Rivian Unveils Custom Silicon, Next-Gen Autonomy Platform, and Deep AI Integration at Inaugural Autonomy & AI Day
PALO ALTO, Calif. – December 11, 2025 – Rivian (NASDAQ: RIVN) today announced significant breakthroughs in vertically integrated automotive technology at its first Autonomy & AI Day. During the event at its Palo Alto offices, the company unveiled its proprietary, purpose-built silicon, outlined its roadmap for next-generation vehicle autonomy, and introduced an evolved software architecture underpinned by artificial intelligence (AI).
“I couldn’t be more excited for the work our teams are driving in autonomy and AI. Our updated hardware platform, which includes our in-house 1600 sparse TOPS inference chip, will enable us to achieve dramatic progress in self-driving to ultimately deliver on our goal of delivering L4. This represents an inflection point for the ownership experience – ultimately being able to give customers their time back when in the car,” said Rivian Founder and CEO RJ Scaringe.
Rivian Autonomy Processor and Gen 3 Autonomy Computer
At the core of Rivian’s technology roadmap is the transition to in-house silicon, designed specifically for the vision-centric physical AI. The first generation Rivian Autonomy Processor (RAP1) is a custom 5nm processor that integrates processing and memory onto a single multi-chip module. This architecture delivers advanced levels of efficiency, performance, and Automotive Safety Integrity Level compliance.
RAP1 powers the company’s third-generation Autonomy computer, the Autonomy Compute Module 3 (ACM3). Key specifications of the ACM3 include:
Our Gen 3 Autonomy hardware including ACM3 and LiDAR is currently undergoing validation and we expect it to ship on R2 models starting at the end of 2026.
Rivian Autonomy Platform
Rivian also detailed its software-first approach to autonomy, powered by the Rivian Autonomy Platform and an end-to-end data loop used for training. The company introduced its Large Driving Model (LDM), a foundational autonomous model trained like a Large Language Model (LLM). Utilizing Group-Relative Policy Optimization (GRPO), the LDM will distill superior driving strategies from massive datasets into the vehicle.
Software advancements are coming to the company’s second generation R1 vehicles in the near term with the addition of Universal Hands-Free (UHF), bringing hands-free assisted driving for extended periods to significantly more places.
Rivian also detailed plans to continuously improve the autonomy capabilities of its Gen 2 R1 and future R2 vehicles, with a clear trajectory including point-to-point, eyes off and personal L4.
Rivian Unified Intelligence and Rivian Assistant
Beyond vehicle autonomy, Rivian is harnessing AI across the business with the Rivian Unified Intelligence (RUI). The shared, multi-modal and multi-LLM data foundation is helping the company develop powerful new features, improve service infrastructure, and even power predictive maintenance. The highlight of this new architecture is the Rivian Assistant, a next-generation voice interface launching in early 2026 on Gen 1 and Gen 2 R1 vehicles.
Rivian’s unique, vertically integrated strategy allows the company to rapidly evolve the entire vehicle experience—from user-facing features to foundational technology. In the company’s next stage of growth, integration meets acceleration as this next-generation hardware and software come to market.

RAP1 powers the company’s third-generation Autonomy computer, the Autonomy Compute Module 3 (ACM3). Key specifications of the ACM3 include:
- 1600 sparse INT8 TOPS (Trillion Operations Per Second).
- The processing power of 5 billion pixels per second.
- RAP1 features RivLink, a low latency interconnect technology allowing chips to be connected to multiply processing power, making it inherently extensible.
- RAP1 is enabled by an in-house developed AI compiler and platform software.
