Decider 0.8B is the smallest text checkpoint in the Decider family. It reads text and typed questions and returns a probability distribution over 2 to 255 supplied options. With 0.8 billion parameters, a 32,000-token context, and local execution, it targets routing, yes-or-no questions, and short states. Its readout stays focused on those options.

Its practical advantage is the small local footprint within a family that shares the same readout. Decider 2B and the larger variants continue the same decision interface at larger sizes. Define the possible answers before the call, and Decider 0.8B fits directly into routing and rating logic.
