Poster / illustration
Flat illustration poster
Prompt: Flat vector-style travel poster of a coastal lighthouse on striped cliffs, a tiny sailboat on a patterned teal sea, big round sun in a coral sky, seagulls as simple curved marks, bold geometric shapes with a subtle paper texture, mid-century travel poster aesthetic, clean edges, limited palette of coral, teal, cream, and navy. No text.
Product mockup
Product visual on a budget
Prompt: Clean product photograph of a matte ceramic pour-over coffee dripper in terracotta, sitting on a walnut table with a linen cloth, a few roasted coffee beans scattered nearby, soft morning side light, gentle shadow, warm minimal lifestyle aesthetic, square composition for an online shop listing, realistic textures.
Social media graphic
Social graphic with short text
Prompt: Cheerful social media graphic for a fictional neighborhood farmers market: illustrated piles of tomatoes, peaches, and sunflowers forming a loose border around a cream center, with the words "SATURDAY MARKET" in large friendly hand-lettered capitals in the middle and "EVERY WEEK · 8 TO 1" in smaller type below. Warm harvest palette, folk-art flat illustration style, text crisp and correctly spelled.
Character / anime illustration
Anime-style character scene
Prompt: Anime-style illustration of a girl with a short silver bob and a oversized teal raincoat standing under a clear umbrella at a rainy train crossing at dusk, glowing vending machine light nearby, puddles reflecting neon signs, cinematic Makoto-Shinkai-inspired lighting with lush clouds after rain, detailed background art, gentle melancholic mood.
Packaging design concept
Bilingual tea packaging concept
Prompt: Elegant packaging design mockup for a white tea brand: a tall cylindrical paper canister in soft ivory with a minimal ink-wash mountain illustration wrapping the lower half, the English words "WHITE PEONY TEA" in a refined serif on the front and the Chinese characters "白牡丹" in elegant calligraphy beneath them, a thin gold band at the lid. Soft studio light, seamless pale background, premium minimal East-Asian design, all characters correctly rendered.
Interior / lifestyle concept
Cozy interior scene
Prompt: Warm illustration of a tiny bakery kitchen in the early morning: wooden shelves stacked with mixing bowls, a window with soft blue dawn light, croissants proofing on a tray, flour dust in the air, a cat asleep on a stool, storybook gouache style with soft edges and a honey-and-cream palette, inviting and detailed.
Hunyuan Image 2.1 is Tencent's open-weights image generation model — its parameters are published, so the community can audit, fine-tune, and self-host it instead of relying on a proprietary black box.
On RenderFlow AI you get that open model as a hosted convenience: 3 credits per image, width and height from 256 to 1536 pixels, JPEG, PNG, or WebP output, and a seed field — no GPU bill or deployment work attached.
Width and height run from 256 to 1536 pixels, and smaller frames generate faster. Avatars, thumbnails, and UI spot illustrations render fine at 512–768 — save 1536 for images that will be seen large.
Set WebP for anything headed straight to a website, PNG for design-tool handoff with crisp edges, and JPEG for photographic shares. Hunyuan is one of the few models on RenderFlow AI offering all three.
State subject, environment, and style plainly; Hunyuan 2.1 responds to clear instructions in either language rather than dense keyword stacks. Keep any in-image text requests short.
When testing wording changes, lock the seed so differences come from your edit instead of the dice. Reset it to -1 for fresh randomness once the comparison is done.
If the winning draft needs 2K/4K output or gallery-grade close-up detail, move the prompt to Flux Pro Ultra or Imagen 4 Ultra. Hunyuan's job is the efficient middle, not the ceiling.
Yes. Tencent published the Hunyuan Image 2.1 weights, so the model can be inspected, fine-tuned, and self-hosted. RenderFlow AI runs a hosted deployment, which lets you use it per generation without standing up your own infrastructure.
Width and height each range from 256 to 1536 pixels, and output can be JPEG, PNG, or WebP. A seed field is available when you need reproducible results across prompt experiments.
Both are open-leaning Chinese models at 3 credits. Pick Hunyuan Image 2.1 for general scene and illustration work with WebP output; pick Qwen Image when the design needs embedded text, posters, or bilingual typography.
Beyond its 1536-pixel ceiling — there is no 2K or 4K here — and on long in-image text or hyper-detailed close-ups. For those jobs, move the winning prompt to Flux Pro Ultra or Imagen 4 Ultra.
Yes. Tencent trains the Hunyuan family with strong Chinese-English bilingual coverage, so Chinese-language prompts work naturally — useful for bilingual teams reviewing the same outputs.
