Jan 30 (Reuters) - Nvidia's ( NVDA ) plan to invest up

to $100 billion in OpenAI to help it train ‌and run its latest

artificial-intelligence models has stalled ​after some inside the

chip giant expressed ‍doubts about the deal, the ⁠Wall Street

Journal ⁠reported on Friday.

Both companies are rethinking the ‌future of their

partnership, and ​the latest discussions include an equity

investment of tens of billions ⁠of dollars ‍as part ​of OpenAI's

current funding round, the Journal said, citing people familiar

with the ‍matter.

Nvidia ( NVDA ) CEO Jensen Huang has privately emphasized to industry

associates in recent months that the original $100 billion

agreement was non-binding and not finalized, the report ​said.

Huang ‍has also privately criticized what he has

described as a lack ​of discipline in OpenAI's business approach

and expressed concern about the competition it faces from the

likes of Alphabet's Google and Anthropic, the WSJ

added.

Reuters could not immediately verify ​the report. OpenAI and

Nvidia ( NVDA ) did not immediately respond to Reuters' request for

comment.
