Building Custom Chat AI: A Comprehensive Guide for Developers
In today's rapidly evolving digital landscape, the integration of artificial intelligence (AI) into business operations has become a pivotal strategy for companies aiming to enhance their customer engagement and streamline their processes. This article delves into the foundational steps and considerations for developers embarking on the journey of building a custom chat AI for their company website. From understanding the core concepts of AI to selecting the right models and implementing effective prompt engineering techniques, this guide provides a comprehensive overview to help developers navigate the complexities of AI development. Whether you are a beginner or have some experience in the field, the insights shared here will equip you with the knowledge and tools needed to create a robust and efficient chat AI tailored to your business needs. A discussion will be held with https://www.linkedin.com/in/nityan/, Senior Cloud Advocate at Microsoft specializing in AI, and https://mvp.microsoft.com/en-US/MVP/profile/fe4dbe00-cdb0-ec11-983f-000d3a1017e3, a Chinese AI MVP, to delve into these critical topics. What are the first steps a developer should take when starting to build a custom chat AI for their company website? Nitya: If you are new to AI, start by familiarizing yourself with the core concepts and usage of AI models. A course like https://aka.ms/genai-beginnerscan be a great starting point. Next, get hands-on experience with models by trying out GitHub Models, which are free to use with just a GitHub account. This will help you build your intuition for model selection and prompt engineering. If you already have some experience, the initial steps to building a custom chat AI are as follows: Identify the use case and requirements (e.g., typical questions asked and valid responses). Choose a model to start prototyping (test the question with various models and compare results). If your chat AI is grounded in your data, identify the data sources and formats (where and what). Select an AI app template to jumpstart development and customize it with your model and data choices. How does understanding model choice impact the development of a custom chat AI? Nitya: Understanding model choice is crucial for developing a custom chat AI. It involves evaluating models based on three key factors: cost, customization, and performance. Customization: Start by identifying the task you want to execute (e.g., chat, image, embeddings, agents). Filter models that support this capability and validate them with a test prompt to ensure they fit your requirements. This process will narrow down your options from thousands to a few suitable models. Cost: Consider whether the model supports serverless deployments (pay-as-you-go, per token) or managed deployments (subscription-based, per VM). Evaluate costs not just for usage (chat completion) but also for end-to-end development (evaluations, iterative ideation). Performance: Assess models based on latency (e.g., chat completions vs. reasoning models) and the quality and safety of responses. Understand default model characteristics (model card) and perform custom evaluations to ensure quality for your desired prompts dataset. Can you explain the concept of prompt engineering and how it can be applied using GitHub models? Nitya: Prompt engineering involves guiding the model on how to process questions and generate responses to improve quality. Think of developers as teachers and models as students being taught to answer exam questions. Prompt engineering provides a rubric to guide models in giving relevant answers. This includes providing examples, creating personas (e.g., "answer politely using formal language"), defining output formats (e.g., "answer in 1-2 sentences", "reply with results in JSON format"), and configuring model parameters (e.g., temperature, stop-words, top-p, max tokens). When working with GitHub models, you can configure models using the https://github.com/marketplace/models or move to an IDE with the https://learn.microsoft.com/en-us/rest/api/aifoundry/modelinference/API, offering both low-code and code-first options for prompt engineering. What is retrieval augmented generation (RAG), and how does it enhance the ability to chat with data? Wei: https://learn.microsoft.com/en-us/azure/search/retrieval-augmented-generation-overview?tabs=docs involves grounding user questions in retrieved knowledge from private data sources to ensure responses are relevant to the application scenario. It works by wrapping the initial user prompt in a prompt template to create the final model prompt sent to the model. Thehttps://learn.microsoft.com/en-us/azure/search/retrieval-augmented-generation-overview?tabs=docs workflow includes retrieval of knowledge, augmentation of the prompt, and generation of the response. This dynamic process provides relevant grounding data and instructions to contextualize user questions for app-required responses. What are some practical tips for developers to streamline their end-to-end journey from catalog to cloud? Nitya: Here are three tips to get started: Model Selection: Use GitHub Models with diverse test prompts to build intuition for prompt engineering and model capabilities. Compare models side-by-side. Copilot Development: Start with an https://aka.ms/ai-apps. Deploy it to understand the application and its architecture before customizing it to your needs. Validate your development environment and get familiar with tools. Safety & Evaluation: Explore built-in content safety filters and evaluators in the Azure AI platform to understand metrics and effectiveness of your prompt engineering or RAG strategy. Use tracing and App Insights to monitor performance and cost. What are some common challenges developers might face when building a custom chat AI, and how can they overcome them? Nitya and Wei: There are many challenges we can think of - here are three that are important: App Architecture: Understand the app architecture for your scenario (e.g., RAG, multi-agent). Explore existing AI app templates to build intuition and customize one that fits your requirements. Model Choice: Choose models based on cost, quota availability, and flexibility for future configuration. Use the Azure AI model inference API to abstract provider-specific SDKs and decouple your code from your choice, allowing for easier model swaps later. Observability: Debug issues in app development or execution performance. Use platforms and tools that bring observability to the end-to-end workflow. Activate App Insights and use tracing tools to generate telemetry for insights locally or in production. What resources and samples are available for further exploration into this subject?
