Grok Build integrates with Composer 2.5: xAI Terminal Agent introduces Cursor key model

According to Visionary Beating monitoring, xAI, an artificial intelligence startup under Musk, announced that the command-line agent development tool Grok Build has fully launched support for Cursor's top-tier programming model Composer 2.5. Developers subscribed to X Premium+ or SuperGrok can now directly switch to Composer 2.5 in the terminal menu.

On May 18, Cursor released the high-performance programming-specific model Composer 2.5, emphasizing multi-file high-precision editing and long-range instruction compliance. The model is built on the open-source base Kimi K2.5, authorized for commercial use on the dark side of the moon, and underwent extensive reinforcement learning training and task distillation by the Cursor team. The training introduced the "text-feedback-assisted local reinforcement learning" technology, which provides targeted hints at precise nodes where tool invocation fails. The model can automatically correct local errors, improving the success rate of cross-file code refactoring and long-range execution.

Official demonstrations show that when faced with natural language instructions such as "improve mobile load menu responsiveness in games," the agent can autonomously retrieve relevant code. After running a regular retrieval on files like useMobile.ts and Game.tsx, the agent directly locates the specific implementation of localStorage in page.tsx for modification. The runtime interface supports quick commands such as `/fork` (clone the current session to a parallel sub-agent), `/compact` (compress history to reduce Token consumption), and `/copy` (copy the latest answer), and provides an "always-approve" automatic authorization mode.

The terminal ecosystem integration stems from Cursor's computational power-sharing collaboration with SpaceXAI. Currently, Cursor has access to computing resources, including the Colossus 2 supercluster, for model training. The integration of Composer 2.5 marks the first implementation of their cooperation in xAI terminal tools.
