llada-8b-dllm-registers-mix60k-r4t4

LLaDA-8B-Base finetuned with both 4 continuous registers and a 4-token Markovian-Thinking tail as the inter-block carry channel.

This checkpoint is part of the dLLM Registers project — register tokens as a bounded, trained, continuous channel for carrying decoding state across denoising windows in diffusion language models.

• —Paper section: tab:main_triad (main triad, LLaDA hybrid arm)
• —Carry channel: hybrid registers + Markovian tail (channel_mode=hybrid, num_registers=4, tail_length=4)
• —Base model: GSAI-ML/LLaDA-8B-Base
• —Training data: mix60k (OpenMathInstruct-2 + OpenCodeInstruct, 60K examples)
• —Training config: `SFT/amlt/chunked_sft_mix60k_c128_llada_noresid_bonete54.yaml`
• —Chunk size: C = 128 tokens
• —Prompt dropout rate (Bernoulli per-trace CSG mask): 0.3

How to load

from transformers import AutoModel, AutoTokenizer
model = AutoModel.from_pretrained("albertge/llada-8b-dllm-registers-mix60k-r4t4", trust_remote_code=True)
tok = AutoTokenizer.from_pretrained("albertge/llada-8b-dllm-registers-mix60k-r4t4", trust_remote_code=True)

To use the carry channel correctly at inference, see the evaluator at `eval/eval.py` and the wrapper `eval/run_mix60k_full_eval.sh`. Key flags for this checkpoint: --num_registers 4 --channel_mode hybrid --tail_length 4 --usemasktokenforregisters
