Qwen3 family of reasoning models now available in Amazon Bedrock Marketplace and Amazon SageMaker JumpStart

Today, we are excited to announce that Qwen3, the latest generation of large language models (LLMs) in the Qwen family, is available through Amazon Bedrock Marketplace and Amazon SageMaker JumpStart. With this launch, you can deploy the Qwen3 models—available in 0.6B, 4B, 8B, and 32B parameter sizes—to build, experiment, and responsibly scale your generative AI applications on AWS.

In this post, we demonstrate how to get started with Qwen3 on Amazon Bedrock Marketplace and SageMaker JumpStart. You can follow similar steps to deploy the distilled versions of the models as well.

Solution overview

Qwen3 is the latest generation of LLMs in the Qwen series, offering a comprehensive suite of dense and mixture-of-experts (MoE) models. Qwen3 delivers groundbreaking advancements in reasoning, instruction-following, agent capabilities, and multilingual support, with the following key features:

• Unique support of seamless switching between thinking mode and non-thinking mode within a single model, providing optimal performance across various scenarios.
• Significantly enhanced in its reasoning capabilities, surpassing previous QwQ (in thinking mode) and Qwen2.5 instruct models (in non-thinking mode) on mathematics, code generation, and commonsense logical reasoning.
• Good human preference alignment, excelling in creative writing, role-playing, multi-turn dialogues, and instruction following, to deliver a more natural, engaging, and immersive conversational experience.
• Expertise in agent capabilities, enabling precise integration with external tools in both thinking and unthinking modes and achieving leading performance among open source models in complex agent-based tasks.
• Support for over 100 languages and dialects with strong capabilities for multilingual instruction following and translation.

Prerequisites

To deploy Qwen3 models, make sure you have access to the recommended instance types based on the model size. You can find these instance recommendations on Amazon Bedrock Marketplace or the SageMaker JumpStart console. To verify you have the necessary resources, complete the following steps:

1. Open the Service Quotas console.
2. Under AWS Services, select Amazon SageMaker.
3. Check that you have sufficient quota for the required instance type for endpoint deployment.
4. Make sure at least one of these instance types is available in your target AWS Region.

If needed, request a quota increase and contact your AWS account team for support.

Deploy Qwen3 in Amazon Bedrock Marketplace

Amazon Bedrock Marketplace gives you access to over 100 popular, emerging, and specialized foundation models (FMs) through Amazon Bedrock. To access Qwen3 in Amazon Bedrock, complete the following steps:

1. On the Amazon Bedrock console, in the navigation pane under Foundation models, choose Model catalog.
2. Filter for Hugging Face as a provider and choose a Qwen3 model. For this example, we use the Qwen3-32B model.

The model detail page provides essential information about the model’s capabilities, pricing structure, and implementation guidelines. You can find detailed usage instructions, including sample API calls and code snippets for integration.

The page also includes deployment options and licensing information to help you get started with Qwen3-32B in your applications.

1. To begin using Qwen3-32B, choose Deploy.

You will be prompted to configure the deployment details for Qwen3-32B. The model ID will be pre-populated.

2. For Endpoint name, enter an endpoint name (between 1–50 alphanumeric characters).
3. For Number of instances, enter a number of instances (between 1–100).
4. For Instance type, choose your instance type. For optimal performance with Qwen3-32B, a GPU-based instance type like ml.g5-12xlarge is recommended.
5. To deploy the model, choose Deploy.

When the deployment is complete, you can test Qwen3-32B’s capabilities directly in the Amazon Bedrock playground.

6. Choose Open in playground to access an interactive interface where you can experiment with different prompts and adjust model parameters like temperature and maximum length.

This is an excellent way to explore the model’s reasoning and text generation abilities before integrating it into your applications. The playground provides immediate feedback, helping you understand how the model responds to various inputs and letting you fine-tune your prompts for optimal results.You can quickly test the model in the playground through the UI. However, to invoke the deployed model programmatically with any Amazon Bedrock APIs, you must have the endpoint Amazon Resource Name (ARN).

Enable reasoning and non-reasoning responses with Converse API

The following code shows how to turn reasoning on and off with Qwen3 models using the Converse API, depending on your use case. By default, reasoning is left on for Qwen3 models, but you can streamline interactions by using the /no_think command within your prompt. When you add this to the end of your query, reasoning is turned off and the models will provide just the direct answer. This is particularly useful when you need quick information without explanations, are familiar with the topic, or want to maintain a faster conversational flow. At the time of writing, the Converse API doesn’t support tool use for Qwen3 models. Refer to the Invoke_Model API example later in this post to learn how to use reasoning and tools in the same completion.

import boto3
from botocore.exceptions import ClientError

# Create a Bedrock Runtime client in the AWS Region you want to use.
client = boto3.client("bedrock-runtime", region_name="us-west-2")

# Configuration
model_id = ""  # Replace with Bedrock Marketplace endpoint arn

# Start a conversation with the user message.
user_message = "hello, what is 1+1 /no_think" #remove /no_think to leave default reasoning on
conversation = [
    {
        "role": "user",
        "content": [{"text": user_message}],
    }
]

try:
    # Send the message to the model, using a basic inference configuration.
    response = client.converse(
        modelId=model_id,
        messages=conversation,
        inferenceConfig={"maxTokens": 512, "temperature": 0.5, "topP": 0.9},
    )

    # Extract and print the response text.
    #response_text = response["output"]["message"]["content"][0]["text"]
    #reasoning_content = response ["output"]["message"]["reasoning_content"][0]["text"]
    #print(response_text, reasoning_content)
    print(response)
    
except (ClientError, Exception) as e:
    print(f"ERROR: Can't invoke '{model_id}'. Reason: {e}")
    exit(1)

The following is a response using the Converse API, without default thinking:

{'ResponseMetadata': {'RequestId': 'f7f3953a-5747-4866-9075-fd4bd1cf49c4', 'HTTPStatusCode': 200, 'HTTPHeaders': {'date': 'Tue, 17 Jun 2025 18:34:47 GMT', 'content-type': 'application/json', 'content-length': '282', 'connection': 'keep-alive', 'x-amzn-requestid': 'f7f3953a-5747-4866-9075-fd4bd1cf49c4'}, 'RetryAttempts': 0}, 'output': {'message': {'role': 'assistant', 'content': [{'text': 'nnHello! The result of 1 + 1 is **2**. 😊'}, {'reasoningContent': {'reasoningText': {'text': 'nn'}}}]}}, 'stopReason': 'end_turn', 'usage': {'inputTokens': 20, 'outputTokens': 22, 'totalTokens': 42}, 'metrics': {'latencyMs': 1125}}

The following is an example with default thinking on; the <think> tokens are automatically parsed into the reasoningContent field for the Converse API:

{'ResponseMetadata': {'RequestId': 'b6d2ebbe-89da-4edc-9a3a-7cb3e7ecf066', 'HTTPStatusCode': 200, 'HTTPHeaders': {'date': 'Tue, 17 Jun 2025 18:32:28 GMT', 'content-type': 'application/json', 'content-length': '1019', 'connection': 'keep-alive', 'x-amzn-requestid': 'b6d2ebbe-89da-4edc-9a3a-7cb3e7ecf066'}, 'RetryAttempts': 0}, 'output': {'message': {'role': 'assistant', 'content': [{'text': 'nnHello! The sum of 1 + 1 is **2**. Let me know if you have any other questions or need further clarification! 😊'}, {'reasoningContent': {'reasoningText': {'text': 'nOkay, the user asked "hello, what is 1+1". Let me start by acknowledging their greeting. They might just be testing the water or actually need help with a basic math problem. Since it's 1+1, it's a very simple question, but I should make sure to answer clearly. Maybe they're a child learning math for the first time, or someone who's not confident in their math skills. I should provide the answer in a friendly and encouraging way. Let me confirm that 1+1 equals 2, and maybe add a brief explanation to reinforce their understanding. I can also offer further assistance in case they have more questions. Keeping it conversational and approachable is key here.n'}}}]}}, 'stopReason': 'end_turn', 'usage': {'inputTokens': 16, 'outputTokens': 182, 'totalTokens': 198}, 'metrics': {'latencyMs': 7805}}

Perform reasoning and function calls in the same completion using the Invoke_Model API

With Qwen3, you can stream an explicit trace and the exact JSON tool call in the same completion. Up until now, reasoning models have forced the choice to either show the chain of thought or call tools deterministically. The following code shows an example:

messages = json.dumps( {
    "messages": [
        {
            "role": "user",
            "content": "Hi! How are you doing today?"
        }, 
        {
            "role": "assistant",
            "content": "I'm doing well! How can I help you?"
        }, 
        {
            "role": "user",
            "content": "Can you tell me what the temperate will be in Dallas, in fahrenheit?"
        }
    ],
    "tools": [{
        "type": "function",

                    },
                    "state": {
                        "type":
                            "string",
                        "description":
                            "the two-letter abbreviation for the state that the city is in, e.g. 'CA' which would mean 'California'"
                    },
                    "unit": {
                        "type": "string",
                        "description":

                    }
                },
                "required": ["city", "state", "unit"]
            }
        }
    }],
    "tool_choice": "auto"
})

response = client.invoke_model(
    modelId=model_id, 
    body=body
)
print(response)
model_output = json.loads(response['body'].read())
print(json.dumps(model_output, indent=2))

Deploy Qwen3-32B with SageMaker JumpStart

SageMaker JumpStart is a machine learning (ML) hub with FMs, built-in algorithms, and prebuilt ML solutions that you can deploy with just a few clicks. With SageMaker JumpStart, you can customize pre-trained models to your use case, with your data, and deploy them into production using either the UI or SDK.Deploying the Qwen3-32B model through SageMaker JumpStart offers two convenient approaches: using the intuitive SageMaker JumpStart UI or implementing programmatically through the SageMaker Python SDK. Let’s explore both methods to help you choose the approach that best suits your needs.

Deploy Qwen3-32B through SageMaker JumpStart UI

Complete the following steps to deploy Qwen3-32B using SageMaker JumpStart:

1. On the SageMaker console, choose Studio in the navigation pane.
2. First-time users will be prompted to create a domain.
3. On the SageMaker Studio console, choose JumpStart in the navigation pane.

The model browser displays available models, with details like the provider name and model capabilities.

4. Search for Qwen3 to view the Qwen3-32B model card.

Each model card shows key information, including:

• Model name
• Provider name
• Task category (for example, Text Generation)
• Bedrock Ready badge (if applicable), indicating that this model can be registered with Amazon Bedrock, so you can use Amazon Bedrock APIs to invoke the model

5. Choose the model card to view the model details page.

The model details page includes the following information:

• The model name and provider information
• A Deploy button to deploy the model
• About and Notebooks tabs with detailed information

The About tab includes important details, such as:

• Model description
• License information
• Technical specifications
• Usage guidelines

Before you deploy the model, it’s recommended to review the model details and license terms to confirm compatibility with your use case.

6. Choose Deploy to proceed with deployment.
7. For Endpoint name, use the automatically generated name or create a custom one.
8. For Instance type¸ choose an instance type (default: ml.g6-12xlarge).
9. For Initial instance count, enter the number of instances (default: 1).

Selecting appropriate instance types and counts is crucial for cost and performance optimization. Monitor your deployment to adjust these settings as needed. Under Inference type, Real-time inference is selected by default. This is optimized for sustained traffic and low latency.

10. Review all configurations for accuracy. For this model, we strongly recommend adhering to SageMaker JumpStart default settings and making sure that network isolation remains in place.
11. Choose Deploy to deploy the model.

The deployment process can take several minutes to complete.

When deployment is complete, your endpoint status will change to InService. At this point, the model is ready to accept inference requests through the endpoint. You can monitor the deployment progress on the SageMaker console Endpoints page, which will display relevant metrics and status information. When the deployment is complete, you can invoke the model using a SageMaker runtime client and integrate it with your applications.

Deploy Qwen3-32B using the SageMaker Python SDK

To get started with Qwen3-32B using the SageMaker Python SDK, you must install the SageMaker Python SDK and make sure you have the necessary AWS permissions and environment set up. The following is a step-by-step code example that demonstrates how to deploy and use Qwen3-32B for inference programmatically:

!pip install --force-reinstall --no-cache-dir sagemaker==2.235.2

from sagemaker.serve.builder.model_builder import ModelBuilder 
from sagemaker.serve.builder.schema_builder import SchemaBuilder 
from sagemaker.jumpstart.model import ModelAccessConfig 
from sagemaker.session import Session 
import logging 

sagemaker_session = Session()
artifacts_bucket_name = sagemaker_session.default_bucket() 
execution_role_arn = sagemaker_session.get_caller_identity_arn()

# Changed to Qwen32B model
js_model_id = "huggingface-reasoning-qwen3-32b"
gpu_instance_type = "ml.g5.12xlarge"

response = "Hello, I'm a language model, and I'm here to help you with your English."

sample_input = {
    "inputs": "Hello, I'm a language model,",
    "parameters": {
        "max_new_tokens": 128, 
        "top_p": 0.9, 
        "temperature": 0.6
    }
}

sample_output = [{"generated_text": response}]

schema_builder = SchemaBuilder(sample_input, sample_output)

model_builder = ModelBuilder( 
    model=js_model_id, 
    schema_builder=schema_builder, 
    sagemaker_session=sagemaker_session, 
    role_arn=execution_role_arn, 
    log_level=logging.ERROR 
) 

model = model_builder.build() 

predictor = model.deploy(
    model_access_configs={js_model_id: ModelAccessConfig(accept_eula=True)}, 
    accept_eula=True
) 

predictor.predict(sample_input)

You can run additional requests against the predictor:

new_input = {
"inputs": "What is Amazon doing in Generative AI?",
"parameters": {"max_new_tokens": 64, "top_p": 0.8, "temperature": 0.7},
}

prediction = predictor.predict(new_input)
print(prediction)

The following are some error handling and best practices to enhance deployment code:

# Enhanced deployment code with error handling
import backoff
import botocore
import logging

logging.basicConfig(level=logging.INFO)
logger = logging.getLogger(__name__)

@backoff.on_exception(backoff.expo, 
                     (botocore.exceptions.ClientError,),
                     max_tries=3)
def deploy_model_with_retries(model_builder, model_id):
    try:
        model = model_builder.build()
        predictor = model.deploy(
            model_access_configs={model_id:ModelAccessConfig(accept_eula=True)},
            accept_eula=True
        )
        return predictor
    except Exception as e:
        logger.error(f"Deployment failed: {str(e)}")
        raise

def safe_predict(predictor, input_data):
    try:
        return predictor.predict(input_data)
    except Exception as e:
        logger.error(f"Prediction failed: {str(e)}")
        return None

Clean up

To avoid unwanted charges, complete the steps in this section to clean up your resources.

Delete the Amazon Bedrock Marketplace deployment

If you deployed the model using Amazon Bedrock Marketplace, complete the following steps:

1. On the Amazon Bedrock console, under Foundation models in the navigation pane, choose Marketplace deployments.
2. In the Managed deployments section, locate the endpoint you want to delete.
3. Select the endpoint, and on the Actions menu, choose Delete.
4. Verify the endpoint details to make sure you’re deleting the correct deployment:
   1. Endpoint name
   2. Model name
   3. Endpoint status
5. Choose Delete to delete the endpoint.
6. In the deletion confirmation dialog, review the warning message, enter confirm, and choose Delete to permanently remove the endpoint.

Delete the SageMaker JumpStart predictor

The SageMaker JumpStart model you deployed will incur costs if you leave it running. Use the following code to delete the endpoint if you want to stop incurring charges. For more details, see Delete Endpoints and Resources.

predictor.delete_model()
