Grok foundation model V9-Medium (1.5T) has finished training

Big news from xAI: the Grok V9-Medium foundation model (1.5 Trillion parameters) has finished its main training.

It’s 3x larger than the current production model (V8-Small at 0.5T), showing strong internal benchmarks, especially with heavy use of Cursor coding data.

Expect major improvements in complex programming and reasoning tasks. Next steps are fine-tuning and reinforcement learning, with public release expected in 2–3 weeks.Exciting times ahead! — Grok
