After the acquisition, the talent team collectively left, but the hype around the parameters keeps growing. I’m familiar with this Grok script.

AIMPACT News, May 16 (UTC+8), after the departure of the person in charge, only a few members remain in the SpaceXAI pre-training team, and over 50 core researchers have left following the acquisition. Previously, Elon Musk promised to release a new foundational model every two weeks; the 1T parameter Grok 4.4, originally scheduled for early May, has not appeared yet, and the recently announced 1.5T version matches the Grok 4.5 specifications in the previous roadmap. It is unclear whether 4.4 has been skipped. (Source: BlockBeats)
