A post in r/LocalLLaMA says Alibaba officially announced Qwen 4 at the Apsara Conference. The supplied material contains no launch date, architecture details, licensing information, model sizes, or evaluation results.

The discussion focuses on a possible Qwen4-27B. Commenters ask about n-gram support and mention possible variants such as Qwen4-35B-A3B and Qwen4 50b a5b. Some connect the 27B model with systems carrying 24 to 32 GB of VRAM and question whether cards with 12 GB or less could run it. The supplied material attributes these details to Reddit users. It contains no Qwen specification.
