Cursor just got BANNED (It's because of Elon...)

Matthew Berman explores the recent announcement by OpenAI that it will wind down its contract providing models to the AI coding platform Cursor. He argues this decision is a calculated move to prevent xAI, which recently acquired Cursor, from training its own competing models using OpenAI's proprietary data. The analysis details a complex history of adversarial relationships between key players, including OpenAI, xAI, Anthropic, and Google, highlighting the strategic importance of protecting AI models from 'distillation attacks'—a process where a less capable model is trained on the outputs of a stronger one. Berman explains that while Cursor users can still use their own API keys, the loss of native support for multiple integrated model providers significantly changes the platform's value proposition. He situates this conflict within the broader industry trend of companies becoming more vertically integrated, limiting cross-platform access to their foundational AI models to maintain a competitive advantage.
