Hosted mask generation models

Mask generation models produce per-pixel segmentation masks that delineate objects or regions within an image. They solve problems such as isolating a subject from its background for e-commerce product photography, identifying anatomical structures in medical imaging, and separating vehicles and pedestrians in autonomous driving perception pipelines.

In production systems, these models are typically called as part of a processing pipeline. For example, an image uploaded to a photo editor triggers a mask generation API to extract the foreground, which is then composited onto a new background. Variants of the Segment Anything Model (SAM), such as facebook/sam3, are commonly used for interactive segmentation where a user provides a point or bounding box prompt.

• Size/quality/speed trade-off: Larger model variants (e.g., SAM-huge) achieve higher segmentation accuracy and finer detail but require more GPU memory and time per inference. Smaller variants run faster and cost less per call but may miss fine edges or confuse similar objects. Choose based on your latency budget and precision requirements.

For most call volumes under tens of millions per month, using a hosted API eliminates the overhead of managing GPU servers, handling autoscaling, and paying for idle capacity, making it more cost-effective than self-hosting.
