OpenAI models to launch on Google Cloud Model Garden

On October 21, 2026 (local time), OpenAI and Google Cloud announced a partnership to bring OpenAI's frontier large language models and Codex workflows to the Model Garden on Google Cloud, with enterprise access distributed through Google Cloud Marketplace. According to CNBC, OpenAI said its AI models would be available through Google Cloud's Model Garden and its Antigravity coding tool in the coming weeks, following a launch on AWS earlier that year. CNBC noted that OpenAI's models would now sit on all three of the top clouds, giving corporate developers more choice.

The Next Web reported that OpenAI is bringing its Codex coding agent and three frontier models, GPT-6 Astra, GPT-6.1 Sol, and GPT-6 Luna, to Google Cloud. Those three models are rolling out now in private preview through the Model Garden, with select enterprise customers getting access first; OpenAI plans general availability in the coming weeks. IT之家 described Codex as a coding agent and added that, alongside Anthropic's latest closed-source Claude models, OpenAI's newest closed-source GPT models would also be offered through Google Antigravity and Gemini Agent. IT之家 further noted that after OpenAI's exclusive agreement with Microsoft expired in April 2026, Amazon announced the next day that it would host OpenAI models through AWS Bedrock, and Google Cloud has now become the third. A Juejin article said the Codex agent was listed as a product on Google Cloud and claimed this is the first time models from Gemini, Claude, and GPT have appeared together on a single cloud platform. As of October 23, the models were still in private preview, with general availability yet to be confirmed.
