How to apply custom instructions to a model to create a personality or agent?

[ricostap]

I have different AI agents created in Gemini and would like to access them through Alpaca. I don't mind re-creating them if necessary. I have not found a way to do either. I don't mind using other instances if necessary. Can some please advise?

Hello there and thanks for using Alpaca!

You can easily create custom agents by using the model manager, which is the UI that opens when you click the Brain 🧠 icon next to the model name in the home page.

You will notice that the manager features a model "creator", where you can pick a base model to build upon and add custom system instructions, a name, an image and even a custom voice for text to speech if you'd like!

Even chatting with this model in a live conversation is possible by using the all-new "Live Mode".

Have fun!

Thanks for answering but one small issue, I removed that button.

You can still create custom models for Ollama by right clicking an added model and selecting "create child", there you can create your own model based on an existing one, you can input context and files and change some parameters

Ooh right the model manager update came already out, my bad.

Do I understand correctly that custom instructions are not possible for Gemini? to a day well lived, Rico Stapel M: +66 8 66 900 444 WhatsApp | Line | WeChat

Yes, these options to create custom models are exclusive to Ollama, to get a similar result you can use system messages in a chat, to do that press alt+enter when sending the message or right click the send button.

Even so, Gemini has a limitation, it doesn't support real system messages so Alpaca does a hacky fix to make it work but it can be inconsistent.
