# Text To Text

Billing for text-to-text language models on Distribute.ai is based on a fixed rate per token, ensuring transparent and usage-based pricing. Each request incurs charges for both input and output tokens. **Input tokens** are the pieces of text you send into the model—this includes your prompt, instructions, or conversation history. **Output tokens** are the text generated in response by the model. A "token" can be as short as one character or as long as a word . Users are only charged for what they use, and rates are clearly defined for both input and output to help estimate costs before making a request.

| Model         | Input Token Cost | Output Token Cost |
| ------------- | ---------------- | ----------------- |
| Llama-3.1 8B  | $0.1 / 1M Tokens | $0.16 / 1M Tokens |
| Llama-3.3 70B | $0.7 / 1M Tokens | $0.8 / 1M Tokens  |
