Mouse 1
Mouse 1 is a decision model for agent systems that handles small choices and returns probabilities quickly.
Mouse-1 is a decision model designed to handle the hundreds of small choices an agent makes during every task. Users plug it directly into their agent systems to see measurable results right away. It works by taking the agent state and options, then returning a probability. This allows the system to manage routine choices while the main frontier model focuses on reasoning or code. One request answers up to 128 questions in about 100 milliseconds.
