claude-code - 💡(How to fix) Fix Sonnet 4.6 1M context not exposed in desktop app model picker (Max plan) [1 comments, 2 participants]

TL;DR

The issue can be mitigated by manually setting the model alias per-session via /model sonnet[1m], although a persistent solution is needed.

Guidance

• Verify that the claude-sonnet-4-6 model with 1M context is correctly configured and available on the Max plan.
• Check the desktop app's settings and model picker code to ensure it correctly handles and displays models with context sizes (e.g., "Sonnet 4.6 1M").
• Investigate why setting "model": "sonnet[1m]" in ~/.claude/settings.json is not honored by the desktop app's picker.
• Consider adding a feature request or bug report to the Claude Code issue tracker to address the UI gap.

Example

No code snippet is provided as the issue does not contain sufficient code context.

Notes

The issue appears to be a UI gap rather than an entitlement issue, and the model alias works correctly when set per-session. However, the root cause of the issue is still unclear, and further investigation is needed.

Recommendation

Apply workaround: use the per-session /model sonnet[1m] command until a persistent solution is available, as it is the only known method to access the "Sonnet 4.6 1M" model.
