Tesla confirms HW3 FSD upgrades via micro-factories

🔑 Enhanced Key Takeaways

• •The micro-factory initiative, internally dubbed 'Project Retrofit,' aims to decentralize the upgrade process to avoid overwhelming Tesla Service Centers, which have faced significant bottlenecks with previous hardware campaigns.
• •The physical upgrade is necessitated by the transition to 'End-to-End' neural network architectures that exceed the memory and compute bandwidth limitations of the original HW3 FSD computer.
• •Tesla is exploring a tiered upgrade program where owners with active FSD subscriptions may receive priority scheduling or subsidized installation costs compared to one-time purchasers.

🛠️ Technical Deep Dive

• •HW3 (FSD Computer 1) utilizes a custom dual-SoC design with 144 TOPS of neural network performance, which is insufficient for the high-parameter transformer models used in the latest FSD v13+ software stack.
• •The required upgrade involves replacing the existing FSD computer with a new module featuring increased SRAM capacity and higher-bandwidth memory (HBM) to support larger model weights.
• •The micro-factory implementation will utilize automated diagnostic rigs to verify the integrity of the new hardware installation before the vehicle is returned to the customer, ensuring safety-critical compliance.
