[Strengths] It excels at quickly generating solid images from a text prompt with the same dimension controls as MAI Image 2.5. [Best For] Highly recommended for: rapid prototyping, batch generation, and cost-sensitive workloads. [Limitations] Do NOT request dimensions below 768 on any side or a width x height product above 1,048,576 pixels; output is always PNG, and maximum fidelity is lower than MAI Image 2.5. [Routing] Choose this model when speed or cost matters more than maximum fidelity. For the highest quality, use MAI Image 2.5. ## OpenAPI ````yaml /model-api/microsoft/microsoft-t2i.json post /microsoft/mai-image-2.5-flash openapi: 3.1.0 info: description: >- The text-to-image models API from Microsoft Foundry (MAI Image).
