Qwen3 Max Thinking Is Now Available in Puter.js

Puter.js now supports Qwen3 Max Thinking, Alibaba Cloud's flagship proprietary reasoning model that competes with GPT-5.2 and Gemini 3 Pro.

What is Qwen3 Max Thinking?

Qwen3 Max Thinking is Alibaba Cloud's most powerful reasoning model, featuring test-time scaling and adaptive tool-use capabilities that allow it to reason iteratively and autonomously. Key features include:

• 256K Context Window: Handles massive inputs for complex, long-context tasks
• Test-Time Scaling: Dynamically allocates more compute to harder problems for better accuracy
• Competitive Benchmarks: Scores competitively against GPT-5.2 and Gemini 3 Pro on Humanity's Last Exam and HMMT, with perfect scores on AIME 2025

Examples

Complex reasoning

  { model: 'qwen/qwen3-max-thinking' }
);

Math problem solving

puter.ai.chat("Solve: Find all functions f: R -> R such that f(x + y) = f(x) + f(y) for all real x, y",
  { model: 'qwen/qwen3-max-thinking' }
);

Code generation with reasoning

puter.ai.chat("Design and implement a lock-free concurrent queue in C++ with memory ordering guarantees",
  { model: 'qwen/qwen3-max-thinking' }
);

Multi-step analysis

puter.ai.chat("Analyze the time and space complexity of Dijkstra's algorithm with a Fibonacci heap vs a binary heap, and explain when each is preferable",
  { model: 'qwen/qwen3-max-thinking' }
);
