Is there a way to count the number of tokens? Cognee

[nauanelinhares]

I'm looking for a way to achieve token counting functionality similar to what LangChain offers.

For example, using LangChain, I can pass a callback to an LLM instance (like the one shown below) to count the number of tokens used for a request, such as when creating a knowledge graph:

llm = ChatOpenAI(
    model="gpt-5-mini",
    api_key=os.getenv("OPENAI_API_KEY"),
    callbacks=[counter],
)

Does this library have a way to implement token counting or use something else? I haven't been able to find this option within the configuration, like in the set_llm_config method.

I found this interface, but it seems there isn't an implementation for OpenAI. Could you provide an example of how to use this (or a similar concrete implementation)?

Thanks!
