GoKawiilTesla renames AI chips 'SI', outlines 6th-gen accelerator with 80x performance gain
Tesla has released an updated AI accelerator roadmap, rebranding its AI3-AI6 chip line as SI4, SI5 and SI6, substituting 'Super Intelligence' for 'Artificial Intelligence' in its naming. The company says its upcoming 6th-generation inference chip will deliver roughly 80 times the compute performance of its current 4th-generation hardware, while its Dojo D3 training chip will move from an SRAM-centric design to a multi-chiplet architecture with stacked HBM memory, replacing the discontinued wafer-scale approach.
GoKawiil's interpretation of the reporting above, not reported fact.
The renaming echoes language reportedly favored by President Trump, and commentators online have speculated Musk may be aligning Tesla's branding with that political framing, though Tesla has not stated this as its reason. The roadmap itself signals Tesla's ambition to compete more directly with Nvidia and other AI chipmakers by scaling up custom silicon for both inference and training workloads. A successful 80x performance leap could meaningfully cut Tesla's reliance on third-party chips for autonomy and robotics projects.
- Tesla rebranded its AI accelerators from AI to SI, following similar branding at SpaceX.
- The 6th-generation SI chip is projected to offer about 80x the compute performance of the current generation.
- Tesla's Dojo D3 training chip will shift to a multi-chiplet design with stacked HBM, dropping wafer-level SRAM integration.
