+# OPDLM-0.6B
+
+OPDLM-0.6B is a block diffusion language model (DLM) obtained by post-training an
+autoregressive language model (ARLM) into a diffusion language model via
+**on-policy distillation**. arXiv report: [arxiv.org/abs/2606.06712](https://arxiv.org/abs/2606.06712)
+
+## Highlights
+- **Converted, not pretrained from scratch:** built from a strong ARLM, reusing its prior.
+- **Training-efficient:** orders of magnitude fewer tokens than from-scratch DLM training (same base ARLM).
+- **Inference-efficient:** parallel token decoding via block diffusion.
+
+## Model Details
+- **Developed by:** DIVE Lab, Texas A&M University
+- **Base model:** [Qwen3-0.6B](https://huggingface.co/Qwen/Qwen3-0.6B)
+- **Model type:** Block diffusion language model (decoder-based)
+- **Block size:** 4
+- **Parameters:** ~0.6B
+- **Language:** English
+- **License:** MIT
+
+## Training
+- **Method:** On-policy distillation from a frozen ARLM teacher into a block DLM student.
+- **Conversion budget:** ~<fill in>B tokens
+- **Data:** [opdlm_train_data](https://huggingface.co/datasets/divelab/opdlm_train_data)
