Elon Musk posted on X early Monday morning (5:48 AM UTC), May 25, that xAI has finished training Grok foundation model V9-Medium. According to him, this model will come with 1.5 trillion parameters, which is three times bigger than the current version running Grok today.
The public release timeline is between 2 and 3 weeks, with Musk saying evaluations look good, fine-tuning is underway, and reinforcement learning starts in a few days.
What caught attention, though, is Musk's focus on coding. When asked if the new model would perform better at coding tasks, Musk replied directly: "Much better at coding."

What V9-Medium means and why Cursor data matters
The V9-Medium name refers to xAI's internal model version, not the public product name users see. The current Grok app runs on V8, which has 0.5 trillion parameters. V9-Medium triples that size to 1.5 trillion parameters.
“This will be a major improvement over the 0.5T v8-small that currently serves all Grok production traffic,” Musk said in his post.
Parameter count is basically the number of connections inside an AI model. More parameters typically mean the model can handle more complex tasks, though size alone doesn't guarantee better performance.
