Advanced tooling for model evaluations and data generation

Advanced tooling for model evals and data generation

Multimodal chat evaluations: Live or offline

Compare live, multi-turn conversations with up to 10 models in a built-in chat arena. Capture real-time audio and video evaluations of multimodal models, or do simple offline & single LLM evals.

LLM human preference tool

Analyze and improve step-by-step reasoning, write sophisticated code, compare models side-by-side to identify the most favorable output, or rewrite prompts to train on new preferences.

Prompt and response generation

Generate a dataset of prompts and responses for a variety of fine-tuning & SFT tasks including summarization, classification, question-answering, and generation.

Built-in quality assurance

Real-time statistical analysis

Track data quality in real-time using a robust scientific approach that uses precision and accuracy as two foundational pillars to measure the efficiency and throughput of a project.

Labelbox Monitor

Visualize metrics on projects and team members across a workspace in the built-in Monitor dashboard. Use custom filters to identify outliers and maintain high quality standards.

Benchmarks & consensus

Enhance data quality by comparing labels to a gold standard or by measuring agreement among labelers, ensuring accuracy and consistency in data quality

Flexibility for any task-specific project

Computer vision (CV)

Pre-label data in minutes without code and use leading image labeling tools for bounding boxes, polygons, semantic segmentation, frame-by-frame video annotation, and more.

Natural language processing (NLP)

Use powerful NLP tools for named entity recognition (NER), sentiment analysis, part-of-speech tagging, and text classification. Simplify tasks with model-assisted labeling and advanced search and filter capabilities.

Custom labeling experience

The native HTML editor allows you to customize the way your data rows render in the labeling interface so that you can create custom labeling projects for infinite possibilities.
