Choice
Ask a question with named options and receive a probability distribution over those options.
BACKWOODS MODELS / COMING NEXT / MODEL
A judgment your code can act on.
Biff is an upcoming open-weight System One model. Supply context and typed questions; get probabilities over the answers you define.
THE PROJECT, IN PRACTICE
What you can do with it.
Score
Define an ordered scale and get a distribution over its levels, together with an expected score.
Condition
Ask whether a stated condition holds and receive its probability.
One state, many questions
The design reads a shared state and answers multiple typed questions against that context without generating a text answer.

- 03
Use the probabilities
Threshold, route, or rank using the structured output in your application.

TAKE IT FOR A SPIN
Start here.
Biff is still in development. Weights are planned for Hugging Face under Apache 2.0. There is no released download or public inference endpoint to try yet.
STATUS & REQUIREMENTS
Upcoming model. Release timing and measured production performance have not been announced here. Planned licensing describes intent, not an already available release.
