AgentGPT
AgentGPT is an open‑source, browser‑run tool from Reworkd that lets you name an agent, set a goal, and have it autonomously plan, research, and execute tasks in iterative loops. It’s designed for fast experimentation and demos, with ready‑made templates for research, branding, and trip planning—no engineering setup required.
BabyAGI
BabyAGI is pioneering the future of autonomous AI through an experimental framework designed for self-building agents. Born from the insight that the most effective path to general autonomous agents is radical simplicity, BabyAGI focuses on creating the minimal viable system capable of building and evolving itself. At its core is functionz, an innovative function framework that revolutionizes how autonomous agents manage their capabilities. This database-driven system stores, manages, and executes functions through an intelligent graph-based architecture that tracks imports, dependencies, and authentication—all with automatic loading and comprehensive logging. BabyAGI provides developers with an intuitive dashboard for seamless function management, real-time updates, and detailed log analysis, making autonomous agent development accessible and transparent. By embracing a self-building philosophy, BabyAGI represents a fundamentally new approach to creating AI systems that can adapt, grow, and improve autonomously.
