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. ## 價格與方案 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. ## 關鍵功能與能力 - **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. ## 主要使用情境 - **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. ## 限制 - 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 ## 常見問題 ### Is Label Studio free? Yes. Label Studio Community Edition is open source and can be installed free via pip, Homebrew or Docker. A paid Enterprise edition adds advanced modalities, managed deployment and enterprise support. ### What data types can I label? It spans computer vision, NLP and document OCR, audio and speech including transcription and speaker diarization, time-series and sensor data, multi-modal annotations, and LLM, RAG and agent-trace evaluation. ### Who makes Label Studio? HumanSignal maintains the project. The Enterprise edition supports native DICOM reading so annotators keep windowing and slice geometry intact, plus LiDAR point clouds with camera fusion, alongside managed services and support. ### Can it integrate with my ML pipeline? Yes. An API, Python SDK and webhooks let you create projects, stream model predictions and trigger training, active learning or evaluation workflows in real time, and you can pre-label with your own models. ### Label Studio 的每月流量與成長趨勢為何？ Label Studio 目前每月有 13.72萬次造訪，月流量變化為 -2.63萬（成長率 -16.1%）。其主要來源市場為美國（佔比 23.9%），其中包含每月 4.71萬次直接造訪與每月 — 次自然搜尋造訪。 ### Label Studio 是免費的嗎？其定價模式為何？ Label Studio 採用需聯絡報價、免費定價模式。Label Studio Community Edition is free and open source under HumanSignal.
