Today we are adding Qwen models from Alibaba in Amazon Bedrock. With this launch, Amazon Bedrock continues to expand model choice by adding access to Qwen3 open weight foundation models (FMs) in a full managed, serverless way. This release includes four models: Qwen3-Coder-480B-A35B-Instruct, Qwen3-Coder-30B-A3B-Instruct, Qwen3-235B-A22B-Instruct-2507, and Qwen3-32B (Dense). Together, these models feature both mixture-of-experts (MoE) and dense architectures, providing flexible options for different application requirements.
Amazon Bedrock provides access to industry-leading FMs through a unified API without requiring infrastructure management. You can access models from multiple model providers, integrate models into your applications, and scale usage based on workload requirements. With Amazon Bedrock, customer data is never used to train the underlying models. With the addition of Qwen3 models, Amazon Bedrock offers even more options for use cases like:
Qwen3 models in Amazon Bedrock
These four Qwen3 models are now available in Amazon Bedrock, each optimized for different performance and cost requirements:
Architectural and functional features in Qwen3
The Qwen3 models introduce several architectural and functional features:
MoE compared with dense architectures - MoE models such as Qwen3-Coder-480B-A35B, Qwen3-Coder-30B-A3B-Instruct, and Qwen3-235B-A22B-Instruct-2507, activate only part of the parameters for each request, providing high performance with efficient inference. The dense Qwen3-32B activates all parameters, offering more consistent and predictable performance.
Agentic capabilities - Qwen3 models can handle multi-step reasoning and structured planning in one model invocation. They can generate outputs that call external tools or APIs when integrated into an agent framework. The models also maintain extended context across long sessions. In addition, they support tool calling to allow standardized communication with external environments.
Hybrid thinking modes - Qwen3 introduces a hybrid approach to problem-solving, which supports two modes: thinking and non-thinking. The thinking mode applies step-by-step reasoning before delivering the final answer. This is ideal for complex problems that require deeper thought. Whereas the non-thinking mode provides fast and near-instant responses for less complex tasks where speed is more important than depth. This helps developers manage performance and cost trade-offs more effectively.
Long-context handling - The Qwen3-Coder models support extended context windows, with up to 256K tokens natively and up to 1 million tokens with extrapolation methods. This allows the model to process entire repositories, large technical documents, or long conversational histories within a single task.
When to use each model
The four Qwen3 models serve distinct use cases. Qwen3-Coder-480B-A35B-Instruct is designed for complex software engineering scenarios. It's suited for advanced code generation, long-context processing such as repository-level analysis, and integration with external tools. Qwen3-Coder-30B-A3B-Instruct is particularly effective for tasks such as code completion, refactoring, and answering programming-related queries. If you need versatile performance across multiple domains, Qwen3-235B-A22B-Instruct-2507 offers a balance, delivering strong general-purpose reasoning and instruction-following capabilities while leveraging the efficiency advantages of its MoE architecture. Qwen3-32B (Dense) is appropriate for scenarios where consistent performance, low latency, and cost optimization are important.
Getting started with Qwen models in Amazon Bedrock
To begin using Qwen models, in the Amazon Bedrock console, I choose Model Access from the Configure and learn section of the navigation pane. I then navigate to the Qwen models to request access. In the Chat/Text Playground section of the navigation pane, I can quickly test the new Qwen models with my prompts.
To integrate Qwen3 models into my applications, I can use any AWS SDKs. The AWS SDKs include access to the Amazon Bedrock InvokeModel and Converse API. I can also use these model with any agentic framework that supports Amazon Bedrock and deploy the agents using Amazon Bedrock AgentCore. For example, here's the Python code of a simple agent with tool access built using Strands Agents:
from strands import Agent from strands_tools import calculator agent = Agent( model="qwen.qwen3-coder-480b-instruct-v1:0", tools=[calculator] ) agent("Tell me the square root of 42 ^ 9") with open("function.py", 'r') as f: my_function_code = f.read() agent(f"Help me optimize this Python function for better performance:\n\n{my_function_code}")
Now available
Qwen models are available today in the following AWS Regions:
Check the full Region list for future updates. You can start testing and building immediately without infrastructure setup or capacity planning. To learn more, visit the Qwen in Amazon Bedrock product page and the Amazon Bedrock pricing page.
Try Qwen models on the Amazon Bedrock console now, and offer feedback through AWS re:Post for Amazon Bedrock or your typical AWS Support channels.
