AutoGPT is an experimental open-source project that allows you to create your own custom AI assistant powered by GPT-3 or GPT-4 (when available). The AI assistant can be trained to perform various tasks such as research, analysis, coding, and more based on your prompts and instructions.
AutoGPT is an open-source project and is free to use. However, you may need to pay for access to GPT-3 or GPT-4 models through OpenAI's API or other providers, depending on your usage and requirements.
