OpenAI Agents SDK for Beginners: Build GPT-4o Assistants with Function Calling and Tool OrchestrationThe Ultimate Step-by-Step Guide to Building Smart, Production-Ready AI Agents with Python and OpenAI's Assistants SDKReady to build real-world AI assistants using GPT-4o?This hands-on guide is the most
complete, beginner-friendly, and production-focused book available on OpenAI's official Agents SDK. Whether you're an aspiring developer or an automation engineer, you'll master everything from
function calling and tool orchestration to deployment and optimization-all with
practical code, real-world projects, and best practices.
What You'll Learn (A-Z Mastery)- Set up your environment with Python 3.12, Poetry, and the OpenAI SDK
- Understand GPT-4o's multi-modal capabilities and model selection
- Learn JSON Schema and function-calling architecture from scratch
- Build assistants with tool chaining, retries, caching, and memory
- Debug hallucinations, invocation errors, and SDK timeouts
- Create smart assistants like:
- Calculator Bot (deterministic math tool)
- Weather Agent (real-time API integration)
- Task Manager Bot (multi-turn planning + persistence)
- Enable streaming, SSE, WebSockets, and concurrency
- Optimize cost with prompt compression, caching, and model tuning
- Deploy with FastAPI, Docker, GitHub Actions, Vercel, and Fly.io
- Harden your agent with OAuth, rate-limiting, PII redaction, ISO/GDPR readiness
