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 5.0 Lite
- + Features very realistic chalk texture and natural handwriting variations.
- + Excellent prompt adherence for the specific handwritten, imperfect style requested.
- + The board itself looks authentic with smudges and aged edges.
- − Contains several spelling errors like 'Heriss', 'Beliter', and 'frese opstoons'.
- − Handwriting is a bit messy and lacks the 'elegant cursive' requested for the title.
Wan 2.7
- + Flawless spelling and complete rendering of all requested text.
- + Clean, legible composition with a nice café background.
- + Correctly interpreted the 'Brown Butter' item which was cut off in the prompt.
- − The text looks like a digital font rather than authentic hand-drawn chalk.
- − Fails the negative constraint of 'no printed or digital fonts anywhere'.
- − Characters are too uniform and lack the gritty texture of real chalk.
Verdict: Seedream 5.0 Lite captures the soul of the prompt with authentic chalk textures and realistic handwriting, but suffers from significant spelling issues. Wan 2.7 provides perfect spelling and a polished layout, but the text appears to be a digital font overlay, violating the core requirement for a natural handwritten look. Seedream 5.0 Lite is the preferred choice for its superior artistic texture despite the typos.
Outfit Transfer Challenge
Editing“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.”
AI Judge Analysis
Seedream 5.0 Lite
- + Excellent adherence to the clothing style, colors, and accessories from Image 2
- + Perfect preservation of the person's face, skin patterns, and background
- + Seamlessly integrates the lighting from the beach onto the new clothing
- − The hand reconstruction is slightly bulky compared to the original
Wan 2.7
- + Generates a high-quality elaborate outfit that fits the 'elaborate' description
- − Completely fails to use the specific outfit provided in Image 2
- − Changes the subject's pose significantly
- − Alters the skin patterns on the hands and body, diverging from Image 1
Verdict: Seedream 5.0 Lite followed all instructions perfectly, accurately transferring the pea coat, plaid scarf, sunglasses, watch, and ring from Image 2 onto the subject in Image 1 while keeping the face and background identical. Wan 2.7 ignored the visual reference of the clothing entirely, generating a generic fantasy outfit and changing the subject's pose.
The Capybara Taxi Driver
Text-to-Image“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.”
AI Judge Analysis
Seedream 5.0 Lite
- + Excellent interior composition that accurately places the passenger in the back seat.
- + High levels of photorealism in the capybara's fur and the cockpit details.
- + Accurately renders the ‘bored’ expression of the businesswoman as requested.
- − The perspective makes the capybara appear slightly oversized for the vehicle.
- − The cap looks a bit like a modern baseball cap rather than a traditional taxi driver hat.
Wan 2.7
- + Natural street-side perspective through the window.
- + Good detail on the capybara's hands/paws and steering wheel interaction.
- + Includes a more traditional chauffeur-style taxi cap.
- − The passenger is sitting in the front passenger seat instead of the back seat as requested.
- − The capybara's fur texture looks slightly more digital/artificial compared to Model A.
- − The background lighting is less evocative of 'Manhattan at night' than Model A.
Verdict: Seedream 5.0 Lite followed the prompt instructions more accurately, specifically by placing the businesswoman in the back seat rather than the front. Wan 2.7 has good detail but fails on the spatial layout requested by the prompt. Seedream 5.0 Lite also achieved a more convincing cinematic night-time atmosphere.
