You may also entry the mannequin programmatically utilizing the Anthropic Messages API to name the bedrock-runtime by way of Anthropic SDK or bedrock-mantle endpoints, or hold utilizing the Invoke and Converse API on bedrock-runtime by way of the AWS Command Line Interface (AWS CLI) and AWS SDK.

Stipulations

Lively AWS account with Amazon Bedrock entry
AWS CLI put in and configured
Python 3.8+
Boto3 put in: pip set up boto3
Anthropic SDK put in: pip set up anthropic[bedrock]
IAM permissions: bedrock:InvokeModel, bedrock:InvokeModelWithResponseStream, and bedrock:CreateInference

Right here’s a fast instance utilizing the AWS SDK for Python (Boto3):

import boto3
import json

# Create a Bedrock Runtime shopper
bedrock_runtime = boto3.shopper(
    service_name="bedrock-runtime",
    region_name="us-east-1"
)

# Invoke Claude Sonnet 5
response = bedrock_runtime.invoke_model(
    modelId="us.anthropic.claude-sonnet-5",
    contentType="software/json",
    settle for="software/json",
    physique=json.dumps({
        "anthropic_version": "bedrock-2023-05-31",
        "max_tokens": 4096,
        "messages": [
            {
                "role": "user",
                "content": "Design a distributed architecture on AWS in Python that should support 100k requests per second across multiple geographic regions."
            }
        ]
    })
)

outcome = json.masses(response["body"].learn())
print(outcome["content"][0]["text"])

You may also use Claude Sonnet 5 with the Amazon Bedrock Converse API for a unified multi-model expertise:

import boto3

bedrock_runtime = boto3.shopper("bedrock-runtime", region_name="us-east-1")

response = bedrock_runtime.converse(
    modelId="us.anthropic.claude-sonnet-5",
    messages=[
        {
            "role": "user",
            "content": [
                {
                    "text": "Design a distributed architecture on AWS in Python that should support 100k requests per second across multiple geographic regions."
                }
            ]
        }
    ],
    inferenceConfig={
        "maxTokens": 4096
    }
)

print(response["output"]["message"]["content"][0]["text"])

You may also use Claude Sonnet 5 with the Anthropic Messages API utilizing the anthropic[bedrock] SDK bundle for a streamlined expertise:

from anthropic import AnthropicBedrockMantle

# Initialize the Bedrock Mantle shopper (makes use of SigV4 auth mechanically)
mantle_client = AnthropicBedrockMantle(aws_region="us-east-1")

# Create a message utilizing the Messages API
message = mantle_client.messages.create(
    mannequin="anthropic.claude-sonnet-5",
    max_tokens=4096,
    messages=[
        {"role": "user", "content": "Design a distributed architecture on AWS in Python that should support 100k requests per second across multiple geographic regions"}
    ]
)

print(message.content material[0].textual content)
