Qwen shipped Qwen-Image-2.1-PE-T2I and Qwen-Image-2.1-PE-I2I, dedicated prompt-enhancer adapters for the Qwen-Image-2.1 T2I/editing pipeline: a fine-tuned Qwen3.5-VL 9B that rewrites a short user prompt into a detailed English prompt plus a recommended aspect ratio, output as JSON. Text output only, gated behind the Qwen Research License; the HF API page came back empty on fetch, so the summary is based on model metadata rather than a full card.

Why it matters

Keeps building out the open Qwen image-generation stack with a prompt-enhancer companion that previously would have required a separate closed tool.

Importance: 2/5

Minor companion release within an existing image-model line
