How does one count token usage using OpenAIChat?

[vinpac]

Hi,

I'm using the ChatOpenAI but I can't find how to get the token usage.

   const openai = new ChatOpenAI({})
   const message = await openai.call( ... )
   const tokenUsage = ?

• I couldn't find anything on Google or Docs or Stack overflow. Just found for python.

Please, send help!

you can use the verbose= true, it will return you the token usage
const openai = new ChatOpenAI({
verbose: true,
});
