Cursor is now part of @SpaceX.
Today, we have officially closed our acquisition. We will join the @SpaceXAI team to help make Grok the world's most useful AI and improve Grok Build, Grok Bot, Grok API, Cursor, and more.
SpaceX has built some of the most inspiring and impressive technology in the world, and we’re grateful for the opportunity to become part of such a special company. Onwards.

Introducing Rollouts.
Rollouts write a monitoring plan, then watch changes as they deploy.
Deployments are verified, so regressions are caught before users see them.

We've reduced token costs in Cursor by 7% with no drop in agent quality.
Savings came from tighter prompts, selective tool loading, better caching, and compressed file reads.

Introducing Projects, a new way of working in Cursor.
Rather than creating a chat for every task, you work with a coordinator agent in a single, persistent thread.
Like @bot, your agent is always on, proactively manages work with subagents, and improves over time.

You can now run Cursor cloud agents on your infrastructure, including pools of machines that automatically scale with demand.
This lets you give agents access to internal services or specialized hardware, while the agent loop stays in Cursor.

Claude Fable 5.1 is now available in Cursor!
It's the most capable model we’ve run on CursorBench 3.2, scoring 73.4% at max effort.
We found it especially skilled at verifying its own work, allowing it to take on difficult coding tasks from start to finish.

Cursor retweeted
We’re sorry to see that OpenAI put out a note saying they plan to block Cursor users from accessing OpenAI models in three months.
OpenAI models serve about 5% of Cursor user traffic, and we’re speaking with the OpenAI team to resolve this.
Cursor was one of the very first users of OpenAI, we’ve worked closely with their team for years, and we’ve trusted their platform to be neutral infrastructure for our business.
