I have tried a number of models in Ollama. The first one I ran is selectable as a Conversation agent in Home Assistant. The ones I added later do not appear. I can question them via Ollama and they work fine.
Restarting Home Assistant doesn’t work.
Is Home Assistant fussy about the model you use or is there something else happening.
You have to add the ollama server again in the ollama integration for every model you have. After you add the address of the server It Will prompt you to select the model.
I did It Yesterday adding 4 models
