gemma3-faces_ft-2

⚠️ warning: this model might generate potentially harmful content - for research purposes only

this model is a finetune of google/gemma-3-4b-it on the idhant297/faces-vision-alignment dataset.

for finetuning, first 1500 rows of the dataset are used.

the weights are from the last checkpoint of the training, i.e. step 188.
