What happened
In March 2024, Microsoft threatened legal action against OpenAI and Amazon. Microsoft alleged OpenAI's intent to sell its models through Amazon Web Services (AWS) violated its exclusivity agreement, which stipulates all OpenAI model API access must route through its Azure cloud platform. Microsoft claimed OpenAI had tried to find loopholes to avoid this agreement. OpenAI sought to sell its tokens via AWS, while Microsoft maintained its exclusive right to offer OpenAI's models as an API.
Why it matters
This dispute over API exclusivity creates significant uncertainty for procurement teams and platform engineers planning AI infrastructure. It signals increased vendor lock-in risks and potential restrictions on model access. The conflict highlights how cloud providers use existing agreements to control access to frontier models, potentially limiting multi-cloud strategies for enterprise AI deployments.
