Grok models (xAI)
Draft · pending editorial review Verified Oct 16, 2026 Review by Nov 15, 2026 1 source
Short answer
Grok is xAI's model family, used in the Grok app and the xAI API. xAI currently recommends Grok 4.7 for both code and chat. It has a 500K-token context window and a May 2026 knowledge cutoff, and it reaches real-time information only when web or X search tools are switched on.
What it is
Grok is the model family from xAI. One general model, Grok 4.7, is the default for text and code. Separate models handle images, video and voice.
How it works
On the API you call a model by name. An unversioned alias tracks the latest stable release, -latest tracks the newest release, and a dated name pins one release. Pricing has two bands: once a prompt reaches 200K tokens, the whole request is billed at the higher rate. Real-time knowledge is opt-in through server-side search tools, including search over X posts.
Benefits
- X search. A direct route to public conversation on X, useful for social listening and news monitoring.
- One default model for chat and code keeps model selection simple.
- Clear long-prompt pricing. You can see where the price step sits and keep prompts under it.
Limits and risks
- No live knowledge by default. Without search tools, answers stop at the training cutoff.
- Long-prompt price step. Prompts at or above 200K tokens double the per-token rate on Grok 4.7.
- Agent connectivity unconfirmed. MCP-client support in the Grok apps is still marked to-verify on our Grok tool page.
