💡Math framework perfectly matches LLMs to AV chips, slashing costs & adaptation time

⚡ 30-Second TL;DR

What Changed

Introduces 'end-side LLM soft-hard co-design law' using loss scaling and Roofline modeling

Why It Matters

This enables AV firms to build scenario-optimal chips efficiently, accelerating edge AI deployment and challenging Nvidia dominance. It provides a replicable blueprint for the industry.

What To Do Next

Implement PLAS-like Roofline modeling to tune your edge LLM for Orin hardware constraints.

🔑 Enhanced Key Takeaways

  • Li Auto mass-produced the first vehicles globally equipped with VLA models via the i8 launch in August 2025, expanding to the entire AD Max lineup by September 2025[1].
  • Li Auto restructured its autonomous driving division into 11 sub-departments in 2025, subdividing algorithms into basic models, VLA models, and model engineering to support VLA as its core technology route[1].
  • In March 2025, Li Auto unveiled the MindVLA architecture, a dual-system integrating end-to-end learning and Vision-Language Models, described by CEO Li Xiang as a 'robot large model'[2].

🔮 Future ImplicationsAI analysis grounded in cited sources

Li Auto's PLAS framework will enable deployment of optimized VLA models on next-gen chips like Mach 100 by late 2026
The framework targets the new L9 model with Mach 100 chip, aligning with Li Auto's 2026 growth plans and L9 updates featuring high computing power up to 2560 TOPS[6].
PLAS co-design will face regulatory hurdles from China's July 2027 Level 3 standards requiring minimal risk maneuvers and data recorders
New MIIT rules mandate advanced safety features for Level 3 systems, potentially impacting VLA deployment timelines in Li Auto vehicles[3].
