Ballerina OpenAI Finetunes connector
Overview
OpenAI, an AI research organization focused on creating friendly AI for humanity, offers the OpenAI API to access its powerful AI models for tasks like natural language processing and image generation.
The ballarinax/openai.finetunes
package offers APIs to connect and interact with the fine-tuning related endpoints of OpenAI REST API v1 allowing users to customize OpenAI's AI models to meet specific needs.
Setup guide
To use the OpenAI Connector, you must have access to the OpenAI API through a OpenAI Platform account and a project under it. If you do not have a OpenAI Platform account, you can sign up for one here.
Create a OpenAI API Key
-
Open the OpenAI Platform Dashboard.
-
Navigate to Dashboard -> API keys <img src=https://raw.githubusercontent.com/ballerina-platform/module-ballerinax-openai.finetunes/main/docs/setup/resources/navigate-api-key-dashboard.png alt="OpenAI Platform" style="width: 70%;">
-
Click on the "Create new secret key" button <img src=https://raw.githubusercontent.com/ballerina-platform/module-ballerinax-openai.finetunes/main/docs/setup/resources/api-key-dashboard.png alt="OpenAI Platform" style="width: 70%;">
-

Quickstart
To use the OpenAI Finetunes
connector in your Ballerina application, update the .bal
file as follows:
Step 1: Import the module
Import the openai.finetunes
module.
import ballerinax/openai.finetunes;
import ballerina/io;
Step 2: Instantiate a new connector
Create a finetunes:ConnectionConfig
with the obtained API Key and initialize the connector.
configurable string token = ?;
final finetunes:Client openAIFinetunes = check new({
auth: {
token
}
});
Step 3: Invoke the connector operation
Now, utilize the available connector operations.
Note: First, create a sample.jsonl file in the same directory. This file should contain the training data formatted according to the guidelines provided here.
Fine tuning the gpt-3.5-turbo model
public function main() returns error? {
finetunes:CreateFileRequest req = {
file: {fileContent: check io:fileReadBytes("sample.jsonl"), fileName: "sample.jsonl"},
purpose: "fine-tune"
};
finetunes:OpenAIFile fileRes = check openAIFinetunes->/files.post(req);
string fileId = fileRes.id;
finetunes:CreateFineTuningJobRequest fineTuneRequest = {
model: "gpt-3.5-turbo",
training_file: fileId
};
finetunes:FineTuningJob fineTuneResponse =
check openAIFinetunes->/fine_tuning/jobs.post(fineTuneRequest);
}
Step 4: Run the Ballerina application
bal run
Examples
The OpenAI Finetunes
connector provides practical examples illustrating usage in various scenarios. Explore these examples, covering the following use cases:
-
Sarcastic bot - Fine-tune the GPT-3.5-turbo model to generate sarcastic responses
-
Sports headline analyzer - Fine-tune the GPT-4o-mini model to extract structured information (player, team, sport, and gender) from sports headlines.
