Model Mode
Switch the MODEL_MODE setting in ~/.claude/CLAUDE.md without manual file editing.
Usage
/model-mode status → Show current MODEL_MODE and custom model settings
/model-mode default → Auto-switch: opus for planning, sonnet for coding, haiku for quick
/model-mode opus-only → Always use Claude Opus 4.6 (MAX plan — best quality everywhere)
/model-mode sonnet-only → Always use Claude Sonnet 4.6 (fast + capable)
/model-mode haiku-only → Always use Claude Haiku (fastest, cheapest)
/model-mode custom → Use PLAN_MODEL / CODE_MODEL / QUICK_MODEL from CLAUDE.md
Available Modes
| Mode | Description | Best For |
|------|-------------|----------|
| default | Auto-switches between opus/sonnet/haiku by task type | Most users |
| opus-only | Always uses Claude Opus 4.6 | MAX plan users wanting max quality |
| sonnet-only | Always uses Claude Sonnet 4.6 | Pro plan users, speed + capability |
| haiku-only | Always uses Claude Haiku | Fastest responses, lowest cost |
| custom | Uses PLAN_MODEL / CODE_MODEL / QUICK_MODEL settings | Fine-grained control |
Custom Mode Settings
When MODEL_MODE: custom, these additional settings in ~/.claude/CLAUDE.md control which model is used per task category:
PLAN_MODEL: opus # Used for planning/architecture tasks
CODE_MODEL: sonnet # Used for implementation/coding tasks
QUICK_MODEL: haiku # Used for simple/quick tasks
Instructions
When invoked, perform the following based on $ARGUMENTS:
status or no argument
Read ~/.claude/CLAUDE.md and report:
- Current
MODEL_MODEvalue - If
custom, also showPLAN_MODEL,CODE_MODEL,QUICK_MODELvalues - Example output:
Current model mode: default Auto-switching enabled: opus for planning, sonnet for coding, haiku for quick tasks.
default, opus-only, sonnet-only, haiku-only, custom
- Read
~/.claude/CLAUDE.md - Find the line that starts with
MODEL_MODE: - Replace it with
MODEL_MODE: <new-value> - Write the file back
- Confirm: "Model mode updated to
<new-value>. Changes take effect in the next session."
Invalid argument
If argument is not one of the above values, show usage help and list valid options.
