val_bpb: 0.82005771 (3-seed mean, seeds 123/999/42)
Artifact size: ~15.99 MB (all 3 runs < 16,000,000 bytes)
Training time: < 600s wall clock (8×H100 SXM)
Combines SP10240 casefold tokenization, Test-Time Training (TTT), GPTQ quantization, and a novel byte-level PPM-D order-5 mixture. The PPM predictor runs causally on Rank 0 after distributed TTT scoring, mixing at token probability level with confidence gating (λ=0.05 when PPM confidence ≥ 0.9).
