# Alpamayo 1 (R1) — DFlash draft
**Flash Vision-Language-Action Inference for Autonomous Driving**

[DFlash](https://github.com/z-lab/dflash) draft model for [z-lab/Alpamayo-R1-10B](https://huggingface.co/z-lab/Alpamayo-R1-10B), used by [FlashDrive](https://github.com/z-lab/flashdrive) to accelerate the chain-of-causation reasoning of [Alpamayo 1 (R1)](https://huggingface.co/nvidia/Alpamayo-R1-10B).
DFlash (ICML 2026) uses a lightweight block-diffusion draft to propose several tokens in parallel; the target verifies each block in a single forward, preserving its output distribution. This draft is a 2-layer Qwen3-style network (block size 8) conditioned on target hidden states from layers 24/30/31/32/34. The repository also ships `mask_embedding.pt`, the trained mask-token embedding FlashDrive appends to the target's embedding table.
> [!NOTE]
> **Not a standalone language model.** FlashDrive attaches it to the [base checkpoint](https://huggingface.co/z-lab/Alpamayo-R1-10B) automatically — you do not load this repository directly.
## Usage
```python
import flashdrive
# from_pretrained fetches this -DFlash checkpoint automatically
model = flashdrive.from_pretrained("z-lab/Alpamayo-R1-10B")
```
See the [base model card](https://huggingface.co/z-lab/Alpamayo-R1-10B) and the [FlashDrive repository](https://github.com/z-lab/flashdrive) for the full pipeline.
