OpenAI, the artificial intelligence research lab behind ChatGPT, has officially listed Google Cloud as one of its cloud infrastructure partners. This move reflects OpenAI’s growing need for computing power to train and deploy advanced AI models as global demand accelerates.
OpenAI Expands Beyond Microsoft: Why Google Cloud Partnership Matters
According to an updated supplier list published on OpenAI’s website, Alphabet’s Google Cloud now joins Microsoft, Oracle, and CoreWeave as a key provider of computing capacity for OpenAI. The partnership with Google was finalised in May 2025 following months of negotiation, as initially reported by Reuters in June.
This deal marks a significant shift in the competitive landscape of the AI industry. OpenAI had been exclusively reliant on Microsoft Azure cloud services until January 2025. By onboarding Google Cloud, OpenAI is now diversifying its cloud infrastructure sources, ensuring greater resilience and scalability.
The Scale of OpenAI’s Infrastructure: Stargate and Beyond
Earlier this year, OpenAI also announced a partnership with SoftBank and Oracle as part of its $500 billion Stargate project—a mega-scale AI data centre initiative. Additionally, OpenAI signed multi-billion-dollar agreements with CoreWeave to further boost its computing resources.
The Google Cloud partnership adds another layer to OpenAI’s expanding infrastructure footprint. According to insiders, OpenAI and Google had been in talks for several months, but contractual restrictions with Microsoft initially prevented them from finalising a deal.
What This Means for the AI Industry
The new arrangement between OpenAI and Google Cloud signals several important trends in the artificial intelligence sector:
- Growing Compute Demands: Training large AI models such as GPT-4.5 and GPT-5 requires increasingly vast computing resources.
- Diversification of Cloud Providers: OpenAI is moving away from reliance on a single partner, such as Microsoft Azure, to ensure flexibility and reduce risk.
- Increased Competition Among Cloud Providers: Google, Microsoft, Oracle, and CoreWeave are now directly competing to supply the AI industry with infrastructure services.
Key Takeaways:
- Google Cloud joins OpenAI’s list of official cloud partners alongside Microsoft, Oracle, and CoreWeave.
- The deal was finalised in May 2025 after months of negotiations.
- OpenAI is diversifying beyond Microsoft Azure to meet growing AI computing needs.
- The partnership strengthens OpenAI’s position in large-scale AI training and deployment.
