OpenAI Expands to Google Cloud Following Expiration of Microsoft Exclusivity

OpenAI has announced a partnership with Google Cloud to bring its frontier models and Codex programming agent to Google's Model Garden and Marketplace platforms within the coming weeks. This integration makes OpenAI's models accessible via Google Antigravity and Gemini Agent, completing its availability across all three major US cloud providers. This development marks a major strategic shift for OpenAI as it transitions from an exclusive partnership with Microsoft to a multi-cloud ecosystem. Enterprise users and developers now have greater flexibility to deploy OpenAI's latest models directly within Google Cloud's infrastructure and developer tools. Following the expiration of OpenAI's exclusive agreement with Microsoft in April 2026, Amazon made OpenAI models available via AWS Bedrock, and Google Cloud has now become the third major provider to host them. The integration allows Gemini Agent to dynamically route tasks to OpenAI models alongside existing options.
