# Prompt Enhancement - Overview

> AI-powered prompt optimization tools for better generation results.

<Info>
  In v2 all prompt boosters use a **single unified endpoint** — `POST /api/v2/prompts/enhancements`. You select the booster with the **`type`** field (v2 dot notation) and the target model via **`model_slug`**.

## Workflow

<Steps>
  <Step title="Enhance your prompt">
    Call `POST /api/v2/prompts/enhancements` with `prompt`, `type`, and `model_slug` (plus `image` for `images.edits` / `videos.animations`).
  </Step>

  <Step title="Use the enhanced prompt">
    Plug the returned `prompt` into the matching v2 generation endpoint — `/api/v2/images/generations`, `/api/v2/images/edits`, `/api/v2/videos/generations`, `/api/v2/audio/speech`, etc.
  </Step>
