A team of 50 people leaving, the promise of a new version every two weeks now seems like dark humor; layoffs in the AI industry are more efficient than training.

AIMPACT News, May 16 (UTC+8), after the departure of the lead, 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 yet appeared, 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)
