Documentation

Everything you need to plug CheapAI into your tooling — setup guides for popular agents, API reference, FAQ.

  • Compact your history

    Long context is expensive. Run /compact in Claude Code to compress the history — especially before switching tasks.

  • One key per project

    Create a separate key for each project — easier spend tracking and a quick revoke if one leaks.

  • Watch your spend

    The Logs page shows every request — model, tokens, cost, duration.

  • Pick the right model

    Haiku / Flash — light mechanical work and bots. Sonnet — workhorse for agents. Opus — heavy reasoning when quality matters.

  • Use the cache

    System prompts and stable documentation are cached automatically by Anthropic. A long session with one prompt saves 70-90%.

  • /cost ≠ actual spend

    Claude Code's built-in /cost uses Anthropic's official pricing — we're 30-40× cheaper. Look at Logs for the truth.
