Because RAG-type applications have a larger number of input tokens, reducing the unit price of input tokens has a more pronounced cost optimization effect on RAG-type applications than on ordinary question-answering applications.

UnverifiedThe advantages of the RAG approach over full fine-tuning lie in lower cost, faster updates, and the ability to strictly control the information boundaries of AI responses.75% similarVerifiedThe output token unit price of large models is generally higher than that of input tokens.72% similarUnverifiedOutput Tokens are typically 2-4x more expensive than input Tokens because generation requires autoregressive decoding Token by Token, with each generated Token requiring a complete forward pass computation71% similarUnverifiedToken caching (Prompt Caching) is a cost-optimization mechanism in large model APIs; when the same prefix appears repeatedly across multiple requests, the computation result can be cached and charged at a lower rate.71% similarVerifiedIn API billing, the unit price of output tokens is generally higher than that of input tokens, because the generation process requires autoregressive inference token by token71% similar
