Magic Burger Explosion: Fiery Photorealism Challenge
Text-to-Image“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.”

AI Judge Analysis
Seedream 4.5
- + Excellent text rendering with impressive fiery effects and perfect accuracy.
- + High-quality photorealistic texture on the bun, meat, and vegetables.
- + Dynamic composition with motion-blurred ingredients that conveys the 'exploded' concept well.
- − The burger is mostly assembled rather than fully 'exploded' with all main layers separated.
Stable Diffusion 3.5 Large Turbo
- + Strong 'fiery' atmosphere with glowing embers and smoke.
- + Good centering of the subject matter.
- − Failed to include any of the requested text or the starburst element.
- − Image quality appears more like a digital illustration or 3D render than 'photorealistic'.
- − The burger is not 'exploded'; it is a static stack with a skewer through it.
Verdict: Seedream 4.5 is the clear winner as it followed every instruction, including complex text rendering and specific layout elements like the starburst. Stable Diffusion 3.5 Large Turbo failed to generate any text and produced a much less realistic image that did not capture the 'exploded' motion requested.
Chalkboard Menu
Text-to-Image“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.”

AI Judge Analysis
Seedream 4.5
- + Excellent text rendering with perfect spelling and realistic chalk texture.
- + Highly accurate adherence to the specific date and menu items requested.
- + Realistic chalkboard aesthetic with natural smudges and varied handwriting styles.
- − Redundant price for the first item listed on two lines.
Stable Diffusion 3.5 Large Turbo
- + Clean aesthetic for the cafe environment.
- − Significant spelling errors throughout the board (e.g., 'apri 3l', 'ocotpgs', 'lerbs').
- − Handwriting looks like a digital font rather than authentic chalk.
- − Failed to include the specific year 2026 correctly.
Verdict: Seedream 4.5 is the clear winner as it successfully rendered all requested text with high accuracy and a realistic chalk texture. In contrast, Stable Diffusion 3.5 Large Turbo struggled with basic spelling, failed to complete the date, and produced text that looks like a digital font instead of handwritten chalk.
