  title: AI Studio System Prompts API
  version: '0.1'
  description: 'The AI Studio API is a REST API for the full lifecycle of custom AI models on Hyperstack AI Studio: curate and generate training datasets, fine-tune foundation models on your data, evaluate training results, deploy models, and run inference. Inference runs on base and fine-tuned models, covering text chat (OpenAI-compatible chat completions) and image generation and editing.


    ## Base URL


    All requests are sent to:


    ```

    https://console.hyperstack.cloud/ai/api/v1

    ```


    ## Authentication


    Every request requires an API key. Pass it as the `api_key` request header, with the raw key as the value and no prefix (`api_key: YOUR_API_KEY`). Generate a key on the [API Keys](https://console.hyperstack.cloud/api-keys) page in the Hyperstack console. See [Getting Started with the API](https://docs.hyperstack.cloud/docs/ai-studio/getting-started#getting-started-with-the-api) for the full walkthrough.


    ## Request and response format


    Requests use standard HTTP methods (`GET`, `POST`, `PUT`, `PATCH`, `DELETE`) with `application/json` bodies unless noted otherwise. Responses are `application/json`. The text inference endpoints, such as [chat completions](https://docs.hyperstack.cloud/docs/ai-studio-api-reference/chat-completions), are OpenAI-compatible.'
