xAI completed training of its 1.5 trillion parameter Grok V9 foundation model, which Elon Musk described as a major upgrade over the 0.5 trillion parameter Grok V8 now running as version 4.3

We are improving the 0.5T Grok foundation model V8 (public version 4.3) every few days.

The 1.5T V9 just finished training (incorrectly called pre-training) and is a major upgrade. Next, we are adding the Cursor data in supplemental training (others call this mid-training), then SFT and RL. About 3 or 4 weeks to release.

This will be a banger.
