AI Analysis

●●●●GemWizardryZero to OneBig Brain

Runs 60GB models on 12GB phones by streaming experts from flash, not RAM.

Strengths
  • 5x memory overcommit achieved while maintaining byte-identical output to full RAM loading
  • Custom expert caching and read/compute overlap engineered for UFS storage constraints
  • Rigorous moe_gates tests verify lossless streaming against resident model baseline
Weaknesses
  • 1.3 tok/s is usable but still too slow for conversational applications
  • Requires specific MoE architecture; dense models cannot use this technique
