May I ask what hardware do you use to run this application? The community's about section mentioned that the pinned post had some info, but I couldn't find it..
I think it's that you need to be able to throw parallel processing at a lot of RAM. If you want to do that on a PC you need a GPU that has a lot of RAM, which you can only really buy as part of a beefy GPU. You can't buy a midrange GPU and duct tape DIMMs onto it.
The Apple Silicon architecture has an OK GPU in it, but because of how it's integrated with the CPU, all the RAM in the system is GPU RAM. So Apple Silicon Macs can really punch above their weight for AI applications, because they can use a lot more RAM.
May I ask what modela you use to generate these? I got DiffusionBee, and the two models it downloaded by default, while impressive on their own (I mean... text to images? Magic!), the results are nowhere near as good as your images.
It’s a merge of Realistic Vision 4, LazyMix+, and URPM with weighting towards realistic vision 4. There are probably better merges and maybe even better models to use, but these have helped me generate some realistic stuff. I also use a fair amount of experimenting with LoRas and Controlnets along with dynamic prompts to test variables (prompt components or parts).
