MAI-1-preview is a model record from **Microsoft** in the MAI family. [Source](https://microsoft.ai/news-categories/models/page/2/) A separate version identifier is not documented in this record; the model name alone does not establish which snapshot a service runs. ### How can you access MAI-1-preview? The catalog documents **API** access for MAI-1-preview. [Source](https://microsoft.ai/news-categories/models/page/2/) As of the catalog check, this version was listed as a preview. [Source](https://microsoft.ai/news-categories/models/page/2/) For API use, confirm the exact model identifier, your account and region, and the endpoint's current limits in the linked documentation. An API listing does not establish access through a consumer subscription. ### What dates are documented for MAI-1-preview? **Release date: August 28, 2025.** [Source](https://microsoft.ai/news-categories/models/page/2/) This is a release milestone, not a knowledge or training cutoff. The source labels this “Publisher release date.” Neither a knowledge cutoff nor a training-data cutoff is established here. A release date, repository upload or filename cannot supply those missing dates. ### What can MAI-1-preview receive and generate? Documented inputs: **text**. [Source](https://microsoft.ai/news-categories/models/page/2/) Documented outputs: **text**. [Source](https://microsoft.ai/news-categories/models/page/2/) Input support and output generation are separate capabilities. Reading an image does not establish image generation; a text output listing does not establish speech output. File sizes, formats and media limits depend on the documented implementation. ### What distinguishes MAI-1-preview? These details come from the linked publisher material for this model. Reported capabilities and training descriptions are publisher statements, not independent test results. **Original preview access**: The dated announcement introduced public testing on LMArena and an application for trusted-tester API access. It announced later Copilot rollout rather than unrestricted API availability. [Source](https://microsoft.ai/news-categories/models/page/2/) **Architecture**: Microsoft described the original preview as a mixture-of-experts model trained end to end. The reported training GPU count is not a model parameter count or a self-hosting requirement. [Source](https://microsoft.ai/news-categories/models/page/2/) **Catalog qualifications:** The original announcement describes preview access limited to trusted API testers; current general availability is unverified. **Evidence still missing here:** complete input/output pricing, context or input capacity, and knowledge and training-data cutoffs. Missing documentation is not evidence that a feature is unavailable. Headless Thrones has not independently benchmarked this model for this reference. Evaluate it on representative work before choosing it; these facts do not rank its accuracy, reliability, speed or suitability against another model. Keep the exact version in view ## Other MAI models from Microsoft. These are separate records in the same publisher family. A shared family name does not establish equal capabilities or interchangeable licenses. ### [MAI-Code-1.1-Flash](https://headlessthrones.com/models/microsoft-mai-code-1-1-flash) Open weights · 256,000 context tokens ### [MAI-Code-1-Flash](https://headlessthrones.com/models/microsoft-mai-code-1-flash) GitHub Copilot ### [MAI-Cyber-1-Flash](https://headlessthrones.com/models/microsoft-mai-cyber-1-flash) MDASH private preview for approved defenders ### [MAI-DS-R1](https://headlessthrones.com/models/microsoft-mai-ds-r1) Open weights ### [MAI-Thinking-1](https://headlessthrones.com/models/microsoft-mai-thinking-1) API
