Overview
- The Financial Times reported that Microsoft is evaluating a lawsuit against OpenAI and Amazon over a deal that would reportedly make AWS the exclusive third‑party host for Frontier.
- The dispute hinges on whether Frontier constitutes stateful runtime access that OpenAI says can be hosted on AWS, versus stateless API calls that Microsoft says must route through Azure.
- In a joint statement last month, Microsoft and OpenAI said Azure remains the exclusive cloud for OpenAI’s models and that Frontier would continue to be hosted on Azure.
- No lawsuit has been filed, and the companies are reported to be in negotiations to resolve the disagreement ahead of Frontier’s launch.
- Reporting indicates a legal fight could draw antitrust scrutiny and complicate OpenAI’s potential IPO timeline.
