Hailo

HailoRT

HailoRT is Hailo's production runtime library for the Hailo-8, Hailo-10 and Hailo-15 device families. It is a host-side, user-space C/C++ library with a Python binding (pyHailoRT), a hailortcli command line tool, a GStreamer element (hailonet) and a PCIe kernel driver. It is a local device API rather than a network API — there is no hosted HTTP base URL. The machine-readable contracts it publishes are Protocol Buffers definitions in the hailo-ai/hailort repository: the hRPC client/server request and reply scheme, the GenAI (LLM / VLM / speech / embeddings) request scheme, the HEF compiled-model file format, and the scheduler-monitor and tracer-profiler telemetry schemes.

x-base-url: none
x-base-url-note: Deliberately no baseURL. HailoRT is a host-side library that talks to the accelerator
  over PCIe or USB through a kernel driver. There is no HTTP host to record, and repair-api-bases.py confirmed
  on 2026-08-22 that no source names one. Recorded as absent rather than guessed from the domain.
