Libraries

How to use Fu01978/Qwen2.5-1.5B-TIES-Merge with Transformers:

# Use a pipeline as a high-level helper
from transformers import pipeline

pipe = pipeline("text-generation", model="Fu01978/Qwen2.5-1.5B-TIES-Merge")
messages = [
    {"role": "user", "content": "Who are you?"},
]
pipe(messages)

# Load model directly
from transformers import AutoTokenizer, AutoModelForCausalLM

tokenizer = AutoTokenizer.from_pretrained("Fu01978/Qwen2.5-1.5B-TIES-Merge")
model = AutoModelForCausalLM.from_pretrained("Fu01978/Qwen2.5-1.5B-TIES-Merge")
messages = [
    {"role": "user", "content": "Who are you?"},
]
inputs = tokenizer.apply_chat_template(
	messages,
	add_generation_prompt=True,
	tokenize=True,
	return_dict=True,
	return_tensors="pt",
).to(model.device)

outputs = model.generate(**inputs, max_new_tokens=40)
print(tokenizer.decode(outputs[0][inputs["input_ids"].shape[-1]:]))

Qwen2.5-1.5B-TIES-Merge

This repository contains a 1.5 billion parameter model created by merging Qwen2.5-1.5B (Base) and Qwen2.5-1.5B-Instruct using the TIES (Trim, Elect Sign & Merge) method.

Model Highlights

Logic Stability: Uses TIES merging to resolve parameter conflicts, resulting in better arithmetic and reasoning than standard SLERP merges.
Architecture: 24 layers, 1.5B parameters.

The following models were included in the merge:

Configuration

The merge was performed using Mergekit. The following YAML configuration was used to produce this model:

models:
  - model: Qwen/Qwen2.5-1.5B
    parameters:
      density: 0.5
      weight: 0.5
  - model: Qwen/Qwen2.5-1.5B-Instruct
    parameters:
      density: 0.5
      weight: 0.5
merge_method: ties
base_model: Qwen/Qwen2.5-1.5B
parameters:
  normalize: true
dtype: bfloat16
