How to use

Start with initializing the logger. Each logger with the same name is singleton.

import tokenlog

t_logger = tokenlog.getLogger('session_1', 'gpt-3.5-turbo') # write logger name and model name that you are using
q1 = t_logger.query('This is the query that you used in LLM') # log the query

t_logger.answer('This is an answer from LLM', q1) # log the answer

t_logger.get_token_usage() # get total token usage from all queries

t_logger.get_history() # get history of token usage

t_logger.clear() # clear all histories

Batch logging

You can log multiple queries and answers at once.

import tokenlog

t_logger = tokenlog.getLogger('session_2', 'gpt-3.5-turbo') # write logger name and model name that you are using
query_ids = t_logger.query_batch(['This is the query that you used in LLM', 'This is the second query'])
t_logger.query(['This is the first answer', 'This is the second answer'], query_ids)

Chat Support

We also support chat format logging. You can use the OpenAI type chat format.

import tokenlog

t_logger = tokenlog.getLogger('session_3', 'gpt-5')
chat1 = t_logger.query([
    {"role": "system", "content": "You are a helpful assistant."},
    {"role": "user", "content": "Who won the world series in 2020?"},
])
t_logger.chat([
    {"role": "assistant", "content": "The 2020 World Series was played at Globe Life Field in Arlington, Texas."}
], chat1)
