After the Compose 2 launch that caused a stir in the industry this week, the top AI coding tool Cursor found itself in a public controversy over "originality." The incident started when a social media user provided code evidence pointing out that this new model, which claims to have "peak-level programming intelligence," is actually based on the open-source model Kimi 2.5 recently released by Moonshot AI.
In response to the accusations, Lee Robinson, the vice president of education at Cursor, quickly replied, admitting that Composer 2 was indeed built on an open-source base. This statement quickly reversed the previous impression of "pure self-research," making the penetration of domestic large models into international top tools a focal point.
