Advanced Features

Streaming

stream = client.chat.completions.create(
    model="anthropic.claude-3-5-sonnet-20241022-v2:0",
    messages=[{"role": "user", "content": "Count to 10"}],
    stream=True
)

for chunk in stream:
    if chunk.choices[0].delta.content:
        print(chunk.choices[0].delta.content, end="")

Function Calling (Converse API)

tools = [
    {
        "type": "function",
        "function": {
            "name": "get_weather",
            "description": "Get current weather",
            "parameters": {
                "type": "object",
                "properties": {
                    "location": {"type": "string"}
                },
                "required": ["location"]
            }
        }
    }
]

response = client.chat.completions.create(
    model="anthropic.claude-3-5-sonnet-20241022-v2:0",
    messages=[{"role": "user", "content": "What's the weather in Tokyo?"}],
    tools=tools
)

Embeddings

response = client.embeddings.create(
    model="amazon.titan-embed-text-v2:0",
    input="AWS Bedrock provides access to foundation models"
)

embedding = response.data[0].embedding
print(f"Dimensions: {len(embedding)}")

Image Generation

response = client.images.generate(
    model="stability.sd3-large-v1:0",
    prompt="A serene mountain landscape at sunset",
    size="1024x1024"
)

image_url = response.data[0].url

Batch Inference

Create batch jobs for cost-effective inference:

# Create batch job
response = client.batches.create(
    model="anthropic.claude-3-5-sonnet-20241022-v2:0",
    input_file_id="s3://my-bucket/input.jsonl",
    output_data_config={
        "s3OutputDataConfig": {
            "s3Uri": "s3://my-bucket/output/"
        }
    }
)

batch_id = response.id

# Check status
batch = client.batches.retrieve(batch_id)
print(f"Status: {batch.status}")

Cross-Region Inference

Use inference profiles for cross-region routing:

response = client.chat.completions.create(
    model="us.anthropic.claude-3-5-sonnet-20241022-v2:0",  # Inference profile
    messages=[{"role": "user", "content": "Hello"}]
)

Multi-Region Configuration

Load balance across AWS regions:

config = {
    "strategy": {"mode": "loadbalance"},
    "targets": [
        {
            "provider": "bedrock",
            "aws_access_key_id": "AKIA***",
            "aws_secret_access_key": "***",
            "aws_region": "us-east-1",
            "weight": 0.5
        },
        {
            "provider": "bedrock",
            "aws_access_key_id": "AKIA***",
            "aws_secret_access_key": "***",
            "aws_region": "us-west-2",
            "weight": 0.5
        }
    ]
}

client = Portkey().with_options(config=config)

Fallback Configuration

Fallback from Bedrock Claude to Anthropic:

config = {
    "strategy": {"mode": "fallback"},
    "targets": [
        {
            "provider": "bedrock",
            "aws_access_key_id": "AKIA***",
            "aws_secret_access_key": "***",
            "aws_region": "us-east-1",
            "override_params": {"model": "anthropic.claude-3-5-sonnet-20241022-v2:0"}
        },
        {
            "provider": "anthropic",
            "api_key": "sk-ant-***",
            "override_params": {"model": "claude-3-5-sonnet-20241022"}
        }
    ]
}

client = Portkey().with_options(config=config)

Error Handling

from portkey_ai.exceptions import (
    RateLimitError,
    APIError,
    AuthenticationError
)

try:
    response = client.chat.completions.create(
        model="anthropic.claude-3-5-sonnet-20241022-v2:0",
        messages=[{"role": "user", "content": "Hello"}]
    )
except AuthenticationError as e:
    print(f"AWS credentials error: {e}")
except RateLimitError as e:
    print(f"Rate limit or quota exceeded: {e}")
except APIError as e:
    print(f"Bedrock API error: {e}")

Best Practices

Use IAM roles - More secure than access keys
Enable VPC endpoints - Private connectivity
Request model access - Models require explicit access approval
Use inference profiles - Better availability and routing
Monitor with CloudWatch - Track usage and costs
Set up guardrails - Content filtering and safety
Use batch inference - Cost-effective for large workloads
Implement retry logic - Handle throttling gracefully

Model Access

Before using models, request access in the AWS Console:

Go to AWS Bedrock Console
Navigate to Model access
Click Manage model access
Select models and request access
Wait for approval (usually instant)

Models are region-specific. Request access in each region you plan to use.

Regional Availability

Bedrock is available in multiple AWS regions:

US: us-east-1, us-west-2
Europe: eu-central-1, eu-west-1, eu-west-3
Asia Pacific: ap-southeast-1, ap-northeast-1, ap-south-1

Model availability varies by region. Check the AWS Bedrock documentation for details.

Pricing

Bedrock pricing includes:

On-demand: Pay per request/token
Provisioned throughput: Reserved capacity
Model customization: Additional costs for fine-tuning
