For me, the problem comes from the fact that you haven't selected a model. You need to download a model from ollama, for example: ollama run mistral. Then use it on comfyui in selected_model in IF Chat Prompt.

if-ai commented 5 months ago

yes as @ThomasRoyer24 said you need to install ollama or use any of the other engines on the repo there are YT video guides on how to do it. but essentially you go to https://ollama.com/ download and install ollama for your system then open terminal or command prompt and typeollama run impactframes/llama3_ifai_sd_prompt_mkr_q4km this will install the main recommended model to work with SD prompts there are several great models you can use in your computer for working with images you can useollama run llava-llama3 to install after that restart comfy the models should appear in the dropdown menu
