[Bug] Opus 4.5 missing from Claude Code model picker menu
Bug Description
Bug Report: Opus 4.5 Missing from Claude Code Model Picker
Summary
Claude Opus 4.5 does not appear in the /model menu for Max plan subscribers in Claude Code CLI, despite being accessible when specified explicitly.
Environment
Claude Code version: 2.0.37
Subscription: Max plan
Steps to Reproduce
Launch Claude Code CLI with an active Max subscription
Run /model to open the model picker
Observe available options
Expected Behavior
Opus 4.5 should appear as a selectable option in the model picker menu, similar to how it appears in the web and desktop apps.
Actual Behavior
The model picker shows:
- Default (recommended) Sonnet 4.5 · Smartest model for daily use
- Opus Legacy: Opus 4.1 · Reaches usage limits faster
- Haiku Haiku 4.5 · Fastest model for simple tasks
Opus 4.5 is missing. The Opus option still references Opus 4.1 as Legacy.
Workaround
Opus 4.5 IS accessible by specifying the model string directly:
/model claude-opus-4-5-20251101
This succeeds with: Set model to claude-opus-4-5-20251101
Impact
Users may not realize Opus 4.5 is available to them
Inconsistent experience between web/desktop apps (where Opus 4.5 is visible) and CLI
Menu labels are misleading (Opus 4.1 labeled as the Opus option when 4.5 exists)
Suggested Fix
Update the model picker menu to include Opus 4.5 as an option for Max plan subscribers, or replace the Opus 4.1 entry with 4.5.

Same issue here. It's available in CLI version, but not in the VS Code version. However, it was until a few days ago. Unsure if this is related to the latest release? (2.0.58)

Same thing happened to me today. Yesterday everything worked just fine but now it dissapeard.
Same here. VS Code is not showing Opus 4.5 despite its available per CLI. Other instances on other PCs of mine do not have the problem with the VS Code extension. There it sets the default correctly to Opus 4.5.
Confirming this issue on Arch Linux (AUR package
claude-codeversion 2.0.62-1).Reproduction:
/model opussets model to Opus 4.1 (claude-opus-4-1-20250805)opusalias should map to Opus 4.5 as per the documentationWorkaround:
Using the full model ID works:
/model claude-opus-4-5-20251101The model alias mapping appears to be outdated and needs to be updated to point to Opus 4.5.
