## News

- **2026-09**: Accepted at **NeurIPS 2026**.

Public adapter release for **dLLM PRM Gap**. a C3 control checkpoint with the stated attention/readout protocol and seed.

> This repository contains only trainable adapter parameters and the reward head. It does not include the base model. The release configuration is recorded in `config.json`; the arXiv paper defines the release scope and citation.

## Files

- `adapter.safetensors` — compact adapter weights
- `config.json` — public base-model id, architecture, and provenance

## Load

```python
from huggingface_hub import snapshot_download
from prm.checkpointing import load_diffusion_prm

path = snapshot_download("YanZhanPKU/dLLM-PRM-Gap-c3a-causal-lasttoken-dream7b-s43")
model, report = load_diffusion_prm(
    checkpoint=path,
    model_path="Dream-org/Dream-v0-Instruct-7B",
    local_files_only=False,
)
```

**Role:** C3A causal last-token ORM-protocol control.
