FAQ

Getting started

Do I need to configure anything to use the knowledge base? No. New accounts have a default chat model open, and the knowledge-base embedding / rerank / contextual models run on platform defaults. Create a project, upload a document, and ask — it works with zero setup.

Why can't I choose my own embedding model? All projects share one vector store, so the embedding model (and its vector dimensions) has to be identical across every user — otherwise existing vectors would be incompatible. That's why embedding / rerank / contextual are platform-wide defaults rather than per-user settings. Your channels are for the chat model. See Model channels.

Do I need my own API key? Only if you want to use a specific provider or your own key for the chat model. Add it under Model channels. Retrieval needs no key from you.

Documents & privacy

Which file types can I upload? PDF, Word, Excel, PowerPoint, HTML, CSV, JSON, Markdown, and plain text. See Knowledge base.

Are my documents private? Yes — documents live in your own projects. API keys you issue are fenced to the projects you choose, and integrations only see what you scope them to.

I changed a setting — do old documents update automatically? No. Indexing happens at upload time, so existing documents keep their current index. Re-upload a document to apply new settings to it. Your existing vectors and answers are otherwise unaffected.

Agent mode

What does Agent mode add over normal chat? Multi-step tool use, code execution, and real generated files (DOCX, PPTX, XLSX, PDF) grounded in your knowledge base. Toggle the 🤖 智能体 (Agent) chip just above the chat input. See Agent mode.

Why is my agent request queued? Agent turns run one at a time per conversation. Send the next request after the current one finishes.

yongzhi-im (IM)

Is it safe to connect my IM? Yes. The bridge never receives your real API key — it gets a derived, fenced, revocable key created when you scan the QR. Binding codes last 10 minutes and work once. See yongzhi-im.

How do I disconnect an IM? Click × next to the connection in Settings → API Keys. Only that connection's derived key is revoked; everything else keeps working.

My IM bot says it has no access to a project. The key you bound is fenced to specific projects. Widen its allowedProjects (or bind a different key) and re-scan. See API keys.

Accounts & limits

What are the default limits? Typically 5 projects, 100 documents per project, 100,000 vectors, 10 MB chat attachments, and 100 MB knowledge-base uploads. A private deployment may differ. See Register & sign in.
