Comment ça marche

  1. Clarify your goal

    Gather the API keys for the model vendors you actually use — configuration requires your keys, and Big-AGI does not charge for model usage itself.

  2. Get the project

    Clone enricoros/big-AGI from GitHub (or use the install path in the run steps below) and skim its README for the parts relevant to your goal.

  3. Install and configure

    Self-host by developing locally or with Docker following the installation guide, or fork and deploy on Vercel with the documented environment variables.

  4. Run your first task

    Add one vendor key, start a chat with a persona, then run the same prompt through Beam to compare models side by side.

// fonctionnalités

Pourquoi on l'adore

Beam multi-model chats

Beam runs multi-model, multi-modal chats with follow-ups and saveable presets, so you can compare and combine models in one thread.

Many vendors, your keys

Supports state-of-the-art models across OpenAI, Anthropic, Gemini, DeepSeek, xAI, Perplexity and more, configured with your own API keys.

Personas and presets

AI personas and developer presets shape behaviour per task, alongside AGI-style functions.

Text-to-image and voice

Image generation and editing, multi-vendor speech synthesis and transcription, and response streaming built in.

Work-ready inputs

PDF import, code highlighting and execution, and web search with citations for supported models.

Self-host or hosted

Run the MIT open-source version on your own infrastructure, or use the hosted service (with an optional paid Pro sync tier).

Questions fréquentes

Who maintains big-AGI?

enricoros, through the enricoros/big-AGI repository, with the hosted service at big-agi.com.

Is big-AGI free to use?

Yes — the project is open source under the MIT license as recorded for this listing. You can use, modify and distribute it under the MIT terms.

Does big-AGI need a paid API key?

Yes — Big-AGI is a front end: you supply API keys for the model vendors you use and pay them directly; the open-source app itself is free under MIT.

How does big-AGI compare to a single-vendor chat app?

A vendor app locks you to one model family. big-AGI is vendor-neutral — many models, Beam comparison chats, personas and media tools in one self-hostable suite — in exchange for managing your own keys and deployment.

How do I get started with big-AGI?

Clone the repository (or use the documented installer), follow the install and configure steps on this page, and run the smallest real task first — add one vendor key, start a chat with a persona, then run the same prompt through Beam to compare models side by side.
