# LLM Pricing

> Pricing rules for OpenAI, Claude, Grok, and Gemini models on TTAPI

<Callout type="info">
  LLM billing follows the vendor's input and output pricing model, then applies the TTAPI channel discount where applicable. Supported models change over time, so this page focuses on the main platforms and pricing rules rather than every single version.

## Notes

If a platform offers multiple versions of the same model family, the same discount rule usually applies across that platform unless TTAPI announces a special promotion or a separate pricing exception.

Final cost per request still depends on actual input tokens, output tokens, context size, and model version.
