Grok 4.7 is a Frontier-tier AI model developed by xAI, which now operates under the SpaceXAI name, and released in September 2026. It is a proprietary closed-weight model, available through the Grok API, Grok Build, Cursor, and other third-party tools and platforms. The 500K-token context window is large enough to hold sizeable codebases and lengthy technical documents.

Grok 4.7 was released on September 21, 2026 and replaces Grok 4.6. It uses a new, larger base model and was trained with a longer reinforcement learning run on harder tasks, weighted toward problems that take many hours to complete. The company says it verifies its own work better, manages longer context better, and natively understands the Grok Bot harness for conversational tasks. It is served at the same price and speed as Grok 4.6.
It was trained on problems that take many hours to complete and is available inside Cursor and Grok Build, which makes it a fit for extended agentic coding sessions.
Knowledge Work
The company positions it for professional work such as creating documents and presentations, and for tasks done by lawyers, nurses, and financial analysts.
Agentic Tool Calling
xAI's API documentation describes it as its flagship model for code and everything else, with agentic tool calling and configurable reasoning effort.
Security Work
It ships with a new safeguard stack. Select cybersecurity partners get invite-only access to its red-team capabilities for defense research.
Strengths and limitations
Strengths
+Long-running coding and agentic tasks
+Professional knowledge work
+Configurable reasoning effort
+Same price and speed as Grok 4.6, per xAI
Limitations
−Closed-weight, so it cannot be self-hosted or fine-tuned on private data
−Smaller context window than the 1M-token models
