Build an AWS Bedrock-Powered LLM API with Lambda & API Gateway – Fast Deployment with ChatGPT

In this video, we’ll walk through building a serverless LLM application using AWS Lambda, API Gateway, and Amazon Bedrock—with the help of ChatGPT at every step.

You'll learn how to:
✅ Use AWS CloudShell and AWS CLI to deploy Lambda functions
✅ Request access to Bedrock models like Llama 3
✅ Create and test an API endpoint that connects to a foundation model
✅ Use ChatGPT prompts to generate code and solve errors in real time

Whether you're new to AWS or want to build powerful AI apps faster, this hands-on tutorial will help you go from idea to deployed API in minutes.

Tools Used: AWS CloudShell, Lambda, API Gateway, Bedrock, ChatGPT

Prompts

"Give me a Lambda function to invoke an AWS Bedrock model. I will integrate Lambda with API Gateway, so ensure the function can be tested directly and also using API Gateway."

Deployment Prompt (CLI)

"Give me the AWS CLI command to deploy this Lambda function."

Role Creation Prompt

"I don’t have a Lambda execution role."

Testing Prompt

"Function created. How to test from Lambda UI?"

Model Access Prompt

"I have access to this model Llama 3.1 70B Instruct, so change the Lambda code."

Test Event Prompt

"Give JSON to test."

API Gateway Setup Prompt

"Now help me create an API Gateway endpoint and give instructions to test also using CLI."

Validation Prompt

"Is API Gateway pointing to this function?"

Debug Prompt

"Give me new Lambda function with debug statements."

Check Connectivity Prompt

"How do I know if API Gateway is able to reach Lambda?"

Final API Setup Prompt
