Jev is TypeSafe's decision model, built for fast, low-cost tasks such as categorizing customer messages. This illustrated example shows user-defined categories, probabilities and application-code routing, followed by an optional GPT or Claude writing step.
Jev reads natural-language text and returns structured decisions; it does not generate free-form written replies. GPT and Claude can also return structured outputs. Choose and test a model for your actual workload, including accuracy, latency, cost and escalation thresholds. TypeSafe's advertised performance comparisons are vendor measurements whose workload, probability-output and wrapper methodology affect results; this video makes no universal comparative claim or measured savings promise. Confidence thresholds require validation on representative examples.
