+ +新立交桥不再定义为“可自部署的兼容网关程序”,而是定义为一个**面向中小企业终端客户的 AI 接入 SaaS**。其核心竞争对象不是底层模型厂商,而是 `newapi`、`sub2api` 这一类“可以快速部署运营但产品完成度不足”的兼容网关产品。对比这些竞品,立交桥 v1 不追求“支持最多功能”,而是明确以三类差异化为主: + +1. 更强的协议兼容与模型接入覆盖。 +2. 更好的用户端体验,降低首次接入和日常使用摩擦。 +3. 更强的管理端运维能力,尤其是可观测、诊断、告警和智能运维能力。 + +v1 的首要价值不是控制台有多复杂,而是用户在**5 分钟内把现有客户端的 Base URL 改掉后直接跑通**。因此,产品增长路径明确选择“开发者主导的自助式增长”,而不是传统企业采购路径。用户先以个人身份注册、充值、创建 Key、完成首次调用成功,再邀请团队成员进入工作区。工作区仍然是计费与治理主体,但首单和首次激活由开发者完成。 + +商业模式选择为**预充值余额 + 按调用量扣费**。这是因为 v1 需要同时支持多上游、多模型、动态成本与按能力矩阵定价。如果一开始就做固定套餐,会把后续模型接入、成本透传和账单解释能力锁死。账户治理模型采用“**工作区是一等主体,个人是登录身份**”的结构:成员、API Key、余额、账单、模型权限、审计和策略都挂在工作区下。 + +## 2. 协议策略、兼容承诺与模型语义 + +立交桥 v1 明确采用**双协议核心产品**策略:`OpenAI` 与 `Anthropic` 都进入 v1 的核心承诺面,不再是“OpenAI 主轴 + Anthropic 辅助适配”。但它也不是简单并排放两套网关,而是“**外部双协议,内部单核心**”:对外保留两套原生协议体验,对内统一收口到一套 canonical 模型目录、能力矩阵、路由策略、额度计量、账务、审计和运维真相层。 + +在 OpenAI 面,v1 的强兼容主链路至少包括: + +- `GET /v1/models` +- `POST /v1/chat/completions` + +在 Anthropic 面,v1 的核心兼容主链路至少包括: + +- `POST /v1/messages` +- 与模型发现、模型映射、错误语义、SDK 行为相关的核心配套能力 + +这两个协议面都进入 v1 核心承诺,且都要覆盖高频高级能力,而不只是最低配文本调用。当前已经确认的能力范围包括: + +- 非流式文本输出 +- 流式输出 +- tool calling / tool use +- 多模态输入 + +但平台**不对所有模型做一刀切承诺**。能力承诺必须按模型能力矩阵显式声明,避免出现“平台说支持,但具体模型一调就报错”的竞品式体验。为此,模型不能再被设计成一个普通字符串,而必须是一个产品契约对象。模型命名采用**双层命名**: + +1. 对外保留兼容名和迁移别名,支持用户“改 Base URL 就能跑”。 +2. 对内维护 canonical model ID、上游映射、价格、能力矩阵、可用区间和路由策略。 + +`model` 字段采用**双模式语义**: + +1. 默认模式下,用户使用兼容名或稳定公共名,优先保证迁移友好。 +2. 高级模式下,用户可以显式指定上游模型、模型别名或受控路由策略。 + +## 3. 核心对象模型与信息架构(待确认) + +为了同时支撑双协议、双层模型命名、工作区计费和后续智能运维,v1 的核心对象建议收敛为以下几类: + +1. `Identity` + 表示登录用户,只负责认证、登录会话和成员关系,不直接承载账务。 +2. `Workspace` + 是一等业务主体,承载余额、充值、账单、成员、API Key、默认路由策略、模型权限和审计边界。 +3. `Credential` + 包括工作区下的 API Key、可能的子 Key、用途标签、状态、权限范围和调用限制。 +4. `Model Catalog` + 平台维护的模型目录对象,不只是模型列表,而是“外部名 - canonical ID - 上游映射 - 能力矩阵 - 价格 - 可用状态”的统一真相层。 +5. `Provider / Upstream` + 表示 OpenAI、Azure OpenAI、Anthropic、DeepSeek、阿里百炼、火山方舟等接入源,以及它们的区域、凭据、速率限制和健康状态。 +6. `Route Policy` + 表示当用户请求某个模型名时,平台如何解析、选择上游、失败时如何回退、何时熔断,以及是否允许智能切换。 +7. `Usage Ledger` + 表示调用级计量事实,记录协议面、模型名、解析后的 canonical model、上游、token/图片/工具调用等费用相关事实。 +8. `Billing Record` + 表示对工作区可解释的账务结果,包括预扣、结算、退款、调整和对账状态。 +9. `Audit Event` + 记录认证、Key 变更、充值、模型策略调整、异常调用、运维处置和权限操作。 +10. `Ops Incident` + 面向管理端与智能运维,记录上游故障、模型异常、路由抖动、错误突增和自动化处置结果。 + +基于这些对象,v1 的控制台信息架构建议按“用户完成任务的顺序”组织,而不是按内部模块组织。控制台一级导航建议优先有: + +- 概览 +- API Keys +- 模型目录 +- 在线调试 +- 用量与账单 +- 路由与策略 +- 运维与诊断 +- 成员与工作区设置 + +这样设计的核心原因是:用户首先要完成首次接入成功,其次才是理解模型能力差异,再之后才是成本、策略和运维。控制台必须服务这一条真实路径,而不是暴露内部模块名。 + +## 4. 当前已确认结论 + +截至本草案版本,以下决定已经确认: + +1. 新立交桥是面向中小企业终端客户的 AI 接入 SaaS。 +2. v1 采用开发者主导的自助式增长路径。 +3. 工作区是一等业务与计费主体。 +4. 商业模式是预充值余额 + 按调用量扣费。 +5. v1 同时把 OpenAI 与 Anthropic 纳入核心承诺面。 +6. OpenAI 面至少强兼容 `GET /v1/models` 与 `POST /v1/chat/completions`。 +7. Anthropic 面提升到接近 OpenAI 同级优先级,纳入 v1 核心能力承诺。 +8. 高级能力范围包括流式、tool calling / tool use、多模态输入。 +9. 平台必须按模型能力矩阵显式承诺,而不是统一口号式承诺。 +10. 模型采用双层命名,对外兼容名,对内 canonical model ID。 +11. `model` 字段采用默认兼容名 + 高级显式指定的双模式语义。 + +## 5. 下一步待确认主题 + +后续设计需要继续确认至少以下几个主题: + +1. OpenAI 面与 Anthropic 面的能力对等边界,到底哪些算 v1 强承诺,哪些算 v1.1。 +2. 模型目录与能力矩阵如何对外展示,是否允许用户自定义别名。 +3. 路由策略是“默认稳态优先”还是“默认智能优选优先”。 +4. 用户端控制台首页与首次接入流的具体结构。 +5. 管理端智能运维的 MVP 边界,到底做告警与诊断,还是直接做自动修复。 + diff --git

+### 成功定义 +上线 30 天后,同时满足: +1. 人工客服介入率 ≤ 40%。 +2. 常见问题一次解决率 ≥ 75%。 +3. 系统可用性 ≥ 99.5%(基于健康检查与告警数据)。 +4. 未发生因客服系统导致的数据泄露或权限越界事件(安全审计通过)。 + +--- + +## 3. 范围 + +### In Scope +1. **多渠道接入层**:通过立交桥现有 `gateway/` 接入 Telegram Bot、Discord Bot、微信公众号/小程序客服消息、网页嵌入式 Widget(至少覆盖这 4 个渠道)。 +2. **对话引擎**:基于大模型的意图识别、上下文多轮对话、知识库检索增强生成(RAG)、工单自动生成。 +3. **知识库管理**:立交桥产品文档(初始化、API Key 管理、模型路由、配额/计费、错误码释义)的结构化索引与更新机制。 +4. **诊断能力**:对接 `platform-token-runtime/` 与 `supply-api/` 的只读查询接口,实现用户身份核验、配额查询、Token 消耗追溯、最近 5 条错误日志检索。 +5. **转人工机制**:当置信度低于阈值、用户明确要求人工、或问题涉及账户封禁/退款/安全审计时,自动创建工单并通知人工客服队列。 +6. **运营后台**:内部运营/客服人员使用的工单看板、会话历史查询、知识库条目增删改查、转人工原因统计。 +7. **埋点与监控**:全链路日志、对话转化率、转人工原因分布、响应延迟 P99、错误率。 + +### Out of Scope +1. **电话/语音客服**:本期仅覆盖文本渠道,不接入语音呼叫中心。 +2. **主动外呼/营销推送**:客服系统仅响应用户主动发起的咨询,不包含主动触达或营销场景。 +3. **多语言支持**:本期优先中文,英文作为 P1 后续迭代,其他语言明确不在本期。 +4. **实时视频/屏幕共享**:诊断过程不提供远程桌面或屏幕共享能力。 +5. **直接修改用户数据**:客服系统仅拥有只读查询权限,任何写操作(如重置密码、修改配额)必须通过工单由人工授权后由独立管理后台执行。 +6. **模型训练/微调基础设施**:不自建模型训练流水线,使用现有大模型 API(如 GPT-4o / Claude / 国内等效模型)通过 Prompt 工程与 RAG 满足需求。 + +### 假设与依赖 +- 假设立交桥 `gateway/` 的 Telegram / Discord / 微信接口已具备 Webhook 接收与消息推送能力,客服系统以独立服务形式接入,不改造 gateway 核心路由逻辑。 +- 假设 `platform-token-runtime/` 与 `supply-api/` 能提供稳定的只读查询 API(用户身份、配额、Token 消耗、近期错误日志),并具备速率限制与鉴权契约。 +- 依赖大模型 API

Gateway 将消息路由至智能客服系统。 +3. 系统执行身份关联: + a. 若渠道已绑定立交桥账户,提取 user_id。 + b. 若未绑定,请求用户提供注册邮箱或 API Key 前缀进行一次性核验(不存储完整 API Key)。 +4. 系统进行意图识别与知识库检索(RAG)。 +5. 若意图命中已知问题且置信度 ≥ 0.85: + a. 返回结构化答案(含操作步骤、文档链接、代码示例)。 + b. 若答案涉及用户个人数据(如配额),调用 supply-api / runtime 只读接口查询后嵌入回复。 +6. 用户确认问题是否解决: + a. 用户反馈“已解决” → 会话关闭,记录解决标记。 + b. 用户反馈“未解决”或继续追问 → 进入多轮对话,最多 3 轮;仍无法解决则触发转人工。 +``` + +### 4.2 异常流程:身份核验失败 + +``` +1. 用户提供邮箱或 API Key 前缀无法匹配系统记录。 +2. 系统回复:“未找到关联账户,请核对注册邮箱或联系人工客服处理账户问题。” +3. 同一会话中身份核验失败累计 3 次 → 自动触发转人工工单,并标记“身份核验失败”。 +4. 系统不记录错误的 API Key 或密码,仅记录失败次数与事件类型。 +``` + +### 4.3 异常流程:大模型 API 故障或超时 + +``` +1. 系统在 5 秒内未收到大模型 API 响应。 +2. 触发 failover:按优先级切换至备用模型供应商(配置至少 2 家)。 +3. 若 failover 后 5 秒内仍无响应: + a. 返回兜底回复:“当前咨询量较大,请稍等或提交工单由人工处理。” + b. 自动生成工单,并附带用户原始问题与会话上下文。 + c. 记录故障事件至监控告警系统。 +``` + +### 4.4 边缘流程:用户明确要求人工 + +``` +1. 用户发送包含“人工客服”、“找人工”、“投诉”等明确关键词的消息。 +2. 系统绕过自动回复逻辑,立即确认:“正在为您转接人工客服,预计排队时间 X 分钟。” +3. 生成工单并推送到客服队列;若队列空闲,立即分配;若排队超过 15 分钟,向用户发送排队进度通知。 +``` + +### 4.5 边缘流程:涉及敏感操作(退款、封禁、安全审计) + +``` +1. 意图识别命中“退款申请”、“账户被封禁”、“怀疑数据泄露”等敏感意图。 +2. 系统自动回复:“该问题需要人工核实,已为您创建优先工单,客服将在 24 小时内通过邮件/站内信回复。” +3. 工单标记为高优先级(P1),并触发内部通知(企业微信/钉钉/Slack)。 +4. 客服系统本身不执行任何账户状态变更或资金操作。
