Qwen3.8-Flash-Next weights offer a Qwen4 architecture preview
Qwen provides an experimental multimodal MoE preview and an FP8 variant. Its model card now specifies 125B language-model parameters with 6B active, plus 51B n-gram embeddings and 4B MTP parameters, under Qwen Community License 1.0.

Why it is worth understanding
Developers working on deployment, quantization, or inference compatibility can inspect the architecture and measure task performance. A replacement decision also needs hardware, output-quality, and licensing checks.
Conditions and limitations
The 6B active figure does not imply a 6B model’s memory footprint. The release is experimental. Its license requires separate permission for commercial use by businesses offering model services or defined AI work assistants, with an internal-use exception. We have not tested performance or cost improvements.
Important additions and corrections
Dates below mark changes to our coverage.
- Correction ·
Added officially documented parameters and license conditions: 6B active parameters do not imply a 6B model’s memory needs, and some commercial uses require separate permission.

Current official model cards and the license supersede the unsupported-specification caveat. “Available weights” avoids implying a permissive open-source license.
