Kosic will work on AI infrastructure projects at Prometheus, sources said.

xAI co-founder Kyle Kosic has left his role at OpenAI to join Jeff Bezos’s Project Prometheus, according to the Financial Times (FT).

Kosic’s departure from xAI in 2024 was the first of an exodus that saw the company’s 11th co-founder reportedly leave late last month, leaving Musk as the sole founding member left.

Kosic joined OpenAI shortly after leaving xAI. According to FT sources, he will work on AI infrastructure projects at Prometheus.

News of Bezos’s AI venture, codenamed Project Prometheus, surfaced last November. Bezos co-founded the company with former Google Life Sciences executive Vik Bajaj.

The company builds AI that assists engineering and manufacturing in a number of sectors, including in computers, aerospace and automobiles. It has already reportedly amassed billions in funding, partly from Bezos.

The FT reported that the two co-founders are leading efforts to raise “tens of billions of dollars or more” to acquire parts of companies likely to be disrupted by AI.

The company is also discussing investments with sovereign investment funds, including from Singapore and Gulf nations, the publication added. Additionally, it plans to collect stakes in companies across its target sectors for AI training data.

Prometheus had already hired around 100 employees across San Francisco, London and Zurich by November last year, including researchers from OpenAI, Google DeepMind and Meta. FT sources said that the company is hiring people with experience “building out massive infrastructure projects”.

Earlier this year, Jezz Bezos’s other venture Blue Origin announced a new satellite internet network called TeraWave, promising to deliver connection speeds of up to 6Tbps anywhere on Earth.

Currently, the satellite internet service sector is dominated by SpaceX’s Starlink, with its 9,000-plus satellites and roughly 9m customers. TeraWave, meanwhile, is planning a constellation of 5,408 satellites.
