AI仙宝项目介绍
Agent 配套工具 · 2026-11-09 更新 · 本站尚未实测
Langfuse 是一个开源的 AI 工程平台，面向智能体评测（agent evals）与可观测性（observability）。README 将其定位为"open source AI engineering platform for agent evals and observability"，用于统一记录公司内的每次 AI 调用与团队构建的每个智能体：跟踪用量与成本、追踪与评测智能体，并利用生产数据改进 AI 应用。
它提供两种使用形态：Langfuse Cloud（官方托管部署）与自托管（Self-Host）。README 说明自托管可在数分钟内完成，Docker Compose 方式约 5 分钟即可在单机或单台虚拟机上运行。README 同时标注团队自 2026 年 1 月起归属 ClickHouse，并持续远程与多地办公招聘。
需要说明的是，本项目是平台与工具链，其核心价值在于为已有 LLM 应用与智能体提供可观测与评测能力，并非一个开箱即用的业务智能体本身。
核心能力
点击能力名称查看输入、输出和原文依据。
- AI 可观测性：通过埋点接入应用并上报 traces，追踪 LLM 调用及检索、嵌入、智能体动作等逻辑；可检查与调试复杂日志和用户会话，基于 OpenTelemetry 构建。
- 提示词管理（Prompt Management）：集中管理、版本控制并协作迭代提示词；README 称借助服务端与客户端强缓存，迭代提示词不会给应用增加延迟；LLM Playground 可测试提示词与模型配置。
- Skill 管理（beta）：为智能体技能提供版本与标签，技能由包含任务说明的
SKILL.md及可选附属文件组成；可在不改应用代码的情况下升级或回滚版本，并将技能版本与产生的 traces 关联。 - 评测：支持 LLM-as-a-judge、代码评测器、用户反馈收集、人工标注，以及通过 API/SDK 的自定义评测流水线；可用 Datasets and Experiments 构建测试集与基准。
- AI Gateway（beta）：为组织提供调用模型供应商的统一端点，集中保存供应商凭据，按用户或服务账号分配网关密钥、集中审批模型、按用户/密钥/模型统计 AI 支出，并把每次调用记录为 Langfuse trace。
- 指标与仪表盘：通过自定义仪表盘、指标 API 与告警，按任意维度跟踪延迟、成本与质量。
- API 与 SDK：提供 OpenAPI 规范、Python 与 JS/TS 类型化 SDK、Langfuse CLI，以及面向编码智能体的 Langfuse Agent Skill。
实际应用场景
适用场景
- 需要对 LLM 应用或智能体做端到端追踪与调试，定位检索、工具调用、智能体动作等环节的问题。
- 希望把提示词集中版本化，并能在 playground 中快速试改。
- 需要在发布前用数据集与实验做回归测试，或上线后持续用生产数据评测质量。
- 需要按用户、密钥或模型统计 AI 成本，并通过统一网关管理多家模型供应商凭据。
- 组织有数据合规或部署要求，希望在自己的基础设施上自托管。

## ✨ Core Features
<img width="2400" alt="features" src="https://github.com/user-attachments/assets/0fad3dee-f3ad-423c-9f0d-7ccd0f26cc2d" />
- [AI Observability](https://langfuse.com/docs/observability/overview): Instrument your app and start ingesting traces to Langfuse, thereby tracking LLM calls and other relevant logic in your app such as retrieval, embedding, or agent actions. Inspect and debug complex logs and user sessions. Built on OpenTelemetry. Try the interactive [demo](https://langfuse.com/docs/demo) to see this in action.
- [Prompt Management](https://langfuse.com/docs/prompt-management/overview) helps you centrally manage, version control, and collaboratively iterate on your prompts. Thanks to strong caching on server and client side, you can iterate on prompts without adding latency to your application. The [LLM Playground](https://langfuse.com/docs/prompt-management/features/playground) lets you test prompts and model configurations; when you see a bad result in tracing, you can jump straight to the playground to iterate on it.
- [Skill Management](https://langfuse.com/docs/skill-management/overview) (beta) brings versioning and labels to agent skills: a `SKILL.md` with task instructions plus optional supporting files. Promote or roll back versions without changing application code, and link skill versions to the traces they produced.
- [Evaluations](https://langfuse.com/docs/evaluation/overview) are key to the AI agent development workflow, and Langfuse adapts to your needs. It supports LLM-as-a-judge, code evaluators, user feedback collection, manual labeling, and custom evaluation pipelines via APIs/SDKs. Use [Datasets and Experiments](https://langfuse.com/docs/evaluation/experiments/datasets) to build test sets and benchmarks for pre-deployment testing and continuous improvement.
- [AI Gateway](https://langfuse.com/docs/gateway/overview) (beta) gives your organization one endpoint for calls to your model providers. Keep provider credentials in one place, hand out per-user or service account gateway keys, approve models centrally, track AI spend per user, key, and model, and record every call as a Langfuse trace.
- [Metrics and Dashboards](https://langfuse.com/docs/metrics/overview): Track latency, cost, and quality across any dimension with [custom dashboards](https://langfuse.com/docs/metrics/features/custom-dashboards), the metrics API, and alerts.
- [Comprehensive API](https://langfuse.com/docs/api-and-data-platform/overview): Langfuse is frequently used to power bespoke AI engineering workflows while using the building blocks provided by Langfuse via the API. An OpenAPI spec, typed SDKs for Python and JS/TS, the [Langfuse CLI](https://langfuse.com/docs/api-and-data-platform/features/cli), and the [Langfuse Agent Skill](https://langfuse.com/docs/api-and-data-platform/features/agent-skill) for coding agents are available.

## 🚀 Quickstart
Instrument your app and start ingesting traces to Langfuse, thereby tracking LLM calls and other relevant logic in your app such as retrieval, embedding, or agent actions. Inspect and debug complex logs and user sessions.
### 🤖 Agentic installation (recommended)
Install the [Langfuse Agent Skill](https://github.com/langfuse/skills) to let your coding agent access all Langfuse features, then ask it to add tracing to your application:
```txt
Install the Langfuse Agent Skill from github.com/langfuse/skills
and use it to add tracing to this application with Langfuse
following best practices.
```
You can also install the skill with the [skills CLI](https://www.npmjs.com/package/skills) (`npx skills add langfuse/skills --skill "langfuse"`) or the [Langfuse Cursor plugin](https://cursor.com/marketplace/langfuse). If your agent supports MCP, add the [Langfuse Docs MCP server](https://langfuse.com/docs/docs-mcp) (`https://langfuse.com/api/mcp`, no authentication) so it can look up current documentation while it works. See the [get started guide](https://langfuse.com/docs/observability/get-started) for details.
### 🛠️ Manual installation
#### 1️⃣ Create new project
1. [Create Langfuse account](https://langfuse.com/cloud) or [self-host](https://langfuse.com/self-hosting)
2. Create a new project
3. Create new API credentials in the project settings
#### 2️⃣ Log your first LLM call
The [`@observe()` decorator](https://langfuse.com/docs/observability/sdk/instrumentation#observe-wrapper) makes it easy to trace any Python LLM application. In this quickstart we also use the Langfuse [OpenAI integration](https://langfuse.com/integrations/model-providers/openai-py) to automatically capture all model parameters.
> [!TIP]

## 🔒 Security & Privacy
We take data security and privacy seriously. Please refer to our [Security and Privacy](https://langfuse.com/security) page for more information.
### Telemetry
By default, Langfuse automatically reports basic usage statistics of self-hosted instances to a centralized server (PostHog).
This helps us to:
1. Understand how Langfuse is used and improve the most relevant features.
2. Track overall usage for internal and external (e.g. fundraising) reporting.
The telemetry does not include raw traces, prompts, observations, scores, or dataset contents. We document the exact fields that are collected, where they are sent, and the implementation reference in our [telemetry docs](https://langfuse.com/self-hosting/security/telemetry).
For Langfuse OSS, you can opt out by setting `TELEMETRY_ENABLED=false`.
