Elon Musk said on July 8, 2026 that xAI's 2-trillion-parameter foundation model will finish training this month and be made available to customers next month, in August. He added that xAI would continue to refine the current 1.5-trillion-parameter foundation model and the Grok Build harness almost daily in response to user requests.

xAI's 2-Trillion-Parameter Flagship Finishes Training This Month — Customers Get It in August

Elon Musk says the new foundation model wraps training in July 2026 and ships to customers next month. He calls it "fully improved" over the current 1.5-trillion model — far more than a one-third parameter bump.

"Much more than a one-third increase"

Musk says every aspect of the model is improved over the 1.5T version. Expected qualitative gains:

Reasoning Coding Multimodal

Trained on the Colossus supercluster (GB300 GPUs). The 1.5T line reportedly used Cursor data in extra training, giving it a coding-oriented bent.

Optimists say

Potential to hit Claude Opus-class performance — faster, more token-efficient, and at lower cost.

Skeptics say

Bigger models bring usage limits and rising costs — practicality and stability come first. No real-world assessment yet; unreleased.

Still unannounced: pricing · benchmarks · context length · delivery format · model name. More expected after the August launch.
