本地 LLM 的工具调用指南

工具调用是指允许一个 LLM 通过发出结构化请求来触发特定函数（如“搜索我的文件”、“运行计算器”或“调用 API”），而不是在文本中猜测答案。你使用工具调用，是因为它们使输出 更可靠且更新，并且它们让模型 采取真实行动 （查询系统、验证事实、强制执行模式），而不是胡编乱造。

在本教程中，你将学习如何通过工具调用使用本地 LLM，并结合数学、故事、Python 代码和终端函数示例。推理通过 llama.cpp、llama-server 和 OpenAI 端点在本地完成。

当你使用 Unsloth Studio时，工具调用会自动设置。只需选择你的模型，并开启或关闭工具调用。

请看右侧示例，工具调用被自动应用于 Gemma 4。Unsloth 还具有自我修复工具调用功能，确保你始终拥有可工作的工具调用。

我们的指南几乎适用于 任何模型 ，包括：

• Qwen3-Coder-Next, Qwen3-Coder，以及其他 Qwen 比较

• GLM-4.7, 4.6, GLM-4.7-Flash 和 Kimi K2.5, Kimi K2 Thinking

• DeepSeek-V3.1、DeepSeek-V3.2 和 MiniMax

• gpt-oss 和 NVIDIA Nemotron 3 Nano 和 Devstral 2

🔨工具调用设置

我们的第一步是获取最新的 llama.cpp 在 GitHub 这里。你也可以按照下面的构建说明操作。将 -DGGML_CUDA=ON 改为 -DGGML_CUDA=OFF 如果你没有 GPU，或者只想进行 CPU 推理。 对于 Apple Mac / Metal 设备，设置 -DGGML_CUDA=OFF 然后照常继续——Metal 支持默认开启。

apt-get update
apt-get install pciutils build-essential cmake curl libcurl4-openssl-dev -y
git clone https://github.com/ggml-org/llama.cpp
cmake llama.cpp -B llama.cpp/build \
    -DBUILD_SHARED_LIBS=OFF -DGGML_CUDA=ON
cmake --build llama.cpp/build --config Release -j --clean-first --target llama-cli llama-mtmd-cli llama-server llama-gguf-split
cp llama.cpp/build/bin/llama-* llama.cpp

在一个新终端中（如果使用 tmux，请使用 CTRL+B+D），我们创建一些工具，例如两个数字相加、执行 Python 代码、执行 Linux 函数等等：

import json, subprocess, random
from typing import Any
def add_number(a: float | str, b: float | str) -> float:
    return float(a) + float(b)
def multiply_number(a: float | str, b: float | str) -> float:
    return float(a) * float(b)
def subtract_number(a: float | str, b: float | str) -> float:
    return float(a) - float(b)
def write_a_story() -> str:
    return random.choice([
        "很久很久以前，在一个遥远的星系里……",
        "有两个朋友，他们热爱树懒和代码……",

                "required": ["code"],
            },
        },
    },
]

然后我们使用下面的函数（复制并粘贴执行），它会自动解析函数调用，并为任何模型调用 OpenAI 端点：

在这个例子中我们使用的是 Devstral 2，当切换模型时，请确保使用正确的采样参数。你可以在我们的 指南这里查看全部内容.

from openai import OpenAI
def unsloth_inference(
    messages,
    temperature = 0.7,
    top_p = 0.95,
    top_k = 40,
    min_p = 0.01,
    repetition_penalty = 1.0,
):
    messages = messages.copy()
    openai_client = OpenAI(
        base_url = "http://127.0.0.1:8001/v1",
        api_key = "sk-no-key-required",
    )
    model_name = next(iter(openai_client.models.list())).id
    print(f"使用模型 = {model_name}")
    has_tool_calls = True
    original_messages_len = len(messages)
    while has_tool_calls:
        print(f"当前消息 = {messages}")
        response = openai_client.chat.completions.create(
            model = model_name,
            messages = messages,
            temperature = temperature,
            top_p = top_p,
            tools = tools if tools else None,
            tool_choice = "auto" if tools else None,
            extra_body = {"top_k": top_k, "min_p": min_p, "repetition_penalty" :repetition_penalty,}
        )
        tool_calls = response.choices[0].message.tool_calls or []
        content = response.choices[0].message.content or ""
        tool_calls_dict = [tc.to_dict() for tc in tool_calls] if tool_calls else tool_calls
        messages.append({"role": "assistant", "tool_calls": tool_calls_dict, "content": content,})
        for tool_call in tool_calls:
            fx, args, _id = tool_call.function.name, tool_call.function.arguments, tool_call.id
            out = MAP_FN[fx](**json.loads(args))
            messages.append({"role": "tool", "tool_call_id": _id, "name": fx, "content": str(out),})
        else:
            has_tool_calls = False
    return messages

现在我们将在下面展示多种针对不同用例运行工具调用的方法：

编写一个故事：

messages = [{
    "role": "user",
    "content": [{"type": "text", "text": "你能给我写一个故事吗？"}],
}]
unsloth_inference(messages, temperature = 0.15, top_p = 1.0, top_k = -1, min_p = 0.00)

数学运算：

messages = [{
    "role": "user",
    "content": [{"type": "text", "text": "今天的日期加 3 天是多少？"}],
}]
unsloth_inference(messages, temperature = 0.15, top_p = 1.0, top_k = -1, min_p = 0.00)

执行生成的 Python 代码

messages = [{
    "role": "user",
    "content": [{"type": "text", "text": "在 Python 中创建一个 Fibonacci 函数并求 fib(20)。"}],
}]
unsloth_inference(messages, temperature = 0.15, top_p = 1.0, top_k = -1, min_p = 0.00)

执行任意终端函数

messages = [{
    "role": "user",
    "content": [{"type": "text", "text": "把“我是一个快乐的树懒”写入文件，然后再把它打印给我。"}],
}]
messages = unsloth_inference(messages, temperature = 0.15, top_p = 1.0, top_k = -1, min_p = 0.00)

            has_tool_calls = False
    return messages

现在我们将在下面展示多种针对不同用例运行工具调用的方法：

执行生成的 Python 代码

messages = [{
    "role": "user",
    "content": [{"type": "text", "text": "在 Python 中创建一个 Fibonacci 函数并求 fib(20)。"}],
}]
unsloth_inference(messages, temperature = 1.0, top_p = 0.95, top_k = 40, min_p = 0.00)

执行任意终端函数

messages = [{
    "role": "user",
    "content": [{"type": "text", "text": "把“我是一个快乐的树懒”写入文件，然后再把它打印给我。"}],
}]
messages = unsloth_inference(messages, temperature = 1.0, top_p = 1.0, top_k = 40, min_p = 0.00)

我们确认文件已创建，而且确实创建了！

⚡ GLM-4.7-Flash + GLM 4.7 调用

我们首先下载 GLM-4.7 或 GLM-4.7-Flash ，然后通过一些 Python 代码启动它，并在单独的终端中通过 llama-server 运行它（例如使用 tmux）。在这个例子中，我们下载的是大型 GLM-4.7 模型：

# !pip install huggingface_hub hf_transfer
import os
os.environ["HF_HUB_ENABLE_HF_TRANSFER"] = "1"
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*",], # 用于 Q2_K_XL
)

如果你成功运行了它，你应该会看到：

现在在新终端中通过 llama-server 启动它。如果你愿意，可以使用 tmux：

./llama.cpp/llama-server \
    --model unsloth/GLM-4.7-GGUF/UD-Q2_K_XL/GLM-4.7-UD-Q2_K_XL-00001-of-00003.gguf \
    --alias "unsloth/GLM-4.7" \
    --threads -1 \\
    --fit on \
    --prio 3 \
    --min-p 0.01 \
    --ctx-size 16384 \
    --port 8001 \
    --jinja

然后你会得到：

现在在一个新终端中并执行 Python 代码，提醒运行 Tool Calling Guide 我们使用 GLM 4.7 的最佳参数 temperature = 0.7 和 top_p = 1.0

GLM 4.7 的数学运算工具调用

messages = [{
    "role": "user",
    "content": [{"type": "text", "text": "今天的日期加 3 天是多少？"}],

📙 Devstral 2 工具调用

我们首先下载 Devstral 2 通过一些 Python 代码，然后在单独的终端中通过 llama-server 启动它（例如使用 tmux）：

# !pip install huggingface_hub hf_transfer
import os
os.environ["HF_HUB_ENABLE_HF_TRANSFER"] = "1"
from huggingface_hub import snapshot_download
snapshot_download(
    repo_id = "unsloth/Devstral-Small-2-24B-Instruct-2512-GGUF",
    local_dir = "unsloth/Devstral-Small-2-24B-Instruct-2512-GGUF",
    allow_patterns = ["*UD-Q4_K_XL*", "*mmproj-F16*"], # 用于 Q4_K_XL
)

如果你成功运行了它，你应该会看到：

现在在新终端中通过 llama-server 启动它。如果你愿意，可以使用 tmux：

./llama.cpp/llama-server \
    --model unsloth/Devstral-Small-2-24B-Instruct-2512-GGUF/Devstral-Small-2-24B-Instruct-2512-UD-Q4_K_XL.gguf \
    --mmproj unsloth/Devstral-Small-2-24B-Instruct-2512-GGUF/mmproj-F16.gguf \
    --alias "unsloth/Devstral-Small-2-24B-Instruct-2512" \
    --threads -1 \\
    --fit on \
    --prio 3 \
    --min-p 0.01 \
    --ctx-size 16384 \
    --port 8001 \
    --jinja

如果成功，你会看到下面的内容：

然后我们使用以下消息调用模型，并仅使用 Devstral 建议的参数 temperature = 0.15。提醒运行 Tool Calling Guide
