OpenAI's frontier models and Codex land on Google Cloud

What happened: OpenAI and Google Cloud announced on Wednesday, 21 October, that OpenAI's frontier models and Codex agentic workflows are coming to Google Cloud's Model Garden, according to PYMNTS.

The details: Google Cloud customers can buy the models in Model Garden. They get "native access" for complex agentic workflows at scale, backed by Google Cloud's data governance and infrastructure.

Access through Google Antigravity and the Gemini Agent is "soon to come."

Why it matters: The companies pitch "model choice flexibility and the best model for each task" for enterprises. Customers can use OpenAI's models without leaving Google Cloud.

The context: PYMNTS, citing Reuters, says Google Cloud CEO Thomas Kurian has said the platform welcomes any model popular with developers. Hyperscalers are becoming the main commercial channels for frontier labs, and typically take a percentage of sales.

The rivals: Anthropic got 47% of its 2025 revenue from Amazon's and Google's cloud platforms, according to its IPO filing, as cited by Reuters via PYMNTS.

The catch: The source gives no pricing, no list of specific models and no launch dates. None of those details is confirmed.

What's next: Antigravity and Gemini Agent access is the next step, flagged only as "soon to come." No date has been given.
