Evaluation Results

The following table shows the evaluation results on various benchmarks compared to the baseline (non-quantized) model.

How to Use

You can load the quantized model and tokenizer using the transformers library:

from transformers import AutoModelForCausalLM, AutoTokenizer

model_id = "NoorNizar/Phi-4-mini-instruct-WINT4"

model = AutoModelForCausalLM.from_pretrained(model_id, device_map="auto")
tokenizer = AutoTokenizer.from_pretrained(model_id)

# Example usage (replace with your specific task)
prompt = "Hello, world!"
inputs = tokenizer(prompt, return_tensors="pt").to(model.device)
outputs = model.generate(**inputs, max_new_tokens=50)
print(tokenizer.decode(outputs[0], skip_special_tokens=True))

Disclaimer

This model was quantized automatically using a script. Performance and behavior might differ slightly from the original base model.
