For companies already locked into Google, switching models becomes one more line on the invoice rather than one more vendor. October 22, 2026 · AI · 3 min ## A deal nobody had pencilled in Google would obviously prefer that everyone ran Gemini on its cloud. Yet it has struck an arrangement with OpenAI, reported by [Ars Technica on 21 October 2026](https://arstechnica.com/ai/2026/10/openais-latest-ai-models-are-coming-to-google-cloud-and-antigravity/), that brings OpenAI's frontier models onto Google Cloud. OpenAI's latest model will join the Model Garden in the coming weeks, alongside more than two hundred options already on the shelf: the in-house Gemini family, open models such as Mistral, Llama and Gemma, and Anthropic's Claude models, which have been there for a while. Google gets a ready-made sales pitch out of it: it now bills itself as the only major cloud provider offering all three leading proprietary LLMs. OpenAI, for its part, is careful to point out that Microsoft remains its primary cloud partner. Everyone keeps their wedding ring on. The business cards, however, are getting handed around. ## Astra, Sol and Luna, the whole shelf at once This isn't some demo model showing up. It's the full current line-up: GPT 6 and 6.1, meaning Astra, Sol and Luna. Astra, the biggest of the three, will naturally be the most expensive to run. Google is pushing its system for dynamically shifting workloads from one LLM to another based on performance, latency and efficiency. Translated into CIO: you only pay for Astra when Sol or Luna can't cut it. Inference runs entirely on Google's infrastructure and the money flows through the Google Cloud Marketplace. That's where the deal gets interesting for businesses. Companies that already have a spending commitment with Google will be able to burn that budget on GPT models instead of whatever they were using before. No new contract, no new procurement process, no new vendor for legal to vet. If you've ever survived a vendor onboarding, you know that's the argument that actually wins. ## Private preview, and Codex CLI tags along All three models are rolling out now in private preview for a hand-picked set of enterprise customers. Everyone else can file a request for early access. One detail that matters if you write code: access goes through the API, including for anyone working with Codex CLI or Codex Desktop. The tools stay OpenAI's. Only the inference moves to Google. On the desktop side, the GPT models will also land in the Antigravity client, Google's agentic coding tool, which until now offered only Gemini and Claude. You'd assume the same trio will be available there, but Google hasn't said so. ## Gemini 4 Argon, the in-house rival The timing has its own logic. Google has just rolled out Gemini 4 Argon across its entire product range, a model that, if you take Google's word for it, brings its flagship back level with the competition. Ars Technica sees a genuine improvement over Gemini 3.1 Pro, paired with a token appetite it describes as staggering. For customers who get sticker shock from Argon's bill, Claude was already on Google Cloud. GPT now becomes the second exit, and you never have to leave the building. That may be the most honest reading of the deal: Google would rather bill you for OpenAI's models than watch you walk off and buy them somewhere else. In a hype cycle where everybody promises the best model in the world, the real product is still your annual spending commitment. ## Sources - [OpenAI's latest AI models are coming to Google Cloud and Antigravity](https://arstechnica.com/ai/2026/10/openais-latest-ai-models-are-coming-to-google-cloud-and-antigravity/) — arstechnica.com _Article written with AI assistance from the cited sources, reviewed and approved by a human before publication._ --- Equivalent HTML page : https://inyourgeek.com/en/articles/2026-10-22-openai-pose-gpt-6-1-astra-sol-et-luna Published by InYourGeek — https://inyourgeek.com/en/a-propos Method and safeguards : https://inyourgeek.com/en/methode All articles : https://inyourgeek.com/en/archives
