Two of them are listed on the Topic List Previews component Topic.
But they are not really set up as demos for this plugin so you may find the functionality limited or missing as a new user.
I would encourage you to go ahead and set it up on your instance. It doesn’t take that long.
Great I will look into it thank you Merefield
Meta has just released their new Llama 4 models.
Chatbot is capable of using them.
I’m using www.groq.com for this (no affiliation) which has already deployed their scout model 
(remember to supply their key).
(NB I wouldn’t yet recommend this in production if you are using Embeddings as that is only supported for OpenAI).
It’s getting exhausting keeping up with OpenAI 
https://openai.com/index/gpt-4-1/
https://openai.com/index/introducing-o3-and-o4-mini/
But I’ve updated Chatbot with support for these models (actually mostly a bugfix for reasoning models and updates to the model selections).
note that if you use reasoning, the new setting, chatbot_open_ai_model_reasoning_level, to influence amount of reasoning (reasoning models only). The higher the setting, the cleverer it gets, but watch those tokens and make sure you increase Chatbot max response tokens or you may get an error.
The reasoning models should now work with RAG properly.
If you intend to use the excellent gpt-4.1-nano make sure you activate the setting Chatbot API supports name attribute in order to get sensible responses.
If you use the new GPT 4.1 models, the context lengths can now be insane so you can increase the Chatbot max look behind to a large number
