A new study from ETH Zurich examined context files such as Agents.md, a widely used convention for giving AI coding assistants project-specific instructions. The researchers found the practice offers little benefit and advise against relying on it. The work challenges an approach that has become common in AI-assisted software development workflows.
OpenAI said it will stop supplying its models to Cursor, the AI coding tool, after Cursor was acquired by SpaceX. The company described the move as a decision to wind down the existing contract. No timeline or further details on the transition were provided.
WHY IT MATTERS ↘OpenAI's decision to cut off Cursor after its acquisition by SpaceX underscores the growing risk that model providers will restrict access when their customers are acquired by large, potentially competitive entities, forcing AI tool developers to diversify their model dependencies or face sudden disruption. This move could accelerate the trend of vertical integration in AI, where companies build or acquire their own models to avoid supply chain vulnerabilities, ultimately raising costs and reducing flexibility for practitioners relying on third-party APIs.
