Nvidia, Amazon, and Microsoft ‍are in talks to invest up to $US60 billion in OpenAI, The ​Information reports.

Nvidia, an existing investor whose chips ⁠power OpenAI’s AI models, is in talks to invest up to $US30 billion, The Information said, citing a person with knowledge of the situation.

Microsoft, a longstanding backer, is in talks to invest ‌less than $US10 billion, ​the report said. It added Amazon, which would be ‍a new investor, is in discussions to invest significantly more than $US10 billion, potentially even more than $US20 billion.

OpenAI is close to receiving term sheets, or an investment commitment, from these firms, the ​report said.

Nvidia, Amazon, Microsoft and ‌OpenAI did not immediately respond to Reuters’ requests for comment outside regular business hours.

Reuters could ​not immediately verify the report.

Amazon’s investment could depend on ‍separate negotiations, including a possible expansion of OpenAI’s cloud server rental deal with Amazon and a commercial agreement ​for ​OpenAI to sell its products, ​such as enterprise ChatGPT subscriptions, to Amazon, ​The Information said.

This follows reports from earlier this week that said that SoftBank Group is in talks to invest as much as an additional $US30 billion in OpenAI.

OpenAI is grappling with rising costs to train and run its AI models as competition from ‍Alphabet’s Google heats up.
