YouTuber Wes Roth rounds up the latest developments at xAI, Elon Musk’s AI company, painting a picture of an organization undergoing aggressive structural and personnel change ahead of what appears to be a major Grok 5 push. According to Roth, xAI is simultaneously training three Grok-build models, while Musk has acknowledged the company was not built correctly the first time and is being rebuilt from the foundations up. Ten of the original twelve xAI founders have departed, with burnout and performance pressure cited as causes.
On the hiring front, xAI has brought in Andrew Milik and Jason Ginsburg from Cursor — a signal that improving Grok’s coding capabilities is a top priority — along with Deventra Chaplot, a founding engineer at Thinking Machines Lab and former Mistral co-founder, who is expected to work on model training for Grok 5. The SpaceX merger has also consolidated Grok and the Colossus supercomputer cluster under the SpaceX umbrella, opening the door to potential space-based AI data center infrastructure. Musk has publicly stated xAI expects to match frontier competitors this year and surpass them significantly within three years.
Roth also shares firsthand impressions of Grok 4.20 for real-time web search, noting its ability to query X (formerly Twitter) gives it an edge for breaking news, and covers Grok’s recent API availability. He contextualizes xAI’s position against Anthropic, Google, and OpenAI using third-party competitive timelines, while noting Claude continues to dominate coding benchmarks like Coder Arena.
