Nimble v4 Max

by Bespoke Labs

Nimble v4 Max is Bespoke Labs’ versioned evaluation model for classification, routing, moderation and scoring. It accepts text or JSON state and answers up to 64 keyed yes/no, multiple-choice or rating questions in a System One request. Choice questions and score scales support 2–255 options or levels, with full probability distributions and fractional expected scores. Bespoke documents a 256k-token prompt limit per question and a 1 MiB request-body limit. Nimble returns typed answers rather than generated chat. Opper supports the native System One API and text translation through Decisions; the latter keeps its existing public score limits. Serving precision, inference placement and data-handling guarantees are not established by these model capabilities.
