# phase_f4b

This is a merge of pre-trained language models created using [mergekit](https://github.com/cg123/mergekit).

## Merge Details
### Merge Method

This model was merged using the [DARE TIES](https://arxiv.org/abs/2311.03099) merge method using [Qwen/Qwen2.5-7B-Instruct](https://huggingface.co/Qwen/Qwen2.5-7B-Instruct) as a base.

### Models Merged

The following models were included in the merge:
* ./outputs/phase_d/merged_model
* ./outputs/phase_e2b/merged_model

### Configuration

The following YAML configuration was used to produce this model:

```yaml
# F4-b: DARE-TIES Merge (Phase D 0.7 + E2-b 0.3)
# More conservative: Phase D dominant, E2-b as supplement
# Hypothesis: Lighter E2-b influence avoids ALF regression

models:
  - model: ./outputs/phase_d/merged_model
    parameters:
      density: 0.5
      weight: 0.7
  - model: ./outputs/phase_e2b/merged_model
    parameters:
      density: 0.5
      weight: 0.3
merge_method: dare_ties
base_model: Qwen/Qwen2.5-7B-Instruct
parameters:
  normalize: true
  int8_mask: true
dtype: bfloat16
