DeepSeek Model Output

ollama返回

Ollama 的命令行输出是直接、未经格式化的文本，忠实反映了模型的原始输出。任何格式化（如 标签）都是由模型本身生成的，不是 Ollama 添加的。交互模式允许你持续提问，而单次查询则适用于一次性的问题解答。

DeepSeek-R1 模型的设计特性就是会在其输出中包含 <think> 标签来展示其推理过程。以下是关于这个特性的具体说明：

• 推理过程的展示：DeepSeek-R1 模型特别注重逻辑和推理，因此它会输出一个 <think> 块来展示如何从问题到答案的思考过程。这种做法有助于理解模型的决策路径，特别是在处理复杂问题时。

• 无额外格式化：这种 <think> 标签是模型本身输出的一部分，而不是任何外部工具或 API 添加的。Ollama 或其他类似的运行环境只是忠实地将模型的输出显示出来，因此你会看到这些标签直接出现在文本中。

• 可能使用 Markdown：
  • 虽然 DeepSeek-R1 主要以 <think> 标签来展示推理过程，但它也可以输出使用 Markdown 语法的文本。这取决于模型训练时的数据集和任务。如果问题或提示要求以某种格式回答，模型可能尝试使用 Markdown 来增强答案的可读性。
  • 例如，如果你问模型如何编写一个列表，它可能会输出：

    <think>这个问题需要我展示如何使用Markdown语法来创建一个列表...</think>
        
    - 第一项
    - 第二项
    - 第三项
    

• 依赖于提示（Prompt）：
  • 模型输出的格式和详细程度可以受提示的影响。如果你明确要求模型以某种方式组织回答，它可能会遵循这些指示，包括使用 Markdown 或其他文本格式化手段。
• Ollama 的角色：
  • Ollama 作为一个模型运行工具，负责执行模型并展示其输出。它不会对输出的文本进行额外的结构化处理或改变，所以你看到的任何格式（包括 <think> 标签）都是模型直接生成的。

因此，当你使用 Ollama 运行 DeepSeek-R1 时，你会直接看到模型生成的带有推理过程和可能的 Markdown 格式的输出。这意味着如果你在命令行或任何其他环境中使用这个模型，你会得到包含这些特征的纯文本输出。
