Learn everything you need to know about OpenAI's new Responses API, which will replace both the Completions and Assistance APIs in the near future. This comprehensive Python tutorial guides you through setting up the SDK, sending messages to both chat and reasoning models, working with multimodal inputs, managing conversation history through stateful interactions, implementing structured output, and utilizing built-in tools like file search, web search, and computer use. Discover how to create AI agents with custom function tools and give them browser control using the computer use tool. This video covers model selection, system instructions, streaming responses, input formatting, reasoning models with adjustable effort levels, and essential implementation details to help you build advanced AI applications with OpenAI's most powerful interface for generating model responses.
