OpenAGI is an open-source research and development platform designed to advance artificial general intelligence (AGI). It integrates large language models (LLMs) with domain-specific expert models to tackle complex, multi-step tasks. By employing a combination of benchmark and open-ended tasks, along with a reinforcement learning feedback mechanism, OpenAGI aims to create self-improving AI systems. The platform encourages collaboration and experimentation among developers and researchers to further the progress of AGI.
