Will RAG be replaced by tool calling?

[xCodehunter]

I just wanted to know whether what difference it makes with these two because more over tool calling is better to get real time data.

And too if anyone has any idea of a product or service please do let me know because I am suffering from getting ideas.

You can and should use both at the same time in your application. (e.g. use a tool call to determine if a call to a RAG workflow is necessary)

Do you have any ideas on it for build some kind of SaaS product? And is it risky building a saas product upon a product?
