Youchuan V8.1 Image-to-Video, in practice.
> About Youchuan (悠船): "Youchuan V8.1" is Midjourney's V8.1 model delivered through Youchuan (悠船), Midjourney's officially authorized platform in China — self-branded *"Midjourney 中国实验室" (Midjourney China Lab)* and operated by Xiaochuan Creative (Shanghai) Network Technology Co., Ltd. (小船创意). Youchuan is a legitimate, licensed distributor of Midjourney's models (not a third-party clone): it offers the same Midjourney technology, localized for the Chinese market with priority access to new model versions. Youchuan V8.1 is the latest iteration of Midjourney's image-synthesis model. This README covers the two core generation endpoints: It belongs to a larger Youchuan V8.1 family on this platfor
- Native 2K HD output without a separate upscaler: V8.1 generates directly at 2048px resolution, eliminating the dedicated upscaling step required by earlier versions. HD renders take roughly 1.33 GPU-minutes and standard-definition renders under 1 GPU-minute, with HD running approximately 3× faster and cheaper than in V8.
- ~4–5× faster generation: The GPU-native PyTorch rewrite delivers an estimated four-to-fivefold speedup in generation time over previous Midjourney versions (a Midjourney-stated figure, not an independent benchmark), improving iteration speed for creative workflows.
- Improved text rendering: V8.1 renders in-image text more reliably, with quoted strings in prompts used to specify the intended text — narrowing a long-standing weakness relative to text-specialized competitors.
- Stronger prompt-following: The model adheres more closely to prompt instructions, improving controllability and reducing the prompt-engineering effort needed to achieve a target composition.
- Restored image conditioning: Image prompts and image weights — absent in the V8.0 alpha — returned in V8.1, alongside backward compatibility with V7 style references (srefs), moodboards, and personalization profiles. (Image-driven generation is offered here as the dedicated `youchuan/v8.1/image-to-image` and `blend` models.)
- Workflow tooling: V8.1 ships with a Prompt Shortener and an updated `/describe` command, and its aesthetic has been re-tuned "in the spirit of V7" to preserve the look users prefer.
