Parameter Normalization
How we handle parameters across different providers
Not every provider speaks the same language. When you send a parameter, we handle it in one of four ways depending on what the model supports:
| Behavior | What happens | Example |
|---|---|---|
passthrough |
Sent as-is to the provider | style, quality |
renamed |
Same value, mapped to the field name the provider expects | prompt |
converted |
Transformed to the provider's native format | size |
emulated |
Works even if the provider has no concept of it | n, response_format |
Parameters we don't recognize pass straight through to the upstream API, so provider-specific options still work.

Competition Results
“A glass cube on a wooden table. Inside the cube is a small blue sphere. On top of the cube sits a red book. A green plant is behind the cube, partially visible through the glass. Soft window light from the left.”
“Handwritten-style chalkboard menu in a cozy café, all text rendered in the exact same realistic chalk handwriting style with natural variations in letter size, slight slant, and chalk texture — no printed or digital fonts anywhere on the board. Title at the top in elegant cursive chalk handwriting: ‘TODAY’S SPECIALS – APRIL 30, 2026’. Below it, three menu items also in the same handwritten chalk style: ‘Truffle Mushroom Risotto – $24’, ‘Grilled Octopus with Lemon & Herbs – $28’, ‘Brown Butter Chocolate Chip Cookies – $9’. At the very bottom, smaller text in the identical handwritten chalk style (slightly smaller but still clearly legible with the same handwriting characteristics): ‘All items made fresh daily • Ask about our gluten-free options’. Warm ambient café lighting, visible chalk dust and smudges, realistic handwriting imperfections, no clean printed text anywhere.”
“Create a clear, 45° top-down isometric miniature 3D cartoon scene of Japan's signature dish: sushi, with soft refined textures, realistic PBR materials, gentle lighting, on a small raised diorama base with minimal garnish and plate. Solid light blue background. At top-center: 'JAPAN' in large bold text, 'SUSHI' below it, small flag icon. Perfectly centered, ultra-clean, high-clarity, square format.”
“Modern minimalist restaurant menu design, white background with colorful food photos in grid, sections for appetizers/pizza/mains, bold sans-serif fonts, vibrant accents, clean professional layout for casual dining.”
“Hyper-photorealistic scene of fluffy baby animals—a golden retriever puppy, tabby kitten, baby bunny, and red fox kit—with big expressive eyes and ultra-detailed soft fur, playfully chasing butterflies and tumbling together in a lush wildflower meadow, warm golden sunrise light with god rays and dew sparkles, joyful wholesome vibe, 8K masterpiece.”
“Photorealistic scene inside a yellow New York taxi at night. A capybara is driving, wearing a yellow taxi driver cap and a dark jacket. It has a calm, professional expression and both front paws on the steering wheel. In the back seat sits a human businesswoman in a coat, looking at her phone with a completely normal, bored expression (as if this is just another normal ride). Through the windows you can see the streets of Manhattan at night with blurred lights. Realistic taxi interior, photorealistic, detailed fur and fabric, 35mm lens, night lighting with reflections, shallow depth of field.”
“Ad for 'Magic Burger'. Dynamic, exploded burger with all components (bun, patty, cheese, lettuce, tomato, sauce) suspended in mid-air. Emphasize photorealistic detail and a sense of motion. Dark, fiery background with glowing embers. Integrate text: 'MAGIC BURGER' as a prominent title, 'LIMITED TIME ONLY' as a secondary message, and '€6.99' in a starburst, all rendered with a fiery, glowing effect.”
“Create a caricature of me and my job. Make it exaggerated and humorous, incorporating my profession as a tv show anchor and my love for dogs and hockey.”
“Use Image 1 as the base person. Dress them in the exact elaborate outfit from Image 2 (including all layers, accessories, jewelry, and shoes). Carefully adapt the clothing to the body shape and pose in Image 1 while maintaining realistic fabric behavior, correct proportions, and perfect lighting/shadow matching. Keep the person’s exact face, hair, and background completely unchanged.”
“Make a photo of the man driving the car down the California coastline”
“Add dynamic motion to this photo: make hair blow in the wind, add leaves flying, energetic and lively feel.”
“Transform this photo into a Studio Ghibli–inspired illustration. Use soft pastel colors, hand-painted textures, gentle lighting, dreamy backgrounds, and a warm, nostalgic mood”
“Vintage minimalist restaurant logo for "Caffè Florian", retro cloche dome with steam and "Est. 1720" banner, classic typography, warm brown and cream tones, subtle texture on light background, vector emblem style.”
“A glass cube on a wooden table. Inside the cube is a small blue sphere. On top of the cube sits a red book. A green plant is behind the cube, partially visible through the glass. Soft window light from the left.”
“A candid street photo of an elderly Japanese man repairing a red bicycle in light rain, reflections on wet pavement, shallow depth of field, 50mm lens, natural skin texture, imperfect framing, motion blur from passing cars, cinematic but realistic, no stylization.”

Overview
Gemini 2.5 Flash Image is a multimodal model developed by Google designed for high-velocity image generation and visual reasoning. It functions as an efficient mid-tier option in the Gemini lineup, prioritizing low latency and cost-effectiveness while maintaining the ability to process both text and image inputs. This model is distinctive for its dual-purpose nature, acting as both an image generator and a visual analysis tool within a single architecture.
Strengths
- Rapid Iterative Generation: Optimized for speed, the model excels at “flash” generation cycles where low latency is required for real-time applications or high-volume batch processing.
- Instruction Following: Strong adherence to system prompts allows for precise control over stylistic constraints and compositional requirements during the image creation process.
- Multimodal Reasoning: Unlike pure-play diffusion models, it can ingest existing images as context to perform editing, variations, or descriptive analysis.
- Resource Efficiency: Offers a significantly lower price point ($0.039 starting price) compared to larger-parameter models, making it viable for large-scale production deployments.
Limitations
- Visual Complexity: While fast, it may lack the intricate fine-detail rendering (such as complex micro-textures or hyper-realistic human anatomy) found in larger, “Pro” tier models.
- Compositional Nuance: In very dense scenes with numerous specific spatial requirements, the model may occasionally prioritize speed over exact adherence to complex spatial arrangements.
- Niche Stylization: Without specialized LoRA support or fine-tuning, it may struggle with highly specific or avant-garde artistic styles compared to dedicated community-driven generation models.
Technical Background
Released in October 2025, Gemini 2.5 Flash Image is built on the Gemini 2.x transformer-based architecture family. It utilizes a unified multimodal training approach that treats visual tokens and text tokens within the same latent space, enabling seamless transitions between understanding an input image and generating a visual response. The model is specifically tuned for distilled inference, reducing the computational overhead typically associated with large-scale vision-language models.
Best For
This model shines in scenarios requiring high-throughput asset generation, such as e-commerce product background variations, social media content scaling, and rapid prototyping for UI/UX concepts. It is also well-suited for applications that combine image analysis with immediate visual feedback, such as describing a scene and then modifying it based on user feedback.
Nano Banana (Gemini 2.5 Flash Image) is available for testing and deployment through Lumenfall’s unified API and interactive playground, allowing you to integrate its fast generational capabilities into your existing workflows alongside other models in the Gemini family.
