OpenAI said it has notified SpaceX that it intends to wind down the contract supplying its models to Cursor, giving the maximum notice the agreement allows and proposing a shutoff date of November 12. The company said it cannot be confident SpaceX will use the technology within its terms of service, citing Twitter's breach of an OpenAI contract after Musk acquired it and Musk's admission under oath this year that xAI had violated those same terms. OpenAI also named accountability for its upcoming Astra model as a factor. Cursor has run on OpenAI models for nearly four years.
Cursor, now owned by SpaceX, has started hosting code. Origin is in early beta on every paid plan and does repositories, browsing, and pull requests, with comments syncing both ways to GitHub within seconds so teams do not have to migrate. The timing is pointed: GitHub logged 257 outages over the past year, and one on the day that Origin launched pushed error rates near 20 percent worldwide.
SpaceX completed its all-stock purchase of Anysphere, the company behind the AI coding tool Cursor, issuing roughly 391 million Class A shares to do it. The deal was announced in June and cleared regulatory review in mid-August; Cursor now sits inside a new SpaceXAI division alongside xAI, which SpaceX absorbed earlier this year. Cursor framed the payoff as compute. The merger, it said, gives the tool access to the largest fleet of graphics processors in the world.
Elon Musk imposed a $200-per-week cap on Tesla employees' AI-tool spending, requiring manager sign-off to go over, according to The Information. Notably, the limit exempts his own Grok as well as Anysphere's Cursor, which Musk has pushed staff to use — a pointed carve-out for favored tools. Tesla joins Uber, Meta, Walmart, and Coinbase in reining in runaway AI bills, the latest sign that the "use all the AI you can" era is giving way to hard cost discipline.
Cursor released a public-beta iPhone app that lets developers kick off and supervise its autonomous coding agents away from the desk. It reflects Cursor 2.0's bet that people increasingly manage agents rather than type code — Anthropic's Boris Cherny says most of his coding now happens on his phone. The launch is the company's first major product move since its post-IPO acquisition by SpaceX, which is folding Cursor into its expanding software stack.
Cursor released Composer 2.5, an updated coding model built on Moonshot AI's open-source Kimi K2.5 checkpoint and trained with 25-times more synthetic tasks than Composer 2, plus a new sharded-Muon distributed-training setup. Cursor claims "substantial improvement in intelligence and behavior" on long-running tasks and complex instruction-following. Pricing is $0.50 per million input tokens and $2.50 per million output, with a fast variant at $3 and $15. The first week ships with double usage included.
