COOOOL，有没有一个问题平均需要token的估计？

COOOOL，有没有一个问题平均需要token的估计？

这个要和你使用的参数来定，我更新了一个版本，可以计算每次计算消耗的 Token。
针对如下参数：

response_mode="tree_summarize",
similarity_top_k=3,
mode="embedding",

的情况下，每次问题估计消耗 10000 token，也就是相当于 $0.02 = 0.14 元人民币。
如果将 similarity_top_k 改成默认值 1，那么价格将会降低为原来的 1/3。

I did not know what to do, would u please help me with these error?

llama_index 0.5 have API broken!!!
so you can use pip install llama_index==0.4.40 .

TypeError: init() got an unexpected keyword argument 'llm_predictor'

抱歉，因为 llama_index 对API在小版本升级的时候 Break的不专业行为，已经弃用，建议使用Langchain。 YakShaver ***@***.***>于2023年4月27日 周四15:55写道：
