GSEP - "Genomic Self-Evolving Prompt" – AI prompts that evolve like DNA

Summary: GSEP is an open-source TypeScript framework that enables AI agents to self-evolve their prompts using a biological DNA model. It organizes prompts into four chromosome layers that mutate and adapt automatically without fine-tuning the underlying language model.

What it does

GSEP structures AI prompts into four layers—immutable identity, skills/tools, user preferences, and content firewall—that mutate and compete to optimize prompt quality. It supports multiple LLMs including Claude, GPT-4, Gemini, and Ollama, applying automatic mutation and rollback based on fitness across six dimensions.

Who it's for

Developers and AI practitioners seeking scalable prompt engineering that adapts per user without retraining models.

Why it matters

It solves prompt degradation over time by evolving instructions automatically, eliminating manual rewriting and model fine-tuning.
