The new agreement “includes changes to the exclusivity on new capacity, moving to a model where Microsoft has a right of first refusal (ROFR),” Microsoft says. “To further support OpenAI, Microsoft has approved OpenAI’s ability to build additional capacity, primarily for research and training of models.”

The software giant was previously the exclusive cloud provider for OpenAI and now retains right of first refusal.

Microsoft Corp.'s US$13 billion investment in OpenAI raises concerns that the tech giant could extend its dominance in cloud computing into the nascent artificial intelligence market, the Federal Trade Commission said in a report released Friday.
