# GLM-5.2 FP8 DFLASH v2

## Overview

This is a DFLASH speculative draft model for GLM-5.2 FP8 serving. The checkpoint
uses DFLASH block size 12 and is intended to be loaded as the draft model in
SGLang speculative decoding.

This model is fine-tuned on top of `SubconsciousDev/glm-5.2-fp8-dflash-v1`
using `SubconsciousDev/Subconscious-Dflash-Training-Dataset-mix-glm52-25k`.

## SGLang Usage

Add these arguments to the SGLang launch command:

```bash
--speculative-algorithm DFLASH \
--speculative-draft-model-path SubconsciousDev/glm-5.2-fp8-dflash-v2 \
--speculative-num-draft-tokens 12 \
--speculative-draft-kv-cache-dtype bfloat16
```
