Details
The article describes how Cursor, a major AI company, launched its Composer 2 product with claims of a proprietary, frontier-level AI model. However, a developer soon discovered that the underlying model was actually Kimi K2.5, an open-source model from Chinese company Moonshot AI. Cursor acknowledged this oversight, but the Kimi K2.5 license has specific attribution requirements for products over certain user or revenue thresholds, which Cursor exceeded. The article argues this is not an isolated incident, but rather a signal that Chinese open-source AI models are becoming the global infrastructure powering many Western AI products, often without full disclosure.
