AgentRunner.ai is a platform that enables the creation and training of fully autonomous AI agents. Leveraging the power of GPT-4, users can set goals and allow agents to determine how to achieve them. The platform is user-friendly and does not require technical expertise or programming skills. It supports observing agent behavior, running agents to execute tasks or learn new skills, defining the actions agents can perform, integrating with OpenAI or Google Cloud accounts, viewing detailed logs of agent actions, and accessing the accumulated memory of agents.
