    Why experts doubt Kimi K3 is just distilled Fable

    White House science advisor Michael Kratsios just accused Moonshot of copying Anthropic's Fable to build its open-weight Kimi K3 model, but AI researchers are skeptical. Experts pointed out that Fable only launched on July 1st, making a two-week distillation and training turnaround virtually impossible, while frontier Chinese labs increasingly rely on reinforcement learning rather than simple fine-tuning.

    Cursor drops Composer 2.5 with 25x more synthetic training tasks

    Cursor just launched Composer 2.5, a major upgrade to its flagship AI coding agent built on Moonshot's open-source Kimi K2.5 checkpoint. The update scales synthetic training tasks by 25x and introduces targeted textual feedback to fix localized RL errors during marathon coding sessions. Why it matters: Cursor is solving agent reliability on complex real-world codebases while quietly partnering with SpaceXAI to train an even larger model.
