I’m keeping an eye on Grok IA’s movements, and it looks like something interesting is coming. I heard that xAI is preparing a very significant expansion of its models in the coming months.

Grok 4.4 arrives in May with double the capacity of the previous model—we’re talking about 1 trillion parameters. This is quite robust. The model will incorporate training data up to the beginning of April, so it will have very recent information.

But then comes the plot twist: right after that, at the end of May, Grok 4.5 is released with even greater capacity, reaching 1.5 trillion parameters. That’s a fairly substantial jump from one to the other.

What I find interesting is this release pace—two models in less than a month. It really seems like Grok IA is betting on an aggressive expansion of capabilities. I’m curious to see how these new models will differentiate themselves in the AI market.
