ELF-REG demo weights (EMA-0.9999, trimmed)

EMA-0.9999 inference weights for ELF-REG: Scaling Continuous Diffusion Language Models to Reasoning Tasks ( arXiv:2609.29102 ), by Zeyu Michael Li, William Xingxu Chen, Bingshuo Qian, Jiayin Liu and Xiang Cheng (Duke University / Tsinghua University).

These are trimmed mirrors of the official checkpoints published by the first author at zl310/elf-reg — same directory layout, same config.yml files. The originals contain the optimizer state and multiple EMA copies ( 39 GB for the four demo checkpoints); these files keep only ema_params1["0.9999"] , the exact weights the paper's headline evaluation loads ( 10.7 GB total). Content of the EMA state dicts is byte-identical to the originals; nothing was retrained or re-quantized (fp32).

Official code (MIT license): lizeyu090312/scaling_dLM , built on lillian039/ELF (arXiv:2605.10938).
