Tether BotPsy: an 800M-parameter AI agent that runs your phone
Tether's BotPsy squeezes an AI phone assistant into 800 million parameters and, the company says, beats rivals 2.5 times its size at everyday tasks.

Tether, the company best known for the USDT stablecoin, has built a small AI agent that is meant to run your phone for you. It is called BotPsy, and it has 800 million parameters.
Parameters are the adjustable numbers inside an AI model, and more of them usually means a bigger, hungrier system. BotPsy is deliberately small. According to the announcement, it is designed to manage everyday tasks locally, and it outperforms rival models about 2.5 times its size at controlling a phone.
What is BotPsy?
BotPsy is an AI assistant, or agent, built to handle routine jobs on a mobile device. The point of keeping it at 800 million parameters is that a model this size can work on the device itself instead of sending everything to a distant server.
The material we have does not say which phones it supports, which benchmarks were used, or when people can try it. Those details are not confirmed here.
Why is Tether building AI?
BotPsy is part of Tether's wider push into decentralized artificial intelligence, meaning AI that does not depend on a few big cloud providers. A company known for stablecoins moving into phone assistants may look like a stretch, but the pitch is simple: smaller models that run locally are cheaper to operate and keep your data closer to home.
The claim that a model 2.5 times smaller can win is the interesting part. If it holds up in independent testing, it suggests that careful design can matter more than raw size for phone control. For now, the result comes from the company itself.
