Here we compare Meta's smallest SAM model, SAM-b, with Ultralytics smallest segmentation model, [YOLOv8n-seg](../tasks/segment.md):
| Model | Size<br><sup>(MB)</sup> | Parameters<br><sup>(M)</sup> | Speed (CPU)<br><sup>(ms/im)</sup> |
| ---------------------------------------------- | ----------------------- | ---------------------------- | --------------------------------- |
| Meta SAM-b | 358 | 94.7 | 51096 |
| [MobileSAM](mobile-sam.md) | 40.7 | 10.1 | 46122 |
| [FastSAM-s](fast-sam.md) with YOLOv8 backbone | 23.7 | 11.8 | 115 |
| Ultralytics [YOLOv8n-seg](../tasks/segment.md) | **6.7** (53.4x smaller) | **3.4** (27.9x less) | **59** (866x faster) |

| [MobileSAM](mobile-sam.md) | 40.7 | 10.1 | 46122 |
| [FastSAM-s](fast-sam.md) with YOLOv8 [backbone](https://www.ultralytics.com/glossary/backbone) | 23.7 | 11.8 | 115 |
| Ultralytics [YOLOv8n-seg](../tasks/segment.md) | **6.7** (53.4x smaller) | **3.4** (27.9x less) | **59** (866x faster) |
This comparison shows the order-of-magnitude differences in the model sizes and speeds between models. Whereas SAM presents unique capabilities for automatic segmenting, it is not a direct competitor to YOLOv8 segment models, which are smaller, faster and more efficient.
