SPACEXAI : Grok 4.8 will be a 2.5T-parameter model built on a new C++ software stack, and Elon Musk expects it to finish training this week. 

> While Grok 4.8 is in training, Grok 4.7 is still expected to arrive shortly, factoring in a previously communicated delay. 

> Grok 4.8 will be ±67% larger than Grok 4.6, which is currently available. This size puts it into the same tier as Kimi K3 with 2.8T params.
