Microsoft and OpenAI have once again restructured their foundational agreement, an announcement made on Monday. While some social media commentary on X characterized this as a triumph for the ChatGPT creator over the Windows giant, analysis suggests that both entities have secured advantageous terms.
Crucially, this updated agreement resolves a significant challenge that had been looming over OpenAI since its substantial deal, potentially worth up to $50 billion, with Amazon.
Under the revised terms, Microsoft's previous exclusive access to all of OpenAI's products and intellectual property, which was contingent on OpenAI achieving Artificial General Intelligence (AGI), has been replaced with a clearly defined timeline. This new contract grants Microsoft a non-exclusive license to OpenAI's intellectual property for models and products, valid until 2032.
Microsoft retains its designation as OpenAI’s "primary cloud partner," indicating that Azure is expected to host the majority of OpenAI's cloud operations throughout the six-year duration of this agreement, even as OpenAI simultaneously pursues the development of its own data centers with other collaborators. This commitment is underscored by OpenAI's agreement in October to purchase an additional $250 billion in Microsoft cloud services, signaling to Microsoft shareholders that OpenAI will remain a substantial Azure client.
According to the companies, OpenAI products will be deployed "first on Azure, unless Microsoft is unable or unwilling to provide the requisite capabilities." However, a pivotal change is that "OpenAI can now serve all its products to customers across any cloud provider."
The precise meaning of "first" in this context remains unspecified within the announcement, leaving ambiguity as to whether it implies a temporary exclusivity on Azure or merely that Microsoft will be among the initial providers offering OpenAI's newest products.
Nevertheless, the most significant aspect of this particular term is its resolution of the potential for Microsoft to initiate legal action against OpenAI concerning the AI lab's agreement with Amazon.
To contextualize the previous complexities: In February, OpenAI revealed Amazon's commitment to invest up to $50 billion in the model developer. This sum included an initial $15 billion investment, with an additional $35 billion contingent on "certain conditions" being met "in the coming months," though the companies did not elaborate on these conditions.
As part of this arrangement, OpenAI committed to jointly developing "stateful runtime technology" on AWS Bedrock, Amazon Web Services' platform for delivering various AI models and services. Stateful runtime is critical technology that enables AI agents to retain memory of tasks and contexts over extended durations.
Furthermore, OpenAI had granted AWS exclusive rights to host its new agent-creation tool, Frontier. This particular clause became the point of contention.
OpenAI's prior agreement with Microsoft had explicitly prohibited OpenAI from offering Frontier exclusively on AWS, and potentially even restricted AWS from distributing it whatsoever.
Although Microsoft had previously permitted OpenAI to deploy certain selected products, such as the consumer version of ChatGPT, on alternative cloud providers, it had maintained exclusive rights to any OpenAI product accessed via an API, a category that included Frontier.
Indeed, on the very day OpenAI announced its agreement with AWS, Microsoft publicly challenged the terms regarding AWS's exclusivity, stating (with Microsoft's own emphasis):
"Microsoft upholds its exclusive license and access to intellectual property encompassing OpenAI models and products. ...Azure remains the exclusive cloud provider for stateless OpenAI APIs. ...Any stateless API calls to OpenAI models arising from a collaboration between OpenAI and any third party – Amazon included – would be hosted on Azure. ...OpenAI’s proprietary products, including Frontier, will continue to be hosted on Azure."
Microsoft also underscored that its original terms were valid until OpenAI achieved AGI. Reports from The Financial Times indicated that Microsoft had even considered pursuing legal action to enforce these contractual provisions.
Consequently, the newly forged agreement effectively revokes Microsoft’s exclusive rights, thereby mitigating the legal risks associated with the AWS partnership.
While demonstrably beneficial for OpenAI, Microsoft also secured several advantages. The new deal exempts Microsoft from paying a revenue share to OpenAI, whereas OpenAI will continue to remit a revenue share to Microsoft until 2030, albeit now subject to an established cap.
The precise financial sum that will accrue to Microsoft is currently indeterminate, though it is anticipated to be in the billions. Last quarter, Microsoft disclosed earnings of $7.5 billion from its investment in OpenAI within a single quarter.
A significant aspect is that Microsoft retains its position as a major shareholder in OpenAI, holding approximately 27 percent of the for-profit entity as reported in October. This ensures Microsoft financially benefits from OpenAI's expansion, including revenues generated through its sales on AWS.
The primary drawback for Microsoft, naturally, is the forfeiture of potential additional cloud service sales that an exclusive arrangement with OpenAI would have guaranteed.
This potential loss might be negligible, however. Much like OpenAI has actively engaged with Microsoft’s primary competitors, Microsoft itself has cultivated a close new partnership with Anthropic, a rival to OpenAI, utilizing its Claude AI to power agentic products for the cloud giant.
Ultimately, the most significant beneficiaries of these developments are enterprises, which now gain increased flexibility to select their preferred AI models and cloud providers as the industry's leading players vie to meet their demands.
Below is a chronological overview of the recent shifts in the relationship between Microsoft and OpenAI.
In October, Microsoft and OpenAI unveiled a new agreement designed to assist OpenAI in defending against a lawsuit from Elon Musk concerning its corporate structure, specifically granting OpenAI the capability to host non-API-accessed products on various cloud platforms.
November saw OpenAI and Amazon formalize their inaugural multi-year agreement, with OpenAI committing to procure $38 billion worth of AWS cloud services.
In February, Amazon announced an investment of up to $50 billion in OpenAI, conditional on "certain conditions," which encompassed an exclusive technology development and hosting agreement for Frontier and stateful technology. Concurrently, Microsoft publicly contested the notion of AWS holding exclusive rights to that technology.
March brought reports from the Financial Times indicating Microsoft's contemplation of legal action.
In April, OpenAI and Microsoft announced a new agreement, which introduces a fixed end date for their exclusive partnership and permits OpenAI to operate all its products on alternative cloud platforms. Under this new arrangement, Microsoft is no longer required to pay OpenAI a revenue share, while Microsoft continues to be a major shareholder in OpenAI.
