• Educating Business Stakeholders: Develop strategies to effectively communicate with business clients who might have partial or evolving technical understanding.

Assignments:

• Develop a basic AI agent capable of routing queries or tasks.
• Write two meaningful blog posts or articles on an AI tech topic requiring clear explanation.

Week 4: AI Application Observability and Deployment
