# K2-Vendor-Verifier ## 概述 K2-Vendor-Verifier 用于检查第三方部署的 Kimi-K2 是否忠实地复现了官方 Moonshot AI API 的工具调用行为。它将官方评估提示集重放至供应商端点，并将其 `finish_reason` 和工具调用载荷与官方基线进行对比。本基准测试改编自 [MoonshotAI/K2-Vendor-Verifier](https://github.com/MoonshotAI/K2-Vendor-Verifier)。 ## 任务描述 - **任务类型**：供应商部署正确性检查（工具调用） - **输入**：包含可用工具定义的多轮对话消息，与上游 K2VV 提示集完全一致 - **输出**：供应商的聊天补全响应（`finish_reason` 和 `tool_calls`） - **对比方式**：将供应商的行为与数据集中提供的官方 Moonshot AI 基线进行比较 ## 核心特性 - 使用官方的 2,000 行 K2-Thinking 样本集（占上游测试集的 50%） - 报告 K2VV 主要指标 `trigger_similarity` —— 工具调用决策相对于官方基线的 F1 分数 - 对触发的工具调用参数根据声明的 JSON Schema 进行格式校验 - 提供原始计数以供合理性检查（`count_finish_reason_tool_calls`、`count_successful_tool_call`） - 托管的数据集保留了官方的 `finish_reason` 和 `tool_calls`，以便未来指标可进行载荷级别的保真度对比 ## 评估说明 - 默认配置使用 **0-shot** 评估；每条样本已包含多轮上下文 - 评估指标：**trigger_similarity**、**schema_accuracy**、**count_finish_reason_tool_calls**、**count_successful_tool_call** - 根据上游 K2VV README，对官方基线的 `trigger_similarity` ≥ 0.73 是大致的接受阈值 - 当前仅发布 `k2_thinking` 子集（K2-0905 将在上游发布后跟进） - 上游基线中少数历史助手消息的 `tool_calls.arguments` 包含格式错误的 JSON；适配器在加载时会对其进行清理 ## 属性 | 属性 | 值 | |----------|-------| | **基准测试名称** | `k2_verifier` | | **数据集ID** | [evalscope/K2VendorVerifier](https://modelscope.cn/datasets/evalscope/K2VendorVerifier/summary) | | **论文** | N/A | | **标签** | `Agent`, `FunctionCalling` | | **指标** | `trigger_similarity`, `schema_accuracy`, `count_finish_reason_tool_calls`, `count_successful_tool_call` | | **默认Shots** | 0-shot | | **评估分割** | `test` | | **聚合方式** | `f1` | ## 数据统计 | 指标 | 值 | |--------|-------| | 总样本数 | 2,000 | | 提示词长度（平均） | 4296.34 字符 | | 提示词长度（最小/最大） | 155 / 36436 字符 | ## 样例示例 **子集**: `k2_thinking` ```json { "input": [ { "id": "74e92786", "content": "You are a help assistant. \n \nWhen faced with logic questions like comparisons or counting, think step by step before answering. \n\nToday is: Friday, September 27, 2025", "role": "system" }, { "id": "7ae46843", "content": "# File 1\nFile type: image/jpeg \nFile name: [PHONE].jpg \nContent: \n04:43 \n4G.l 4..l C92. \nAI ancient-style wallpaper \nHow could I bear it— \nCut \nRoot \nNone \nLife \nBear \nBack Search for matching furniture \nQ \nSearch for matching items \nSave \nTake a joint photo \nAdd to stickers \nShare to WeChat \nCreate group to share", "role": "system" }, { "id": "b5b48843", "content": "If this can be downloaded, then my stuff won't be scarce anymore.", "role": "user" }, { "id": "6c2fcb11", "content": "You’re absolutely right—**if this image can be freely downloaded, saved, and forwarded**, then it’s no longer “scarce” in the **digital sense**; it becomes **infinitely reproducible**.\n\nBut here’s the key point:\n\n> **“Scarcity” isn’t just abo ...
