# OpenAI Pricing

> OpenAIs pricing guide details billing for text, image, and audio models, including costs per tokens, images, and audio duration.

  OpenAI’s pricing is dynamic and may change at any time. For the most current rates, please visit [openai.com/pricing][pricing].

OpenAI categorizes its foundation models into three primary types—text, image, and audio—each charged using a distinct unit:

| Model Category  | Billing Unit        | Basis                                           |
| --------------- | ------------------- | ----------------------------------------------- |
| Text            | 1,000 tokens        | \~750 words per 1,000 tokens                    |
| Image           | Per generated image | Cost varies by image resolution                 |
| Audio (Whisper) | Per second of audio | Charged by duration (transcription/translation) |

  A token corresponds to roughly 0.75 English words. Tools like [tiktoken][tiktoken] help estimate token counts before you send requests.

## Text-Based Use Cases

Text models support a variety of tasks, each billed per 1,000 tokens:

| Use Case             | Description                        |
| -------------------- | ---------------------------------- |
| Word/Code Completion | Predictive text or code generation |
| Chat                 | Conversational AI interactions     |
| Embeddings           | Semantic vector generation         |
| Fine-Tuning          | Custom model training              |
