xAI Grok
Grok model family with real-time search through one API
xAI Grok is profiled here as a LLM tool for engineering teams. Read about features, pricing, and how it compares to related options in the tools directory.
Description
Grok is the family of large language models from xAI, the company Elon Musk founded in 2023. The Grok API exposes the latest models with large context windows and built-in tools for web and X search, and it stays compatible with the OpenAI and Anthropic SDKs so teams can migrate by changing a base URL and key. xAI offers promotional credits to new developers, and Grok models add native tool calling and reasoning modes for agentic workloads.
Key Capabilities:
Access to current Grok models through an OpenAI- and Anthropic-compatible API
Large context windows that handle long documents and multi-step orchestration
Built-in web search and X search tools invoked inside the model's reasoning
Native tool calling and parallel function calls for agent workflows
Configurable reasoning effort that trades depth for token cost
Vision support for image understanding alongside text
