SAM 3 is a unified foundation model for promptable segmentation in images and videos. It can detect, segment, and track objects using text or visual prompts such as points, boxes, and masks. Compared to its predecessor SAM 2, SAM 3 introduces the ability to exhaustively segment all instances of an open-vocabulary concept specified by a short text phrase or exemplars. Unlike prior work, SAM 3 can handle a vastly larger set of open-vocabulary prompts. It achieves 75-80% of human performance on our new SA-CO benchmark which contains 270K unique concepts, over 50 times more than existing benchmarks.

SAM3 - Promptable Concept Segmentation (PCS) for Images

SAM3 performs Promptable Concept Segmentation (PCS) on images, taking text and/or image exemplars as prompts and returning segmentation masks for all matching object instances in the image.

Text-Only Prompts

python

>>> from transformers import Sam3Processor, Sam3Model
>>> import torch
>>> from PIL import Image
>>> import requests

>>> device = "cuda" if torch.cuda.is_available() else "cpu"

>>> model = Sam3Model.from_pretrained("facebook/sam3").to(device)
>>> processor = Sam3Processor.from_pretrained("facebook/sam3")

>>> # Load image
>>> image_url = "http://images.cocodataset.org/val2017/000000077595.jpg"
>>> image = Image.open(requests.get(image_url, stream=True).raw).convert("RGB")

>>> # Segment using text prompt
>>> inputs = processor(images=image, text="ear", return_tensors="pt").to(device)

>>> with torch.no_grad():
...     outputs = model(**inputs)

>>> # Post-process results
>>> results = processor.post_process_instance_segmentation(
...     outputs,
...     threshold=0.5,
...     mask_threshold=0.5,
...     target_sizes=inputs.get("original_sizes").tolist()
... )[0]

>>> print(f"Found {len(results['masks'])} objects")
>>> # Results contain:
>>> # - masks: Binary masks resized to original image size
>>> # - boxes: Bounding boxes in absolute pixel coordinates (xyxy format)
>>> # - scores: Confidence scores

You can display masks using a simple helper like the following:

python

import numpy as np
import matplotlib

def overlay_masks(image, masks):
    image = image.convert("RGBA")
    masks = 255 * masks.cpu().numpy().astype(np.uint8)
    
    n_masks = masks.shape[0]
    cmap = matplotlib.colormaps.get_cmap("rainbow").resampled(n_masks)
    colors = [
        tuple(int(c * 255) for c in cmap(i)[:3])
        for i in range(n_masks)
    ]

    for mask, color in zip(masks, colors):
        mask = Image.fromarray(mask)
        overlay = Image.new("RGBA", image.size, color + (0,))
        alpha = mask.point(lambda v: int(v * 0.5))
        overlay.putalpha(alpha)
        image = Image.alpha_composite(image, overlay)
    return image

Then you can save the resulting composite image or display it in a notebook:

>>> overlay_masks(image, results["masks"])

Single Bounding Box Prompt

Segment objects using a bounding box:

python

>>> # Box in xyxy format: [x1, y1, x2, y2] in pixel coordinates
>>> # Example: laptop region
>>> box_xyxy = [100, 150, 500, 450]
>>> input_boxes = [[box_xyxy]]  # [batch, num_boxes, 4]
>>> input_boxes_labels = [[1]]  # 1 = positive box

>>> inputs = processor(
...     images=image,
...     input_boxes=input_boxes,
...     input_boxes_labels=input_boxes_labels,
...     return_tensors="pt"
... ).to(device)

>>> with torch.no_grad():
...     outputs = model(**inputs)

>>> # Post-process results
>>> results = processor.post_process_instance_segmentation(
...     outputs,
...     threshold=0.5,
...     mask_threshold=0.5,
...     target_sizes=inputs.get("original_sizes").tolist()
... )[0]

Multiple Box Prompts (Positive and Negative)

Use multiple boxes with positive and negative labels to refine the concept:

python

>>> # Load kitchen image
>>> kitchen_url = "http://images.cocodataset.org/val2017/000000136466.jpg"
>>> kitchen_image = Image.open(requests.get(kitchen_url, stream=True).raw).convert("RGB")

>>> # Define two positive boxes (e.g., dial and button on oven)
>>> # Boxes are in xyxy format [x1, y1, x2, y2] in pixel coordinates
>>> box1_xyxy = [59, 144, 76, 163]  # Dial box
>>> box2_xyxy = [87, 148, 104, 159]  # Button box
>>> input_boxes = [[box1_xyxy, box2_xyxy]]
>>> input_boxes_labels = [[1, 1]]  # Both positive

>>> inputs = processor(
...     images=kitchen_image,
...     input_boxes=input_boxes,
...     input_boxes_labels=input_boxes_labels,
...     return_tensors="pt"
... ).to(device)

>>> with torch.no_grad():
...     outputs = model(**inputs)

>>> # Post-process results
>>> results = processor.post_process_instance_segmentation(
...     outputs,
...     threshold=0.5,
...     mask_threshold=0.5,
...     target_sizes=inputs.get("original_sizes").tolist()
... )[0]
>>> overlay_masks(kitchen_image, results["masks"])

Combined Prompts (Text + Negative Box)

Use text prompts with negative visual prompts to refine the concept:

python

>>> # Segment "handle" but exclude the oven handle using a negative box
>>> text = "handle"
>>> # Negative box covering oven handle area (xyxy): [40, 183, 318, 204]
>>> oven_handle_box = [40, 183, 318, 204]
>>> input_boxes = [[oven_handle_box]]

>>> inputs = processor(
...     images=kitchen_image,
...     text=text,
...     input_boxes=input_boxes,
...     input_boxes_labels=[[0]],  # 0 = negative (exclude this region)
...     return_tensors="pt"
... ).to(device)

>>> with torch.no_grad():
...     outputs = model(**inputs)

>>> # Post-process results
>>> results = processor.post_process_instance_segmentation(
...     outputs,
...     threshold=0.5,
...     mask_threshold=0.5,
...     target_sizes=inputs.get("original_sizes").tolist()
... )[0]
>>> # This will segment pot handles but exclude the oven handle

Batched Inference with Text Prompts

Process multiple images with different text prompts by batch:

python

>>> cat_url = "http://images.cocodataset.org/val2017/000000077595.jpg"
>>> kitchen_url = "http://images.cocodataset.org/val2017/000000136466.jpg"
>>> images = [
...     Image.open(requests.get(cat_url, stream=True).raw).convert("RGB"),
...     Image.open(requests.get(kitchen_url, stream=True).raw).convert("RGB")
... ]

>>> text_prompts = ["ear", "dial"]

>>> inputs = processor(images=images, text=text_prompts, return_tensors="pt").to(device)

>>> with torch.no_grad():
...     outputs = model(**inputs)

>>> # Post-process results for both images
>>> results = processor.post_process_instance_segmentation(
...     outputs,
...     threshold=0.5,
...     mask_threshold=0.5,
...     target_sizes=inputs.get("original_sizes").tolist()
... )

>>> print(f"Image 1: {len(results[0]['masks'])} objects found")
>>> print(f"Image 2: {len(results[1]['masks'])} objects found")

Batched Mixed Prompts

Use different prompt types for different images in the same batch:

python

>>> # Image 1: text prompt "laptop"
>>> # Image 2: visual prompt (dial box)
>>> box2_xyxy = [59, 144, 76, 163]

>>> inputs = processor(
...     images=images,
...     text=["laptop", None],  # Only first image has text
...     input_boxes=[None, [box2_xyxy]],  # Only second image has box
...     input_boxes_labels=[None, [1]],  # Positive box for second image
...     return_tensors="pt"
... ).to(device)

>>> with torch.no_grad():
...     outputs = model(**inputs)

>>> # Post-process results for both images
>>> results = processor.post_process_instance_segmentation(
...     outputs,
...     threshold=0.5,
...     mask_threshold=0.5,
...     target_sizes=inputs.get("original_sizes").tolist()
... )
>>> # Both images processed in single forward pass

Semantic Segmentation Output

SAM3 also provides semantic segmentation alongside instance masks:

python

>>> inputs = processor(images=image, text="ear", return_tensors="pt").to(device)

>>> with torch.no_grad():
...     outputs = model(**inputs)

>>> # Instance segmentation masks
>>> instance_masks = torch.sigmoid(outputs.pred_masks)  # [batch, num_queries, H, W]

>>> # Semantic segmentation (single channel)
>>> semantic_seg = outputs.semantic_seg  # [batch, 1, H, W]

>>> print(f"Instance masks: {instance_masks.shape}")
>>> print(f"Semantic segmentation: {semantic_seg.shape}")

SAM3 Video - Promptable Concept Segmentation (PCS) for Videos

SAM3 Video performs Promptable Concept Segmentation (PCS) on videos, taking text as prompts and detecting and tracking all matching object instances across video frames.

Pre-loaded Video Inference

Process a video with all frames already available using text prompts:

python

>>> from transformers import Sam3VideoModel, Sam3VideoProcessor
>>> from accelerate import Accelerator
>>> import torch

>>> device = Accelerator().device
>>> model = Sam3VideoModel.from_pretrained("facebook/sam3").to(device, dtype=torch.bfloat16)
>>> processor = Sam3VideoProcessor.from_pretrained("facebook/sam3")

>>> # Load video frames
>>> from transformers.video_utils import load_video
>>> video_url = "https://huggingface.co/datasets/hf-internal-testing/sam2-fixtures/resolve/main/bedroom.mp4"
>>> video_frames, _ = load_video(video_url)

>>> # Initialize video inference session
>>> inference_session = processor.init_video_session(
...     video=video_frames,
...     inference_device=device,
...     processing_device="cpu",
...     video_storage_device="cpu",
...     dtype=torch.bfloat16,
... )

>>> # Add text prompt to detect and track objects
>>> text = "person"
>>> inference_session = processor.add_text_prompt(
...     inference_session=inference_session,
...     text=text,
... )

>>> # Process all frames in the video
>>> outputs_per_frame = {}
>>> for model_outputs in model.propagate_in_video_iterator(
...     inference_session=inference_session, max_frame_num_to_track=50
... ):
...     processed_outputs = processor.postprocess_outputs(inference_session, model_outputs)
...     outputs_per_frame[model_outputs.frame_idx] = processed_outputs

>>> print(f"Processed {len(outputs_per_frame)} frames")
Processed 51 frames

>>> # Access results for a specific frame
>>> frame_0_outputs = outputs_per_frame[0]
>>> print(f"Detected {len(frame_0_outputs['object_ids'])} objects")
>>> print(f"Object IDs: {frame_0_outputs['object_ids'].tolist()}")
>>> print(f"Scores: {frame_0_outputs['scores'].tolist()}")
>>> print(f"Boxes shape (XYXY format, absolute coordinates): {frame_0_outputs['boxes'].shape}")
>>> print(f"Masks shape: {frame_0_outputs['masks'].shape}")

Streaming Video Inference

For real-time applications, the Transformers implementation of SAM3 Video supports processing video frames as they arrive:

python

>>> # Initialize session for streaming
>>> streaming_inference_session = processor.init_video_session(
...     inference_device=device,
...     processing_device="cpu",
...     video_storage_device="cpu",
...     dtype=torch.bfloat16,
... )

>>> # Add text prompt
>>> text = "person"
>>> streaming_inference_session = processor.add_text_prompt(
...     inference_session=streaming_inference_session,
...     text=text,
... )

>>> # Process frames one by one (streaming mode)
>>> streaming_outputs_per_frame = {}
>>> for frame_idx, frame in enumerate(video_frames[:50]):  # Process first 50 frames
...     # First, process the frame using the processor
...     inputs = processor(images=frame, device=device, return_tensors="pt")
...
...     # Process frame using streaming inference - pass the processed pixel_values
...     model_outputs = model(
...         inference_session=streaming_inference_session,
...         frame=inputs.pixel_values[0],  # Provide processed frame - this enables streaming mode
...         reverse=False,
...     )
...
...     # Post-process outputs with original_sizes for proper resolution handling
...     processed_outputs = processor.postprocess_outputs(
...         streaming_inference_session,
...         model_outputs,
...         original_sizes=inputs.original_sizes,  # Required for streaming inference
...     )
...     streaming_outputs_per_frame[frame_idx] = processed_outputs
...
...     if (frame_idx + 1) % 10 == 0:
...         print(f"Processed {frame_idx + 1} frames...")

>>> print(f"✓ Streaming inference complete! Processed {len(streaming_outputs_per_frame)} frames")
✓ Streaming inference complete! Processed 50 frames

>>> # Access results
>>> frame_0_outputs = streaming_outputs_per_frame[0]
>>> print(f"Detected {len(frame_0_outputs['object_ids'])} objects in first frame")
>>> print(f"Boxes are in XYXY format (absolute pixel coordinates): {frame_0_outputs['boxes'].shape}")
>>> print(f"Masks are at original video resolution: {frame_0_outputs['masks'].shape}")

⚠️ **Note on Streaming Inference Quality**: Streaming inference disables hotstart heuristics that remove unmatched and duplicate objects, as these require access to future frames to make informed decisions. This may result in more false positive detections and duplicate object tracks compared to pre-loaded video inference. For best results, use pre-loaded video inference when all frames are available.
