The Complete OpenAI API with Python Masterclass
Intermediate 10 hours English Completion Certificate Certificate
About this course
This course teaches the OpenAI API from authentication and basic completions through advanced features: function calling for structured outputs, embeddings for semantic search, the Assistants API for stateful conversations, and fine-tuning for domain-specific models.
Students build real applications throughout — a document Q&A system, a customer support bot, and an AI-powered data extraction pipeline — plus learn cost management and rate limit handling for production use.
