yiwei-1 Got a similar response when using the API directly (but not through the Claude web app). We'll review the system prompt and see if we can fix the issue there.
WhatMatters Actually, it even says "Claude 3.7 Sonnet" inside a conversation. Even though it's set to Opus 4 in the custom settings.
