New: every message picks a fast or a slow model

Grok

Grok is xAI's API platform for text, image, video, embedding, file, search, and voice capabilities.

What agents can do

Actions8

  • Create embeddings

    Create vector embeddings for one or more text inputs with an xAI embedding model.

  • Create response

    Generate a bounded, non-streaming Grok response from text or structured multimodal input, with optional reasoning, search, and function or web-search tools.

  • Generate image

    Generate one or more images from a text prompt with an xAI image-generation model.

  • Generate video

    Start asynchronous xAI video generation from a text prompt, optionally conditioned on an image, and return a request ID for status checks.

  • Get api key info

    Inspect the connected xAI API key's identity, wildcard or granular ACLs, and key or team blocking state.

  • Get current account

    Verify the connected xAI credential and return the caller, team, zero-data-retention status, and key blocking state.

  • Get video

    Check an asynchronous xAI video request.

  • List models

    List models available to the connected xAI key, including model IDs and published pricing metadata needed to choose a model for other tools.

How it connects

You paste an API key from Grok on a page Composio hosts, so the key never passes through Definable.

Keep the connection to yourself or share it with your workspace. Any action that writes or sends can wait for your approval.
