Grok Build integrates Composer 2.5: xAI terminal intelligent agent introduces main model of cursor According to Beating monitoring, Musk's artificial intelligence startup xAI announced that the command line agent development tool Grok Build has fully launched Composer 2.5, a top-level programming model developed by Cursor. Developers who subscribe to X Premium+or SuperGrok can switch directly to Composer 2.5 in the terminal menu. Cursor released the high-performance programming specific model Composer 2.5 on May 18th, which focuses on high-precision editing of multiple files and compliance with long-range instructions. The bottom layer of the model adopts the open-source substrate Kimi K2.5 licensed for commercial use by the Dark Side of the Moon, and is trained and synthesized on a large scale by the Cursor team for task distillation. The 'Local Reinforcement Learning with Text Feedback' technique introduced during training can provide targeted prompts at precise nodes where tool calls fail. The model can automatically correct local errors, improving the success rate of cross file code refactoring and long-distance running. The official demonstration shows that when faced with natural language commands such as "enhancing the mobile responsive experience of game loading menus," the agent can autonomously retrieve relevant code. After running regular retrieval on files such as useMobile.ts and Game.tsx, the agent directly locates the specific implementation of localStorage in page.tsx for modification. The runtime interface supports shortcut commands such as'/work '(cloning the current session to a parallel sub agent),'/compact '(compressing history to reduce token consumption), and'/copy '(copying the latest answer), and provides an' always approve 'automatic authorization mode. The terminal ecosystem docking originated from the computing power sharing cooperation between Cursor and SpaceXAI. At present, Cursor has accessed computing resources including the Colossus 2 super cluster for model training, and the introduction of Composer 2.5 is the first landing of the collaboration between the two parties on the xAI terminal tool.
