The collaboration layer for AI engineering teams
Edit, version, diff and roll back prompts from a visual dashboard with no coding, so product, marketing and content teams can iterate on prompts while engineers keep control of the deploy.
Run dataset-backed tests with human and AI graders, trigger regression evals whenever a prompt changes, backtest new versions against historical data and compare prompts across models.
Connect production traces to the exact prompt version that produced them and inspect failures, cost, latency and token usage by feature, model or user.
Build, trace and improve agent workflows with prompts, tool calls, evaluations and logs in one place, so multi-step runs can be tested before they ship.
Build, train, and deploy computer vision for the physical world
Label thousands of images in minutes using frontier models and custom filters, then curate datasets for training.
Combine detection, tracking, and logic blocks to orchestrate actions, update databases, and connect to industrial systems.
Run high-speed inference in the cloud or on edge devices, processing live video and images wherever the application lives.
Get into production quickly with an agent that sees the world, understands what is happening, and triggers actions.
