Decision models emerge as a category, with three major vendors launching this week

Decision models — a new model category that outputs a judgment instead of text — drew product launches from OpenAI, Databricks and Perplexity within the same week.

Jev, from TypeSafe, launched in mid-September; per Jamin Ball's Clouded Judgement column, it was used by about 13% of paid teams on Vercel's AI Gateway within 24 hours, and one article it cites reports input pricing of $0.042 per million tokens.

The category targets classification and routing tasks at prices far below general models, but accuracy and latency still lack independent comparison, and how much general-model usage it can replace remains unknown.
