Dataiku puts Jev decision model inside LLM agents: typed judgments at cents per 1,000 calls

Dataiku integrated TypeSafe's Jev—a new class of "decision model" alongside OpenAI's Decisions API that returns typed judgments with probabilities (yes/no, choice, score)—into its visual agent canvas and benchmarked it against LLM agents on 200 supplier requests at a few cents per thousand calls. The design principle: explicitly structure agent graphs with decide/analyze sub-nodes (system 1 vs system 2), likely the state of agentic design for six months until variable token pricing arrives.
