Week 1

6-8 hours this week

  • Verify on the Microsoft exam and assessment lab retirement list that AI-102 retired on June 30, 2026 before spending money on any course
  • Download the AI-103 study guide and map its five skill areas against the six areas of the final AI-102 blueprint
  • Note the language shift: AI-103 expects Python development experience, where AI-102 accepted Python or C#
  • Create an Azure subscription and a Microsoft Foundry project, and confirm your region supports the models you want
  • Take the free practice assessment for AI-103 on Microsoft Learn and record the per-area result
Foundry fundamentals, resources and authentication
Week 2

8-10 hours this week

  • Create a Microsoft Foundry hub and project and deploy one model, noting quota and rate limit settings
  • Connect to the deployed model from Python using the Foundry SDK and again with a raw REST call
  • Switch the connection from an account key to a managed identity and confirm the keyless path works
  • Configure a private endpoint for the AI resource and verify public access is refused
  • Enable diagnostic settings and send resource logs to a Log Analytics workspace
Responsible AI, filters and guardrails
Week 3

8-10 hours this week

  • Configure content filters at the deployment level and test each severity threshold against sample prompts
  • Add a blocklist and confirm which requests it stops that the default filter allows through
  • Enable prompt shields and attempt a direct and an indirect prompt injection to see what is detected
  • Read the Microsoft responsible AI documentation on harm categories and write down the four categories and their severity levels
  • Run a safety evaluation against a set of prompts and read the resulting report
Generative AI with Azure OpenAI in Foundry Models
Week 4

9-11 hours this week

  • Deploy a chat completion model and a text embedding model and compare their pricing units
  • Write code that varies temperature, top-p, max tokens and stop sequences and observe the effect on output
  • Generate images with DALL-E and pass an image into a multimodal model to compare the two workflows
  • Build a prompt template with variables and reuse it across three different inputs
  • Fine-tune a small model on a labelled dataset and compare its output with the base model
Retrieval-augmented generation and Azure AI Search
Week 5

9-11 hours this week

  • Provision an Azure AI Search resource, create a data source, an index and an indexer over a document set
  • Add a skillset with a built-in skill and then a custom skill backed by an Azure Function
  • Configure semantic ranking and a vector field, then compare keyword, semantic and hybrid search results for the same query
  • Ground a chat model in the index and inspect the citations it returns
  • Configure a Knowledge Store projection and inspect the file, object and table outputs
Agents
Week 6

9-11 hours this week

  • Build a single agent with the Microsoft Foundry Agent Service, giving it one tool and one knowledge source
  • Add function calling with a schema you define, and handle the tool call round trip in code
  • Implement conversation memory and observe how it changes multi-turn behaviour
  • Build a two-agent orchestration where one agent delegates a subtask to another
  • Add an approval step before a state-changing tool runs, then trace the agent's decisions
Computer vision
Week 7

8-10 hours this week

  • Call Azure Vision in Foundry Tools with several visual feature combinations and read the JSON response field by field
  • Extract printed and handwritten text from the same document and compare the confidence scores
  • Train a custom image classification model and an object detection model on the same small dataset and compare precision and recall
  • Publish a custom vision model and consume it from code rather than the portal
  • Run a video through Azure AI Video Indexer and review the extracted insights
Language and speech
Week 8

9-11 hours this week

  • Run key phrase extraction, named entity recognition, sentiment analysis, language detection and PII detection against one text corpus
  • Translate a document with Azure Translator in Foundry Tools and compare it with an LLM translation of the same text
  • Implement text-to-speech and shape the output with Speech Synthesis Markup Language, adjusting prosody and pronunciation
  • Build a custom question answering project, add question and answer pairs, create a multi-turn prompt flow and publish it
  • Train a conversational language understanding model with intents, entities and utterances, then evaluate and deploy it
Document intelligence and content understanding
Week 9

8-10 hours this week

  • Run three prebuilt Document Intelligence models, including invoice and receipt, and read the confidence values on extracted fields
  • Label a small document set, train a custom model, test it and publish it
  • Build a composed model from two custom models and observe how routing works
  • Use Azure Content Understanding in Foundry Tools to produce structured and markdown outputs from the same document
  • Ingest an image, an audio file and a video through Content Understanding and compare the analyzer outputs
Operations, observability and cost
Week 10

8-10 hours this week

  • Set up tracing across a generative application and read the token analytics and latency breakdown
  • Configure quota and rate limits on a deployment and trigger a throttling response deliberately
  • Model the monthly cost of a RAG application, separating embedding, storage, query and completion costs
  • Add a model monitoring configuration that reports drift and grounding quality
  • Deploy a container image of an AI service to a local or edge target
Timed practice and exam mechanics
Week 11

8-10 hours this week

  • Retake the Microsoft Learn practice assessment under timed conditions and compare it with your week one baseline
  • Work through the Microsoft exam sandbox and interact with build list, hot area, drag and drop and case study question types
  • Practise locating three specific facts on learn.microsoft.com quickly, because the exam gives access to that domain but adds no extra time
  • Decide in advance where you would take a break, given that you cannot return to any question already viewed
  • Rewrite every missed practice question as a one-sentence rule about which service or parameter was correct
Weak area repair and booking
Week 12

8-10 hours this week

  • Spend the largest remaining block on generative AI and agentic solutions, which carry 30 to 35 percent of AI-103
  • Re-read the AI-103 study guide bullet list and tick off every item you have built at least once
  • Check the Microsoft Certification deals page for an exam and retake bundle before paying full price
  • Confirm your Microsoft Learn profile name matches your government-issued photo identification exactly
  • Book the exam and read Microsoft's exam duration and experience page so the seat time and break rules hold no surprises
