Running Basic Inference

To perform inference using a chosen foundation model in AWS Bedrock, follow these steps:

Customizing Model Outputs

Fine-tune output behavior by adjusting parameters like temperature and maxTokenCount:

• Temperature: Controls randomness; lower values yield deterministic results; higher values enhance variability.
• MaxTokenCount: Sets maximum length of generated output to tailor creativity and length according to application needs.

# Sample code snippet demonstrating parameter adjustment

response = client.invoke_model(

    ModelId='TitanTextG1',

    Input={

        'prompt': 'Create a marketing copy.',

        'parameters': {

            'temperature': 0.7,

            'maxTokenCount': 150

        }

    }

)

print(response['Output'])

 

Format the Request Payload:

Define the model ID and input prompt clearly when invoking the model.

# Example payload structure

payload = {

   "ModelId": "TitanTextG1",

   "Input": {"prompt": "What are the benefits of cloud computing?"}

}

 

Initialize the Bedrock Client:

Create an AWS SDK for Python (boto3) runtime client in your preferred region.

import boto3

 

client = boto3.client('bedrock', region_name='us-west-2')

By following this structured approach with Amazon Bedrock's foundation models, you can harness their full potential for your generative AI applications efficiently and effectively.
