Qwen Image 2.0 Pro

[Core Function] Qwen Image 2.0 Pro is a professional-grade, highly controllable image generation model. [Strengths] It provides exquisite photorealism, professional infographics generation, supports NEGATIVE prompts, and can generate up to 6 image variants per API call. [Best For] Highly recommended for: workflows requiring strict negative prompt exclusion, batch generation (6 variants), and highly detailed infographics. [Limitations] Does not natively output 4K resolution (max is 2K). Does not have the explicit ‘Thinking Mode’ of Wan 2.7. [Routing] Route to this model specifically when the user provides a ‘negative prompt’ or asks for ‘batch generation of 6 images’.
