374M byte-level models from Dynamic Multi-Byte Prediction With Hierarchical Language Models — arxiv.org/abs/2608.15454
Note LCA-MBP, the paper's method: multi-byte prediction head with Latent Causal Attention, ~3.3 bytes/patch.
Note LCA-MBP after Tulu SFT. The instruction-following model behind the speculative decoding results.
Note Hierarchical byte baseline at the same segmentation rate, without the MBP head.
Note The no-MBP baseline after Tulu SFT.
Note Flat 22-layer byte transformer: no segmentation, one forward pass per byte.
Note The flat byte baseline after Tulu SFT.
