Summary
Local AI inference has improved 18x in accuracy per joule over 16 months, driven by a 5.9x gain from hardware advances and a 3x gain from model efficiency improvements. This quantifies the rapid convergence of on-device and cloud AI capabilities, highlighting that the gap is closing faster than most benchmarks have captured.
Why it matters
- 18x accuracy-per-joule gain in 16 months (5.9x hardware + 3x model) quantifies how fast local inference is catching cloud-level capability.
- The hardware and model gains are roughly multiplicative, suggesting both tracks compound independently — meaning the trend may continue.
- The hybrid local/cloud inference framing signals a strategic shift: workloads once assumed to require cloud compute are now viable on-device.
