be available on a Pro subscription. Sonnet 4.6 works without issue.

What I've tried:

• Restarting Claude Code
• Waiting multiple days (5 days total, no recovery)
• Confirmed Sonnet 4.6 works normally
• Confirmed Opus works in claude.ai web console

Notes:
The issue appears to be Opus-specific and persistent, not a temporary burst limit. Weekly reset (Monday) did not
restore access.

What Should Happen?

I should be able to use opus 4.6 in my terminal as before I did.

Additional Information

I downgraded my plan from max to pro a week ago. This started to happen after that. But its still strange as I did almost nothing that week and I can not use opus from terminal. Many of my tools use opus from terminal and thus are not usable anymore for me. This is critical issue for me.
