Q61: Which quantitative tools do AI developers use to measure disparate performance across demographic groups?
Developers evaluate models using Fairness Metrics (such as demographic parity, equal opportunity difference, and disparate impact) to ensure equitable performance across user groups.
- Fairness metrics measure statistical parity across subgroups.
- Ensures fairness is treated as a technical requirement alongside accuracy.
What technical metrics measure whether an AI model performs equitably across subgroups?
Q62: How does Copilot Chat assist developers during code refactoring?

- AI acts as a peer assistant, not an autonomous agent.
What role does the developer play under the 'Human-in-the-Loop' AI operational pattern?
Q67: What is 'Few-Shot Prompting' when framing requests for Copilot?
Few-Shot Prompting involves providing 1 to 3 concrete input/output examples within the prompt request to guide the model on desired format and structural conventions.
- Zero-Shot: No examples provided.
- Few-Shot: Provides explicit input/output examples to guide the model.
What defines Few-Shot Prompting in AI interaction?
Q68: What feature in VS Code allows developers to define system-level instructions for Copilot Chat (e.g., .github/copilot-instructions.md)?
Developers can add a .github/copilot-instructions.md file to repository roots to supply Custom Instructions that automatically attach to all Copilot Chat prompts for that project.
.github/copilot-instructions.md: Custom repo-level instructions.- Enforces project-wide guidelines across team members.
Which markdown file automatically attaches repository guidelines to all Copilot Chat prompts in VS Code?
