print(tokenizer.decode(outputs[0][inputs["input_ids"].shape[-1]:]))This is a merge of pre-trained language models created using mergekit.
This model was merged using the TIES merge method using Qwen/Qwen3-14B-Base as a base.
The following models were included in the merge:
The following YAML configuration was used to produce this model:
models:
- model: huihui-ai/Qwen3-14B-abliterated
parameters:
weight: 1
density: 1
merge_method: ties
base_model: Qwen/Qwen3-14B-Base
parameters:
weight: 1
density: 1
normalize: true
int8_mask: true
dtype: bfloat16
The abliteration and merge caused an issue where the <think> token would not always be properly selected. This was fixed by using the vector from Qwen/Qwen3-14B.
