NEW Putting a Human in the Tool-Calling Loop

Putting a Human in the Tool-Calling Loop

Giving an AI the power to take action is easy. Making sure it doesn't do something you'll regret is another matter. Spring AI's new tool confirmation support gives you a chance to say 'yes' or 'no' before your AI assistant does something you can't undo.

NEW RAG Without the Plumbing Using Hosted File Search

RAG Without the Plumbing Using Hosted File Search

RAG is great at giving AI access to knowledge it wasn't trained on, but getting all the pieces in place can feel like assembling furniture with a hundred tiny screws. With OpenAI's hosted File Search tool, you can skip the assembly instructions and get straight to asking questions about your documents.
