Pinecone assistant used a lot of prompt token

Sorry for asking such questions, I’m a beginner.

I uploaded a rather big file with 16.000 characters and I think it’s the cause of the excessive tokens usage.

Do I have to divide the document into smaller chunks like what I did with the embeddings in the database? like for example, I divided the document into 30 smaller chunks with 500 words each and uploaded to the database, if I do the same with documents in the assistant, it’ll be 30 separated files

What is the proper way to reduce the usage of token?
