This model was merged using the task arithmetic merge method using Delta-Vector/Holland-4B-V1 as a base.
The following models were included in the merge:
The following YAML configuration was used to produce this model:
base_model: Delta-Vector/Holland-4B-V1
dtype: bfloat16
merge_method: task_arithmetic
parameters:
normalize: false
slices:
- sources:
- layer_range: [0, 32]
model: Delta-Vector/Holland-4B-V1
- layer_range: [0, 32]
model: NewEden/Holland-V2
parameters:
weight: 0.50
- layer_range: [0, 32]
model: anthracite-org/magnum-v2-4b
