Slot-count scaling sweep arm: 8-token Markovian Thinking tail, math-only training.

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: slot-count scaling figure (N=8 Markovian)
• —Carry channel: discrete Markovian-Thinking tail (channel_mode=tail, num_registers=0, tail_length=8)
• —Base model: GSAI-ML/LLaDA-8B-Base
• —Training data: OpenMathInstruct-2 subset of mix60k (~30K math traces, oci_python excluded)
• —Training config: `SFT/amlt/chunked_sft_omi30k_scaling_round2_bonete54.yaml`
• —Chunk size: C = 128 tokens
• —Prompt dropout rate (Bernoulli per-trace CSG mask): 0.0
• —Date uploaded: 2026-06-13

How to load

from transformers import AutoModel, AutoTokenizer
model = AutoModel.from_pretrained("albertge/llada-8b-dllm-registers-omi30k-t8", trust_remote_code=True)
tok = AutoTokenizer.from_pretrained("albertge/llada-8b-dllm-registers-omi30k-t8", 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 0 --channel_mode tail --tail_length 8
