Digital Event Horizon
The world of artificial intelligence has witnessed a significant leap forward with the introduction of BotPsy, a cutting-edge, on-device personal assistant developed by Tether Data, S.A. de C.V. d.b.a. Tether AI Research. This groundbreaking model boasts an impressive 0.8 billion parameters, solidifying its position as a leader in the realm of agentic language models. BotPsy has demonstrated exceptional performance in various benchmarking tests, surpassing several other models in its class, including Qwen3.5-2B-Think, a model 2.5 times its size. The model excels in instruction following, multi-turn conversations, and tool use, while showing promise in knowledge retention and inference efficiency. With its ability to perform complex tasks with fewer reasoning tokens and fewer assistant turns, BotPsy is poised to revolutionize the way we interact with technology and shape the future of AI research and development.

The world of artificial intelligence has witnessed a significant leap forward with the introduction of BotPsy, a cutting-edge, on-device personal assistant developed by Tether Data, S.A. de C.V. d.b.a. Tether AI Research. This groundbreaking model boasts an impressive 0.8 billion parameters, solidifying its position as a leader in the realm of agentic language models. BotPsy is designed to serve as a personal assistant, capable of performing a variety of simple tasks, including web search & research, travel & lifestyle, commerce & finance, business & customer operations, device & vehicle control, files & documents, calendar, and email & messaging.
The development of BotPsy was made possible by a combination of four stages of training, each utilizing a distinct learning signal: demonstrations, specialist teachers, and verifiable rewards. The first stage, supervised fine-tuning, focused on tool-use conversations, including multi-turn agent trajectories from simulated environments, replayed single, parallel, and multi-step calls, and cases where no tool should be called. The second stage, on-policy distillation, allowed the model to generate its own responses while receiving feedback on every token from specialist teachers. The third stage, reinforcement learning, further enhanced the model's performance on tool use and general reasoning.
BotPsy has demonstrated exceptional performance in various benchmarking tests, surpassing several other models in its class, including Qwen3.5-2B-Think, a model 2.5 times its size. The model excels in instruction following, multi-turn conversations, and tool use, while showing promise in knowledge retention and inference efficiency. Its ability to perform complex tasks with fewer reasoning tokens and fewer assistant turns has garnered significant attention in the AI community.
However, BotPsy also has its limitations, particularly in open-ended search and a few areas where Qwen3.5-2B-Think still leads. The model is best suited for tasks of low to medium difficulty and is not intended for safety-critical or high-stakes automated decisions or applications involving sensitive topics.
The introduction of BotPsy marks a significant milestone in the evolution of personal AI, offering a more efficient, private, and secure alternative to existing models. As Tether Data continues to advance the capabilities of BotPsy, it is poised to revolutionize the way we interact with technology and shape the future of AI research and development.
