Big-AGI is an open-source AI suite designed for professionals who expect functionality, aesthetics, simplicity, and speed. Designed as a true multi-model workspace, it goes beyond a simple chatbot to offer a comprehensive working environment around large language models.

Its flagship feature, Beam, allows querying multiple models simultaneously, comparing their responses, and merging them to achieve the best result. The application also includes AI personas, image generation, voice, response streaming, syntax highlighting and code execution, PDF import, and numerous presets for developers.

Big-AGI deploys on-premise or in the cloud and connects to both locally served open-weight models and APIs from major providers. It is an independent project, funded by Pro subscriptions while maintaining a free and open core.
