About Singular

A unified interface to 950+ AI models across chat, image, audio, and video. Pick a model or let Singular auto-route compatible chat prompts, then generate image, audio, and video with transparent cost visibility.

Routing

Every prompt is routed to the best model for cost, latency, and capability. Swap providers without touching your thread.

Transparency

Every response shows which model answered, what it cost, how long it took, and which sources were cited.

Control

Bring your own provider keys when you want requests sent with your credential. Routing policy and request details stay visible.

Why we built it

The best model changes by task, by week, and by price. Keeping accounts, keys, and bills with a dozen providers is slow, and comparing models by hand is slower. Singular puts them behind one interface and one balance, so you can switch models without starting over.

Who it is for

People who use AI every day and want the right model without the tab juggling. Developers who want one key and one API for many models. Teams who want to see exactly what they spend.

Who makes it

Singular is built by IMPOSSIBUILD, which provides licensed AI model supply, the products to use it, and the team that gets it into production. Our other product is Innstance, hosting built for AI coding agents.
