Qwen2.5-7B-Instruct-OpenVINO-INT4

This repository contains an optimized OpenVINO™ IR version of Alibaba Cloud's Qwen2.5-7B-Instruct, quantized to INT4 precision using NNCF. It is designed for high-performance reasoning and tool-calling on local Windows workstations.

🐍 Python Inference (Optimum-Intel)

To run this model locally using the optimum-intel library:

from optimum.intel import OVModelForCausalLM
from transformers import AutoTokenizer

model_id = "CelesteImperia/Qwen2.5-7B-Instruct-OpenVINO-INT4"
tokenizer = AutoTokenizer.from_pretrained(model_id)
model = OVModelForCausalLM.from_pretrained(model_id)

prompt = "Write a high-performance C# interface for an AI-driven factory system."
messages = [
    {"role": "user", "content": prompt},
]
input_ids = tokenizer.apply_chat_template(messages, add_generation_prompt=True, return_tensors="pt")

outputs = model.generate(input_ids, max_new_tokens=512)
print(tokenizer.decode(outputs[0], skip_special_tokens=True))

💻 For C# / .NET Users (LLamaSharp Implementation)

using LLama.Common;
using LLama;

// 1. Initialize the OpenVINO Model for Qwen 2.5
var parameters = new ModelParams("path/to/openvino_model.xml")
{
ContextSize = 8192, // Qwen supports larger contexts
GpuLayerCount = 0
};

// 2. Load and Execute
using var weights = LLamaWeights.LoadFromFile(parameters);
using var context = weights.CreateContext(parameters);
var executor = new StatelessExecutor(weights, parameters);

// 3. Run Reasoning Task
var chatHistory = new ChatHistory();
chatHistory.AddMessage(AuthorRole.User, "How can I optimize this Qwen 7B model for my factory's local NPU?");

foreach (var text in executor.InferAsync(chatHistory, new InferenceParams { MaxTokens = 512 }))
{
Console.Write(text);
}
