About Big-AGI
Big-AGI is a web chat interface for working with many AI models using your own API keys. It connects to providers such as OpenAI, Anthropic, Google Gemini, Mistral and OpenRouter, and to local servers including Ollama, LM Studio and LocalAI.
Its Beam feature sends a question to several models in parallel so you can compare and merge their answers. It also offers personas, text-to-image, voice, code highlighting and PDF import. You can use the hosted app, install it as a web app, or deploy the open-source version yourself.
