Introduction to Amazon Nova Micro

Amazon Nova Micro is a lightweight, powerful, and efficient large language model (LLM) offered through Amazon Bedrock. It specializes in generating natural language responses, summaries, and contextually relevant content in real-time, enabling a wide range of applications like conversational AI, content generation, and text-based automation.

What Does Amazon Nova Micro Generate?

At its core, Amazon Nova Micro generates human-like text based on the input provided. This text can vary widely depending on the use case and input configuration. Here’s what it can generate:

1. Conversational Responses:
   • Engages in natural, human-like dialogue.
   • Useful for building AI-powered chatbots and virtual assistants.
2. Text Summaries:
   • Condenses long pieces of text or documents into concise summaries.
   • Ideal for report generation and quick content consumption.
3. Creative Content:
   • Generates ideas for blog posts, social media captions, or storylines.
   • Helps writers and marketers brainstorm or produce engaging material.
4. Code Suggestions and Explanations:
   • Generates code snippets or provides explanations for programming logic.
   • Supports developers in learning or debugging tasks.
5. Custom Knowledge-Based Answers:
   • Provides detailed responses to user queries based on training data.
   • Can explain complex concepts or offer insights.
6. Data-Driven Outputs:
   • Processes and transforms structured data into meaningful, readable text.
   • Examples: Translating database entries into summaries or generating reports.

How It Works

Amazon Nova Micro uses a pre-trained deep learning model optimized for generating and understanding human language. It works as follows:

1. Input:
   • A user provides text, such as a question, a partial sentence, or a specific request.
2. Processing:
   • The model processes the input to understand the context and intent.

1. Output:
   • Nova Micro generates the desired text output, whether it’s a simple answer, a long-form response, or creative content.

 

Step-by-Step Implementation of Amazon Nova Micro with AWS Lambda

STEP-1:

Go to  Amazon Bedrock -> Model Access -> Request model access

Search for Nova Models

Click Next, then Submit

 

STEP-2:

Create an API Gateway and a Lambda Function.

Use the following Lambda Code written in Python

 

import boto3

import json

def lambda_handler(event, context):

    try:

        # Print the incoming event for debugging

        print(“Received event:”, json.dumps(event))

       

        # Parse input text from the API Gateway event

        body = json.loads(event.get(‘body’, ‘{}‘))

        print(“Parsed body:”, body)

       

        input_text = body.get(‘text’, ”)

        print(“Input text:”, input_text)

       

        if not input_text:

            print(“No input text provided.”)

            return {

                “statusCode”: 400,

                “body”: json.dumps({“error”: “Input text is required”})

            }

       

        # Prepare payload for Amazon Bedrock Nova

        payload = {

            “messages”: [

                {

                    “role”: “user”,

                    “content”: [{“text”: input_text}]  # Wrap content in an array of JSON objects

                }

            ],

            “inferenceConfig”: {

                “max_new_tokens”: 1000

            }

        }

       

        print(“Payload for Bedrock:”, json.dumps(payload))

       

        # Initialize Bedrock client

        client = boto3.client(“bedrock-runtime”)

        print(“Initialized Bedrock client.”)

       

        # Call Bedrock for inference

        response = client.invoke_model(

            modelId=“amazon.nova-micro-v1:0”,

            contentType=“application/json”,

            accept=“application/json”,

            body=json.dumps(payload)

        )

       

        print(“Response from Bedrock:”, response)

       

        # Parse Bedrock response

        response_body = json.loads(response[‘body’].read())

        print(“Parsed response body:”, response_body)

       

        return {

            “statusCode”: 200,

            “body”: json.dumps({“result”: response_body})

        }

    except Exception as e:

        # Print the exception for debugging

        print(“Error occurred:”, str(e))

        return {

            “statusCode”: 500,

            “body”: json.dumps({“error”: str(e)})

        }

STEP-3:

Set up your Angular frontend and use the API Gateway URL to get the result.
