OpenAI brings GPT-6 Astra to Google Cloud's Model Garden

The arrangement places OpenAI's most advanced model inside a rival hyperscaler's marketplace. Google Cloud's Model Garden already offers more than 200 neural networks from Google, its partners and the open-source ecosystem, and OpenAI's lineup now joins that catalog. Google Cloud Chief Executive Thomas Kurian framed the move as giving customers a broad selection of models so they can pick the right one for each job, citing optimal quality and lower costs.

OpenAI is positioning Astra for enterprise use with safety optimizations. According to OpenAI, the model causes "fewer misaligned outcomes" than all the other frontier models it has evaluated, and it is configured not to bypass user-defined restrictions on the tasks it can perform. The company says Astra is responsible for several of the AI-produced math discoveries it has published in recent weeks, and it achieved a perfect score on ExploitBench, a benchmark that measures an LLM's ability to find and exploit cybersecurity flaws.

Beyond the Model Garden listing, the companies plan to bring the models to Google's Confidential Compute portfolio, which uses a server security feature called TEE to encrypt a segment of host memory so only a specific workload can access it. OpenAI also plans to make its models available via Google's Antigravity vibe coding tool and the Gemini Agent product for automating business tasks across cloud applications.
