OpenAI plans to make its latest large language models available in Google Cloud through Alphabet's Model Garden service, which already offers access to more than 200 neural networks. The first model OpenAI is bringing is its flagship GPT-6 Astra, which the company says is responsible for several of its published AI-produced math discoveries and achieved a perfect score on ExploitBench, a benchmark measuring how well LLMs find and exploit cybersecurity flaws. Astra includes safety optimizations for enterprise use; according to OpenAI, it 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. Google Cloud customers will also get GPT-6.1 Sol and GPT-6 Luna, two scaled-down versions of Astra that OpenAI launched in late September and that trade off some output quality for a significant reduction in token pricing, costing five and 100 times less than Astra respectively. OpenAI says Google Cloud customers can pay for access using the long-term spending commitments cloud providers offer enterprises, removing the need to set up a new AI budget and easing procurement. Astra, Sol and Luna will become generally available in Model Garden within a few weeks, and the companies plan to follow up by bringing the models to Google's Confidential Compute portfolio, which uses TEE to encrypt a segment of host server memory so only a specific workload can reach it. OpenAI also plans to make its models available via Google's Antigravity vibe coding tool and Gemini Agent, which automates business tasks spanning multiple cloud applications.
