From the Xiry library · Updated 10 October 2026

Visit docs.x.ai ↗

xAI's developer platform provides API access to Grok models for text generation, reasoning, coding, and multimedia capabilities. It supports OpenAI-compatible SDK integrations, function calling, structured outputs, real-time voice, and image or video generation. Developers can use it to build AI-driven applications with large context windows and integrated live search tools.

What it's for

  • Integrate Grok into web or backend apps using OpenAI-compatible SDKs
  • Run structured data extraction and reasoning tasks with function calling
  • Generate images and videos via programmatic API prompts
  • Build real-time voice agents with speech-to-speech and text-to-speech endpoints

Features

  • Access to Grok text and reasoning models with up to 500k context
  • OpenAI SDK compatibility using custom base URLs
  • Built-in tool calling including web search and X search
  • Structured outputs and JSON schema enforcement
  • Imagine API for image and video generation and editing
  • Voice API supporting speech-to-speech, text-to-speech, and transcription
  • Batch API, async requests, and prompt caching

Pricing

Paid. Pay-as-you-go per token, image, or audio second (e.g. Grok 4.7 at $2/1M input, $6/1M output tokens)
