Big-AGI

Big-AGI Open 🧠

This is the open-source foundation of Big-AGI, the multi-model AI workspace for experts.

Big-AGI is the multi-model AI workspace for experts: Engineers architecting systems. Founders making decisions. Researchers validating hypotheses. You need to think broader, decide faster, and build with confidence, then you need Big-AGI.

It comes packed with world-class features like Beam, and is praised for its best-in-class AI chat UX. As an independent, non-VC-funded project, Pro subscriptions at $10.99/mo fund development for everyone, including the free and open-source tiers.

What makes Big-AGI different:

Intelligence: with Beam & Merge for multi-model de-hallucination, native search, and bleeding-edge AI models like Opus 4.7 1M, GPT 5.5, Gemini 3.1, DeepSeek V4 or Grok 4.3 - Control: with personas, data ownership, requests inspection, unlimited usage with API keys, and no vendor lock-in - and Speed: with a local-first, over-powered, zero-latency, madly optimized web app.

🧠 Intelligence	✨ Experience	⚡ Performance	🔒 Control
Beam & Merge No context junk Purest AI outputs	Flow-state interface Highly customizable Best-in-class UX	Local-first Highly parallel Madly optimized	No vendor lock-in Your API keys AI Inspector

Who uses Big-AGI:

Loved by engineers, founders, researchers, self-hosters, and IT departments for its power, reliability, and transparency.

Choose Big-AGI because you don't need another clone or slop - you need an AI tool that scales with you.

Sure - here is real-world screeengrab as I'm writing this, while running a Beam to extract SVG from an image with Sonnet 4.5, Opus 4.1, GPT 5.1, Gemini 2.5 Pro, Nano Banana, etc.

Get Started

*: Configuration requires your API keys. Big-AGI does not charge for model usage or limit your access.
Why Pro? As an independent project, Pro subscriptions fund all development. Early subscribers shape the roadmap directly.

Self-host and developers (full control)
- Develop locally or self-host with Docker on your own infrastructure – guide
- Or fork & run on Vercel:

Our Philosophy

We're an independent, non-VC-funded project with a simple belief: AI should elevate you, not replace you.

This is why we built Big-AGI to be local-first, madly optimized to 0-latency, launched multi-model first to defeat hallucinations, designed Beam around the humans in the loop, re-wrote frameworks and abstractions so you are not vendor locked-in, and obsessed over a powerful UI that works, just works.

NOTE: this is a powerful tool - if you need a toy UI or clone, this ain't it.

5,000 Commits Milestone

Hit 5k commits last week. That's a lot of code.

Recent work has been intense: - Chain of thought reasoning across multiple LLMs: OpenAI o3 and o1, DeepSeek R1, Gemini 2.0 Flash Thinking, and more - Beam is real - ~35% of our users run it daily to compare models - New AIX framework lets us scale features we couldn't before - UI is faster than ever. Like, terminal-fast

The new architecture is solid and the speed improvements are real.
