Bring your own key: OpenRouter's API rates, no markup. Keys and chats stay in your browser. Run OpenRouter in parallel with other models, then compare and merge the answers.
OpenRouter is the routing layer: one key, hundreds of models, automatic fallback. It is not where you organize the work. Point Big-AGI at that key and the catalog turns into an expert workspace.
| Capability | Through your OpenRouter key | Inside Big-AGI |
|---|---|---|
| Model catalog | Hundreds, one key | The same catalog, same key |
| Reasoning and parameter control | Router-flattened | Vendor-accurate ranges |
| Merging multiple answers | Basic Fusion | Advanced and custom merges |
| Personas and saved prompts | Not the router's job | Built in, with memory |
| Chat history and attachments | Bring your own | Local-first, yours |
| Request transparency | API-level | AI Inspector on every call |
You do not need credits to begin. OpenRouter serves 20+ free models, including Llama, Qwen, and GPT-OSS, and Big-AGI runs them the moment your key is linked. Add a Google key for the Gemini free tier and you have a second vendor at no cost. Free usage runs under OpenRouter's own daily and per-minute limits, so it is built for trying things, not production loads. When you outgrow it, the same key unlocks every paid model at OpenRouter's rates.

1
Create an API key at the OpenRouter console.
2
Paste it into Big-AGI's model settings.
3
Start chatting, or Beam it against other models and fuse the answers.
Add one OpenRouter API key and reach hundreds of models from dozens of providers through a single bridge. Big-AGI adds no markup and no intermediary: the billing relationship runs directly between you and OpenRouter. You bring the aggregator, Big-AGI brings the workspace.
Turn on Direct Connection and the browser talks to OpenRouter directly, skipping the Big-AGI server, when your key is client-side and OpenRouter allows it. Your keys stay in your browser, not on Big-AGI's servers. Chats are stored locally first, and sync only if you turn it on. Nothing is added to your system prompt, and the AI Inspector shows the exact request, the token counts, and a cost estimate for every call.
This is the part a router cannot do for you. Send one prompt to models from different providers at once, Anthropic next to OpenAI next to an open model OpenRouter hosts. Where they agree, you can trust the answer. Where they differ, you have caught something worth a second look. Fusions then combine, cross-check, and synthesize the parallel answers instead of just picking the best one. Big-AGI has shipped and refined this workflow since 2024. Parallel runs use more tokens than a single chat.
Big-AGI is an independent, open-source client. It is not affiliated with or endorsed by OpenRouter.
Your key, your data, your choice of model. Big-AGI is open source and self-hostable, so you can check exactly how OpenRouter is called.
