面向生产级 AI 的智能体可观测性、评估与持续改进平台
基于 OpenTelemetry 之上的 OpenInference 规范，采集智能体与 LLM 调用的 span、trace 和会话，埋点可跨工具复用。
在 span、trace 与会话三个层级运行评估，对海量生产数据衡量检索质量、工具调用与最终回答的优劣。
内置于产品中的智能体，可检查链路、推断根因，并给出供工程师上线前审阅的修复建议。
当需要让轨迹数据留在自有基础设施内时，可自行部署这一领先的开源追踪与评估工具。
Label Studio is an open-source data labeling and AI evaluation platform from HumanSignal. It handles images, video, audio, text, documents, time series and agent traces in one flexible workspace, and connects to your ML pipeline through an API, Python SDK and webhooks.
Programmable interfaces and custom templates let one workspace handle images, video, audio, text, PDFs, time series and multi-modal tasks.
Build custom benchmarks and rubrics, run side-by-side model comparisons, and grade generated answers against retrieved sources for RAG evaluation.
Collect human preferences, corrections and rankings to feed reinforcement learning from human feedback and fine-tuning workflows.
Connect observability tools, storage and any model to power AI-assisted pre-labeling, benchmarking and continuous evaluation.
