[Bug] API Error: Usage credits required for 1M context with standard model selected

Bug Description
Claude Code keeps triggering “API Error: Usage credits required for 1M context” even when standard context is selected. Version: 2.1.121 Earlier version tested: 2.1.159 I already tried: - /model and selected standard/default Sonnet - CLAUDE_CODE_DISABLE_1M_CONTEXT=1 - ~/.claude/settings.json env config - full Claude Code restart - fresh session without resume - downgrade from 2.1.159 to 2.1.121 The 1M context option is not visible in /model, but the API still triggers 1M context. Please check if this is an account-side or Claude Code bug.
