Hello, does anyone have an idea about

Open source LLMs are free 👀

But in general, agents can be more expensive to run because they tend to require a more powerful LLM.

Summarization can also be expensive since you're passing in a lot of content to the LLM = high token usage.

thank you so much for ur response

You could add this to your code and benchmark. Open source = Free...sometimes. If self hosted yes, if using another service, likely not.
