Quickstart - Amazon Bedrock

Quickstart

In this section, we will show you how to get started with Amazon Bedrock within a few minutes. We will use the OpenAI-compatible APIs: Responses API and Chat Completions API, and the Invoke and Converse API to show you how run an inference request. See Build for list of complete APIs.

Step 1 - AWS Account: If you have an AWS account already, skip this step and go to step 2. If you are new to AWS, sign up for an AWS account and follow instructions.

Step 2 - API key: Once you have an AWS account, you can create a long-term API key to authenticate your requests to Amazon Bedrock. To do that, go to the Amazon Bedrock service in AWS Console and generate a long term key. For more information, see the API keys section in the Build chapter.

Step 3 - Get the SDK: To use this getting started guide, you must have Python already installed. Then install the relevant software depending on the APIs you are using.

Responses/Chat Completions API
pip install boto3 openai
Invoke/Converse API
pip install boto3

Step 4 - Set environment variables: Configure your environment to use the API key for authentication.

Responses/Chat Completions API
OPENAI_API_KEY="<provide your long term key>" OPENAI_BASE_URL="https://bedrock-mantle.<your-region>.api.aws/v1"
Invoke/Converse API
AWS_BEARER_TOKEN_BEDROCK="<provide your long term key>"

Step 5 - Run your first inference request: Amazon Bedrock supports 100+ foundation models. Choose a model, and then use the following Python code to run your first inference request. Save the file as bedrock-first-request.py

Responses API
from openai import OpenAI client = OpenAI() response = client.responses.create( model="openai.gpt-oss-120b", input="Can you explain the features of Amazon Bedrock?" ) print(response)
Chat Completions API
from openai import OpenAI client = OpenAI() response = client.chat.completions.create( model="openai.gpt-oss-120b", messages=[{"role": "user", "content": "Can you explain the features of Amazon Bedrock?"}] ) print(response)
Invoke API
import json import boto3 client = boto3.client('bedrock-runtime', region_name='us-east-1') response = client.invoke_model( modelId='anthropic.claude-opus-4-6-v1', body=json.dumps({ 'anthropic_version': 'bedrock-2023-05-31', 'messages': [{ 'role': 'user', 'content': 'Can you explain the features of Amazon Bedrock?'}], 'max_tokens': 1024 }) ) print(json.loads(response['body'].read()))
Converse API
import boto3 client = boto3.client('bedrock-runtime', region_name='us-east-1') response = client.converse( modelId='anthropic.claude-opus-4-6-v1', messages=[ { 'role': 'user', 'content': [{'text': 'Can you explain the features of Amazon Bedrock?'}] } ] ) print(response)

Execute the code with Python by using the command:

python3 bedrock-first-request.py

You should see the output of your inference request.
