Turn OpenAPI and Swagger specs into AI-ready function calls
Ingest standard OpenAPI or Swagger specifications and export function-call parameters ready for AI model tool use.
Generates compact parameter definitions that reduce the context cost of exposing large API surfaces to language models.
Designed to work with popular model endpoints including ChatGPT/OpenAI, Claude, Gemini and Llama family models.
A hosted web service, so teams can convert specs through the browser without maintaining parsing infrastructure.

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.
