The multimodal data layer for computer vision and physical AI teams
Native video, image, LiDAR, audio, text, and sensor-fusion labeling in one workflow, with label lineage and quality controls built for production scale.
Use embedding-based search and model-in-the-loop curation to surface rare edge cases and close distribution gaps before they hurt model performance.
Orchestrate RLHF, rubric-based evaluation, and pairwise comparison for models in production, then route failures back into training.
Access vetted domain experts for annotation and training-ready data collection, fully integrated with the Encord platform.
Label any data. Evaluate any AI.
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.
