How much does CoT Reasoning typically cost for frameworks like LlamaIndex?

I'm curious to know, based on your experience in production, how much does Chain-of-Though Reasoning typically cost in terms of tokens for frameworks like LlamaIndex, LangChain, CrewAI, etc.?

I understand it depends on many different factors including the complexity of the product and the architecture of the agents involved, but I'd love to hear about your experiences in creating real-world-class application.
