OpenAI models arrive on Google Cloud

Overview

Updated Oct 22

OpenAI's GPT-6 models and its Codex coding agent are moving into Google Cloud's Model Garden. The three models, Astra, Sol and Luna, are in private preview for select enterprise customers, and the companies say general availability is weeks away.

Buyers will purchase the models through Google Cloud Marketplace, so the spending draws down existing Google Cloud commitments and shows up on one invoice. Google says it is the only major cloud provider carrying OpenAI, Anthropic and its own Gemini models in a single catalog. OpenAI models are also set to appear inside Google's Antigravity coding tool and the Gemini Agent.

Why it matters

Enterprises can now use existing Google Cloud budgets for OpenAI models, making multi-model AI adoption cheaper and simpler.

Scenarios

OpenAI models reach general availability on Google Cloud

Likely Resolves by Jan 31, 2027

Discussed by: OpenAI and Google Cloud announcements

The private preview expands to general availability in the coming weeks. Enterprise customers begin purchasing OpenAI models through Google Cloud Marketplace, drawing down their Google Cloud commitments. This would make Google Cloud a major distribution channel for OpenAI.

Regulators open antitrust probe into OpenAI's multi-cloud deals

Possible Resolves by Q2 2027

Discussed by: Reuters

The partnership draws scrutiny from regulators concerned about OpenAI's distribution across all three major cloud providers. A formal investigation by the Department of Justice or Federal Trade Commission would signal that regulators see the deals as potentially anticompetitive.

Microsoft and OpenAI renegotiate their partnership

Possible Resolves by End of 2027

Discussed by: CNBC

As OpenAI diversifies across clouds, Microsoft and OpenAI renegotiate their partnership terms. This could reduce Microsoft's exclusive access to OpenAI models or change the revenue-sharing arrangement. The renegotiation would reflect OpenAI's new multi-cloud reality.

OpenAI models go live inside Google Antigravity and the Gemini Agent

Likely Resolves by End of 2026

Discussed by: OpenAI and Google Cloud announcements

Both companies said OpenAI models will soon be selectable in Google's Antigravity development environment and in the Gemini Agent, alongside Gemini and other models. A live rollout would put OpenAI's models in front of Google Cloud customers who never open the Model Garden directly.

Historical Context

2 moments from history that rhyme with this story — and how they unfolded.

2019 - April 2026

Microsoft-OpenAI exclusive deal (2019-2026)

Microsoft invested billions in OpenAI and became its exclusive cloud provider, giving Azure sole access to GPT models for enterprise workloads. The arrangement made Microsoft the primary commercial channel for OpenAI's technology.

Then

Azure became the default cloud for OpenAI customers, and Microsoft integrated GPT models into its products.

Now

The deal shaped the AI industry's cloud economics, with major cloud providers competing to host frontier AI models.

Why this matters now

The expiration of this exclusivity in April 2026 opened the door for OpenAI to distribute through AWS and Google Cloud.

September 2023

AWS-Anthropic partnership (2023)

Amazon invested billions in Anthropic, making AWS Anthropic's primary cloud provider. The deal gave AWS access to Claude models and positioned Amazon as a major AI infrastructure player.

Then

Anthropic's Claude models became available on AWS Bedrock, competing with Microsoft-OpenAI.

Now

The deal showed that major cloud providers would back rival AI labs, setting the pattern for multi-cloud AI distribution.

Why this matters now

Google Cloud's partnership with OpenAI follows the same pattern, with cloud providers hosting models from multiple AI labs.
