Step-by-step: Integrate Ollama Web UI to use Azure Open AI API with LiteLLM Proxy
Introductions Ollama WebUI is a streamlined interface for deploying and interacting with open-source large language models (LLMs) like Llama 3 and Mistral, enabling users to manage models, test them via a ChatGPT-like chat environment, and integrate them into applications through Ollama’s local API. While it excels for self-hosted models on platforms like Azure VMs, it does not natively support Azure OpenAI API endpoints—OpenAI’s proprietary models (e.g., GPT-4) remain accessible only through OpenAI’s managed API. However, tools like LiteLLM bridge this gap, allowing developers to combine Ollama-hosted models with OpenAI’s API in hybrid workflows, while maintaining compliance and cost-efficiency. This setup empowers users to leverage both self-managed open-source models and cloud-based AI services. Problem Statement As of February 2025, Ollama WebUI, still do not support Azure Open AI API. The Ollama Web UI only support self-hosted Ollama API and managed OpenAI API service (PaaS). This will be an issue if users want to use Open AI models they already deployed on Azure AI Foundry. Objective To integrate Azure OpenAI API via LiteLLM proxy into with Ollama Web UI. LiteLLM translates Azure AI API requests into OpenAI-style requests on Ollama Web UI allowing users to use OpenAI models deployed on Azure AI Foundry. If you haven’t hosted Ollama WebUI already, follow my other step-by-step guide to host Ollama WebUI on Azure. Proceed to the next step if you have Ollama WebUI deployed already. Step 1: Deploy OpenAI models on Azure Foundry. If you haven’t created an Azure AI Hub already, search for Azure AI Foundry on Azure, and click on the “+ Create” button > Hub. Fill out all the empty fields with the appropriate configuration and click on “Create”. After the Azure AI Hub is successfully deployed, click on the deployed resources and launch the Azure AI Foundry service. To deploy new models on Azure AI Foundry, find the “Models + Endpoints” section on the left hand side and click on “+ Deploy Model” button > “Deploy base model” A popup will appear, and you can choose which models to deploy on Azure AI Foundry. Please note that the o-series models are only available to select customers at the moment. You can request access to the o-series models by completing this request access form, and wait until Microsoft approves the access request. Click on “Confirm” and another popup will emerge. Now name the deployment and click on “Deploy” to deploy the model. Wait a few moments for the model to deploy. Once it successfully deployed, please save the “Target URI” and the API Key. Step 2: Deploy LiteLLM Proxy via Docker Container Before pulling the LiteLLM Image into the host environment, create a file named “litellm_config.yaml” and list down the models you deployed on Azure AI Foundry, along with the API endpoints and keys. Replace "API_Endpoint" and "API_Key" with “Target URI” and “Key” found from Azure AI Foundry respectively. Template for the “litellm_config.yaml” file. model_list: - model_name: [model_name] litellm_params: model: azure/[model_name_on_azure] api_base: "[API_ENDPOINT/Target_URI]" api_key: "[API_Key]" api_version: "[API_Version]" Tips: You can find the API version info at the end of the Target URI of the model's endpoint: Sample Endpoint - https://example.openai.azure.com/openai/deployments/o1-mini/chat/completions?api-version=2024-08-01-preview Run the docker command below to start LiteLLM Proxy with the correct settings: docker run -d \ -v $(pwd)/litellm_config.yaml:/app/config.yaml \ -p 4000:4000 \ --name litellm-proxy-v1 \ --restart always \ ghcr.io/berriai/litellm:main-latest \ --config /app/config.yaml --detailed_debug Make sure to run the docker command inside the directory where you created the “litellm_config.yaml” file just now. The port used to listen for LiteLLM Proxy traffic is port 4000. Now that LiteLLM proxy had been deployed on port 4000, lets change the OpenAI API settings on Ollama WebUI. Navigate to Ollama WebUI’s Admin Panel settings > Settings > Connections > Under the OpenAI API section, write http://127.0.0.1:4000 as the API endpoint and set any key (You must write anything to make it work!). Click on “Save” button to reflect the changes. Refresh the browser and you should be able to see the AI models deployed on the Azure AI Foundry listed in the Ollama WebUI. Now let’s test the chat completion + Web Search capability using the "o1-mini" model on Ollama WebUI. Conclusion Hosting Ollama WebUI on an Azure VM and integrating it with OpenAI’s API via LiteLLM offers a powerful, flexible approach to AI deployment, combining the cost-efficiency of open-source models with the advanced capabilities of managed cloud services. While Ollama itself doesn’t support Azure OpenAI endpoints, the hybrid architecture empowers IT teams to balance data privacy (via self-hosted models on Azure AI Foundry) and cutting-edge performance (using Azure OpenAI API), all within Azure’s scalable ecosystem. This guide covers every step required to deploy your OpenAI models on Azure AI Foundry, set up the required resources, deploy LiteLLM Proxy on your host machine and configure Ollama WebUI to support Azure AI endpoints. You can test and improve your AI model even more with the Ollama WebUI interface with Web Search, Text-to-Image Generation, etc. all in one place.Build AI Agents with MCP Tool Use in Minutes with AI Toolkit for VSCode

The new Phi-4-mini and Phi-4-multimodal now support Function Calling. This feature enables the models to connect with external tools and APIs. By deploying Phi-4-mini and Phi-4-multimodal with Function Calling capabilities on edge devices, we can achieve local expansion of knowledge capabilities and enhance their task execution efficiency. This blog will focus on how to use Phi-4-mini's Function Calling capabilities to build efficient AI Agents on edge devices. What‘s Function Calling How it works First we need to learn how Function Calling works Tool Integration: Function Calling allows LLM/SLM to interact with external tools and APIs, such as weather APIs, databases, or other services. Function Definition: Defines a function (tool) that LLM/SLM can call, specifying its name, parameters, and expected output. LLM Detection: LLM/SLM analyzes the user's input and determines if a function call is required and which function to use. JSON Output: LLM/SLM outputs a JSON object containing the name of the function to call and the parameters required by the function. External Execution: The application executes the function call using the parameters provided by LLM/SLM. Response to LLM: Returns the output of Function Calling to LLM/SLM, and LLM/SLM can use this information to generate a response to the user. Application scenarios Data retrieval: convert natural language queries into API calls to fetch data (e.g., "show my recent orders" triggers a database query) Operation execution: convert user requests into specific function calls (e.g., "schedule a meeting" becomes a calendar API call) Computational tasks: handle mathematical or logical operations through dedicated functions (e.g., calculate compound interest or statistical analysis) Data processing: chain multiple function calls together (e.g., get data → parse → transform → store) UI/UX integration: trigger interface updates based on user interactions (e.g., update map markers or display charts) Phi-4-mini / Phi-4-multimodal's Function Calling Phi-4-mini / Phi-4-multimodal supports single and parallel Function Calling. Things to note when calling You need to define Tools in System to start single or parallel Function Calling If you want to start parallel Function Calling, you also need to add 'some tools' to the System prompt The following is an example Single Function Calling tools = [ { "name": "get_match_result", "description": "get match result", "parameters": { "match": { "description": "The name of the match", "type": "str", "default": "Arsenal vs ManCity" } } }, ] messages = [ { "role": "system", "content": "You are a helpful assistant", "tools": json.dumps(tools), # pass the tools into system message using tools argument }, { "role": "user", "content": "What is the result of Arsenal vs ManCity today?" } ] Full Sample : Click Parallel Function Calling AGENT_TOOLS = { "booking_fight": { "name": "booking_fight", "description": "booking fight", "parameters": { "departure": { "description": "The name of Departure airport code", "type": "str", }, "destination": { "description": "The name of Destination airport code", "type": "str", }, "outbound_date": { "description": "The date of outbound flight", "type": "str", }, "return_date": { "description": "The date of return flight", "type": "str", } } }, "booking_hotel": { "name": "booking_hotel", "description": "booking hotel", "parameters": { "query": { "description": "The name of the city", "type": "str", }, "check_in_date": { "description": "The date of check in", "type": "str", }, "check_out_date": { "description": "The date of check out", "type": "str", } } }, } SYSTEM_PROMPT = """ You are my travel agent with some tools available. """ messages = [ { "role": "system", "content": SYSTEM_PROMPT, "tools": json.dumps(AGENT_TOOLS), # pass the tools into system message using tools argument }, { "role": "user", "content": """I have a business trip from London to New York in March 21 2025 to March 27 2025, can you help me to book a hotel and flight tickets""" } ] Full sample : click Using Ollama and Phi-4-mini Function Calling to Create AI Agents on Edge Devices Ollama is a popular free tool for deploying LLM/SLM locally and can be used in combination with AI Toolkit for VS Code. In addition to being deployed on your PC/Laptop, it can also be deployed on IoT, mobile phones, containers, etc. To use Phi-4-mini on Ollama, you need to use Ollama 0.5.13+. Different quantitative versions are supported on Ollama, as shown in the figure below: Using Ollama, we can deploy Phi-4-mini on the edge, and implement AI Agent with Function Calling under limited computing power, so that Generative AI can be applied more effectively on the edge. Current Issues A sad experience - If you directly use the interface to try to call Ollama in the above way, you will find that Function Calling will not be triggered. There are discussions on Ollama's GitHub Issue. You can enter the Issue https://github.com/ollama/ollama/issues/9437. By modifying the Phi-4-mini Template on the ModelFile to implement a single Function Calling, but the call to Parallel Function Calling still failed. Resolution We have implemented a fix by making a adjustments to the template. We have improved it according to Phi-4-mini's Chat Template and re-modified the Modelfile. Of course, the quantitative model has a huge impact on the results. The adjustments are as follows: TEMPLATE """ {{- if .Messages }} {{- if or .System .Tools }}<|system|> {{ if .System }}{{ .System }} {{- end }} In addition to plain text responses, you can chose to call one or more of the provided functions. Use the following rule to decide when to call a function: * if the response can be generated from your internal knowledge (e.g., as in the case of queries like "What is the capital of Poland?"), do so * if you need external information that can be obtained by calling one or more of the provided functions, generate a function calls If you decide to call functions: * prefix function calls with functools marker (no closing marker required) * all function calls should be generated in a single JSON list formatted as functools[{"name": [function name], "arguments": [function arguments as JSON]}, ...] * follow the provided JSON schema. Do not hallucinate arguments or values. Do to blindly copy values from the provided samples * respect the argument type formatting. E.g., if the type if number and format is float, write value 7 as 7.0 * make sure you pick the right functions that match the user intent Available functions as JSON spec: {{- if .Tools }} {{ .Tools }} {{- end }}<|end|> {{- end }} {{- range .Messages }} {{- if ne .Role "system" }}<|{{ .Role }}|> {{- if and .Content (eq .Role "tools") }} {"result": {{ .Content }}} {{- else if .Content }} {{ .Content }} {{- else if .ToolCalls }} functools[ {{- range .ToolCalls }}{{ "{" }}"name": "{{ .Function.Name }}", "arguments": {{ .Function.Arguments }}{{ "}" }} {{- end }}] {{- end }}<|end|> {{- end }} {{- end }}<|assistant|> {{ else }} {{- if .System }}<|system|> {{ .System }}<|end|>{{ end }}{{ if .Prompt }}<|user|> {{ .Prompt }}<|end|>{{ end }}<|assistant|> {{ end }}{{ .Response }}{{ if .Response }}<|user|>{{ end }} """ We have tested the solution using different quantitative models. In the laptop environment, we recommend that you use the following model to enable single/parallel Function Calling: phi4-mini:3.8b-fp16. Note: you need to bind the defined Modelfile and phi4-mini:3.8b-fp16 together to enable this to work. Please execute the following command in the command line: #If you haven't downloaded it yet, please execute this command firstr ollama run phi4-mini:3.8b-fp16 #Binding with the adjusted Modelfile ollama create phi4-mini:3.8b-fp16 -f {Your Modelfile Path} To test the single Function Calling and Parallel Function Calling of Phi-4-mini. Single Function Calling Parallel Function Calling Full Sample in notebook The above example is just a simple introduction. As we move forward with the development we hope to find simpler ways to apply it on the edge, use Function Calling to expand the scenarios of Phi-4-mini / Phi-4-multimodal, and also develop more usecases in vertical industries.

In today's data-driven world, images have become a ubiquitous source of information. From social media feeds to medical imaging, we encounter and generate images constantly. Extracting meaningful insights from these visual data requires sophisticated analysis techniques. In this blog post let’s build an Image Analysis Application using the cutting-edge Phi-3 Vision model completely free of cost and on-premise environment using the VS Code AI Toolkit. We'll explore the exciting possibilities that this powerful combination offers. The AI Toolkit for Visual Studio Code (VS Code) is a VS Code extension that simplifies generative AI app development by bringing together cutting-edge AI development tools and models. I would recommend going through the following blogs for getting started with VS Code AI Toolkit. 1. Visual Studio Code AI Toolkit: How to Run LLMs locally 2. Visual Studio AI Toolkit : Building Phi-3 GenAI Applications 3. Building Retrieval Augmented Generation on VSCode & AI Toolkit 4. Bring your own models on AI Toolkit - using Ollama and API keys Setup VS Code AI Toolkit: Launch the VS Code application and Click on the VS Code AI Toolkit extension. Login to the GitHub account if not already done. Once ready, click on model catalog. In the model catalog there are a lot of models, broadly classified into two categories, Local Run (with CPU and with GPU) Remote Access (Hosted by GitHub and other providers) For this blog, we will be using a Local Run model. This will utilize the local machine’s hardware to run the Language model. Since it involves analyzing images, we will be using the language model which supports vision operations and hence Phi-3-Vision will be a good fit as its light and supports local run. Download the model and then further it will be loaded it in the playground to test. Once downloaded, Launch the “Playground” tab and load the Phi-3 Vision model from the dropdown. The Playground also shows that Phi-3 vision allows image attachments. We can try it out before we start developing the application. Let’s upload the image using the “Paperclip icon” on the UI. I have uploaded image of Microsoft logo and prompted the language model to Analyze and explain the image. Phi-3 vision running on local premise boasts an uncanny ability to not just detect but unerringly pinpoint the exact Company logo and decipher the name with astonishing precision. This is a simple use case, but it can be built upon with various applications to unlock a world of new possibilities. Port Forwarding: Port Forwarding, a valuable feature within the AI Toolkit, serves as a crucial gateway for seamless communication with the GenAI model. To do this, launch the terminal and navigate to the “Ports” section. There will be button “Forward a Port”, click on that and select any desired port, in this blog we will use 5272 as the port. The Model-as-a-server is now ready, where the model will be available on the port 5272 to respond to the API calls. It can be tested with any API testing application. To know more click here. Creating Application with Python using OpenAI SDK: To follow this section, Python must be installed on the local machine. Launch the new VS Code window and set the working directory. Create a new Python Virtual environment. Once the setup is ready, open the terminal on VS Code, and install the libraries using “pip”. pip install openai pip install streamlit Before we build the streamlit application, lets develop the basic program and check the responses in the VSCode terminal and then further develop a basic webapp using the streamlit framework. Basic Program Import libraries: import base64 from openai import OpenAI base64: The base64 module provides functions for encoding binary data to base64-encoded strings and decoding base64-encoded strings back to binary data. Base64 encoding is commonly used for encoding binary data in text-based formats such as JSON or XML. OpenAI: The OpenAI package is a Python client library for interacting with OpenAI's API. The OpenAI class provides methods for accessing various OpenAI services, such as generating text, performing natural language processing tasks, and more. Initialize Client: Initialize an instance of the OpenAI class from the openai package, client = OpenAI( base_url="http://127.0.0.1:5272/v1/", api_key="xyz" # required by API but not used ) OpenAI (): Initializes a OpenAI model with specific parameters, including a base URL for the API, an API key, a custom model name, and a temperature setting. This model is used to generate responses based on user queries. This instance will be used to interact with the OpenAI API. base_url = "http://127.0.0.1:5272/v1/": Specifies the base URL for the OpenAI API. In this case, it points to a local server running on 127.0.0.1 (localhost) at port 5272. api_key = "ai-toolkit": The API key used to authenticate requests to the OpenAI API. In case of AI Toolkit usage, we don’t have to specify any API key. The image analysis application will frequently deal with images uploaded by users. But to send these images to GenAI model, we need them in a format it understands. This is where the encode_image function comes in. # Function to encode the image def encode_image(image_path): with open(image_path, "rb") as image_file: return base64.b64encode(image_file.read()).decode("utf-8") Function Definition: def encode_image(image_path): defines a function named encode_image that takes a single argument, image_path. This argument represents the file path of the image we want to encode. Opening the Image: with open(image_path, "rb") as image_file: opens the image file specified by image_path in binary reading mode ("rb"). This is crucial because we're dealing with raw image data, not text. Reading Image Content: image_file.read() reads the entire content of the image file into a byte stream. Remember, images are stored as collections of bytes representing color values for each pixel. Base64 Encoding: base64.b64encode(image_file.read()) encodes the byte stream containing the image data into base64 format. Base64 encoding is a way to represent binary data using a combination of printable characters, which makes it easier to transmit or store the data. Decoding to UTF-8: .decode("utf-8") decodes the base64-encoded data into a UTF-8 string. This step is necessary because the OpenAI API typically expects text input, and the base64-encoded string can be treated as text containing special characters. Returning the Encoded Image: return returns the base64-encoded string representation of the image. This encoded string is what we'll send to the AI model for analysis. In essence, the encode_image function acts as a bridge, transforming an image file on your computer into a format that the AI model can understand and process. Path for the Image: We will use an image stored on our local machine for this section, while we develop the webapp, we will change this to accept it to what the user uploads. image_path = "C:/img.jpg" #path of the image here This line of code is crucial for any program that needs to interact with an image file. It provides the necessary information for the program to locate and access the image data. Base64 String: # Getting the base64 string base64_image = encode_image(image_path) This line of code is responsible for obtaining the base64-encoded representation of the image specified by the image_path. Let's break it down: encode_image(image_path): This part calls the encode_image function, which we've discussed earlier. This function takes the image_path as input and performs the following: Reads the image file from the specified path. Converts the image data into a base64-encoded string. Returns the resulting base64-encoded string. base64_image = ...: This part assigns the return value of the encode_image function to the variable base64_image. This section effectively fetches the image from the given location and transforms it into a special format (base64) that can be easily handled and transmitted by the computer system. This base64-encoded string will be used subsequently to send the image data to the AI model for analysis. Invoking the Language Model: This code tells the AI model what to do with the image. response = client.chat.completions.create( model="Phi-3-vision-128k-cpu-int4-rtn-block-32-acc-level-4-onnx", messages=[ { "role": "user", "content": [ { "type": "text", "text": "What's in the Image?", }, { "type": "image_url", "image_url": {"url": f"data:image/jpeg;base64,{base64_image}"}, }, ], } ], ) response = client.chat.completions.create(...): This line sends instructions to the AI model we're using (represented by client). Here's a breakdown of what it's telling the model: chat.completions.create: We're using a specific part of the OpenAI API designed for having a conversation-like interaction with the model. The ... part: This represents additional details that define what we want the model to do, which we'll explore next. Let's break down the details (...) sent to the model: 1) model="Phi-3-vision-128k-cpu-int4-rtn-block-32-acc-level-4-onnx": This tells the model exactly which AI model to use for analysis. In our case, it's the "Phi-3-vision" model. 2) messages: This defines what information we're providing to the model. Here, we're sending two pieces of information: role": "user": This specifies that the first message comes from a user (us). The content: This includes two parts: "What's in the Image?": This is the prompt we're sending to the model about the image. "image_url": {"url": f"data:image/jpeg;base64,{base64_image}"}: This sends the actual image data encoded in base64 format (stored in base64_image). In a nutshell, this code snippet acts like giving instructions to the AI model. We specify the model to use, tell it we have a question about an image, and then provide the image data itself. Printing the response on the console: print(response.choices[0].message.content) We asked the AI model "What's in this image?" This line of code would then display the AI's answer. Console response: Finally, we can see the response on the terminal. Now to make things more interesting, let’s convert this into a webapp using the streamlit framework. Recipe Generator Application with Streamlit: Now we know how to interact with the Vision model offline using a basic console. Let’s make things even more exciting by applying all this to a use-case which probably will be most loved by all those who are cooking enthusiasts!! Yes, let’s create an application which will assist in cooking by looking what’s in the image of ingredients! Create a new file and name is as “app.py” select the same. venv that was used earlier. Make sure the Visual studio toolkit is running and serving the Phi-3 Vision model through the port 5272. First step is importing the libraries, import streamlit as st import base64 from openai import OpenAI base64 and OpenAI is the same as we had used in the earlier section. Streamlit: This part imports the entire Streamlit library, which provides a powerful set of tools for creating user interfaces (UIs) with Python. Streamlit simplifies the process of building web apps by allowing you to write Python scripts that directly translate into interactive web pages. client = OpenAI( base_url="http://127.0.0.1:5272/v1/", api_key="xyz" # required by API but not used ) As discussed in the earlier section, initializing the client and configuring the base_url and api_key. st.title('Recipe Generator 🍔') st.write('This is a simple recipe generator application.Upload images of the Ingridients and get the recipe by Chef GenAI! 🧑🍳') uploaded_file = st.file_uploader("Choose a file") if uploaded_file is not None: st.image(uploaded_file, width=300) st.title('Recipe Generator 🍔'): This line sets the title of the Streamlit application as "Recipe Generator" with a visually appealing burger emoji. st.write(...): This line displays a brief description of the application's functionality to the user. uploaded_file = st.file_uploader("Choose a file"): This creates a file uploader component within the Streamlit app. Users can select and upload an image file (likely an image of ingredients). if uploaded_file is not None: : This conditional block executes only when the user has actually selected and uploaded a file. st.image(uploaded_file, width=300): If an image is uploaded, this line displays the uploaded image within the Streamlit app with a width of 300 pixels. In essence, this code establishes the basic user interface for the Recipe Generator app. It allows users to upload an image, and if an image is uploaded, it displays the image within the app. preference = st.sidebar.selectbox( "Choose your preference", ("Vegetarian", "Non-Vegetarian") ) cuisine = st.sidebar.selectbox( "Select for Cuisine", ("Indian","Chinese","French","Thai","Italian","Mexican","Japanese","American","Greek","Spanish") ) We use Streamlit's sidebar and selectbox features to create interactive user input options within a web application: st.sidebar.selectbox(...): This line creates a dropdown menu (selectbox) within the sidebar of the Streamlit application.The first argument, "Choose your preference", sets the label or title for the dropdown.The second argument, ("Vegetarian", "Non-Vegetarian"), defines the list of options available for the user to select (in this case, dietary preferences). cuisine = st.sidebar.selectbox(...): This line creates another dropdown menu in the sidebar, this time for selecting the desired cuisine.The label is "Select for Cuisine".The options provided include "Indian", "Chinese", "French", and several other popular cuisines. In essence, this code allows users to interact with the application by selecting their preferred dietary restrictions (Vegetarian or Non-Vegetarian) and desired cuisine from the dropdown menus in the sidebar. def encode_image(uploaded_file): """Encodes a Streamlit uploaded file into base64 format""" if uploaded_file is not None: content = uploaded_file.read() return base64.b64encode(content).decode("utf-8") else: return None base64_image = encode_image(uploaded_file) The same function of encode_image as discussed in the earlier section is being used here. if st.button("Ask Chef GenAI!"): if base64_image: response = client.chat.completions.create( model="Phi-3-vision-128k-cpu-int4-rtn-block-32-acc-level-4-onnx", messages=[ { "role": "user", "content": [ { "type": "text", "text": f"STRICTLY use the ingredients in the image to generate a {preference} recipe and {cuisine} cuisine.", }, { "type": "image_url", "image_url": {"url": f"data:image/jpeg;base64,{base64_image}"}, }, ], } ], ) print(response.choices[0].message.content) st.write(response.choices[0].message.content) else: st.write("Please upload an image with any number of ingridients and instantly get a recipe.") Above code block implements the core functionality of the Recipe Generator app, triggered when the user clicks a button labeled "Ask Chef GenAI!": if st.button("Ask Chef GenAI!"): This line checks if the user has clicked the button. If they have, the code within the if block executes. if base64_image: This inner if condition checks if a variable named base64_image has a value. This variable likely stores the base64 encoded representation of the uploaded image (containing ingredients). If base64_image has a value (meaning an image is uploaded), the code proceeds. client.chat.completions.create(...): Client that had been defined earlier interacts with the API . Here, it calls a to generate text completions, thereby invoking a small language model. The arguments provided specify the model to be used ("Phi-3-vision-128k-cpu-int4-rtn-block-32-acc-level-4-onnx") and the message to be completed. The message consists of two parts within a list: User Input: The first part defines the user's role ("user") and the content they provide. This content is an instruction with two key points: Dietary Preference: It specifies to "STRICTLY use the ingredients in the image" to generate a recipe that adheres to the user's preference (vegetarian or non-vegetarian, set using the preference dropdown). Cuisine Preference: It mentions the desired cuisine type (Indian, Chinese, etc., selected using the cuisine dropdown). Image Data: The second part provides the image data itself. It includes the type ("image_url") and the URL, which is constructed using the base64_image variable containing the base64 encoded image data. print(response.choices[0].message.content) & st.write(...): The response will contain a list of possible completions. Here, the code retrieves the first completion (response.choices[0]) and extracts its message content. This content is then printed to the console like before and displayed on the Streamlit app using st.write. else block: If no image is uploaded (i.e., base64_image is empty), the else block executes. It displays a message reminding the user to upload an image to get recipe recommendations. The above code block is the same as before except the we have now modified it to accept few inputs and also have made it compatible with streamlit. The coding is now completed for our streamlit application! It's time to test the application. Navigate to the terminal on Visual Studio Code and enter the following command, (if the file is named as app.py) streamlit run app.py Upon successful run, it will redirect to default browser and a screen with the Recipe generator will be launched, Upload an image with ingredients, select the recipe, cuisine and click on “Ask Chef GenAI”. It will take a few moments for delightful recipe generation. While generating we can see the logs on the terminal and finally the recipe will be shown on the screen! Enjoy your first recipe curated by Chef GenAI powered by Phi-3 vision model on local prem using Visual Studio AI Toolkit! The code is available on the following GitHub Repository. In the upcoming series we will explore more types of Gen AI implementations with AI toolkit. Resources: 1. Visual Studio Code AI Toolkit: Run LLMs locally 2.

As we have seen in past blog posts, AI toolkit supports a range of models using Github Marketplace of models. However, you might require support for external models hosted by Google, Anthropic and Open AI which are either not available in the Github catalog of models or might want to use the models served by Ollama. We will cover both of these scenarios in this blog post. OpenAI, Anthropic and Google Hosted models Once you click on the Model catalog window and selected the models hosted by Google, Anthropic and OpenAI, you should see the following models selected. Also, you can add your APIs keys to the model in the following way On the above models, you should click on the "Try in playground", just below the model name model card and you should be able to see the following dialog box on the top search bar of the VS Code window. Here I have clicked on the "Try it in playground" link for Anthropic Claude 3.5 Sonnet model Enter your API Key and you are good to go. Also, as you can see in the dropdown text, you can also edit or change the value later. Similarly, you can perform the same action for the Google and OpenAI hosted models. Once you have done this you are free to use these models in the playground and for using the other features of AI toolkit extension. Using models served by Ollama Several developers are also using Ollama to experiment and play with models using the command line. Ollama is an open-source AI tool that allows users to run large language models (LLMs) on their local systems. It's a valuable tool for industries that require data privacy, such as healthcare, finance, and government which might need locally hosted models. So, AI toolkit already supports some locally downloadable models such as those in the Phi-series by Microsoft or those by Mistral. Ollama supports a wider variety of models especially those from Meta's Llama series of LLMs and SLMs. The complete list of models currently supported by Ollama can be found at Ollama library. We will run ollama on windows and when you run ollama and see help command you get the following output. Once you have selected the model from the library, you can use the ollama pull or ollama run to download the model. The run command will download the model and then run it if it's not already downloaded. The pull command will just download the model from the repository. Since I want you show you a multimodal model that can be run locally, I will be go to the command line and download and run llama3.2-vision model. See the commands for the same below We can also list the models already downloaded. As you can see, I have downloaded and tried a bunch of models. It might take a bit of time to download the models based on the speed of your internet connection. As you can see some of the models are quite large downloads. Also, you might need to make sure you have enough RAM on your laptop or desktop to run the models. So now we have downloaded the models, and we have run the models. Now, let's see how we can access them in AI Toolkit for VSCode. Go to the My models window as seen below. Click on the '+' symbol as seen below in the screenshot. Once you click on this you will see a dropdown in search. Click on add an Ollama model You will now see the choice to either select a model from ollama library or a custom ollama endpoint. For the purposes of this tutorial, we will select models. Let's select Multimodal modal we downloaded earlier. We should see the models we had seen in ollama list command earlier. See below. Now we can select the checkbox alongside llama3.2-vision:latest and select okay. You should now see the model appear in the My Models window like below. You can now right click on it and start using the model by loading in the playground. Since this is a multimodal model, you can use it to generate text as below. The screenshot below shows the model loaded via ollama and at the same time you can see that it is has the clip symbol activated in the window. Since this is a multi-modal model, we can give it an image and ask it questions. Which is what we will do next. Next, now let's attach an image and ask it questions about this image. This might take a bit more time as it will need to analyze the image and answer any questions. Since it is a generative AI model it can give slightly different inputs when given the same image. I can also ask the models questions about the image, and it will use the information from the image - the objects shown, the relationship between the objects and its world knowledge from its training to answer the questions. For example, see the session below. So, as you can the AI toolkit can be a fantastic place to try out different models from various sources. Ollama is also a great tool to try pre-built models locally securely without sending your data to the cloud, which can make it suitable for air-gapped environments and data privacy sensitive industries like fintech, healthcare and government. You have greater control over the models and the environment and the data they run on. It is also possible to customize the models and then serve them via ollama. This helps you choose the best model for your AI application.

Fine-Tuning Phi-3.5 Model Fine-tuning a language model like Phi-3.5 is a crucial step in adapting it to perform specific tasks or cater to specific domains. This section will walk through what fine-tuning is, its importance in NLP, and how to fine-tune the Phi-3.5 model using Azure Model Catalog for different languages and tasks. We'll also explore a code example and best practices for evaluating and validating the fine-tuned model. What is Fine-Tuning? Fine-tuning refers to the process of taking a pre-trained model and adapting it to a specific task or dataset by training it further on domain-specific data. In the context of NLP, fine-tuning is often required to ensure that the language model understands the nuances of a particular language, industry-specific terminology, or a specific use case. Why Fine-Tuning is Necessary Pre-trained Large Language Models (LLMs) are trained on diverse datasets and can handle various tasks like text summarization, generation, and question answering. However, they may not perform optimally in specialized domains without fine-tuning. The goal of fine-tuning is to enhance the model's performance on specific tasks by leveraging its prior knowledge while adapting it to new contexts. Challenges of Fine-Tuning Resource Intensiveness: Fine-tuning large models can be computationally expensive, requiring significant hardware resources. Storage Costs: Each fine-tuned model can be large, leading to increased storage needs when deploying multiple models for different tasks. LoRA and QLoRA To address these challenges, techniques like LoRA (Low-rank Adaptation) and QLoRA (Quantized Low-rank Adaptation) have emerged. Both methods aim to make the fine-tuning process more efficient: LoRA: This technique reduces the number of trainable parameters by introducing low-rank matrices into the model while keeping the original model weights frozen. This approach minimizes memory usage and speeds up the fine-tuning process. QLoRA: An enhancement of LoRA, QLoRA incorporates quantization techniques to further reduce memory requirements and increase the efficiency of the fine-tuning process. It allows for the deployment of large models on consumer hardware without the extensive resource demands typically associated with full fine-tuning. from transformers import AutoModelForSequenceClassification, Trainer, TrainingArguments from peft import get_peft_model, LoraConfig # Load a pre-trained model model = AutoModelForSequenceClassification.from_pretrained("bert-base-uncased") # Configure LoRA lora_config = LoraConfig( r=16, # Rank lora_alpha=32, lora_dropout=0.1, ) # Wrap the model with LoRA model = get_peft_model(model, lora_config) # Define training arguments training_args = TrainingArguments( output_dir="./results", evaluation_strategy="epoch", learning_rate=2e-5, per_device_train_batch_size=16, per_device_eval_batch_size=16, num_train_epochs=3, ) # Create a Trainer trainer = Trainer( model=model, args=training_args, train_dataset=train_dataset, eval_dataset=eval_dataset, ) # Start fine-tuning trainer.train() This code outlines how to set up a model for fine-tuning using LoRA, which can significantly reduce the resource requirements while still adapting the model effectively to specific tasks. In summary, fine-tuning with methods like LoRA and QLoRA is essential for optimizing pre-trained models for specific applications in NLP, making it feasible to deploy these powerful models in various domains efficiently. Why is Fine-Tuning Important in NLP? Task-Specific Performance: Fine-tuning helps improve performance for tasks like text classification, machine translation, or sentiment analysis in specific domains (e.g., legal, healthcare). Language-Specific Adaptation: Since models like Phi-3.5 are trained on general datasets, fine-tuning helps them handle industry-specific jargon or linguistic quirks. Efficient Resource Utilization: Instead of training a model from scratch, fine-tuning leverages pre-trained knowledge, saving computational resources and time. Steps to Fine-Tune Phi-3.5 in Azure AI Foundry Fine-tuning the Phi-3.5 model in Azure AI Foundry involves several key steps. Azure provides a user-friendly interface to streamline model customization, allowing you to quickly configure, train, and deploy models. Step 1: Setting Up the Environment in Azure AI Foundry Access Azure AI Foundry: Log in to Azure AI Foundry. If you don’t have an account, you can create one and set up a workspace. Create a New Experiment: Once in the Azure AI Foundry, create a new training experiment. Choose the Phi-3.5 model from the pre-trained models provided in the Azure Model Zoo. Set Up the Data for Fine-Tuning: Upload your custom dataset for fine-tuning. Ensure the dataset is in a compatible format (e.g., CSV, JSON). For instance, if you are fine-tuning the model for a customer service chatbot, you could upload customer queries in different languages. Step 2: Configure Fine-Tuning Settings Select the Training Dataset: Select the dataset you uploaded and link it to the Phi-3.5 model. 2) Configure the Hyperparameters: Set up training hyperparameters like the number of epochs, learning rate, and batch size. You may need to experiment with these settings to achieve optimal performance. 3) Choose the Task Type: Specify the task you are fine-tuning for, such as text classification, translation, or summarization. This helps Azure AI Foundry understand how to optimize the model during fine-tuning. 4) Fine-Tuning for Specific Languages: If you are fine-tuning for a specific language or multilingual tasks, ensure that the dataset is labeled appropriately and contains enough examples in the target language(s). This will allow Phi-3.5 to learn language-specific features effectively. Step 3: Train the Model Launch the Training Process: Once the configuration is complete, launch the training process in Azure AI Foundry. Depending on the size of your dataset and the complexity of the model, this could take some time. Monitor Training Progress: Use Azure AI Foundry’s built-in monitoring tools to track performance metrics such as loss, accuracy, and F1 score. You can view the model’s progress during training to ensure that it is learning effectively. Code Example: Fine-Tuning Phi-3.5 for a Specific Use Case Here's a code snippet for fine-tuning the Phi-3.5 model using Python and Azure AI Foundry SDK. In this example, we are fine-tuning the model for a customer support chatbot in multiple languages. from azure.ai import Foundry from azure.ai.model import Model # Initialize Azure AI Foundry foundry = Foundry() # Load the Phi-3.5 model model = Model.load("phi-3.5") # Set up the training dataset training_data = foundry.load_dataset("customer_queries_dataset") # Fine-tune the model model.fine_tune(training_data, epochs=5, learning_rate=0.001) # Save the fine-tuned model model.save("fine_tuned_phi_3.5") Best Practices for Evaluating and Validating Fine-Tuned Models Once the model is fine-tuned, it's essential to evaluate and validate its performance before deploying it in production. Split Data for Validation: Always split your dataset into training and validation sets. This ensures that the model is evaluated on unseen data to prevent overfitting. Evaluate Key Metrics: Measure performance using key metrics such as: Accuracy: The proportion of correct predictions. F1 Score: A measure of precision and recall. Confusion Matrix: Helps visualize true vs. false predictions for classification tasks. Cross-Language Validation: If the model is fine-tuned for multiple languages, test its performance across all supported languages to ensure consistency and accuracy. Test in Production-Like Environments: Before full deployment, test the fine-tuned model in a production-like environment to catch any potential issues. Continuous Monitoring and Re-Fine-Tuning: Once deployed, continuously monitor the model’s performance and re-fine-tune it periodically as new data becomes available. Deploying Phi-3.5 Model After fine-tuning the Phi-3.5 model, the next crucial step is deploying it to make it accessible for real-world applications. This section will cover two key deployment strategies: deploying in Azure for cloud-based scaling and reliability, and deploying locally with AI Toolkit for simpler offline usage. Each deployment strategy offers its own advantages depending on the use case. Deploying in Azure Azure provides a powerful environment for deploying machine learning models at scale, enabling organizations to deploy models like Phi-3.5 with high availability, scalability, and robust security features. Azure AI Foundry simplifies the entire deployment pipeline. Set Up Azure AI Foundry Workspace: Log in to Azure AI Foundry and navigate to the workspace where the Phi-3.5 model was fine-tuned. Go to the Deployments section and create a new deployment environment for the model. Choose Compute Resources: Compute Target: Select a compute target suitable for your deployment. For large-scale usage, it’s advisable to choose a GPU-based compute instance. Example: Choose an Azure Kubernetes Service (AKS) cluster for handling large-scale requests efficiently. Configure Scaling Options: Azure allows you to set up auto-scaling based on traffic. This ensures that the model can handle surges in demand without affecting performance. Model Deployment Configuration: Create an Inference Pipeline: In Azure AI Foundry, set up an inference pipeline for your model. Specify the Model: Link the fine-tuned Phi-3.5 model to the deployment pipeline. Deploy the Model: Select the option to deploy the model to the chosen compute resource. Test the Deployment: Once the model is deployed, test the endpoint by sending sample requests to verify the predictions. Configuration Steps (Compute, Resources, Scaling) During deployment, Azure AI Foundry allows you to configure essential aspects like compute type, resource allocation, and scaling options. Compute Type: Choose between CPU or GPU clusters depending on the computational intensity of the model. Resource Allocation: Define the minimum and maximum resources to be allocated for the deployment. For real-time applications, use Azure Kubernetes Service (AKS) for high availability. For batch inference, Azure Container Instances (ACI) is suitable. Auto-Scaling: Set up automatic scaling of the compute instances based on the number of requests. For example, configure the deployment to start with 1 node and scale to 10 nodes during peak usage. Cost Comparison: Phi-3.5 vs. Larger Language Models When comparing the costs of using Phi-3.5 with larger language models (LLMs), several factors come into play, including computational resources, pricing structures, and performance efficiency. Here’s a breakdown: Cost Efficiency Phi-3.5: Designed as a Small Language Model (SLM), Phi-3.5 is optimized for lower computational costs. It offers competitive performance at a fraction of the cost of larger models, making it suitable for budget-conscious projects. The smaller size (3.8 billion parameters) allows for reduced resource consumption during both training and inference. Larger Language Models (e.g., GPT-3.5): Typically require more computational resources, leading to higher operational costs. Larger models may incur additional costs for storage and processing power, especially in cloud environments. Performance vs. Cost Performance Parity: Phi-3.5 has been shown to achieve performance parity with larger models on various benchmarks, including language comprehension and reasoning tasks. This means that for many applications, Phi-3.5 can deliver similar results to larger models without the associated costs. Use Case Suitability: For simpler tasks or applications that do not require extensive factual knowledge, Phi-3.5 is often the more cost-effective choice. Larger models may still be preferred for complex tasks requiring deep contextual understanding or extensive factual recall. Pricing Structure Azure Pricing: Phi-3.5 is available through Azure with a pay-as-you-go billing model, allowing users to scale costs based on usage. Pricing details for Phi-3.5 can be found on the Azure pricing page, where users can customize options based on their needs. Code Example: API Setup and Endpoints for Live Interaction Below is a Python code snippet demonstrating how to interact with a deployed Phi-3.5 model via an API in Azure: import requests # Define the API endpoint and your API key api_url = "https://<your-azure-endpoint>/predict" api_key = "YOUR_API_KEY" # Prepare the input data input_data = { "text": "What are the benefits of renewable energy?" } # Make the API request response = requests.post(api_url, json=input_data, headers={"Authorization": f"Bearer {api_key}"}) # Print the model's response if response.status_code == 200: print("Model Response:", response.json()) else: print("Error:", response.status_code, response.text) Deploying Locally with AI Toolkit For developers who prefer to run models on their local machines, the AI Toolkit provides a convenient solution.
