If you've noticed that Vinci takes a few seconds to start replying, you're noticing something real. Here's what's happening and whether it's a problem.
A few seconds before the first word
Vinci typically takes 1–2 seconds before the first word appears on screen. This is normal and not a bug — it's the time needed to:
- Send your message to the model.
- Process it.
- Start streaming the response back to you.
This delay is baked into how the service works and affects everyone equally. You'll see this every time you send a message, and it's not something you can speed up on your end.
When slowness is a real issue
If you're seeing delays longer than 5–10 seconds, or if responses stop mid-stream, something else might be happening:
- Check your internet connection. A slow or unstable connection can make responses take longer.
- Try a different browser or device. Browser extensions can sometimes interfere.
- Refresh the page on the web app to clear any stuck connections.
The model is also thinking
Depending on your question, Vinci might also pause after you see the first words while it thinks through a harder problem. This is intentional — more complex questions get more thinking time.
Still feeling slow?
If responses are consistently taking a very long time or timing out, contact support with details about:
- What device and browser you're using.
- How long responses typically take (with an example of a simple question).
- Whether it's happening in the app or through the API.
A few seconds at the start is expected, but consistent slowness beyond that is worth investigating.
