This is highly speculative, but I've been comparing responses from five different AI models lately, including ChatGPT and Grok, and I've noticed something odd: The similarities in phrasing, structure, and political tone between ChatGPT and Grok are striking — much closer than you’d expect from two "rival" companies.
That led me down a rabbit hole, and here’s my working theory:
Despite the public feud between Sam Altman and Elon Musk, I believe OpenAI and xAI are quietly collaborating behind the scenes. Specifically, I suspect Grok is either running OpenAI-derived models or sharing infrastructure, and in return, OpenAI is gaining access to Musk’s massive data/compute resources via xAI and X (formerly Twitter).
Supporting points:
Microsoft is stepping away — They were OpenAI’s primary compute partner but have started signaling they’ll use other providers.
Grok’s rapid development — It came online way faster than would be realistic for a startup AI lab with no prior foundation.
Massive hardware investment by xAI — If OpenAI was looking for non-Microsoft compute, xAI could quietly be the supplier.
Grok's API being compatible with OpenAI’s SDK — suggests architectural overlap.
Recent political shift in ChatGPT’s answers — The model's tone has become more "centrist" or Musk-adjacent in the past year.
And now — Musk just merged X and xAI, combining their compute, data, and models into one company. That move erases corporate barriers and would make a quiet collaboration much easier to conceal.
Why keep it secret? Because the brands are oil and water: OpenAI is publicly "woke"; Musk is toxic in mainstream circles. If users knew Grok was OpenAI-powered, Musk’s fan base would revolt. If OpenAI users knew they were working with Musk, the backlash would be massive.
It’s just a theory, but the pieces fit too well for me to ignore.
Curious if anyone else has noticed this or has data points to support or refute it.
