xAI partners with Cursor Composer 2.5, coding on the terminal is about to change again

According to Beating Monitoring, Elon Musk’s AI startup xAI announced that the command-line intelligent agent development tool Grok Build has now been fully launched with Cursor’s top-tier programming model Composer 2.5. Developers subscribed to X Premium+ or SuperGrok can directly switch to Composer 2.5 in the terminal menu.

On May 18, Cursor released the high-performance programming-specific model Composer 2.5, focusing on multi-file high-precision editing and long-range instruction following. The model’s underlying foundation uses Kimi K2.5, an open-source base licensed for commercial use by the Dark Side of the Moon, and has been strengthened through large-scale reinforcement learning training and synthetic task distillation by the Cursor team. “Local reinforcement learning with text feedback” is introduced during training.
