xAI
xAI is an artificial intelligence company focused on developing the Grok family of large language models and multimodal AI systems. Founded by Elon Musk, the company positions Grok as a “maximally truth-seeking” AI assistant designed to provide direct, insightful, and real-time responses. xAI places strong emphasis on reasoning, large-context processing, web-connected generation, and agentic tool usage, while integrating its models across the broader X ecosystem and developer platforms.
The currently supported model families include:
Grok flagship models — xAI’s primary reasoning and multimodal models intended for production AI workloads. The Grok lineup includes:
High-performance reasoning models optimized for coding, analytical workflows, and advanced instruction following.
Fast non-reasoning variants designed for low-latency conversational and agentic applications.
Vision-capable Grok models supporting image understanding and multimodal interaction. Recent Grok generations also introduce extended context windows, native tool calling, structured outputs, search integration, and real-time external information retrieval capabilities.
All xAI models in this provider are accessed through the standard /v1/chat/completions endpoint, providing a unified OpenAI-compatible integration layer across the entire model catalog.
Supported capabilities vary depending on the specific model, with different models offering different combinations of the features listed below.
Text completions: Build conversational systems and advanced text-processing pipelines.
Function Calling: Utilize tools, APIs, and structured workflows.
Stream mode: Receive partial responses incrementally as tokens are generated.
Vision Tasks: Process and analyze images and visual inputs.
Reasoning Tasks: Execute advanced analytical, coding, and multi-step reasoning workflows.
Large Context Processing: Work with extremely large prompts, documents, and conversational histories.
Other model categories from this provider are available as well.
