xAI has released a REST API that is compatible with the OpenAI REST API. This API provides access to various inference capabilities, including responses, chat completions, embeddings, images, videos, voice, files, batches, and models. The API also features the grok-4.6 model.

Key Points

  • The xAI REST API is compatible with the OpenAI REST API.
  • The API reference is generated from an OpenAPI specification.
  • The grok-4.6 model is accessible via the API.
  • API keys are managed through the xAI Console on the API Keys page.
  • Management keys are created on the Management Keys page for access to the Management API.
  • The base URL for inference is https://api.x.ai, requiring Authorization: Bearer <xAI API key>.
  • Collection management and other management functions use https://management-api.x.ai with an xAI Management API key.

Context

According to xAI, the REST API provides developers with tools to integrate xAI's models and services into their applications. The compatibility with the OpenAI REST API aims to simplify adoption for developers already familiar with that ecosystem. The API supports distinct base URLs and authentication methods for inference and management functions, as detailed in the xAI documentation.

Why It Matters

This API release provides developers with a new option for integrating advanced AI models, including grok-4.6, into their projects. The stated compatibility with the OpenAI REST API could reduce the learning curve for developers transitioning between or working with both platforms, potentially broadening the adoption of xAI's offerings.

What To Do

  • Review the xAI REST API reference for specific endpoint details.
  • Create an API key on the API Keys page of the xAI Console to begin using the inference API.
  • For collection management or other administrative tasks, create a Management API key on the Management Keys page.
  • Test the API's compatibility with existing OpenAI REST API integrations.
