Qwen2.5-14B-Instruct_Function_Calling_xLAM

Qwen2.5-14B-Function-Calling-xLAM

This model is a fine-tuned version of Qwen/Qwen2.5-14B-Instruct trained on the Salesforce/xlam-function-calling-60k dataset using SFT with LoRA adapters.

Overview

Qwen2.5-14B-Function-Calling-xLAM is a language model optimized using SFT. Supervised Fine-Tuning (SFT) trains the model to follow instructions by learning from high-quality demonstration data.

Key Features

• High-Quality Fine-Tuning: Trained on N/A carefully curated examples
• Efficient Training: Uses LoRA (Low-Rank Adaptation) with 4-bit quantization
• Strong Performance: Achieves N/A token accuracy on evaluation set
• Optimized for Inference: Available in multiple formats including GGUF quantizations

Usage

Quick Start

from transformers import AutoModelForCausalLM, AutoTokenizer
import torch

model_id = "ermiaazarkhalili/Qwen2.5-14B-Function-Calling-xLAM"

tokenizer = AutoTokenizer.from_pretrained(model_id)
model = AutoModelForCausalLM.from_pretrained(
    model_id,
    torch_dtype=torch.bfloat16,
    device_map="auto"
)

messages = [
    {"role": "system", "content": "You are a helpful assistant."},
    {"role": "user", "content": "What is the sum of 2 + 2?"}
]

text = tokenizer.apply_chat_template(messages, tokenize=False, add_generation_prompt=True)
inputs = tokenizer(text, return_tensors="pt").to(model.device)

outputs = model.generate(**inputs, max_new_tokens=512, temperature=0.7, do_sample=True)
response = tokenizer.decode(outputs[0][inputs['input_ids'].shape[1]:], skip_special_tokens=True)
print(response)

Using Pipeline

from transformers import pipeline

generator = pipeline("text-generation", model="ermiaazarkhalili/Qwen2.5-14B-Function-Calling-xLAM", device_map="auto")
messages = [{"role": "user", "content": "Explain the concept of machine learning."}]
output = generator(messages, max_new_tokens=256, return_full_text=False)
print(output[0]["generated_text"])

4-bit Quantized Inference

from transformers import AutoModelForCausalLM, BitsAndBytesConfig
import torch

quantization_config = BitsAndBytesConfig(
    load_in_4bit=True,
    bnb_4bit_compute_dtype=torch.bfloat16,
    bnb_4bit_use_double_quant=True,
    bnb_4bit_quant_type="nf4"
)

model = AutoModelForCausalLM.from_pretrained(
    "ermiaazarkhalili/Qwen2.5-14B-Function-Calling-xLAM",
    quantization_config=quantization_config,
    device_map="auto"
)
