🧠 Model Details

• Model Type: Hybrid Language Model (Merged)
• Parent Models:
  • Phi-1
  • Phi-1.5
• Merging Technique: Linear Merge (MergeKit)

🎯 Intended Use

This model is intended for research and experimentation in hybrid model optimization. Potential use cases include:

• ✅ Text Generation
• ✅ Conversational AI
• ✅ Code Assistance
• ✅ Creative Writing
• ✅ Exploration of Model Merging Effects

⚠️ Limitations & Considerations

While Phi-Hybrid-1.5B enhances certain capabilities, it also inherits limitations from its parent models:

• ❌ May generate inaccurate or misleading information
• ⚠️ Potential for biased, offensive, or harmful content
• 🔄 Merging may introduce unpredictable behaviors
• 📉 Performance may vary across different tasks

🔬 Merging Process & Configuration

This is not a newly trained model, but rather a merge of existing models using the following configuration:

merge_method: linear
dtype: float16
models:
  - model: "microsoft/phi-1"
    parameters:
      t: 1.0
      weight: 0.6
  - model: "microsoft/phi-1_5"
    parameters:
      t: 1.0
      weight: 0.4
parameters:
  normalize: true
  int8_mask: false
layers:
  - pattern: "model.*"

🌍 Environmental Impact

By utilizing model merging rather than training from scratch, Phi-Hybrid-1.5B significantly reduces computational and environmental costs.

🚀 How to Use

from transformers import AutoModelForCausalLM, AutoTokenizer

model_name = "YourProfile/Phi-Hybrid-1.5B"
tokenizer = AutoTokenizer.from_pretrained(model_name)
model = AutoModelForCausalLM.from_pretrained(model_name)

# Example usage
prompt = "Explain the theory of relativity in simple terms."
inputs = tokenizer(prompt, return_tensors="pt")
outputs = model.generate(**inputs, max_length=200)
response = tokenizer.decode(outputs[0], skip_special_tokens=True)
print(response)
