Paper: Register Tokens for Bounded-State Reasoning in Diffusion Language Models
Dream-v0-Base-7B finetuned with 4 continuous register slots 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, Dream registers arm)
- Carry channel: continuous register tokens (
channel_mode=registers,num_registers=4,tail_length=0) - Base model: Dream-org/Dream-v0-Base-7B
- Training data: mix60k (OpenMathInstruct-2 + OpenCodeInstruct, 60K examples)
- Training config:
SFT/amlt/chunked_sft_mix60k_c128_dream_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/dream-7b-dllm-registers-mix60k-r4", trust_remote_code=True)
tok = AutoTokenizer.from_pretrained("albertge/dream-7b-dllm-registers-mix60k-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.
Key flags for this checkpoint:
