Prompt Engineering: From Zero to Hero

I am sorry to be the bearer of bad news, but the AI hype train has already left prompt engineering in the dust and driven on to the great central context engineering station.
dSebastien•8h ago
The main problem with books lagging behind "now" is almost solved
tptacek•8h ago
I don't think this is generally true, though maybe I'm just missing the semantic drift. "Context engineering" as I'm familiar with it is something you do when you're building your own agent loops, not simply strategies for how to get the best response from a chatbot.
tehemperorer•7h ago
The chatbot forgets once the context tokens are used up. How do you engineer a solution, then, that ensures that the chatbot never forgets?
InterviewFrog•7h ago
"Context Engineering" is all the rage now. Picked up by AI Influencers.

Basically you give context to the AI models. Like if you want to build a social network you give the AI all the documentation around it so it can follow the best practices and guidelines etc.

I'm confused, where's the content?

For instance I looked in Meta-Cognitive Techniques and it mentions "Articles in This Series" but the list doesn't have any links...?

Prompt engineering was never a thing, sorry. Anyone that got paid as one certainly rode the hype train funded by people who didn't understand what they were paying for.
