For the first three years of the artificial intelligence boom, Amazon.com Inc. watched as cloud customers seeking the latest and greatest from OpenAI took their business to Microsoft Corp.

But the day after Amazon’s biggest cloud rival agreed to drop its exclusive rights to resell OpenAI products, Amazon says it will finally be able to make the ChatGPT maker’s AI models available to its own customers. 

“It’s something that our customers have asked for, for a really long time,” Matt Garman, CEO of the Amazon Web Services cloud unit, told Bloomberg Television. 

Some of OpenAI’s latest models will be available to preview on AWS starting April 28, with the most powerful GPT models arriving “in the next couple of weeks,” Garman said. 

Microsoft got a jump on the large language model era thanks to a massive early investment in OpenAI. That gave Microsoft’s Azure cloud unit exclusive rights to sell OpenAI’s most powerful models.

After the late 2022 launch of ChatGPT, Amazon scrambled to assemble a portfolio of the best of the rest on its Bedrock AI model marketplace, including products from OpenAI archrival Anthropic PBC and Meta Platforms. Still, some longtime AWS customers, including Superhuman, formerly Grammarly, turned to Microsoft for AI services. 

Amazon invested $50 billion in OpenAI earlier this year, by far its biggest investment in any business, and OpenAI said it would spend an additional $100 billion on AWS computing power and chips. 

“We absolutely are expecting a lot of growth there,” Garman said.

The two companies have jointly developed a product based on OpenAI’s models to help autonomous AI agents understand context and remember prior interactions with users. That tool, called Amazon Bedrock Managed Agents, was introduced April 28 at an event in San Francisco where AWS also announced a bigger push into business applications.

Business customers of OpenAI “want those models in a trusted environment that they know, and in a trusted infrastructure,” Denise Dresser, OpenAI’s chief revenue officer, said at the event.

Amazon’s tighter relationship with OpenAI coincides with growing worries that the richly valued startup won’t expand its sales fast enough to meet commitments it’s making to Amazon and other infrastructure providers, including Microsoft and Oracle Corp. 

On April 27, The Wall Street Journal reported that OpenAI had fallen short of several internal targets. OpenAI on April 28 pushed back, saying it was “firing on all cylinders.” 

AWS’ Garman said there was still more demand for AI services than supply of computing power to meet it. 

“The OpenAI team, I think, would gladly take more capacity from us this year and next year and the year after that as we add it,” he said. “And so we’re still working really hard to continue to add more capacity, whether it’s power, whether it’s chips, whether it’s memory, all around the world.”

Amazon ranks No. 1 on the Transport Topics Top 100 list of the largest logistics companies in North America, No. 15 on the TT Top 100 list of the largest private carriers and No. 1 on the TT Top 50 list of the largest global freight companies.
