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.
Intelligence: with Beam & Merge for multi-model de-hallucination, native search, and bleeding-edge AI models like Opus 4.5, Nano Banana, Kimi K2 or GPT 5.1 - 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.

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.
| Tier | Best For | What You Get | Setup |
|---|---|---|---|
| Big-AGI Open (self-host) | IT | First to get new models support. Maximum control and privacy. | 5-30 min |
| big-agi.com Free | Everyone | Full core experience, improved Beam, new Personas, best UX. | 2 min* |
| big-agi.com Pro $10.99/mo | Professionals | Everything + Sync across unlimited devices + 1GB storage | 2 min* |
*: 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:
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.
- Open 2.0.2: Speex multi-vendor speech synthesis, Opus 4.5, Gemini 3 Pro, Nano Banana Pro, Grok 4.1, GPT-5.1, Kimi K2 + 280 fixes
- Big-AGI Open is ready and more productive and faster than ever, with:
- Beam 2: multi-modal, program-based, follow-ups, save presets
- Top-notch AI models support including agentic models and reasoning models
- Image Generation and editing with Nano Banana and gpt-image-1
- Web Search with citations for supported models
- UI & Mobile UI overhaul with peeking and side panels
- And all of the Big-AGI 2 changes and more
- Built for the future, madly optimized

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.
