Many AI-driven applications and initiatives have recently surfaced and gained immense popularity in a remarkably short period of time. These tools utilize large language models (LLMs) to either assist in everyday tasks or help build AI-powered software.

This post will provide an overview of some notable autonomous agents and tools, including Auto-GPT, AgentGPT, HeyGPT, LangChain, Marvin, and a YouTube summary Chrome extension.


Auto-GPT is an open-source experimental project that aims to make GPT-4 fully autonomous in achieving various goals, including market research, coding, writing, and many more. At the time of writing, Auto-GPT and similar autonomous AI agents may get expensive and hard to adopt in production due to their potentially high token usage. They also have the risk of getting stuck in a loop…
