Hi and congratulations on this article. It covers many aspects of Agentic AI and I think I will have to read it a few more times to fully understand it.

I still haven’t managed to get rid of my doubts around prompt injection. Putting that aside, I also still need to understand how the cost of using these systems will actually be structured. Does it still make sense to talk about cost per token, or should we start talking about cost per outcome? And even if we accept that, should we then separate the cost between successful outcomes and retry cost?

Thanks again for the article, I’ll definitely read it again more carefully over the next few days!
