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 4.5, Nano Banana Pro, Kimi K2.5 or GPT 5.2 - 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.

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.

<details> <summary>5,000 Commits Milestone</summary>

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.
