About Big-AGI

Big-AGI is a multi-model AI workspace aimed at engineers, founders and researchers who want to use several AI models from one interface. This repository is the open-source foundation of the product, and it can be deployed on your own infrastructure or in the cloud.

Its main feature is Beam, which sends a question to multiple models and merges the answers, with the aim of reducing hallucinations. Further capabilities include AI personas, native search, image generation from text, voice, streamed responses, code highlighting and execution, PDF import and developer presets. Repository topics show connections to APIs from OpenAI, Anthropic, Gemini, DeepSeek, Perplexity and xAI.

Big-AGI is written in TypeScript and licensed under MIT. The project describes itself as independent and not venture-funded, with a Pro subscription at $10.99 per month that pays for development, which also benefits the free and open-source tiers.
