Fine Tune GPT3 for Code

Dependencies:

• GPT-3 from OpenAI
• yargs for command-line arguments
• TypeScript for Compiler API
• dotenv for loading environment variables

Install and Setup

npm install

You can store the api key in a .env file and control debug logging with the DEBUG environment variable.

OPENAI_API_KEY="YOUR_OPENAI_API_KEY_GOES_HERE"
DEBUG="true"

Dataset and TypeScript/JavaScript Code Parser

The dataset is in ./dataset.csv.

To produce more completions for the dataset, you can use the parser which will parse TypeScript and JavaScript:

# Parsing a directory of source code files
node index.js parse ./input

# Parsing the source code of finetune-gpt3-for-code
node index.js parse ./index.js

# Parsing individual source code files
node index.js parse /path/to/typescript/file.ts
node index.js parse /path/to/javascript/file.js

It will produce the following output that can be used to extend the dataset:

prompt,completion
for loop,"for (var i = 0; i < 10; i ++) {"
for loop,"for (var i = 0; i < 10; i ++) {
  console.log(i);
}"
print i,"console.log(i)"
function for printHelloWorld with one argument,"function printHelloWorld(name) {"
function for printHelloWorld with one argument,"function printHelloWorld(name) {
  console.log(`Hello ${name}`);
}"

Running the Code

Upload the dataset and create the fine-tuned model:

node index.js

Alternative way to upload the dataset:

node index.js upload

Listing the status of the fine-tuned models

List the status of the fine-tuning until the fine_tune_model field is no longer null

node index.js list

Creating a completion

Use the fine tune id as the model when it is ready

node index.js generate model-finetune-id prompt
