Adaptive Precision Embedding Quantization

val_bpb: 1.1217 (4-seed mean) | 15.8 MB | 8×H100 SXM

Checklist

  • Artifact < 16,000,000 bytes (all 4 seeds)
  • Training < 600s, eval < 600s
  • Causal sliding-window evaluation (stride=64)

See README.md for full details

Key Innovation

Top 100 tokens cover 53% of all text. Instead of uniform int6 quantization, this applies:

  • Top 100 tokens → int8 (higher precision)
  • Remaining 924 tokens → int6 (standard precision)

Frequent tokens deserve more precision because their errors compound across the entire dataset.
