97
+ ## Findings:
98
+ [Current]
99
+ - Increasing epochs from 5 (previous) to 20 (current) sure made the fine-tuned appear to respond a lot better on Golaif Virus and Dr. Golaif Pootis.
100
+ - However, this looks like a solid example of overfitting. 2 of 3 responses (under 2nd query) are 100% identical to the dataset trained on, excluding the hallucinations from [/INST] onwards that somehow still exists.
