[QWEN STUDIO](https://chat.qwen.ai) [HUGGING FACE](https://huggingface.co/Qwen/Qwen3.6-27B) [MODELSCOPE](https://modelscope.cn/models/Qwen/Qwen3.6-27B) [DISCORD](https://discord.gg/yPEP2vHTu4)

Following the launch of [Qwen3.6-Plus](https://qwen.ai/blog?id=qwen3.6) and [Qwen3.6-35B-A3B](https://qwen.ai/blog?id=qwen3.6-35b-a3b), we are excited to open-source **Qwen3.6-27B** — a dense 27-billion-parameter multimodal model at the scale the community has been asking for most. Still supporting both multimodal thinking and non-thinking modes, Qwen3.6-27B delivers flagship-level agentic coding performance, **surpassing the previous-generation open-source flagship Qwen3.5-397B-A17B** (397B total / 17B active MoE) across all major coding benchmarks. As a dense architecture, it is straightforward to deploy without MoE routing complexity, making it an ideal choice for developers who need top-tier coding capabilities at a practical, widely-deployable scale. Qwen3.6-27B is now live on Qwen Studio, available through our API, and released as open weights for the community.

- **Qwen3.6-27B** is a fully open-source dense model (27B parameters), featuring:
  - flagship-level agentic coding that surpasses Qwen3.5-397B-A17B
  - strong text and multimodal reasoning ability
- You can chat interactively on [Qwen Studio](https://chat.qwen.ai), call via API on [Alibaba Cloud Model Studio API](https://modelstudio.alibabacloud.com/) (coming soon), or download weights from [Hugging Face](https://huggingface.co/Qwen/Qwen3.6-27B) and [ModelScope](https://modelscope.cn/models/Qwen/Qwen3.6-27B).

## Performance

Below we present comprehensive evaluations of Qwen3.6-27B against both dense and MoE baselines, including our previous-generation open-source flagship Qwen3.5-397B-A17B. Qwen3.6-27B delivers remarkable improvements across agentic coding benchmarks, surpassing models with up to 15x its total parameter count.

### Language

Qwen3.6-27B achieves a breakthrough in agentic coding for dense models. With only 27B parameters, it outperforms the Qwen3.5-397B-A17B (397B total / 17B active) on every major coding benchmark — including SWE-bench Verified (77.2 vs. 76.2), SWE-bench Pro (53.5 vs. 50.9), Terminal-Bench 2.0 (59.3 vs. 52.5), and SkillsBench (48.2 vs. 30.0). It also surpasses all peer-scale dense models by a wide margin. On reasoning tasks, Qwen3.6-27B achieves 87.8 on GPQA Diamond, competitive with models several times its size.

### Vision Language

Qwen3.6-27B is natively multimodal, supporting both vision-language thinking and non-thinking modes in a single unified checkpoint — the same as Qwen3.6-35B-A3B. It handles images and video alongside text, enabling multimodal reasoning, document understanding, and visual question answering.

## Build with Qwen3.6-27B

Qwen3.6-27B is coming soon to Alibaba Cloud Model Studio. Please stand by until we are fully ready.

Qwen3.6-27B is available as open weights on [Hugging Face](https://huggingface.co/Qwen/Qwen3.6-27B) and [ModelScope](https://modelscope.cn/models/Qwen/Qwen3.6-27B) for self-hosting, and through the [Alibaba Cloud Model Studio](https://modelstudio.alibabacloud.com/) API. You can also try it instantly on [Qwen Studio](https://chat.qwen.ai).

The model can be seamlessly integrated with popular third-party coding assistants, including OpenClaw, Claude Code, and Qwen Code, to streamline development workflows and enable efficient, context-aware coding experiences.

### API Usage

This release supports the `preserve_thinking` feature: preserving thinking content from all preceding turns in messages, which is **recommended for agentic tasks**.

#### Alibaba Cloud Model Studio

Alibaba Cloud Model Studio supports industry-standard protocols, including chat completions and responses APIs compatible with OpenAI’s specification, as well as an API interface compatible with Anthropic.

Example code for chat completions API is provided below:

### Coding & Agents

Qwen3.6-27B features excellent agentic coding capabilities and can be seamlessly integrated into popular third-party coding assistants, including OpenClaw, Claude Code, and Qwen Code.

#### OpenClaw

Qwen3.6-27B is compatible with [OpenClaw](https://openclaw.ai) (formerly Moltbot / Clawdbot), a self-hosted open-source AI coding agent. Connect it to [Model Studio](https://www.alibabacloud.com/help/en/model-studio/openclaw) to get a full agentic coding experience in the terminal. Get started with the following script:

```bash
# Node.js 22+
curl -fsSL https://molt.bot/install.sh | bash   # macOS / Linux

# Set your API key
export DASHSCOPE_API_KEY=<your_api_key>

# Launch OpenClaw
openclaw dashboard # web browser
# openclaw tui # Open a new terminal and start the TUI
```

On first use, edit `~/.openclaw/openclaw.json` to point OpenClaw at Model Studio. Find or create the following fields and merge them — **do not overwrite the entire file** to preserve your existing settings:

```json
{
  "models": {
    "mode": "merge",
    "providers": {
      "modelstudio": {
        "baseUrl": "https://dashscope-intl.aliyuncs.com/compatible-mode/v1",
        "apiKey": "DASHSCOPE_API_KEY",
        "api": "openai-completions",
        "models": [
          {
            "id": "qwen3.6-27b",
            "name": "qwen3.6-27b",
            "reasoning": true,
            "input": ["text", "image"],
            "contextWindow": 131072,
            "maxTokens": 16384
          }
        ]
      }
    }
  },
  "agents": {
    "defaults": {
      "model": {
        "primary": "modelstudio/qwen3.6-27b"
      },
      "models": {
        "modelstudio/qwen3.6-27b": {}
      }
    }
  }
}
```

#### Qwen Code

Qwen3.6-27B is compatible with [Qwen Code](https://qwen.ai/qwencode), an open-source AI agent designed for the terminal and deeply optimized for the Qwen Series. Get started with the following script:

```bash
# Node.js 20+
npm install -g @qwen-code/qwen-code@latest

# Start Qwen Code (interactive)
qwen

# Then, in the session:
/help
/auth
```

On first use, you’ll be prompted to sign in. You can run `/auth` anytime to switch authentication methods.

#### Claude Code

Qwen APIs also support the Anthropic API protocol, meaning you can use it with tools like **Claude Code** for elevated coding experience:

```bash
# Install Claude Code
npm install -g @anthropic-ai/claude-code

# Configure environment
export ANTHROPIC_MODEL="qwen3.6-27b"
export ANTHROPIC_SMALL_FAST_MODEL="qwen3.6-27b"
export ANTHROPIC_BASE_URL=https://dashscope-intl.aliyuncs.com/apps/anthropic
export ANTHROPIC_AUTH_TOKEN=<your_api_key>

# Launch the CLI
claude
```

## Summary

Qwen3.6-27B demonstrates that a well-trained dense model can surpass much larger predecessors on the tasks that matter most for developers. At 27 billion parameters — the most widely deployed open-source scale — it outperforms the 397B-parameter Qwen3.5-397B-A17B on every major agentic coding benchmark, while remaining straightforward to deploy and serve. With Qwen3.6-27B joining the roster, the Qwen3.6 open-source family now offers a comprehensive range of models, underscoring a generation where agentic coding achieved breakthroughs across every scale — from the 3B-active Qwen3.6-35B-A3B to the API-accessible Qwen3.6-Plus and Qwen3.6-Max-Preview. We are grateful for the community’s feedback and look forward to seeing what you build with these models. Stay tuned for more from the Qwen team!
