DeepSeek-R1 is very popular, and it can achieve the same capabilities as OpenAI o1 in advanced reasoning. Microsoft has also added DeepSeek-R1 models to Azure AI Foundry and GitHub Models. We can compare DeepSeek-R1 ith other available models through GitHub Models Playground Note This series revolves around deployment of SLMs to Edge Devices 'Edge AI' we will focus on the deployment advanced reasoning models, with different application scenarios. You can learn more in the following session AI Tour BRK453. In this experiement we want to deploy advanced reasoning models to the edge, so that they can run on edge devices with limited computing power and offline environments. At this time, the recommendation is to use the traditional ONNX model . We can use Microsoft Olive to convert the DeepSeek-R1 Distrill model. Getting started with Microsoft Olive is very straightforward. Install the Microsoft Olive library through the command line and Python 3.10+ (recommended) pip install olive-ai The DeepSeek-R1 Distrill model series has different parameters such as 1.5B, 7B, 8B, 14B, 32B, 70B, etc. This article is mainly based on the 1.5B, 7B, and 14B models (so a Small Language Model). CPU Inference Let's discuss 1.5B and 7B, which are models with lower parameter. We can directly use the CPU as computing for inference to test the effect (hardware environment Azure DevBox, AMD EPYC 7763 64-Core + 64GB Memory + 2T SSD) Quantization conversion olive auto-opt --model_name_or_path <Your DeepSeek-R1-Distill-Qwen-1.5B/7B local location> --output_path <Your Convert ONNX INT4 Model local location> --device cpu --provider CPUExecutionProvider --precision int4 --use_model_builder --log_level 1 You can download it directly from my Hugging face Repo (Note: This model is for testing and has not been fully tested by AI Content Safety or provided as an Offical Model) DeepSeek-R1-Distill-Qwen-1.5B-ONNX-INT4-CPU DeepSeek-R1-Distill-Qwen-7B-ONNX-INT4-CPU Running with ONNX Runtime GenAI Install ONNX Runtime GenAI and ONNX Runtime CPU support libraries pip install onnxruntime-genai pip install onnxruntime Sample Code https://github.com/kinfey/EdgeAIForAdvancedReasoning/blob/main/notebook/demo-1.5b.ipynb https://github.com/kinfey/EdgeAIForAdvancedReasoning/blob/main/notebook/demo-7b.ipynb Performance comparison 1.5B vs 7B We compare two different inference scenarios explain 1+1=2 1.5B quantized ONNX model memory occupied, time consumption and number of tokens generated: 7B quantized ONNX model memory occupied, time consumption and number of tokens generated 2. Find all pairwise different isomorphism groups with order 147 and no elements with order 49 1.5B quantized ONNX model memory occupied, time consumption and number of tokens generated: 7B quantized ONNX model memory occupied, time consumption and number of tokens generated Results of the numbers Through the test, we can see that the 1.5B model of DeepSeek is more suitable for use on CPU inference and can be deployed on traditional PCs or IoT devices. As for 7B, although it has better inference, it is not very effective on CPU operation. GPU Inference It is ideal if we have a GPU on the edge device. We can quantize and convert it to an ONNX model for CPU inference through Microsoft Olive. Of course, it can also be converted to a model for GPU inference. Here I take the 14B DeepSeek-R1-Distill-Qwen-14B as an example and make an inference comparison with Microsoft's Phi-4-14B Quantization conversion olive auto-opt --model_name_or_path <Your Phi-4-14B or DeepSeek-R1-Distill-Qwen-14B local path > --output_path <Your converted Phi-4-14B or DeepSeek-R1-Distill-Qwen-14B local path > --device gpu --provider CUDAExecutionProvider --precision int4 --use_model_builder --log_level 1 You can download it directly from my Hugging face Repo (Note: This model is for testing and has not been fully tested by AI Content Safety and not an Official Model) DeepSeek-R1-Distill-Qwen-14B-ONNX-INT4-GPU Phi-4-14B-ONNX-INT4-GPU Running with ONNX Runtime GenAI CUDA Install ONNX Runtime GenAI and ONNX Runtime GPU support libraries pip install onnxruntime-genai-cuda pip install onnxruntime-gpu Compare the results in the GPU environment with Gradio It is recommended to use a GPU with more than 8G memory To increase the comparison of the results, we compare it with Phi-4-14B-ONNX-INT4-GPU and DeepSeek-R1-Distill-Qwen-14B-ONNX-INT4-GPU to see the different results. We also show we use OpenAI o1-mini (it is recommended to use o1-mini through GitHub Models), Sample Code https://github.com/kinfey/EdgeAIForAdvancedReasoning/blob/main/notebook/Performance_AdvancedReasoning_ONNX_CPU.ipynb You can test any prompt on Gradio to compare the results of Phi-4-14B-ONNX-INT4-GPU, DeepSeek-R1-Distill-Qwen-14B-ONNX-INT4-GPU and OpenAI o1 mini. DeepSeek-R1 reduces the cost of inference models and produces more instructive results on professional problems, but Phi-4-14B also has advantages in reasoning and uses lower computing power to complete inference. As for OpenAI o1 mini, it is more comprehensive and can touch all problems. If you want to deploy to Edge Device, Phi-4-14B and quantized DeepSeek-R1 are good choices for you.

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.

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.

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.

Introduction Creating your own private ChatGPT allows you to leverage AI capabilities while ensuring data privacy and security. This guide walks you through building a secure, customized chatbot using tools like Azure OpenAI, Cosmos DB and Azure App service. Why Build a Private ChatGPT? With the rise of AI-driven applications, organizations, people often face challenges related to data privacy, customization, and integration. Building a private ChatGPT addresses these concerns by: Maintaining Data Privacy: Keep sensitive information within your infrastructure. Customizing Responses: Tailor the chatbot’s behavior and language to suit your requirements. Ensuring Security: Leverage enterprise-grade security protocols. Avoiding Data Sharing: Prevent your data from being used to train external models. If organizations do not take these measures their data may go into future model training and can leak your sensitive data to public. Eg: Chatgpt collects personal data mentioned in their privacy policy Prerequisites Before you begin, ensure you have: Access to Azure OpenAI Service. A development environment set up with Python. Basic knowledge of FastAPI and MongoDB. An Azure account with necessary permissions. If you do not have Azure subscription, try Azure for students for FREE. Step 1: Set Up Azure OpenAI Log in to the Azure Portal and create an Azure OpenAI resource. Deploy a model, such as GPT-4o (multimodal), and note down the endpoint and API key. Note there is also an option of keyless authentication. Configure permissions to control access. Step 2: Use Chatgpt like app sample You can select any repository to be as base template for your app, in this I will be using the third option AOAIchat. It is developed by me. GitHub - mckaywrigley/chatbot-ui: AI chat for any model. Azure-Samples/azure-search-openai-demo: A sample app for the Retrieval-Augmented Generation pattern running in Azure, using Azure AI Search for retrieval and Azure OpenAI large language models to power ChatGPT-style and Q&A experiences. sourabhkv/AOAIchat: Azure OpenAI chat This architecture diagram represents a typical flow for a private ChatGPT application with the following components: App UX (User Interface): This is the front-end application (mobile, web, or desktop) where users interact with the chatbot. It sends the user's input (prompt) and displays the AI's responses. App Service: Acts as the backend application, handling user requests and coordinating with other services. Functions: Receives user inputs and prepares them for processing by the Azure OpenAI service. Streams AI responses back to the App UX. Reads from and writes to Cosmos DB to manage chat history. Azure OpenAI Service: This is the core AI service, processing the user input and generating responses using models like GPT-4o. The App Service sends the user input (along with context) to this service and receives the AI-generated responses. Cosmos DB: A NoSQL database used to store and manage chat history. Operations: Writes user messages and AI-generated responses for future reference or analysis. Reads chat history to provide context for AI responses, enabling more intelligent and contextual conversations. Data Flow: User inputs are sent from the App UX to the App Service. The App Service forwards the input (with additional context, if needed) to Azure OpenAI. Azure OpenAI generates a response, which is streamed back to the App UX via the App Service. The App Service writes user inputs and AI responses to Cosmos DB for persistence. This architecture ensures scalability, secure data handling, and the ability to provide contextual responses by integrating database and AI services. What can you do with my template? AOAIchat supports personal, enterprise chat enabled by RAG People can enable RAG mode if they want to search within their database, else it behaves like normal ChatGPT. It supports multimodality, (supports image, text input) also depends on model deployed in Azure AI foundry. Step 3: Deploy to Azure Deploy a Cosmos DB account in nearest region Deploy Azure OpenAI model (gpt-4o, gpt-4o-mini recommended) Deploy Azure App service, try using container I would recommend B1plan to your nearest region, select docker registry sourabhkv/aoaichatdb:0.1 startup command uvicorn app:app --host 0.0.0.0 --port 80 After app service starts, put all environment variables The application requires the following environment variables to be set for proper configuration: Environment Variable Description AZURE_OPENAI_ENDPOINT The endpoint for Azure OpenAI API. AZURE_OPENAI_API_KEY API key for accessing Azure OpenAI. DEPLOYMENT_NAME Azure OpenAI deployment name. API_VERSION API version for Azure OpenAI. MAX_TOKENS Maximum tokens for API responses. MONGO_DETAILS MongoDB connection string. AZURE_OPENAI_ENDPOINT=<your_azure_openai_endpoint> AZURE_OPENAI_API_KEY=<your_azure_openai_api_key> DEPLOYMENT_NAME=<your_deployment_name> API_VERSION=<your_api_version> MAX_TOKENS=<max_tokens> MONGO_DETAILS=<your_mongo_connection_string> Optional feature: implement authentication to secure access. Within app service select Authentication and select service providers. I went with Entra based authentication with single tenant. There is option of multi-tenant, personal accounts as well. Restart App service and within 2 minutes your private ChatGPT is ready. Pricing Pricing may depend on the plan you have deployed resources and region. Check Azure calculator for price estimation. My estimate for pricing I deployed all my resources in Sweden central Cosmos DB config - Cosmos DB for MongoDB (RU) serverless config with single write master, 2 GB transactional storage, 2 backup plan (FREE) ~ 0.75$ Azure OpenAI service - plan S0, model gpt-4o-mini global deployment, Input 20000 tokens, Output 10000 tokens ~ 9.00$ App service plan - OS Linux, Tier B1, instance count 1 ~13.14$ Total monthly cost = 22.89$ This price may vary in future, in region I calculated my configuration in Azure calculator Governance Azure OpenAI provides content filters to block any kind of input that violates responsible AI practices. Categories include Hate and Fairness Sexual Violence Self-harm User Prompt Attacks (direct and indirect) The content filtering system detects and takes action on specific categories of potentially harmful content in both input prompts and output completions. Azure OpenAI Service includes default safety settings applied to all models set as medium. Content filters can be modified to different level depending on use case. It supports RAG, I have provided detailed solution for it in my GitHub. Practical implementation GE Aerospace, in partnership with Microsoft and Accenture, has launched a company-wide generative AI platform, leveraging Microsoft Azure and Azure OpenAI Service. This solution aims to transform asset tracking and compliance in aviation, enabling quick access to maintenance records and reducing manual processing time from days to minutes.
