O que é Label Studio?
Label Studio is an open source data labeling and AI evaluation platform for building annotation workflows across many data types. The product site positions it for human-in-the-loop labeling, AI evaluation, and model training data preparation.
Its documentation and template gallery show support for computer vision, document AI, NLP, audio transcription, time series, conversational AI, RLHF, agent traces, RAG and retrieval evaluation, and other multi-modal workflows. Teams can start from templates, customize interfaces, connect storage and models, and export annotations for downstream use.
O que Label Studio pode fazer?
Templates and configurable interfaces
Use pre-built labeling templates and customizable tags to start faster and adapt interfaces to different data types and evaluation criteria.
Import and export workflows
Import data from local sources and external storage, and export annotations and data when labeling is complete.
ML and automation integration
Connect machine learning models through the documented machine learning integration, custom ML backends, API, Python SDK, and webhooks.
Multi-modal labeling and evaluation
Work across computer vision, NLP, documents, audio, time series, multi-modal data, and agent or LLM evaluation workflows.
Ecosystem integrations
Use the integrations directory to connect Label Studio with storage, model, observability, and infrastructure tools such as S3, GCS, Azure Blob Storage, Docker, Kubernetes, TensorFlow, PyTorch, and LangSmith.
Casos de uso
“Computer vision annotation”
Prepare labeled datasets for image classification, object detection, segmentation, keypoint labeling, and OCR using the computer vision templates and workflow examples.
“NLP, document, and audio labeling”
Label text, documents, chat data, and speech for named entity recognition, sentiment analysis, question answering, audio transcription, speaker diarization, and related workflows.
“LLM and agent evaluation”
Build evaluation workflows for LLMs, RAG systems, and agent traces, including side-by-side comparisons, custom rubrics, and human preference collection.
“ML pipeline integration”
Sync data from external storage, connect models, and export annotations to support training, active learning, benchmarking, and continuous evaluation pipelines.
“Custom task interfaces”
Adapt a template or programmable interface for specialized layouts such as robotics, structured data parsing, rank-and-score tasks, and multi-turn conversation review.
