xAI provides a unified API for multimodal AI, offering access to the Grok family of models (including Grok 4.5) that handle text, code, voice, images, and video. The platform is trained on what it claims is the world's largest supercluster and supports over 1 million API calls per day with median latency under 200ms. Developers can integrate via Python, TypeScript, or cURL, and the API is compatible with OpenAI's client library. xAI also offers specialized tools like a CLI for code generation, an image generation API (Imagine), and a voice agent builder.
