CLI /model picker doesn't list Sonnet 5 as a preset; shows custom model instead

[palminha]

Preflight Checklist

• I have searched existing issues and this hasn't been reported yet (closest related: Opus 4.8 not selectable in CLI /model despite being available on account #63456, [BUG] Sonnet 5 or Sonnet 4.6? #72584 — neither is an exact match)
• This is a single bug report
• I am using the latest version of Claude Code

What's Wrong?

The /model interactive picker in the terminal CLI does not list Claude Sonnet 5 (claude-sonnet-5) as a named preset option, unlike the VSCode extension, which already shows "Sonnet 5" as a proper labeled entry with pricing info in its model picker.

Setting the model manually via claude --model claude-sonnet-5 (or /model followed by typing the model ID) works correctly — the CLI accepts it and confirms with "Kept model as claude-sonnet-5". However, afterward the /model picker/status UI displays it generically as "custom model" instead of showing it as "Sonnet 5" with its description/pricing, the way Opus, Sonnet 4.6, Haiku, and Fable presets are shown.

What Should Happen?

The CLI's /model picker should include Sonnet 5 as a first-class named preset (with description and pricing, e.g. "Sonnet 5 · Efficient for routine tasks · $2/$10 per Mtok · promo through Aug 31"), matching what's already shown in the VSCode extension's picker, instead of falling back to a generic "custom model" label.

Steps to Reproduce

1. Update Claude Code CLI to the latest version
2. Run claude --model claude-sonnet-5 or set it via /model
3. Run /model again to view the picker/current selection
4. Observe the model is labeled "custom model" rather than "Sonnet 5"
5. Compare with the VSCode Claude Code extension's model picker, which already lists "Sonnet 5" as a proper named preset

Claude Code Version

2.1.185

Platform

Anthropic API

Operating System

macOS (Darwin 25.5.0)

Terminal/Shell

zsh

Is this a regression?

No — this is a new model (Sonnet 5) not yet added to the CLI's preset list, while it has already been added to the VSCode extension's preset list.

Additional Diagnostic Info

Installation method: Homebrew Cask (brew install --cask claude-code)

• Installed: /opt/homebrew/Caskroom/claude-code/2.1.185
• claude update reports already on latest version

Context window regression (related symptom): When claude-sonnet-5 is active as "custom model",
the CLI status bar reports 200k context window instead of the correct 1M. This was also observed
in #63456 for Opus 4.8 when shown as "custom model".

VSCode extension behavior: The VSCode Claude Code extension (same account, same day) already
lists "Sonnet 5" as a named preset with pricing ("Sonnet 5 · $3/$15 → $2/$10 per Mtok · promo
through Aug 31"), confirming the model is available to the account — it's purely a CLI preset
list gap.

Note for Anthropic team: Unlike #63456 (Opus 4.8, fixed by updating CLI), this issue persists
on the latest CLI version (2.1.185). Sonnet 5 appears not yet been added to the CLI's hardcoded
preset list, while the VSCode extension already has it.

@claude review my last input

[palminha]

i can see the release notes claiming about sonnet 5, but the /model command still doesn't show them

[palminha]

The release notes make it clear — it seems i need version 2.1.197 to get Sonnet 5 in the picker, but your brew cask is still on 2.1.185. The cask hasn't been updated yet.

The cask is the problem — Homebrew's cask registry hasn't been updated to 2.1.197 yet, so it still thinks 2.1.185 is the latest.

[palminha]

The difference between the two casks:

• claude-code — stable/slower channel, currently stuck at 2.1.185
• claude-code@latest — fast channel, already at 2.1.197 with Sonnet 5

Same pattern, now with Claude Opus 5 on the latest CLI version.

Environment:

• Claude Code: 2.1.229 (latest on npm)
• OS: Windows 11
• Shell: PowerShell / Git Bash

Behavior:
The /model picker still lists "Opus" as a preset pointing to Opus 4.8, not Opus 5. claude-opus-5 is only reachable by typing the model ID directly, after which it appears as "Custom model" in the picker.

4. Opus    Opus 4.8 · Best for everyday, complex tasks · ~2× usage vs Sonnet
6. claude-opus-5 ✔   Custom model

Unlike the Sonnet 5 case in this thread (which was a Homebrew cask version lag), this persists on the latest npm release — the CLI preset list for "Opus" hasn't been updated to point to claude-opus-5.

Workaround: /model claude-opus-5 sets it correctly; it just shows as "Custom model" rather than a named preset.
