Cost & Optimization

How to get maximum value from Claude Code while controlling token consumption and costs.

Model Selection Decision Flow

Not all tasks need the most powerful model. Using the right model for the right task cuts costs by 5-10x without sacrificing quality.

This diagram assumes an unconstrained budget (Max/API). On tighter plans (Pro, Teams Standard), apply the budget modifier below.

    B -->|Standard| E["Standard tasks:<br/>feature implementation,<br/>bug fixes, refactoring"]

Budget modifier — On constrained plans, downgrade one tier per phase:

Plan	Planning phase	Implementation phase
Max / API unconstrained	Opus	Sonnet
Pro / Teams Standard	Sonnet	Haiku (mechanical tasks)
API tight budget	Sonnet	Haiku

Community pattern (Teams Standard $25/mo): Sonnet for Plan → Haiku for Implementation. Same quality output on mechanical tasks at a fraction of the cost.

Task complexity?
├─ Simple (typos, format, rename) → Haiku 4.5    ($  — ~5x cheaper)
├─ Standard (features, bugs)      → Sonnet 4.5/4.6 ($$ — balanced)
└─ Complex (architecture, sec.)
   ├─ Needs deep reasoning?        → Opus 4.6      ($$$ — most capable)
   └─ Just large/clear?            → Sonnet 4.6    ($$ — handles it)

Budget modifier (downgrade one tier on constrained plans):
  Max/API    → Opus plan, Sonnet impl
  Pro/Teams  → Sonnet plan, Haiku impl (mechanical tasks)

Cost Optimization Decision Tree

High token costs are usually fixable. This systematic tree identifies the root cause and points to the right fix for each waste pattern.

flowchart TD
    A([High token costs?]) --> B{Context<br/>too large?}
    B -->|Yes| C(Use /compact<br/>or start fresh session)
    C --> Z([Saves 40-60%<br/>per session])

    B -->|No| D{Verbose<br/>responses?}
    D -->|Yes| E(Add CLAUDE.md instruction:<br/>'Be concise, avoid explanations')
    E --> Z2([Saves 20-30%])

    D -->|No| F{Re-explaining<br/>context repeatedly?}
    F -->|Yes| G(Move repeated context<br/>to CLAUDE.md)
    G --> Z3([Saves 15-25%])

    H -->|Yes| I(Use Haiku for simple tasks<br/>See model selection tree)
    I --> Z4([Saves 50-90%<br/>on simple tasks])
