AWS Bedrock

Anthropic, Amazon Titan, A121 LLMs are Supported on Bedrock

LiteLLM requires boto3 to be installed on your system for Bedrock requests

pip install boto3>=1.28.57

OpenAI Proxy Usage

Here's how to call Anthropic with the LiteLLM Proxy Server

1. Save key in your environment

export AWS_ACCESS_KEY_ID=""
export AWS_SECRET_ACCESS_KEY=""
export AWS_REGION_NAME=""

2. Start the proxy

CLI
config.yaml

$ litellm --model anthropic.claude-3-sonnet-20240229-v1:0

# Server running on http://0.0.0.0:4000

model_list:
  - model_name: bedrock-claude-v1
    litellm_params:
      model: bedrock/anthropic.claude-instant-v1

3. Test it

Usage - Function Calling

info

Claude returns it's output as an XML Tree. Here is how we translate it.

You can see the raw response via response._hidden_params["original_response"].

Claude hallucinates, e.g. returning the list param value as <value>\n<item>apple</item>\n<item>banana</item>\n</value> or <value>\n<list>\n<item>apple</item>\n<item>banana</item>\n</list>\n</value>.

Usage - "Assistant Pre-fill"

If you're using Anthropic's Claude with Bedrock, you can "put words in Claude's mouth" by including an assistant role message as the last item in the messages array.

[!IMPORTANT] The returned completion will not include your "pre-fill" text, since it is part of the prompt itself. Make sure to prefix Claude's completion with your pre-fill.

import os
from litellm import completion

os.environ["AWS_ACCESS_KEY_ID"] = ""
os.environ["AWS_SECRET_ACCESS_KEY"] = ""
os.environ["AWS_REGION_NAME"] = ""

messages = [
    {"role": "user", "content": "How do you say 'Hello' in German? Return your answer as a JSON object, like this:\n\n{ \"Hello\": \"Hallo\" }"},
    {"role": "assistant", "content": "{"},
]
response = completion(model="bedrock/anthropic.claude-v2", messages=messages)

Example prompt sent to Claude

Human: How do you say 'Hello' in German? Return your answer as a JSON object, like this:

{ "Hello": "Hallo" }

Assistant: {

Usage - "System" messages

If you're using Anthropic's Claude 2.1 with Bedrock, system role messages are properly formatted for you.

Boto3 - Authentication

Passing credentials as parameters - Completion()

Pass AWS credentials as parameters to litellm.completion

import os
from litellm import completion

response = completion(
            model="bedrock/anthropic.claude-instant-v1",
            messages=[{ "content": "Hello, how are you?","role": "user"}],
            aws_access_key_id="",
            aws_secret_access_key="",
            aws_region_name="",
)

Passing an external BedrockRuntime.Client as a parameter - Completion()

Pass an external BedrockRuntime.Client object as a parameter to litellm.completion. Useful when using an AWS credentials profile, SSO session, assumed role session, or if environment variables are not available for auth.

Create a client from session credentials:

import boto3
from litellm import completion

bedrock = boto3.client(
            service_name="bedrock-runtime",
            region_name="us-east-1",
            aws_access_key_id="",
            aws_secret_access_key="",
            aws_session_token="",
)

response = completion(
            model="bedrock/anthropic.claude-instant-v1",
            messages=[{ "content": "Hello, how are you?","role": "user"}],
            aws_bedrock_client=bedrock,
)

Create a client from AWS profile in ~/.aws/config:

import boto3
from litellm import completion

dev_session = boto3.Session(profile_name="dev-profile")
bedrock = dev_session.client(
            service_name="bedrock-runtime",
            region_name="us-east-1",
)

response = completion(
            model="bedrock/anthropic.claude-instant-v1",
            messages=[{ "content": "Hello, how are you?","role": "user"}],
            aws_bedrock_client=bedrock,
)

Set AWS_PROFILE environment variable
Make bedrock completion call

import os
from litellm import completion

response = completion(
            model="bedrock/anthropic.claude-instant-v1",
            messages=[{ "content": "Hello, how are you?","role": "user"}]
)

or pass aws_profile_name:

import os
from litellm import completion

response = completion(
            model="bedrock/anthropic.claude-instant-v1",
            messages=[{ "content": "Hello, how are you?","role": "user"}],
            aws_profile_name="dev-profile",
)

STS based Auth

Set aws_role_name and aws_session_name in completion() / embedding() function

Make the bedrock completion call

from litellm import completion

response = completion(
            model="bedrock/anthropic.claude-instant-v1",
            messages=messages,
            max_tokens=10,
            temperature=0.1,
            aws_role_name=aws_role_name,
            aws_session_name="my-test-session",
        )

If you also need to dynamically set the aws user accessing the role, add the additional args in the completion()/embedding() function

from litellm import completion

response = completion(
            model="bedrock/anthropic.claude-instant-v1",
            messages=messages,
            max_tokens=10,
            temperature=0.1,
            aws_region_name=aws_region_name,
            aws_access_key_id=aws_access_key_id,
            aws_secret_access_key=aws_secret_access_key,
            aws_role_name=aws_role_name,
            aws_session_name="my-test-session",
        )

Provisioned throughput models

To use provisioned throughput Bedrock models pass

model=bedrock/<base-model>, example model=bedrock/anthropic.claude-v2. Set model to any of the Supported AWS models
model_id=provisioned-model-arn

Completion

import litellm
response = litellm.completion(
    model="bedrock/anthropic.claude-instant-v1",
    model_id="provisioned-model-arn",
    messages=[{"content": "Hello, how are you?", "role": "user"}]
)

Embedding

import litellm
response = litellm.embedding(
    model="bedrock/amazon.titan-embed-text-v1",
    model_id="provisioned-model-arn",
    input=["hi"],
)
