TIER IV Details Five Open-Source Models for Autonomous Driving

What happened

TIER IV announced on November 11, 2026, the development and open-source availability of five end-to-end autonomous-driving AI models for Autoware, spanning camera-only systems and configurations that add LiDAR (a sensor that measures distance with laser pulses), radar and high-definition maps. Their end-to-end designs connect perception of the environment with driving-trajectory generation, but the models differ in sensor requirements, planning approach and readiness: some are integrated with Autoware, while vehicle adaptation or integration continues for others.

That architecture combines AI-based and conventional rule-based approaches, adds a flexible indexing scheme for modular software integration and provides a Reference Design framework intended to facilitate commercial adoption across vehicles, applications and operating environments. The lineup gives automakers and technology partners several options for optimizing models and integrating them into vehicle systems.

The lineup comprises NVIDIA Alpamayo 2 Edge, AutoE2E, METEOR, OnePlanner and LatentDrive. NVIDIA is a semiconductor company based in Santa Clara, and its products and services include software.

TIER IV presents the models as concrete technological outcomes for Autoware 2.0 , the next-generation architecture it detailed on November 2, 2026. Different Models for Different Vehicles TIER IV reports that Alpamayo 2 Edge has 2 billion parameters, compared with 34 billion in Alpamayo 2 Super , and operates with only camera images and reasoning to generate driving trajectories.

Its Autoware integration is complete, but TIER IV is still optimizing the model and adapting it to real vehicles. TIER IV puts it at 79.9 million parameters and says it can run on computing platforms beyond NVIDIA hardware, with configurations ranging from cameras alone to systems incorporating LiDAR and radar.
