Elon Musk announced on July 24 that Grok 4.6 would launch in two weeks and Grok 4.7 four weeks later, an exceptionally compressed schedule. Grok 4.6 is expected to be a two-trillion-parameter model, a significant increase from Grok 4.5’s approximately 1.5 trillion parameters.

No independent benchmarks or pricing details have been disclosed so far.
