Are LLMs not giving you the desired answers so you keep burning tokens?

I am observing a pattern where the AI models wants you to keep interacting with them until you hit the limit. Especially, with claude, it tries to give long answers and redundant information and doesn’t follow the exact context! GPT 5.5 seems to be more efficient in answering but still far from one-shot answers! Also, the typical prompt practices like defining the role, giving examples, etc doesn’t lead to good results in one go! The models tend to keep the interaction alive, expand context or over contextualize. Are there any proven prompting techniques to break such patterns?
