Brief

@ivanfioravanti expresses a desire to work at SpaceX to access and experiment with the latest models and hardware. They quote Elon Musk's June 28, 2026 tweet announcing Grok 4.5—based on a 1.5T V9 foundation model with Cursor data, in private beta at SpaceX and Tesla, with early evaluations near or exceeding Opus, ongoing RL gains, and monthly from-scratch releases in 2026.

Why it matters

@ivanfioravanti says they want to work at SpaceX specifically to try, play with, and interact with the latest models on SpaceX hardware.

Key details

  • Elon Musk (tweet dated 2026-06-28) announced Grok 4.5: built on a 1.5T V9 foundation model with Cursor data added in supplemental training, now in private beta at SpaceX & Tesla; early evals are "close to, perhaps exceeding Opus," RL and the Grok Build harness are improving, and SpaceX will release completely trained-from-scratch new models every month in 2026.
Source evidence

I'd like to work for SpaceX just to be able to try, play and interact with latest and greatest models on the amazing hardware they have there! 🤩

Elon Musk (@elonmusk)

Grok 4.5, based on our 1.5T V9 foundation model, with Cursor data added in supplemental training, is now in private beta at SpaceX & Tesla. Early evals show performance close to, perhaps exceeding Opus.

RL is continuing to significantly improve the model, and the Grok Build harness gets better every day.

Nice work by all those involved!

Completely trained from scratch new models will be released by @SpaceX every month this year.
