Crun is a unified AI API platform that aggregates 100+ top image, video and audio models (from providers like Google, OpenAI, ByteDance and others) behind a single, OpenAI‑compatible interface. Developers can pick models for text‑to‑image, image‑to‑image, text‑to‑video, image‑to‑video, and audio generation; test in an interactive playground; and integrate via REST, Python, JS or cURL. Crun focuses on cost optimization, stable performance, model cataloging, monitoring, and secure token-based access to scale multimodal applications quickly.
