Overview
- Integrating OpenAI with AWS combines OpenAI's AI capabilities with AWS's scalable infrastructure. This guide will walk you through setting up such integration seamlessly.
Prerequisites
- Create an OpenAI account and obtain your API key from the OpenAI dashboard.
- Set up an Amazon Web Services account if you haven't already.
- Basic understanding of AWS services like Lambda and API Gateway.
Set Up AWS Lambda
- Go to the AWS Management Console.
- Navigate to the Lambda section and click on "Create Function".
- Select "Author from scratch". Assign a function name and choose a runtime, preferably Python 3.x for simplicity.
- Create a new role with basic Lambda permissions.
Write Lambda Function
- Upon creating the function, you'll be directed to the code editor. Here, you'll write the code to call OpenAI's API.
import json
import openai
import os
def lambda_handler(event, context):
openai.api_key = os.environ['OPENAI_API_KEY']
response = openai.Completion.create(
engine="text-davinci-003",
prompt=event['prompt'],
max_tokens=150
)
return {
'statusCode': 200,
'body': json.dumps(response['choices'][0]['text'])
}
- Make sure to handle exceptions and errors appropriately in a production environment.
Set Environment Variables
- Under your Lambda function settings, find "Environment Variables" and set your `OPENAI_API_KEY` with your OpenAI key.
Create API Gateway
- Navigate to API Gateway in the AWS Console. Click “Create API”. Choose "REST API" and then "Build".
- For "Create Resource", give your resource a name and enable "CORS". Next, create a "POST" method for this resource.
- Choose your Lambda function as the backend for the POST method. Deploy the API to a new stage.
Test the Setup
- After deploying, you'll receive an Endpoint URL. Use this URL to make POST requests from your application, sending prompts in the body of the request.
Secure the API
- Implement AWS IAM roles or use a usage plan with an API key to secure access to your API Gateway.
- Consider adding input validation within your Lambda to prevent injection attacks.
Monitor and Scale
- Enable CloudWatch logging to monitor requests to your Lambda function. This will help you troubleshoot and optimize your setup.
- If necessary, adjust your Lambda function’s memory and timeout settings to fit your workload demands.
