How the model scores your choices

Tally's routes need a probability each and no prose. Three published designs get there in different ways, and a fourth keeps its design secret. Work the numbers for each and see where each one breaks.

What you’ll explore

• A decision model gives every supplied option a score, turns the scores into probabilities with a softmax, and the scores can come from option markers in an encoder, from an LLM's logits for single-token answer codes, or from similarities between separately encoded state and option vectors. How many passes a system needs depends on its implementation, and fixed option budgets limit how many options a design handles well.
