big-AGI
A multi-model AI workspace for experts with Beam de-hallucination.
Run 500+ models across 20+ vendors with Beam validation and local-first UI.
Big-AGI is a high-performance open-source AI workspace tailored for engineers, researchers, and technical founders. It lets you query over 500 models simultaneously, de-hallucinate responses using Beam, and inspect requests directly without vendor lock-in.
What it is
The platform provides a local-first web interface to run multi-modal AI tasks, text-to-image generation, voice synthesis, and code execution. Its signature Beam feature queries multiple frontier models like GPT, Claude, and Gemini concurrently and merges the output for higher accuracy.
Who it's for
It suits technical professionals, developers, and power users who manage multiple AI vendor API keys and need rigorous output validation. It is not intended for casual users looking for a basic chatbot clone or a toy UI.
