OpenAI brings frontier models and Codex workflows to Google Cloud

News

OpenAI said its frontier models and Codex workflows will be available in Gemini’s Model Garden through Google Cloud Marketplace.

OpenAI said on Wednesday that its frontier models and Codex workflows are coming to Gemini’s Model Garden through Google Cloud Marketplace, extending distribution for its developer and coding tools inside Google Cloud’s ecosystem.

Evidence and context

The company’s announcement did not name specific pricing, rollout dates or customer eligibility details in the supplied material. The key verified development is the channel itself: OpenAI and Google Cloud are making frontier models and Codex workflows available through Gemini’s Model Garden on Google Cloud Marketplace, according to OpenAI’s Oct. 21, 2026 post.

The move lands alongside a broader product cycle for OpenAI’s coding stack. OpenAI said on Oct. 19, 2026 that it was advancing coding in low-resource programming languages, and earlier release notes on Oct. 9, 2026 referenced beta composer predictions in Codex for eligible personal ChatGPT Pro users. OpenAI also said on Oct. 7, 2026 that GPT-6 and Intelligent UI were rolling out in ChatGPT, while noting that release did not change the models powering Work and Codex.

OpenAI’s verified background material as of Oct. 21, 2026 shows its frontier lineup includes GPT-6 Astra, GPT-6.1 Sol and GPT-6 Luna. OpenAI describes Astra as its highest-intelligence model, Sol as a capability-cost balance and Luna as an efficient everyday model. GPT-6.1 Sol was introduced on Sept. 29, 2026 for ChatGPT Work, Codex and the API, with published standard API rates of $2 per million input tokens, $0.10 per million cached input tokens and $10 per million output tokens; those are usage prices, not market prices.

OpenAI’s Codex is a coding-agent product rather than a single model, and its availability can vary by client configuration, plan and workspace permissions. That distinction matters here because the new Google Cloud distribution concerns both frontier models and Codex workflows, rather than a simple model listing. The supplied material does not state whether the Google Cloud availability changes model access, pricing or approval requirements for existing users.
