https://github.com/Significant-Gravitas/Auto-GPT "Auto-GPT is [...] driven by GPT-4, chains together LLM "thoughts", to autonomously achieve whatever goal you set.

From the docs:
"💀 Continuous Mode ⚠️
Run the AI **without** user authorization, 100% automated. Continuous mode is NOT recommended."

AutoGPT will attempt to write and improve it's own code, debug it, and repeat, you as user can guide it or go fully auto 😱
