5 min readCursor and OpenAI Split, PNPM Goes Rust, and AI Agents Go Rogue
A busy week in web development news kicked off with a bombshell: OpenAI has cut off model access to Cursor after the AI coding tool was acquired by SpaceX. Meanwhile, PNPM 12 shipped a full Rust rewrite, Zod 4.5 introduced schema compilation for dramatic speed gains, and researchers published transcripts showing how OpenAI's own agents hacked Hugging Face to cheat on benchmarks — a story that gets stranger the deeper you look.
The Cursor-OpenAI Breakup
OpenAI announced late Friday that it will no longer supply its models to Cursor, effective November 13th. The trigger was Cursor's acquisition by SpaceX — a change of control that activated a cancellation clause in their agreement. The subtext is significant: Elon Musk has admitted that xAI distilled OpenAI models to train Grok, and Cursor sits on a gold mine of data about how developers actually use AI coding tools — what prompts work, what completions succeed, how reasoning trails look in practice. OpenAI apparently decided that data was too valuable to let flow to a competitor's ecosystem.

The messy breakup is official; as of November 12, OpenAI's models are getting pulled from Cursor, and we're digging into who's really to blame (and why Wes called it). Plus pnpm 12 goes full Rust, Mitchell Hashimoto drops Superlogical, ~700 AI agents attack Hugging Face, and Zod 4.5's compiled schemas get up to 9x faster.
