Default model for Open AI and RetrievalQAChain

[nnduc1994]

What is the default model for openAI instance?

I am playing around with langchain / vector embedding. Right now, I am using RetrievalQAChain to answer questions from an embedded document(s).
const qaChain = RetrievalQAChain.fromLLM(llm, vectorStore.asRetriever())

Here is how I innit an openAI instance

 const llm = new OpenAI({
  openAIApiKey,
  temperature: 1,
  verbose: true
})

When looking at the Usage page in the OpenAI dashboard I saw there are calls used text-davinci, which I can't find on openAI pricing page for cost calculation purpose.

you can call the model you want in the openAI, just add,
modelName: 'text-davinci-003',
