SmartGPT is an experimental autonomous agent system designed to give LLMs such as GPT-3.5 and GPT-4 the ability to complete complex tasks without human input. It achieves this by breaking down larger problems into smaller sub-problems and collecting information through internet access and other external sources. The framework features first-class plugin support, a configurable YAML-based system, and a smart action-execution engine with static tool-chaining for consistent results.
