Or maybe you were still paying attention to the Meta Llama 3 released last week, but today Microsoft did something different and released a new Phi-3 series of models. The first wave of releases on Hugging face is the Phi-3-mini version with a parameter size of 3.8B. Phi-3-mini can not only run on traditional computing devices, but also on edge devices such as mobile devices and IoT devices. The Phi-3-mini release covers the traditional Pytorch model format, the quantized version of the gguf format, and the onnx-based quantized version. This also brings convenience to developers in different application scenarios. The content of this blog hopes to allow different developers to explore different model formats released by Phi-3-mini combined with different technical frameworks, so that everyone can inference Phi-3-mini first.
Use Semantic Kernel to access Phi-3-mini
In the Copilot application, we create applications through Semantic Kernel / LangChain. This type of application framework is generally compatible with Azure OpenAI Service / OpenAI models, and can also support open source models on Hugging face and local models. What should we do if we want to use Semantic Kernel to access Phi-3-mini? Using .NET as an example, we can combine it with the Hugging face Connector in Semantic Kernel. By default, it can correspond to the model id on Hugging face (the first time you use it, the model will be downloaded from Hugging face, which takes a long time). You can also connect to the built local service. Compared with the two, I recommend using the latter because it has a higher degree of autonomy, especially in enterprise applications.
From the figure accessing local services through Semantic Kernel can easily connect to the self-built Phi-3-mini model server. Here is the running result.

Call quantized models with Ollama or LlamaEdge
More users prefer to use quantized models to run models locally. Through Ollama/LM Studio, individual users can call different quantized models at will. I will first show how to use Ollama to call the Phi-3-mini quantization model
You can directly run ollama run phi3 or configure it offline using the following.
- Create a Modelfile
FROM {Add your gguf file path}
TEMPLATE """<|user|>
{{.Prompt}}<|end|>
<|assistant|>"""
PARAMETER stop <|end|>
PARAMETER num_ctx 4096
- Running in terminal
ollama create phi3mini -f Modelfile
ollama run phi3mini
Here is the running result.
Sample Code https://github.com/Azure-Samples/Phi-3MiniSamples/tree/main/ollama
I have always been a supporter of cross-platform applications. If you want to use gguf in the cloud and edge devices at the same time, LlamaEdge can be your choice. LlamaEdge can be understood as WasmEdge (WasmEdge is a lightweight, high-performance, scalable WebAssembly runtime suitable for cloud native, edge and decentralized applications. It supports serverless applications, embedded functions, microservices, smart contracts and IoT devices. You can deploy gguf's quantitative model to edge devices and the cloud through LlamaEdge.
Here are the steps to use
- Install and download related libraries and files.
curl -sSf https://raw.githubusercontent.com/WasmEdge/WasmEdge/master/utils/install.sh | bash -s -- --plugin wasi_nn-ggml
curl -LO https://github.com/LlamaEdge/LlamaEdge/releases/latest/download/llama-api-server.wasm
curl -LO https://github.com/LlamaEdge/chatbot-ui/releases/latest/download/chatbot-ui.tar.gz
tar xzf chatbot-ui.tar.gz
Note: llama-api-server.wasm and chatbot-ui need to be in the same directory
- Run scripts in terminal
wasmedge --dir .:. --nn-preload default:GGML:AUTO:{Your gguf path} llama-api-server.wasm -p phi-3-chat
Here is the running result.

Run an ONNX quantized model
ONNX Runtime is an efficient runtime library for ONNX models. It supports multiple operating systems and hardware platforms, including CPU, GPU, etc. The key advantages of ONNX Runtime are its efficient performance and ease of deployment. Through ONNX Runtime, developers can easily deploy trained models to production environments without caring about the underlying inference framework. In the era of large models, ONNX Runtime has released an interface (Python/.NET/C/C++) based on generative AI. We can use this interface to call the Phi-3-mini model. Next we try to call the Phi-3-mini model through Python (when using ONNX Runtime Generative AI, you need to compile the environment first, please refer to https://github.com/microsoft/onnxruntime-genai/blob/main/examples/python/phi-3-tutorial.md)
Sample Code https://github.com/Azure-Samples/Phi-3MiniSamples/tree/main/onnx
Summary
The release of Phi-3-mini allows individuals and enterprises to deploy SLM on different hardware devices, especially mobile devices and industrial IoT devices that can complete simple intelligent tasks under limited computing power. Combining LLMs can open up a new era of Generative AI. Inference is only the first step. I hope you will continue to pay attention to the content of this series.
