Decider 1
meraGPT's hosted decision model (state-decider-1). Answers yes/no, choice and rubric-score questions over one state as calibrated distributions in a single pass, on the System One schema, so the typesafe-sdk works by changing its base URL.
Not related to Mapika's open decider models. Text only; a request holds at most 4,096 tokens and a Choice question at most ten options. On a 400-case, 2,000-decision typed-decisions benchmark whose reference answers come from a teacher-model ensemble, meraGPT reports 0.768 accuracy (Jev 1.13: 0.727), KL 0.096 from the references (Jev: 1.442) and Brier 0.052 (Jev: 0.148), from a single run. $0.03 per million input tokens, output free, with $1 of free credit. Weights are proprietary.

- choice — picks one option from a set
- score — places the input on an ordered scale
- noul — answers a yes/no question with one calibrated probability
- classify — assigns a category from a fixed taxonomy
- route — sends the input to one of several destinations
