OpenAI’s GPT‑6 Models and Codex Workflows Come to Google Cloud Marketplace

OpenAI and Google Cloud said Tuesday that OpenAI’s frontier models and Codex agentic workflows will be offered through Google Cloud’s Model Garden and sold via Google Cloud Marketplace, giving enterprise customers another major way to buy and use OpenAI tools through existing Google cloud contracts. The arrangement means customers can purchase the offerings on a single Google Cloud invoice, use existing spending commitments and have usage count toward Google’s Flexible Savings Plans.

The companies said the initial OpenAI models on Google Cloud will be GPT-6 Astra, GPT-6.1 Sol and GPT-6 Luna. Google Cloud said those models are rolling out now in private preview to select enterprise customers, with general availability planned in the coming weeks. Model Garden is Google Cloud’s catalog of first- and third-party foundation models, making the move as much a distribution and procurement expansion as a product launch.

For enterprise buyers, the commercial mechanics may matter as much as the models themselves. By routing transactions through Google Cloud Marketplace, companies can buy OpenAI services through their existing Google billing relationship instead of setting up a separate procurement path. Both companies said customers will be able to draw down existing Google Cloud spending commitments, see usage on one invoice and count that usage toward Google’s Flexible Savings Plans. Google Cloud also said private-preview customers can connect local Codex CLI and Desktop workflows directly to the Gemini platform for inference.

Google framed the partnership as part of a broader push to give customers more model choice on its AI platform. OpenAI said its models will also soon be available in Google Antigravity and the Gemini Agent, extending distribution beyond Model Garden. Alongside the launch, Google highlighted enterprise controls for third-party models on its platform, including strict data perimeters, isolated access boundaries with dedicated infrastructure, unified auditing and identity controls, and Zero Data Retention options coming soon.

The deal is the latest step in OpenAI’s broader cloud expansion this year beyond Microsoft Azure. On April 27, OpenAI said it had amended its partnership with Microsoft so Microsoft’s license became nonexclusive, while also saying Microsoft remained OpenAI’s primary cloud partner. That change opened the door to wider cloud distribution. OpenAI then announced cloud distribution partnerships with Amazon Web Services in February and Oracle in June. The Google Cloud agreement adds another major hyperscaler, potentially making OpenAI’s models easier for enterprises to buy where their infrastructure and budgets already sit.

OpenAI was explicit that the latest arrangement does not change Microsoft’s standing. In its announcement, the company said, “Microsoft remains OpenAI’s primary cloud partner.”

Greg Brockman, OpenAI’s president and co-founder, said in the company’s announcement that the partnership is meant to put OpenAI’s tools where businesses are already working. “Google Cloud is a leading platform for developers and businesses building AI agents, writing software, and putting AI to work,” Brockman said. “This partnership is an important step in making our most capable models and Codex available where customers are already building, giving them even more choice in how they use frontier AI as we grow the agentic ecosystem together.”

Neither company disclosed revenue-sharing percentages, pricing details or other commercial terms beyond the billing and commitment mechanics.
