Notes for using gemma2-instruct

• This model is a nice small memory efficient model which is fast and does a decent job at generating aesthetically pleasing prompts.

• This model has 2B and a 9B option, I used the 9B during my testing.

• Keep max tokens 80, the max token length for SDXL prompt is 77 tokens but only 75 tokens are usable.
