# FoxlightAI/qwen3-5-2b-base-mtp

This repository contains an **MTP speculative-decoding sidecar** derived from [`Qwen/Qwen3.5-2B-Base`](https://huggingface.co/Qwen/Qwen3.5-2B-Base). It is **not a standalone model** — it provides the multi-token-prediction heads used by [Skulk](https://github.com/Foxlight-Foundation/Skulk) to speculatively decode for the target model **`Qwen/Qwen3.5-2B-Base`**. The heads ship at full precision (**bf16, unquantized**) — they are the speculative drafter, where precision drives draft acceptance — so there is **one sidecar per base model** and it serves **every quantization** of the target.

## Usage

Skulk loads this sidecar (`mtp.safetensors`) alongside the target model to enable MTP speculative decoding. It is referenced from the Skulk Weights Publisher catalog and fetched automatically by the Skulk shard downloader; it is not intended to be loaded standalone.
