Notes for using mistral-7b-instruct-v0.3
This model is a nice small memory efficient model which is fast and does a decent job at generating aesthetically pleasing prompts.
Keep max tokens 80, the max token length for SDXL prompt is 77 tokens but only 75 tokens are usable.
If you don't like the initial results increment the cache_buster before trying again.
