## 概览

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.

## 定价与套餐

Label Studio Community Edition is free and open source under HumanSignal. Label Studio Enterprise is quote-based and sold via HumanSignal, adding advanced modalities, managed deployment options and enterprise support.

## 关键功能与能力

- **All data modalities:** Programmable interfaces and custom templates let one workspace handle images, video, audio, text, PDFs, time series and multi-modal tasks.
- **LLM, RAG and agent evaluation:** Build custom benchmarks and rubrics, run side-by-side model comparisons, and grade generated answers against retrieved sources for RAG evaluation.
- **RLHF and fine-tuning data:** Collect human preferences, corrections and rankings to feed reinforcement learning from human feedback and fine-tuning workflows.
- **ML pipeline integration:** Connect observability tools, storage and any model to power AI-assisted pre-labeling, benchmarking and continuous evaluation.
- **Specialist enterprise modalities:** Label Studio Enterprise adds native DICOM handling that preserves windowing and slice geometry, plus LiDAR point clouds with calibrated camera fusion.

## 主要用例

- **Image and video annotation (Computer vision teams):** Label images and video with classification, detection boxes, polygons and keypoints, and track objects frame by frame.
- **LLM and RAG evaluation (LLM and RAG engineers):** Build custom benchmarks and rubrics, compare model outputs side by side, and grade RAG answers against their source documents.
- **Speech and time-series labeling (Audio and sensor teams):** Transcribe audio, perform speaker diarization and tag emotion, or annotate sensor and time-series data for classification and segmentation.
- **Agent trace review (AI platform teams):** Turn observability traces into human-reviewed training data and run human-in-the-loop quality passes on production traffic.

## 局限

- The most advanced modalities (native DICOM, LiDAR, many enterprise connectors) are gated behind the paid Enterprise tier
- Self-hosting the open-source edition means you own setup, upgrades and scaling
- Very flexible configuration can be intimidating for teams that want a fully managed turnkey product

## 常见问题
