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= # 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-flash", "name": "qwen3.6-flash", "reasoning": true, "input": ["text", "image"], "contextWindow": 131072, "maxTokens": 16384 } ] } } }, "agents": { "defaults": { "model": { "primary": "modelstudio/qwen3.6-flash" }, "models": { "modelstudio/qwen3.6-flash": {} } } } } ``` #### Qwen Code Qwen3.6-35B-A3B 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-flash" export ANTHROPIC_SMALL_FAST_MODEL="qwen3.6-flash" export ANTHROPIC_BASE_URL=https://dashscope-intl.aliyuncs.com/apps/anthropic export ANTHROPIC_AUTH_TOKEN= # Launch the CLI claude ``` ## Summary Qwen3.6-35B-A3B demonstrates that sparse MoE models can achieve remarkable agentic coding and reasoning capability. With only 3B active parameters, it delivers performance that rivals dense models several times its active size, while also excelling across multimodal benchmarks. As a fully open-source checkpoint, it sets a new standard for what’s possible at its scale. Looking ahead, we will continue to expand the Qwen3.6 open-source family and push the boundaries of what efficient, open models can accomplish. We are grateful for the community’s feedback and look forward to seeing what you build with Qwen3.6-35B-A3B. Also, Qwen3.6 open-source family keeps expanding, stay tuned for our future releases! ## Citation Feel free to cite the following article if you find Qwen3.6-35B-A3B helpful: ```bibtex @misc{qwen36_35b_a3b, title = {{Qwen3.6-35B-A3B}: Agentic Coding Power, Now Open to All}, url = {https://qwen.ai/blog?id=qwen3.6-35b-a3b}, author = {{Qwen Team}}, month = {April}, year = {2026} } ```
