Run time and cost

This model costs approximately $0.024 to run on Replicate, or 41 runs per $1, but this varies depending on your inputs. It is also open source and you can run it on your own computer with Docker.

This model runs on Nvidia L40S GPU hardware. Predictions typically complete within 25 seconds. The predict time for this model varies significantly based on the inputs.

✨SAM 2: Segment Anything v2 for Images 🎥

NOTE: Note: Currently, we only support image inputs (not video yet) and exclusively offer the large variant of the model.

About

Implementation of SAM 2, a model for segmenting objects in images and videos using various prompts.

Limitations

  • Performance may vary depending on image/video quality and complexity.
  • Very fast or complex motions in videos might be challenging.
  • Higher resolutions provide more detail but require more processing time.

SAM 2 is a 🔥 model developed by Meta AI Research. It excels at segmenting objects in both images and videos with various types of prompts.

Core Model

model architecture
An overview of the SAM 2 framework.

SAM 2 uses a transformer architecture with streaming memory for real-time video processing. It builds on the original SAM model, extending its capabilities to video.

Safety

⚠️ Users should be aware of potential ethical implications: - Ensure you have the right to use input images and videos, especially those featuring identifiable individuals. - Be responsible about generated content to avoid potential misuse. - Be cautious about using copyrighted material as inputs without permission.
