# GPT-5.4 API

GPT-5.4 by OpenAI on one AI Creator API key, in Cline, OpenCode and Aider. You pay for the actual tokens; the balance is in dollars, topped up by card or crypto.

## Price per 1M tokens

Prices as of November 11, 2026

| Tokens                 | AI Creator API |
| ---------------------- | -------------- |
| Input                  | $0.085         |
| Cache read             | $0.009         |
| Cache write, 5 minutes | $0.106         |
| Cache write, 1 hour    | $0.17          |
| Output                 | $0.509         |

- A dash means the model has no such price. Cache reads and writes are counted apart from input: a token lands in one counter only.
- Every model and its prices are on the [pricing page](https://llm.aicreator.app/en/pricing/).
