ChatGPT can now handle web searches and file searches natively through the Responses API. No more setting up separate Perplexity integrations or managing vector databases.
I built a complete example showing:
- How to configure the built-in web search tool
- Creating vector stores for file search
- Getting an AI agent to automatically choose which tool to use
- Testing with real questions (web search for sports records, file search for document data)
This is useful if you're:
- Building automation workflows with n8n, Make, or similar platforms
- Integrating ChatGPT into custom applications
- Exploring what the new API capabilities can do
The video goes step-by-step through setup and shows working examples. Would love to hear if anyone's already tried the Responses API and what you're building with it.
