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.

Full-lifecycle RFP intelligence with deterministic accuracy and grounded AI
Pull opportunities from SAM.gov, eBuy, Find a Tender, and other sources, then score contract fit and run AI win-theme and past-performance analysis.
A rules-based engine shreds requirements, builds compliance matrices, flags liability and risk language through dictionaries and watchwords, and compares versions with 100% repeatable, audit-ready results.
A Prompt Library and approved Collections give teams a running start on competitive intel, win themes, and past performance, with every answer grounded in approved content and cited to source.
Customizable Kanban stages, tasks, reviewers, and comments keep proposal work moving from initiation through red team to submission on one source of truth.
