Elon Musk says xAI will release Grok 4.6, a 1.5-trillion-parameter model with significantly improved supervised fine-tuning and reinforcement learning, around August 7.

A larger 2.1-trillion-parameter Grok 4.7 is set to follow a few weeks later. Musk says it will be better than 4.6 in every way and more token-efficient, though slightly slower to serve.

Both are steps up from xAI's current flagship, Grok 4.5, released in early July. As with any Musk timeline, the dates and specs are stated targets and could still slip. Note that xAI has no crypto token, and any "$GROK" or "xAI" presale is a scam.
