npm i openai-api

Usage

Initializing

constOpenAI=require('openai-api');// Load your key from an environment variable or secret management service// (do not include your key directly in your code)constOPENAI_API_KEY=process.env.OPENAI_API_KEY;constopenai=newOpenAI(OPENAI_API_KEY);

Completion API call

(async()=>{constgptResponse=awaitopenai.complete({engine: 'davinci',prompt: 'this is a test',maxTokens: 5,temperature: 0.9,topP: 1,presencePenalty: 0,frequencyPenalty: 0,bestOf: 1,n: 1,stream: false,stop: ['\n',"testing"]});console.log(gptResponse.data);})();

Example of a successful completion response:

{id: 'some-long-id',object: 'text_completion',created: 1616791508,model: 'davinci:2020-05-03',choices: [{text: " predicted text...",index: 0,logprobs: null,finish_reason: 'length'}]}

Search API call

(async()=>{constgptResponse=awaitopenai.search({engine: 'davinci',documents: ["White House","hospital","school"],query: "the president"});console.log(gptResponse.data);})();

Answers API call

(async()=>{constgptResponse=awaitopenai.answers({"documents": ["Puppy A is happy.","Puppy B is sad."],"question": "which puppy is happy?","search_model": "ada","model": "curie","examples_context": "In 2017, U.S. life expectancy was 78.6 years.","examples": [["What is human life expectancy in the United States?","78 years."]],"max_tokens": 5,"stop": ["\n","<|endoftext|>"],});console.log(gptResponse.data);})();

Classification API call

(async()=>{constgptResponse=awaitopenai.classification({"examples": [["A happy moment","Positive"],["I am sad.","Negative"],["I am feeling awesome","Positive"]],"labels": ["Positive","Negative","Neutral"],"query": "It is a raining day :(","search_model": "ada","model": "curie"});console.log(gptResponse.data);})();

Engines API call

(async()=>{constgptResponse=awaitopenai.engines();console.log(gptResponse.data);})();

Embeddings API call

Documentation: https://beta.openai.com/docs/api-reference/embeddings

(async()=>{constgptResponse=awaitopenai.embeddings({"engine": "text-similarity-babbage-001","input": ["A happy moment","I am sad.","I am feeling awesome"],});console.log(gptResponse.data);// see index.d.ts interface Embedding})();

Get number of tokens for string

Not supported as of 4/21. See issue #20

The token limit is 2048 for completions using the OpenAI API. This method allows you to get the number of tokens in your prompt. This is done offline (no API call is made).

openai.encode('This is an encoding test. Number of tokens is not necessarily the same as word count.').then((result)=>{console.log("Number of tokens for string:"+result.length);});
