What is Grok (xAI)?
Grok is the model family associated with xAI; the current documentation labels its developer SpaceXSI. This profile specifies Grok 4.7, a text-and-image-input model for coding and agentic work. Current-event access requires search tools rather than being an automatic property of the model.
Key features
- Text and image input; text output
- 500K-token context
- Configurable reasoning effort
- Function calling
- Structured outputs
- Optional Web Search and X Search
Best for
- Tool-connected coding assistants
- Search-backed current-event research
- Image-assisted knowledge work
Who it suits
- Developers building search-backed assistants
- Coding-agent teams
- Analysts working with web and X sources
Who may not need it
- Applications requiring offline inference
- Users expecting automatically live answers
Integrations and compatibility
- Web Search
- X Search
Where it fits in a workflow
Use Grok behind an explicit search-and-citation step when freshness matters. Set token and tool budgets separately, and verify retrieved claims before publishing.

Strengths
- Web and X search routes for fresh information
- Reasoning-effort controls
- Structured responses for application pipelines
Watch-outs
- No real-time knowledge without enabled search tools
- Long-context rates apply to the whole request at the threshold
- Search tools introduce charges beyond model tokens
