Build Your First Custom AI Agent: A Step-by-Step Walkthrough
AI conversations can feel like alphabet soup, but building a custom AI agent doesn’t have to. In this episode, we break down custom AI agent architecture end-to-end so you can make the right build decisions with confidence.
What you’ll learn
- The key layers of a custom AI agent: UI/interaction → hosting/orchestration → tools & memory → LLMs → monitoring
- The six core tech-stack decisions most teams must make to ship a custom agent
- A concrete example architecture: an agent that triages Zendesk tickets and takes actions in Salesforce
