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.
One API key for hundreds of AI models from every major provider
Six hundred plus models for text, image, video, audio, transcription, embeddings, and reranking behind one OpenAI-compatible API.
Requests are rerouted to another provider on outages or rate limits by default, so you don't write custom retry logic.
The auto-router selects a model and provider per request using live marketplace performance and pricing data.
Track spend, tokens, and usage per model, provider, and team member in one place, including bring-your-own-key usage.
