APEX Adaptive Principle Extraction Framework Enables Multi-Dimensional Self-Evolution for Production AI Agents
Researchers propose APEX (Adaptive Principle EXtraction), a three-layer self-evolution framework that simultaneously improves an AI agent's prompt harness, behavioural principles, and workflow topology. Tested on the production-grade Joe AI agent built on NVIDIA Nemotron, APEX achieved a 90% improvement in Health Score over baseline, distilling six novel reusable principles and selecting a research-first workflow scoring 0.900 (+20%). The framework outperforms single-axis harness optimisation and requires only 4 LLM calls (~270 seconds).
