Automatically capture every call to Jev, TypeSafe AI’s System One decision model. Each systemOne call becomes a decision span with the model version, token usage, cost, and the questions, answers and probabilities.

Setup

Requires @traceroot-ai/traceroot 0.5.0 or newer and Node.js 20 or newer.

Usage

Once initialized, all systemOne calls are captured automatically:
