llada-8b-dllm-registers-code64-codetags-t4

Continued chunked SFT from albertge/llada-8b-dllm-registers-mix60k-t4 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 (Markovian Thinking arm)
• Carry channel: discrete Markovian-Thinking tail (channel_mode=tail, num_registers=0, tail_length=4)
• 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): 0.0
• Date uploaded: 2026-06-13

How to load

from transformers import AutoModel, AutoTokenizer
model = AutoModel.from_pretrained("albertge/llada-8b-dllm-registers-code64-codetags-t4", trust_remote_code=True)
tok = AutoTokenizer.from_pretrained("albertge/llada-8b-dllm-registers-code64-codetags-t4", 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 4
