Interfaze

Interfaze is a Y Combinator (P26) startup building a new model architecture for deterministic developer tasks. Interfaze-beta is a multimodal, OpenAI-compatible Chat Completion API (a hybrid Mixture-of-Architecture combining specialized DNN/CNN vision and audio models with a transformer layer) tuned for high accuracy, precision, and consistency on jobs like OCR, speech-to-text, strict structured/JSON output, object detection with bounding boxes, web search, and web scraping through a single endpoint. It exposes a 1M-token context window, 32k max output, verifiable outputs with confidence scores, built-in sandboxed compute and headless browser tools, and works with the OpenAI, Vercel AI, and LangChain SDKs by swapping the base URL. Founded in 2025 by Yoeven D Khemlani and Harsha Vardhan Khurdula (evolved from JigsawStack) and based in San Francisco.

Interfaze publishes 1 API on the APIs.io network: Chat API. Tagged areas include Company, Artificial Intelligence, Machine-Learning, LLM, and OCR.

Interfaze’s developer surface includes documentation, API reference, getting-started guide, pricing, signup flow, support, engineering blog, and 21 more developer resources.
