Interfaze runs its model-serving backend on Vercel, handling 50 million API requests a month for engineering teams in legal, healthcare and finance. The company builds models for deterministic work that general-purpose LLMs handle poorly, including document processing, OCR, object detection, web scraping, speech to text and classification. Founder Yoeven Khemlani says an LLM asked for an invoice total returns a number with no easy way to check its origin, so Interfaze's models return the number with a bounding box and a confidence score. The backend runs as serverless functions in the same codebase as the frontend, with Vercel Sandbox executing code the model writes and Fluid compute scaling with traffic. AI Gateway fails requests over to another provider when one throttles or goes down, and lets Interfaze compare providers serving the same open source model at different quality. The Workflow SDK runs lifecycle email sequences with durable execution, and preview deployments carry new model versions to customers before release. Interfaze recently released Interfaze 1 Lite, an open-weight version of its model that runs on a single GPU and is served through the same API.
