# Speculative Decoding

## :llama:llama.cpp、llama-server における投機的デコーディング

llama.cpp での投機的デコーディングは、次の方法で簡単に有効にできます `llama-cli` および `llama-server` 経由で `--model-draft` 引数。ドラフトモデルが必要であることに注意してください。通常は小さいモデルですが、トークナイザーは同じでなければなりません 

### GLM 4.7 向けの Spec デコーディング

```python
# !pip install huggingface_hub hf_transfer
import os
os.environ["HF_HUB_ENABLE_HF_TRANSFER"] = "0" # 時々レート制限されることがあるため、無効にするには0に設定
from huggingface_hub import snapshot_download
snapshot_download(
    repo_id = "unsloth/GLM-4.7-GGUF",
    local_dir = "unsloth/GLM-4.7-GGUF",
    allow_patterns = ["*UD-Q2_K_XL*"], # 動的2ビットには "*UD-TQ1_0*" ではなくこちらを使用
)
snapshot_download(
    repo_id = "unsloth/GLM-4.5-Air-GGUF",
    local_dir = "unsloth/GLM-4.5-Air-GGUF",
    allow_patterns = ["*UD-Q4_K_XL*"], # 動的 4bit。動的 1bit の場合は "*UD-TQ1_0*" を使用
)
```

{% code overflow="wrap" %}

```bash
./llama.cpp/llama-cli \
    --model unsloth/GLM-4.7-GGUF/UD-Q2_K_XL/GLM-4.7-UD-Q2_K_XL-00001-of-00003.gguf \
    --threads -1 \\
    --fit on \
    --prio 3 \
    --temp 1.0 \
    --top-p 0.95 \
    --ctx-size 16384 \
    --jinja
```

{% endcode %}

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://unsloth.ai/docs/jp/ji-ben/inference-and-deployment/saving-to-gguf/speculative-decoding.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
