- A promotional image for Qwen 4 Max, reportedly leaked by an Alibaba partner, revealed features such as a 1 million token context window, image support, tool-calling capabilities, and free input/output tokens. The image was quickly deleted but hinted at the model’s scale and ambition.
- Qwen 4 demonstrated advanced creative and technical capabilities, including generating a Minecraft clone and a detailed Roman coliseum. However, minor flaws were noted in some outputs, such as shader issues and water mechanics in the Minecraft clone.
- The model excelled in simulations, reportedly simulating a bioreactor producing insulin with detailed controls and predictions. While these results are unvalidated for real-world use, they suggest potential for scientific and industrial applications.
- Rumors about Alibaba abandoning smaller models and open-weight development were reportedly debunked. Slides from the Esper conference confirmed that Qwen 4 and Qwen 5 will remain open-weight, reassuring the open-weight AI community.
The Qwen 4 lineup includes Qwen 4 Max, Qwen 4 Flash, Qwen 4 Plus, and Qwen 427B. Additionally, traces of a specialized Qwen Coder model have surfaced, suggesting a possible return of this variant. Several mysterious checkpoints, Kia, Kira, Enzia, and Meera, have been identified in Arena, potentially representing different sizes or configurations. During the Aspara conference in Amsterdam on October 29, 2026, Alibaba Cloud’s CTO reportedly announced the model’s launch for the following week, indicating a release window between November 2 and November 8, 2026. A broader public rollout is expected after early testing concludes.
A promotional image for Qwen 4 Max, reportedly leaked by an Alibaba partner, revealed several key specifications: a 1 million token context window, image support, tool-calling capabilities, and a promotional offer with free input and output tokens. Although the image was quickly deleted, it hinted at the Max variant’s potential. The poster also referenced the Kun, a legendary fish from ancient Chinese philosophy, described as unimaginably massive, possibly symbolizing the model’s scale and ambition.
Creative and Technical Capabilities
The Qwen 4 preview demonstrated notable creative and technical abilities. In one test, the model generated a Minecraft clone with features such as shaders, a day-night cycle, an inventory system, water dynamics, underwater visuals, water breathing mechanics, a health bar, multiple terrains, islands, mobs, tree types, a cave system, and diamonds. However, the clone had minor flaws, including an inability to exit water and a distracting shader hue.
In another test, the model created a detailed Roman coliseum with spectators, intricate architecture, atmospheric lighting, and flickering effects. This output, generated in “high thinking” mode, consumed about 69,000 tokens. Notably, the model produced such detailed environments without relying on its highest reasoning settings, showcasing its efficiency.
The Qwen 4 Curia checkpoint was tested against GPT 611 Terra at maximum reasoning effort. Qwen 4 generated a 2D RPG village in a single HTML file, with superior composition compared to its GPT counterpart. It also excelled in voxel art, producing outputs comparable to Sonnet and Haiku, and in SVG animations, where its results matched the quality of Sonnet 5.5.

Advanced Simulations and Token Efficiency
The preview highlighted strong performance in simulation tasks. Using the Hermes-powered version, it simulated a bioreactor producing insulin, with controls for oxygen, temperature, pH, stirring, and feed rates. It predicted a 36.6-hour batch yielding 18.4 grams of pro-insulin, potentially producing 5.3 grams of finished insulin, equivalent to approximately 3,800 daily doses. The system also triggered alarms when oxygen levels dropped, stalling bacterial growth. While these results are not validated for real-world applications, they suggest potential for scientific and industrial use.
Compared to earlier Qwen models, increasing the reasoning effort in Qwen 4 (“X high” or “max”) significantly improves output quality, though with longer generation times. While higher reasoning levels take more time than models like GPT and Opus, the results often justify the wait. In a web development task, Qwen 4 outperformed Deepseek 4.1 Flash, delivering better results while using roughly half the tokens. This efficiency strengthens its position for token-intensive tasks.
Game Development and 3D Generation
Qwen 4’s capabilities extend to game development and 3D generation. It successfully replicated the mechanics, shooting dynamics, and NPCs of a Call of Duty-style game, even at lower reasoning settings. For voxel art, the model produced creative outputs with variations in daylight cycles, comparable to those from Sonnet and Haiku.
In a 3D generation task, the model created a detailed environment of a boat with realistic water effects and lighting, using vanilla JavaScript and Three.js. This task demonstrated its superiority over GPT-6 Astra, achieving better results with significantly fewer tokens. Additionally, the model generated an SVG animation of a giraffe riding a bike with a rhino on top, matching the quality of Sonnet 5.5. These examples highlight its ability to handle both technical and whimsical creative challenges.
Rumors and Future Prospects
Rumors in Chinese communities suggested Alibaba might abandon smaller models and cease open-weight development. However, these claims were debunked, as the individual spreading the rumor reportedly had no connection to the original Qwen team. Slides from the Esper conference confirmed that both the Qwen 4 and Qwen 5 series will remain open-weight, reassuring the open-weight AI community.
Checkpoints for the Qwen 4 preview were recently updated and are accessible through battle mode in Arena. Sending requests in Arena may provide access to the Calmia model or Mura, both part of the Qwen series. These developments indicate that the Qwen 4 preview is part of a broader model series set to launch soon, with additional features and variants likely to emerge in the coming weeks.
World of AI concluded that the Qwen 4 preview represents a significant leap in open-weight AI capabilities, particularly in creative tasks, simulations, and token efficiency. While some outputs still exhibit minor errors, the model’s performance in generating detailed environments, simulations, and animations sets a new standard for open source AI. With its imminent launch, Qwen 4 could redefine expectations for open-weight models.
