Messy data in. Deployable AI out. One traceable workflow from label to live endpoint.
Turn raw datasets into training-ready assets with assisted labeling, review loops, structured metadata, and captured dataset lineage before training begins.
Define experiments, compare model versions, track metrics, subgroup checks, and drift context, and manage compute in one place.
Package validated models with environment controls, model cards, audit trails, and deployment records that lead to secure production endpoints.
Purpose-built paths for clinical datasets and annotation as well as inspection, sensor, and operational data for quality and reliability.

AI data infrastructure for building production-grade models
One configurable annotation surface for image, video, text, and audio projects, so multimodal datasets can be labeled without switching tools.
Search, filter, and inspect datasets to find the examples that will most improve a model, then route them into targeted annotation or review queues.
Dashboards for annotation volume, reviewer agreement, and project progress, plus advanced analytics on upper tiers for program-level reporting.
Metered orchestration capacity for running annotation, evaluation, and data-processing workloads, scaled by plan from roughly 1K to 10K compute hours.
