## Choose when

### Choose segment-anything if…

- segment-anything is primarily Jupyter Notebook; ultralytics is Python.
- License: segment-anything is Apache-2.0, ultralytics is AGPL-3.0.
- Requirements: Min 8 GB RAM; Requires Python >=3.8, PyTorch >=1.7 with CUDA recommended for faster performance; Optional dependencies such as OpenCV and ONNX may further enhance functionality but are not always necessary for basic use..
- Ultralytics focuses on comprehensive computer vision tasks, including segmentation. Segment Anything Model could be used as a specialized tool for segmentation tasks within the broader Ultralytics suite.
- Tags unique to segment-anything: image-processing, jupyter-notebook, pytorch, segmentation.
- Also covers Inference & Serving.
- When you need precise segmentation in images with varied objects or regions, as SAM provides high-quality mask generation from prompts.

### Choose ultralytics if…

- ultralytics is primarily Python; segment-anything is Jupyter Notebook.
- License: ultralytics is AGPL-3.0, segment-anything is Apache-2.0.
- Ultralytics focuses on comprehensive computer vision tasks, including segmentation. Segment Anything Model could be used as a specialized tool for segmentation tasks within the broader Ultralytics suite.
- Tags unique to ultralytics: computer-vision, deep-learning, image-classification, instance-segmentation.
- Also covers Computer Vision.
- When precision in real-time object detection and segmentation across multiple domains (e.g., robotics, surveillance) is needed.

## When NOT to use segment-anything

- Avoid using SAM if your project's constraints specifically require real-time performance since running inference demands significant computational resources.
- Do not choose this tool when a lightweight or resource-efficient solution is needed, as it relies on heavyweight pre-trained models that may be unsuitable for devices with limited computing power.

## When NOT to use ultralytics

- If a project requires proprietary modifications or integrations where source code contributions must be tightly controlled, as the AGPL-3.0 would require sharing modified versions of Ultralytics.
- When deployment scenarios strictly limit the use of open-source software due to compliance or security policies that might conflict with AGPL licensing.
