Microsoft Expands GPT-6 Series with Two New Models
Microsoft has expanded its GPT-6 series by adding two new models to its lineup in Microsoft Foundry: GPT-6 Sol and GPT-6 Luna.
The GPT-6 Astra model, which was previously available, brings advanced reasoning and software engineering capabilities to demanding work that requires both judgment and action. It has seen a step-change in capabilities and strong cost-to-performance with the model using fewer, higher-value tokens to drive agents.
GPT-6 Sol is designed for general-purpose use, while GPT-6 Luna brings efficient intelligence to high-volume data and preparatory work.
Microsoft recommends customers start with GPT-6 Astra for demanding work. For higher-volume workloads, GPT-6 Sol and Luna can be used as complementary choices built for production and scale.
