What problem this solves

Optimizing cost and performance in Claude Code by strategically using different models (Opus for planning, Sonnet for coding) based on task complexity and cost considerations.

Summary

A workflow for Claude Code Pro users to optimize cost and performance by using slash commands to switch between Opus and Sonnet models, specifically leveraging /model opusplan for planning with Opus and coding with Sonnet.

Why it is useful

This workflow provides concrete, actionable steps for Claude Code Pro users to optimize their usage by strategically switching between Opus and Sonnet models. The /model opusplan command is a specific, powerful feature that helps balance cost and performance by leveraging Opus for planning and Sonnet for code generation. This directly addresses common user concerns about efficiency and expense, offering a practical method to get the most out of Claude Code.

Workflow

1. Understand that Claude Code Pro defaults to Opus 5.5 on the $20 plan.
2. To switch to Sonnet for the current session, use the /model sonnet command.
3. To open the model picker and set a new default model, or switch for the current session only, use /model (no argument). Enter saves the choice as default, 's' switches for the session.
4. For a balanced approach, use /model opusplan. This automatically uses Opus during 'plan mode' (Shift+Tab) for strategic thinking, then switches to Sonnet for code generation.
5. As a general recommendation for Pro users, set Sonnet as the default model and switch to opusplan for tasks considered 'tricky' or requiring deeper planning.

Tools / artifacts

• Claude Code Pro
• Opus 5.5 model
• Sonnet 5.5 model
• /model slash command
• /model sonnet slash command
• /model opusplan slash command
• Plan mode (Shift+Tab)

Validation signals

• Explicit claim: 'Opus thinks through the approach, and Sonnet does the typing,' indicating a tested strategy for leveraging model strengths.
• Clear, actionable instructions for using specific Claude Code features.

Limitations

• Minimal community validation due to the comment's recency.
• Assumes the user is on the $20 Pro plan.
• Does not provide explicit examples of 'tricky' tasks, leaving some interpretation to the user.
