Claude Desktop Removes Opus 4.6 Model

·2026.04.18 01:57

Key point

The Opus 4.6 model has been removed from Claude Desktop's Code tab, raising concerns about increased token consumption.

Details

In Claude Desktop (macOS)'s Code tab, following the release of Opus 4.7, the existing Opus 4.6 model has been removed from the selection options. Currently, only Opus 4.7 is available in this tab, with no way to pin or select a model.

This change can directly affect users' token usage. Opus 4.7's new tokenizer is known to generate approximately 35% more tokens for the same input, meaning users with limited message or token quotas will exhaust their quotas much faster than before.

Currently, Claude.ai web chat and Cowork still allow selection among multiple models, but in the desktop app's Code tab, model switching or fallback via the /model command supported in the CLI is not possible.
