Flarum AI auto-reply

KBExit

Looks like the AI reply breaks if you don't choose a specific model lol.
Witnessed this during both Gemini and OpenRouter. Had to completely delete the thread and start over.

MichaelBelgium

KBExit If no model is specified, it'll use a pre-defined/default one according to platform

And yeah, system prompt implementation is in the making

Mirzaagha

l write API Key Google (Gemini). And other options not write, be standart. But not working auto reply with asistant. And have a one question, gemini service is free?

KBExit

Mirzaagha you'll have to go on AI Studio to find that out since Google is always changing their services. To get it working, you need to assign it to a member in the forum and select the model you want to use.

KBExit

@MichaelBelgium is there anyway you can have it set so the AI doesn't mention digging further into some context? I only have the AI configured to reply to the topic start and it doesn't make any sense to have it ask for a follow up when it won't reply to it anyways lol.
Example:

If you'd like, I can pull up more context on past shutdowns or the budget process.

KBExit You need a system prompt for this. You can give your own forum-specific instructions this way.

KBExit

huseyinfiliz Yes I understand that, I have full control over the one that posts the original post, but the extension version here does not have that option in the extension settings lol.

KBExit

MichaelBelgium I understand that it should default. But on my sites when the field is empty, you can no longer open the posts. Says "Oops something went wrong." And cannot save the post at all but deleting it and starting over with a model selected.

MichaelBelgium

KBExit Can you reproduce it and share the steps with me? Maybe i can fix it

EDIT: i also just had a quick look and only claude and openai supports system prompts? Openai not even 100%, it's a developer prompt in stead

KBExit

MichaelBelgium yeah, I'll send you a link when I get the chance!
I would just support OpenRouter and then maybe just have a dropdown of supported models when you implement system prompts to mitigate that.

MichaelBelgium

Openrouter has a thing called presets which is where you would store your system prompt. In the extension settings you would set the preset as model

KBExit

MichaelBelgium setting preset and I get the oops error again.

Update, Preset apparently requires the @ in front of it too.
I'll keep the link up and not delete that post as it shows what happens when no model is selected too.

MichaelBelgium

KBExit It's just empty? Can't find much on that page, only some javascript error

What does your flarum logs say ? (storage/logs)

KBExit

MichaelBelgium yeah this is the problem I am facing every time I enable the AI Reply Extension and leave the model field blank.

KBExit I've had that error while testing, seems the API call failed and returned "null" and inserted that in the database/post. But that's not allowed

What platform are you using? I'm gonna try to replicate

KBExit

MichaelBelgium I've since switched to OpenRouter, but this instance happened on both Gemini and OpenRouter at this point.
Unless you mean something else in regards to Platform? MariaDB for SQL.

MichaelBelgium

KBExit No you were right, i was referring to the AI platform 😄

I'll investigate this further!

KBExit

MichaelBelgium lol, thanks!
