llada-8b-dllm-registers-code64-codetags-r4
Continued chunked SFT from albertge/llada-8b-dllm-registers-mix60k-r4 on the code-only split of mix60k at C=64 with -delimited targets.
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:code_chunk64 (registers arm)
- Carry channel: continuous register tokens (
channel_mode=registers,num_registers=4,tail_length=0) - Base model: GSAI-ML/LLaDA-8B-Base
- Training data: OpenCodeInstruct subset of mix60k (~30K traces), ... targets
- Training config:
SFT/amlt/chunked_sft_mix60k_code64_code_tags_continuation_bonete54.yaml - Chunk size: C = 64 tokens
- Prompt dropout rate (Bernoulli per-trace CSG mask): 0.7

How to load
from transformers import AutoModel, AutoTokenizer
model = AutoModel.from_pretrained("albertge/llada-8b-dllm-registers-code64-codetags-r4", trust_remote_code=True)
tok = AutoTokenizer.from_pretrained("albertge/llada-8b-dllm-registers-code64-codetags-r4", 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.
