Tier IV released five open-source end-to-end autonomous driving AI models. The Tokyo-based company leads development of Autoware, an open-source autonomous driving software platform. The models range from 16 million to 2 billion parameters and support different sensor and map setups.
Model lineup
The lineup includes NVIDIA Alpamayo 2 Edge, AutoE2E, and METEOR. Alpamayo 2 Edge uses camera images only and has 2 billion parameters. AutoE2E and METEOR are lighter and can accept LiDAR or radar inputs.
Company focus
Tier IV is based in Tokyo and is led by CEO Shinpei Kato. The company works with automakers and suppliers on their own autonomous driving development. It also leads the Autoware 2.0 architecture.
How the models work
Several models are already integrated into Autoware. OnePlanner combines perception and planning and produces a six-second driving trajectory. LatentDrive generates a four-second trajectory from camera video without intermediate object detection.
Tier IV plans to improve the models and optimize them for in-vehicle use. It will support automakers and partners through Autoware. The company will present the technology at EdgeTech+ 2026 on November 18, 2026.
