Head to head: Seedream 5.5 Edit vs Ideogram V4.5 Edit
Seedream 5.5 Edit vs Ideogram V4.5 Edit
By Ryan Merket · Published
Across eight varied edits—from reflective still lifes and exact-count arrangements to signage, spatial layouts, palette, and mood—the matchup tests how each model balances precise prompt-following with visual polish.
Seedream 5.5 Edit leads **63.0 to 59.1**, taking six task wins to Ideogram V4.5 Edit’s one, with one tie. That is a decisive editorial result on this sample, not a statistical claim. Seedream’s edge comes from repeatedly getting the requested details into the frame: legible reflections in a close-up still life, seven cleanly countable cups, crisp sign text in a convincing depot setting, and the specified left-to-right yard layout. It also earned the calls on the woodblock-style fishing scene and the rain-soaked ferry-driver portrait. Ideogram’s clearest success was the Hilda Basin poster, where its strict palette, centered layout, and framing beat Seedream’s richer but busier treatment. The hands task was a tie: Ideogram made the grip easier to read, while Seedream felt more like a natural candid moment. **The call: Seedream 5.5 Edit wins this head-to-head, on the strength of more consistent prompt fidelity across the saved task sample. This assessment applies to that saved sample only.**
Reflections & glass
A photorealistic close-up of a chrome teapot on a polished dark marble counter next to a glass of water; the window and a red apple on the counter must be correctly reflected in BOTH the chrome and the water's surface, dramatic side light, 16:9.
OpenAI: GPT-6 Luna: Model A more fully matches the close-up still-life prompt, with dramatic side light, a polished dark marble counter, and especially legible window and apple reflections in the chrome and on the water. Model B includes the requested objects and reflections, but the subjects are smaller and less visually impactful in the frame. (Second judge pass, order swapped — scores are the average of both: Model A has a stronger close-up composition and more dramatic side lighting, with the window and a recog | Anthropic: Claude Fable 5.1: Model A delivers a convincingly photorealistic…
Exact counting
A clean overhead flat lay on white marble of EXACTLY seven identical espresso cups arranged in a single straight row, each clearly separate and individually countable, even soft lighting, 16:9.
OpenAI: GPT-6 Luna: Model A shows exactly seven clearly separated, matching espresso cups in a straight overhead row on white marble, with no distracting extras. Model B also has seven cups, but the added spoons and smaller, less prominent cups make it less faithful to the clean, countable composition. (Second judge pass, order swapped — scores are the average of both: Model B shows exactly seven cups in a straight row, but the added spoons make the arrangement busier. Model A presents exactly seven clearly countab | Anthropic: Claude Fable 5.1: Both Model A and Model B deliver exactly seven…
Typography—freight depot warning sign
A photoreal close frontal shot of a brushed-aluminum safety sign bolted to a chain-link gate at the Brackett Intermodal Depot, lit by cool overcast daylight for maximum readability; the sign must contain exactly three lines of large, crisp, legible sans-serif text reading: “BAY 14” on the first line, “NO IDLING” on the second line, and “ENGINES OFF” on the third line; black text on matte yellow background, no extra words, no misspellings, no decorative flourishes, sharp focus.
OpenAI: GPT-6 Luna: Model A more closely matches the brushed-aluminum sign and depot setting, with all three requested lines crisp and correctly rendered. Model B also has exact, legible text and a strong frontal composition, but its sign appears less metallic and the setting is less distinctive. (Second judge pass, order swapped — scores are the average of both: Both images render the three requested lines correctly and legibly, but Model A better conveys the intermodal depot setting and gives the sign a convincin | Anthropic: Claude Fable 5.1: Both renders nail the exact three-line text wit…
Hands & anatomy
A natural candid photo of a person tying a friendship bracelet, both hands clearly visible with anatomically correct fingers and a plausible grip on the threads, soft daylight, shallow depth of field, 16:9.
OpenAI: GPT-6 Luna: Model B shows both hands clearly with a plausible grip as the bracelet is worked, while Model A has a more cinematic look but one hand obscures much of the other hand’s fingers. Model A’s soft outdoor lighting is appealing; Model B’s brighter, well-focused craft setup adheres more directly to the prompt. (Second judge pass, order swapped — scores are the average of both: Model A feels more like a natural candid moment, with a convincing thread-working gesture, soft daylight, and attractive shall | Anthropic: Claude Fable 5.1: Model B makes both hands the clear subject at l…
Spatial—maintenance yard layout
An isometric illustration of a compact rail maintenance yard in bright morning light, with precise object placement: a red shunter locomotive is left of a yellow fuel tank; a blue tool cart is directly between the locomotive and the fuel tank; a silver ladder is leaning against the fuel tank; a mechanic in orange coveralls stands behind the blue tool cart; a black toolbox sits on top of a wooden crate; that crate is right of the mechanic and in front of a green maintenance van; a white hard hat lies on the ground between the crate and the van; clean industrial detail, sharp edges, easy-to-verify layout, 16:9.
OpenAI: GPT-6 Luna: Model A better satisfies the key left-to-right placement of the locomotive, tool cart, and fuel tank, and includes a convincing rail-yard setting with crisp industrial detail. Model B is cleaner and more isometric, but places the tool cart beyond the fuel tank and omits visible rails. (Second judge pass, order swapped — scores are the average of both: Model A places the blue tool cart between the locomotive and fuel tank, with the mechanic behind it, and clearly includes the crate, toolbox, van, | Anthropic: Claude Fable 5.1: Model A satisfies more of the spatial chain (lo…
Palette—Hilda Basin tram poster
A clean flat-lay 1980s retro print travel poster of a streamlined tram gliding across the Hilda Basin causeway at sunrise, composed strictly and only in the named color palette: cream, charcoal, teal, rust, mustard, and dusty mauve; no other colors anywhere, including highlights, shadows, sky, water, reflections, and typography; bold geometric shapes, crisp screen-printed texture, high contrast, centered composition, 16:9.
OpenAI: GPT-6 Luna: Model A more clearly depicts a tram crossing the basin on a causeway, with a richly composed sunrise scene and polished retro screen-print styling. Model B is clean and uses the palette effectively, but its simplified scene conveys the causeway setting less clearly. (Second judge pass, order swapped — scores are the average of both: Model B more closely follows the strict limited palette, centered layout, and requested 16:9 framing. Model A is more atmospheric and detailed, but its busier scene | Anthropic: Claude Fable 5.1: Model B stays rigorously within the six-color pa…
Named art style
A ukiyo-e woodblock print of a fishing boat riding a large cresting wave at dawn, faithful to the flat color planes, bold outlines, and stylized foam of the tradition, muted indigo and cream palette.
OpenAI: GPT-6 Luna: Model A more fully captures the dawn setting with its muted indigo-and-cream palette, fishing crew, and layered woodblock-style waves, while Model B has a strong, cleanly stylized crest but a warmer boat and a less developed setting. Model A also has the more engaging composition, with the boat dramatically nestled among the waves. (Second judge pass, order swapped — scores are the average of both: Model B captures the bold, flat ukiyo-e look especially well, with a dramatic wave and a boat ridi | Anthropic: Claude Fable 5.1: Model A delivers a richer, more authentic Hokus…
Emotion—missed ferry driver
A rain-speckled close-up cinematic portrait of a municipal ferry-bus driver standing beside a turquoise amphibious shuttle at a harbor ramp just after the gate has closed, convincingly conveying crushed, unmistakable disappointment mixed with exhausted disbelief—slumped shoulders, parted lips, damp eyes, tense jaw, brows drawn upward at the center—while clutching a punched ticket roll marked Route 7C; reflective wet pavement, sodium-vapor dock lights, shallow depth of field, natural skin texture, documentary realism, 16:9.
OpenAI: GPT-6 Luna: Model A better matches the requested rain-speckled close-up and conveys restrained, exhausted disappointment beside the turquoise shuttle, with a readable Route 7C ticket roll and cinematic dock lighting. Model B makes the disbelief more overt, but its wider framing and more startled expression miss the requested portrait-like composition and crushed mood somewhat. (Second judge pass, order swapped — scores are the average of both: Model B conveys the requested crushed disappointment and exhaust | Anthropic: Claude Fable 5.1: Model A delivers the requested close-up cinemat…
