Clank Uwu Model, developed by cumLabs, offers two AI products for the clank.trade ecosystem: cumAI and cumOS. cumAI brings a range of leading AI models together in one app, where users can chat and generate pictures, as well as access models through an OpenAI-compatible API. The service offers free access to GPT-4.1 nano and two pictures per day, while paid chat models are priced below their listed official rates; other models use xCUM AI credits.

cumOS is an AI companion experience that begins with Yuna. Users can interact with her through a panel after signing in with a wallet. Yuna is designed to have a personality and memory, remember previous conversations, and develop a relationship shaped by interactions. The broader vision is to let users create companions for conversation, play, creativity, and actions within user-chosen boundaries.

The ecosystem uses $CUM and xCUM. xCUM functions as a spendable AI credit, while $CUM holders may qualify for planned xCUM airdrops, and some AI profits are intended to fund $CUM buybacks and burns.
