CoffeeMix is intended primarily for producing more cartoony, flatter anime pictures that tend to have more pronounced lineart and cel shading. This model is not intended for detailed illustrations so backgrounds will be on the simpler/cartoony side. It works best with simple, short prompts and I highly encourage trying fewer tokens(prompt length and embeddings) if you dislike the results. Use EasyNegative on negative prompt. VAE is baked-in. My recommended sampler is DPM++ 2M Karras with 20 sampling steps, but other samplers work just fine. Model is pretty sfw unless you add nsfw into positive prompt. https://civitai.com/models/40630/coffeemix
