Horizon Robotics

Horizon Robotics (Hong Kong Stock Exchange: 9660.HK) is a Chinese provider of smart-driving computing solutions, founded in 2015, that designs the Journey (征程) family of automotive AI processors around its proprietary BPU (Brain Processing Unit) architecture and pairs them with a full software stack — Horizon Mono ADAS, Horizon SuperDrive assisted driving, TogetheROS, Matrix, QoHo and AIDI. Its developer-facing surface is not a hosted web API but a toolchain: OpenExplorer (OE), the model compilation, quantization and deployment kit built around HBDK, HMCT, the Horizon PyTorch Plugin, horizon_tc_ui and the UCP on-board runtime, documented at developer.horizon.auto and doc.oe.horizon.auto. Horizon publishes two genuine agent surfaces on top of that toolchain: a live, unauthenticated remote Model Context Protocol server at mcp.oe.horizon.auto that exposes semantic code and documentation retrieval, and OE-Skills, an Apache-2.0 pack of 37 structured Agent Skills for Claude Code, Codex and Cursor that drive HBDK compilation, PTQ/QAT quantization, UCP on-board inference and LLM compression.

Horizon Robotics publishes 1 API on the APIs.io network. Tagged areas include Company, Artificial Intelligence, Automotive, Autonomous Driving, and Semiconductors.

Horizon Robotics’ developer surface includes documentation, engineering blog, support, signup flow, CLI, authentication, changelog, and 20 more developer resources.
