OpenAI plans to add Alphabet's Google cloud service to meet its growing needs for computing capacity, three sources told Reuters, marking a surprising collaboration between two prominent competitors in the artificial intelligence sector.

OpenAI has signed a surprising deal with Google Cloud to access more computing power as ChatGPT's global usage soars. Despite being direct rivals in AI, the move marks a strategic shift for OpenAI, which has long relied on Microsoft Azure.

Under the new deal, Google Cloud will provide additional computing capacity to help OpenAI train and run its AI models. For OpenAI, the partnership addresses growing demands for computing power as the company's annual revenue reached $10 billion as of June, according to sources familiar with the matter who spoke to Reuters.
