Multi-modal human interaction datasets for AI model training
Datasets covering image, video, audio, code, text, and conversational interaction for varied model-training needs.
Buyer-scoped datasets with configurable anonymization, filtering, modalities, and delivery formats.
Conversational and text data spanning 100+ languages, including low-resource and underrepresented regions.
Signals that are aligned, annotated, and validated for cross-modality and scientific consistency.

Real-time vision AI models and a full platform to train, annotate, and deploy them
One model family covering detection, instance segmentation, pose estimation, oriented boxes, classification, and tracking, tuned for real-time inference on GPU, CPU, and edge devices.
Label data with SAM-assisted annotation, train on cloud GPUs with AutoTrain, and deploy to managed regions that scale to zero when idle.
Ship trained models to ONNX, TensorRT, CoreML, TFLite, and many other formats for cloud servers, mobile devices, and embedded hardware.
Adopt the open-source AGPL-3.0 release, or purchase an enterprise license to embed YOLO in closed-source products without copyleft obligations.
