On September 22, 2026, Alibaba said Qwen 4 was in training and projected a combined scale of 5–10 trillion parameters for the future Qwen 4.5 and Qwen 5 series. The figure is a roadmap projection for both series, not an individual model specification.
What the 5–10 trillion figure covers
Alibaba attached the range to the Qwen 4.5 and Qwen 5 series collectively. It gave no separate parameter count for either series, so the announcement does not assign the full range—or a specific number within it—to Qwen 5 alone.
What the roadmap says about smaller Qwen models
Alibaba’s announcement did not say that smaller Qwen models would be discontinued. Its stated development status was that Qwen 4 was in training on September 22, 2026.
