AI ASSISTANT CAIDO - instance-ai/credits returns 500

[Joaquin_de_Santibane]

Hi support team,

I’m using the AI Assistant (Preview version) on my instance joaquinito2708.app.n8n.cloud and it’s not working: whenever I send any message it returns the error “Something went wrong before I could finish that response”.

When reviewing the network requests, I can see that the GET /rest/instance-ai/credits endpoint returns a 500 error, while all other calls (chat, threads, preferences, gateway/status) respond with 200. It seems like there’s an isolated issue with the AI credits verification on my account.

Any ideas

? Thanks.

Best regards,
Joaquín

Do you have any AI credits in the first place, @Joaquin_de_Santibane ?
n8n cloud only give you builder credit, not AI credit

This confirmed what I had suspected

@Ophir_Prusak

What you’ll need

• n8n version 2.29.7 or later
• An API key from an LLM provider (Anthropic, OpenAI, or OpenRouter).
  You bring your own key, so LLM usage is billed to you by your provider.

I was wrong

@Ophir_Prusak

Q. What LLM model does it use?
A. on n8n Cloud it currently uses opus 4.8 for most of the stuff.

Q. Can I enter my own LLM API key instead of using n8n credits on n8n Cloud?
A. Not yet, but it’s something we’re thinking about.

Possibly, or has your credit run out?

Ophir from n8n here.
This is a fix we’re working on right now.
When you run out of credits the error message right now is a generic message. We’re fixing it so it will specifically say you’re out of credits.
