I think we can probably give you early access on Tuesday night.
Bear in mind, there is still a lot of polish to be done, but you will immediately notice the intelligence difference.

This may shock the media to hear but for 99.999% of its history there was not a Haitian TPS diaspora in Springfield, Ohio. The Democrats illegally airlifted the Haitian migrants to Springfield in the months before President Trump took office.

In addition to their excellent and unique training data, the Cursor team is also making major engineering contributions to v9 SFT & RL. It’s an honor and a pleasure to work with them.
For this 1.5T run, Cursor data was added in supplemental training, which is not quite as good as having it in initial training.
The 2T run that started a few weeks ago has greatly improved data in scope & scale in almost every arena, and many upgrades/fixes to the training recipe. That will finish in late July for August release.

To be clear, I’m not saying the Grok v9 foundation model will be mind-blowingly better than anything, but it will be a solid workhorse in the same league as Opus.
And the SpaceXAI cadence of model and harness improvement is speeding up tremendously, particularly due to a few dozen of the top Starlink/Starship engineers shifting a much of their time to AI.
Worth noting that the v8 foundation (Grok 4.3) model is a 0.5T model that finished training all the way back in December and has many fundamental flaws, so Grok 4.5 will feel like a gigantic upgrade!

Nearly all those who say the US should only admit the most talented immigrants would not themselves clear the bar they're proposing. They're effectively saying "Immigration is ok so long as you keep out people like me."

A big problem with research studies on AI models is that given how long the peer review process is, the results are always out-of-date by the time the paper is published.
