Meet the Sparse Processing Unit (SPU) chip and AI developer platform: Unlocking the Next Generation of Smart Glasses

Today's smart glasses have failed to achieve mass adoption due to three key problems: unattractive bulky designs, poor battery life, and unreliable voice interfaces with low audio quality.

The Sparse Processing Unit (SPU) chip and AI developer platform addresses all three. It enables smart glasses that are light and stylish, last all day on a single charge, deliver crystal-clear audio, and unlocks a voice interface that works reliably — even in noisy environments or at low speech volumes. The SPU achieves this through ultra-low power consumption and latency, making larger on-device AI models practical for the first time. With 10x model compression efficiency, the SPU delivers outstanding performance at 100x lower power within existing memory budgets — unlocking use cases previously out of reach.

This talk provides an overview of the SPU chip and developer platform and the unique capabilities it brings to smart glasses.
