What it does

Switches between OpenAI, Anthropic, Google and other providers in a single interface, and will send the same prompt to several at once so you can compare answers — alongside image generation, PDF reading and the usual chat workspace features. Self-host via Docker or Vercel, or use the hosted build; keys and their costs are yours. Beam-style multi-model queries bill per provider, which is worth internalising before you make it a habit.

big-AGI FAQ

Is big-AGI free?: big-AGI itself is free, but it needs an API key for an external AI service. That service charges separately, though some have a free tier.
Do I need to install anything or write code to use big-AGI?: It needs the command line. If you are not comfortable typing commands, expect to get stuck during setup.
Does big-AGI work on a phone?: No. It needs a computer.
Can I use big-AGI commercially?: The licence is MIT, which permits commercial use. Conditions such as keeping the copyright notice still apply, so read the licence text before shipping it inside something.
