Classifies images as safe or unsafe for work using a timm-based vision transformer backbone (384-dimensional embedding space) fine-tuned on NSFW/SFW datasets. The model encodes images into a learned embedding space where unsafe content clusters distinctly from safe content, enabling binary or multi-class classification through a trained classification head. Uses safetensors format for efficient model serialization and loading.
Unique: Uses timm vision transformer backbone with 384-dimensional embedding space (vs. ResNet-50 or EfficientNet baselines), enabling efficient batch inference and downstream embedding-space operations like clustering or similarity search. Serialized in safetensors format for faster, safer model loading compared to pickle-based PyTorch checkpoints.
vs alternatives: Faster inference than proprietary APIs (Perspective API, AWS Rekognition) due to local execution, and more transparent than black-box commercial models, though may require fine-tuning for domain-specific content policies.
Processes multiple images in parallel, extracting both classification predictions and 384-dimensional embeddings for each image in a single forward pass. Supports batching via PyTorch DataLoader or manual batch stacking, enabling efficient throughput for large-scale content moderation workflows. Embeddings can be persisted to vector databases for downstream similarity-based filtering or clustering of unsafe content patterns.
Unique: Extracts both classification predictions and embeddings in a single forward pass, allowing downstream vector-space operations (clustering, similarity search) without re-running inference. Supports arbitrary batch sizes via PyTorch's flexible tensor operations, enabling memory-efficient processing on constrained hardware.
vs alternatives: More efficient than calling per-image classification APIs (e.g., AWS Rekognition) for large batches, and provides embeddings for free, enabling downstream similarity-based filtering that proprietary APIs charge separately for.
Performs single-image NSFW classification with minimal latency suitable for synchronous request-response workflows (e.g., API endpoints, chat applications). Uses optimized inference paths via ONNX export or TorchScript compilation to reduce overhead. Can be deployed as a microservice or embedded in application servers for immediate safety feedback on user uploads.
Unique: Optimized for single-image inference with minimal preprocessing overhead. Can be compiled to ONNX or TorchScript for deployment on CPU-only or edge devices without Python runtime, enabling sub-100ms latency on modern GPUs.
vs alternatives: Faster than cloud-based moderation APIs (Perspective, AWS Rekognition) due to local execution and no network round-trip, and more cost-effective for high-volume inference since there are no per-request charges.
Leverages the pre-trained vision transformer backbone and 384-dimensional embedding space as a feature extractor for custom NSFW classification tasks. Enables fine-tuning on domain-specific datasets (e.g., medical imagery, artwork, anime) by replacing or retraining the classification head while freezing or partially unfreezing the backbone. Uses standard PyTorch training loops with cross-entropy loss and gradient descent optimization.
Unique: Provides a pre-trained 384-dimensional embedding space that captures generic NSFW patterns, enabling efficient transfer learning with smaller labeled datasets. Supports both linear probe (frozen backbone) and full fine-tuning strategies, allowing trade-offs between data efficiency and model capacity.
vs alternatives: More data-efficient than training from scratch due to pre-trained backbone, and more flexible than proprietary APIs which cannot be customized for domain-specific policies or edge cases.
Extracts 384-dimensional embeddings for images and enables vector similarity search to find visually similar unsafe content. Embeddings can be indexed in vector databases (Pinecone, Weaviate, Milvus) or used with approximate nearest neighbor (ANN) algorithms (FAISS, Annoy) for fast retrieval. Enables clustering of unsafe content patterns without re-running classification on every image.
Unique: Leverages the 384-dimensional embedding space to enable efficient similarity search without re-running classification. Supports both local ANN algorithms (FAISS) and managed vector databases, enabling scalability from small datasets to billions of images.

Provides keypoint annotations for all people in images using a standardized 17-joint skeleton model (head, shoulders, elbows, wrists, hips, knees, ankles) with (x, y, visibility) tuples per joint. Visibility flag indicates whether keypoint is annotated (1), occluded (0), or outside image bounds (0). Keypoints are linked to parent person instances via instance ID, enabling pose estimation evaluation at both individual and crowd-level scales. Annotations follow COCO Keypoints task specification with consistent coordinate system across all 330K images.
Unique: Standardized 17-joint skeleton with explicit visibility flags enables robust evaluation of pose estimation under occlusion; linked to instance segmentation masks allows joint-level accuracy analysis within person bounding boxes
