xAI's Grok V9 Finishes Training — A 1.5-Trillion-Parameter Shot at Claude's Coding Crown

xAI's Grok V9-Medium, trained on Cursor developer workflows with 1.5 trillion parameters — three times the current Grok traffic model — has completed training with a mid-June release expected. Behind it, Grok 5 targets 6 trillion parameters on the Colossus 2 supercluster.
