messages = [
{"role": "user", "content": "Who are you?"},

This is a merge of pre-trained language models created using mergekit.
This model was merged using the linear merge method.
The following models were included in the merge:
The following YAML configuration was used to produce this model:
dtype: float16
merge_method: linear
slices:
- sources:
- layer_range: [0, 16] # Assuming the first half of the model is more general and can be reduced more
model: mistralai/Mistral-7B-Instruct-v0.2
parameters:
weight: 0.5 # Reduce the weight of the first half to make room for the second half
- layer_range: [16, 32] # Assuming the second half of the model is more specialized and can be reduced less
model: mistralai/Mistral-7B-Instruct-v0.2
parameters:
weight: 0.5 # Maintain the weight of the second half
