Cisco Foundation AI open-sourced FAPO (Fully Automated Prompt Optimization), a system driven by Claude Code that autonomously optimizes multi-step LLM pipelines. FAPO evaluates the entire chain, attributes failures at the step level, proposes variants across prompts, parameters, and chain structure, then validates each variant via an independent reviewer. In Cisco’s evaluation, FAPO won 15 of 18 model benchmark comparisons, outperforming GEPA.
