Craft Natural Language Prompts
Serin transforms your words into stunning Manhwa-inspired visions. Unlike traditional keyword-stuffed prompts, it thrives on lyrical storytelling – much like its sibling model Tsubaki. Instead of fragmented keywords, weave scenes with:
- Character emotions + actions
- Environmental details
- Atmospheric interactions
(For Tsubaki prompt techniques, see this guide)
Instead of:
“1girl, brown hair, dark-skinned female, smoke“
Write like this:
“A dark-skinned young woman with very long brown hair stands against a railing, smiling as she holds a cigarette between her lips. She wears a cropped grey short-sleeved shirt that exposes her midriff, cleavage, and navel, along with multiple pieces of jewelry—a bracelet, earrings, necklace, and rings. Her nails are painted, and her grey eyes gaze confidently at the viewer. Smoke drifts from the cigarette as she leans slightly forward, her upper body framed by a black border.The image has a moody, urban aesthetic with sharp details in her clothing, accessories, and expression.”
Multi-Character Example
Serin also shines when illustrating interactions between characters. When writing prompts, describe each person individually before connecting them through the environment or action.
“Two young men stand close together in a blue-lit background, their intense gazes locked. Ivan, with short black hair and sharp black eyes, wears a black beanie, a sleeveless black turtleneck shirt, and a black jacket with a red necktie loosely hanging. His left hand grips Till’s necktie, pulling him closer. Till, with messy grey hair and striking green eyes, wears a similar sleeveless black turtleneck, his spiked choker adding an edgy contrast. His fingers clutch Ivan’s jacket collar, their dynamic pose exuding tension and intimacy. Both have aqua-colored nails, adding a subtle pop of color. Ivan smirks with confidence, while Till’s expression is more defiant, lips slightly parted. The atmosphere is charged with a mix of rivalry and unspoken attraction, emphasized by the dramatic lighting and the sharp contrast of their dark outfits against the cool blue backdrop. The image is polished, with detailed textures in their clothing and expressive facial features.“
Enhanced Prompt Processing with Prompt Helper
While crafting descriptive, natural language prompts yields the best results with Serin, we understand that transitioning from traditional tag-based prompting can take practice. If you’re more comfortable with tag formats or want to gradually adapt your prompting style, simply leave the Prompt Helper enabled.
Leaving the Prompt Helper enabled will convert prompts (even those consisting only of tags) into more descriptive natural language that’s optimized for Serin. Additionally, the Prompt Helper supports multiple languages – you don’t need to limit yourself to English. Whether you write in your native language or any other language you’re comfortable with, the Prompt Helper will transform it into the optimal prompt format that Serin understands best.
You can now see the result of the Prompt Helper’s rewriting directly in the generation panel.Look for the Prompt Helper output in the bottom-right corner of the generation panel.
Once Prompt Helper processes your input, you can view the enhanced prompt and easily reuse it for future generations.
Comparison of Serin with other PixAI In-house Models
What makes Serin special among PixAI’s in-house model collection? Understanding how Serin differs from our other models will help you choose the right tool for your creative vision.
Korean Aesthetic Excellence
Unlike other models in the PixAI ecosystem, Serin naturally produces artwork with authentic Korean aesthetic qualities. While its sibling model Tsubaki, also built on the DiT architecture, shares similar technical foundations, Serin’s training has been specifically optimized for Korean visual styles.
Serin
Tsubaki
You don’t need to explicitly prompt for “manhwa style,” “webtoon style,” or other Korean-specific tags to achieve authentic Korean aesthetics. This represents a significant advantage over other PixAI in-house models, which typically default to Japanese anime art styles and require specific prompting to achieve alternative aesthetic directions.
Example: The K-pop Tag Effect
Prompt
1girl blunt_bangs brown_eyes brown_hair closed_eyes hat long_hair long_sleeves looking_at_viewer pink_lips solo sweater turtleneck turtleneck_sweater upper_body white_sweater
After adding tag kpop:
1girl blunt_bangs brown_eyes brown_hair closed_eyes hat k-pop long_hair long_sleeves looking_at_viewer pink_lips solo sweater turtleneck turtleneck_sweater upper_body white_sweater
Our testing demonstrates this capability clearly. In the first comparison image, we can observe how adding the “k-pop” tag to a basic prompt transforms the output across different models:
- Original prompt: Generated standard anime-style characters
- With k-pop tag: Serin maintained superior consistency in Korean aesthetic rendering across all four model variants (Serin, Tsubaki, Haruka V2, and Hinata V2)
The results show that Serin produces the most authentic Korean visual characteristics, with natural facial features, styling, and overall composition that aligns with contemporary Korean illustration standards.
Superior Natural Language Processing
When compared to specialized models like Otome V2, Serin demonstrates significantly better natural language processing capabilities. While Otome V2 excels specifically at male character generation, it often struggles with complex, descriptive prompts written in natural language rather than tag-based formats.
One of Serin’s most notable advantages is its natural tendency to generate mature male characters. Unlike Otome V2, which defaults to younger-appearing male characters unless explicitly prompted otherwise, Serin produces age-appropriate adult male figures without requiring specific descriptors like “mature male,” “adult,” or “muscular male.”
Prompt
Tag prompt: black_eyes black_hair black_jacket chibi closed_mouth comic grey_hood grey_hoodie hands_in_pockets hood hood_down hoodie jacket long_sleeves male_focus mini_person mini_person_in_clothes multiple_boys short_hair simple_background sleeping sound_effects
Natural language: A boy with short black hair and black eyes, wearing a grey hoodie and a black jacket with the hood down. In his jacket pocket, a tiny chibi boy peeks out, dressed in matching clothes. The main boy has his hands in his pockets and a calm closed-mouth expression. The scene is illustrated in a comic style with simple background and playful sound effects.
Multi-Character Scene Composition
Serin’s ability to handle multiple characters in a single scene surpasses most SDXL-based models. This capability is particularly evident in relationship-focused compositions, where character interactions, positioning, and individual detail retention remain consistent and accurate. The couple scene comparison reveals Serin’s superior ability to maintain character consistency and accurate prop handling in complex scenarios. While other models struggled with basic object assignment and character positioning.
Prompt:
A young couple indoors, standing close together with an intimate and tender atmosphere. The boy has short black hair and warm brown eyes, his lips softly closed, holding a smartphone in his hand as he lifts it slightly to take a picture of the two of them. Beside him is a girl with long flowing purple hair that falls between her eyes, one eye gently closed while the other looks at the viewer. She smiles softly with a relaxed, affectionate expression. Their bodies lean slightly toward each other, creating a sense of closeness and warmth, like a couple comfortable in each other’s presence. The lighting is soft and gentle, emphasizing the warmth in their eyes and their tender mood. The background is kept minimal and simple to highlight the two figures and their intimate pose.
