### Physics realism Winner: **Gemini Omni Flash**. OpenAI: GPT-5.6 Sol Pro: Model B clearly depicts soda, a visible drop and splash, rising fizz, and buoyant settling in a softly lit kitchen, though the cube deforms and appears to multiply between frames. Model A lacks the requested soda appearance and believable drop-bob sequence, with an indistinct object remaining near the bottom and minimal temporal change. (Second judge pass, order swapped — scores are the average of both: Model B clearly depicts an ice cube entering dark soda, producing a splash and bubbles before | Anthropic: Claude Fable 5.1: Model A shows a static, near-abstract clos… ### Temporal consistency Winner: **Gemini Omni Flash**. OpenAI: GPT-5.6 Sol Pro: Model B strongly matches the requested 16:9 tracking shot and preserves the man's face, coat, and umbrella with excellent consistency across frames. Model A depicts clearer walking motion but uses a square frame and shows noticeable background, footwear, umbrella, and facial-detail instability. (Second judge pass, order swapped — scores are the average of both: Model B closely follows the requested 16:9 tracking-shot composition and maintains highly consistent facial features, raincoat, and umbr | Anthropic: Claude Fable 5.1: Model B delivers the requested 16:9 framin… ### Cat and runaway persimmon Winner: **Gemini Omni Flash**. OpenAI: GPT-5.6 Sol Pro: Model B clearly depicts the cat batting the persimmon from the chipped blue table, the fruit moving across terracotta tiles toward a metal water bowl, and a coherent downward camera transition with strong visual fidelity. Model A is temporally stable and warmly lit but omits nearly all of the requested action and key props, while also lacking the specified 16:9 framing. (Second judge pass, order swapped — scores are the average of both: Model B clearly depicts the Scottish Fold batting the persi | Anthropic: Claude Fable 5.1: Model A shows a tabby cat sitting on the f… ### Dog behind laundry rack Winner: **Gemini Omni Flash**. OpenAI: GPT-5.6 Sol Pro: Model A is visually clean but depicts a nearly static, front-facing dog with the wrong coloring and harness, omitting the sprint, lure, sheets, rack, and occlusion. Model B closely matches the rooftop setting, brindle whippet, teal harness, green lure, rolling sheets, left-to-right chase, and coherent re-emergence, with only minor ambiguity around the lure and occluded pose. (Second judge pass, order swapped — scores are the average of both: Model B closely depicts the rooftop chase, rolling she | Anthropic: Claude Fable 5.1: Model A shows a static, non-brindle dog st… ### Physics realism Winner: **Gemini Omni Flash**. OpenAI: GPT-5.6 Sol Pro: Model B closely matches the soda, kitchen, splash, buoyancy, and rising-bubble requirements with a convincing cinematic presentation, though the apparent extra cubes and shape changes reduce physical and temporal realism. Model A is stable but appears nearly static, lacks the requested 16:9 composition and clear soda appearance, and does not visibly demonstrate the drop-and-bob sequence. (Second judge pass, order swapped — scores are the average of both: Model B closely matches the soda, splash, | Anthropic: Claude Fable 5.1: Model A shows a static, oddly geometric ic… ### Temporal consistency Winner: **Gemini Omni Flash**. OpenAI: GPT-5.6 Sol Pro: Model B maintains a remarkably stable face, raincoat, umbrella, framing, and cinematic 16:9 composition, though the walking motion appears somewhat minimal. Model A shows clearer forward steps but has conspicuous coat and clothing morphing, weaker facial continuity, and an incorrect square aspect ratio. (Second judge pass, order swapped — scores are the average of both: Model B strongly matches the requested 16:9 rainy tracking shot and keeps the face, yellow coat, and black umbrella exceptional | Anthropic: Claude Fable 5.1: Model B delivers a sharp, 16:9 shot where… ### Cat and runaway persimmon Winner: **Gemini Omni Flash**. OpenAI: GPT-5.6 Sol Pro: Model B clearly depicts the requested progression from the cat batting the persimmon on the chipped blue table to the fruit rolling across terracotta tiles and reaching the metal water bowl, with strong cinematic lighting and consistency. Model A shows only a largely static cat on the floor, omitting the persimmon, table interaction, bowl contact, camera progression, and requested 16:9 composition. (Second judge pass, order swapped — scores are the average of both: Model B clearly presents the r | Anthropic: Claude Fable 5.1: Model A shows a static cat standing on the… ### Dog behind laundry rack Winner: **Gemini Omni Flash**. OpenAI: GPT-5.6 Sol Pro: Model B closely fulfills the rooftop chase, side-tracking composition, sheet-rack occlusion, warm lighting, and consistent brindle dog design with convincing running poses. Model A lacks the laundry rack and side-to-side chase, while the green lure appears fused or duplicated around a mostly frontal, minimally changing dog. (Second judge pass, order swapped — scores are the average of both: Model B closely matches the rooftop chase, teal harness, green lure, side-tracking composition, sheet-rack | Anthropic: Claude Fable 5.1: Model A shows a merle-ish terrier-like dog…
Physics realism
A close-up of a single ice cube dropped into a tall glass of soda: it falls, splashes, bobs, and settles with believable buoyancy and fizzing bubbles rising naturally, soft kitchen light, 16:9.

Temporal consistency
A man in a yellow raincoat walking toward camera down a rainy street; his face, coat, and umbrella must stay perfectly consistent with no morphing or flicker from the first frame to the last, steady tracking shot, 16:9.

Cat and runaway persimmon
A short continuous-shot 16:9 clip in a dim amber-lit kitchen just before dawn: a stocky gray Scottish Fold cat bats a ripe persimmon off a chipped blue enamel table, and the fruit falls, hits the terracotta tile floor, bounces, rolls in a believable curved path, and lightly taps a metal water bowl causing a small realistic wobble and slosh, while the cat’s body reacts with natural weight and momentum; the camera starts at tabletop height and tilts down, then slowly dollies forward to follow the persimmon’s motion, with quiet suspenseful mood and soft window light mixing with a single warm under-cabinet lamp.
OpenAI: GPT-5.6 Sol Pro: Model B clearly depicts the cat batting the persimmon from the chipped blue table, the fruit moving across terracotta tiles toward a metal water bowl, and a coherent downward camera transition with strong visual fidelity. Model A is temporally stable and warmly lit but omits nearly all of the requested action and key props, while also lacking the specified 16:9 framing.

Dog behind laundry rack
A short one-shot 16:9 video in a sunlit rooftop laundry space at golden hour: a wiry brindle whippet wearing a teal harness sprints left to right chasing a lime-green felt lure, then passes fully behind a rolling rack hung with six fluttering white bedsheets and re-emerges on the other side unchanged in size, markings, harness position, and stride, never duplicating or warping through the occlusion; the camera makes a smooth low tracking move parallel to the dog with a slight handheld sway, warm backlight glowing through the sheets, breezy playful mood.
OpenAI: GPT-5.6 Sol Pro: Model A is visually clean but depicts a nearly static, front-facing dog with the wrong coloring and harness, omitting the sprint, lure, sheets, rack, and occlusion. Model B closely matches the rooftop setting, brindle whippet, teal harness, green lure, rolling sheets, left-to-right chase, and coherent re-emergence, with only minor ambiguity around the lure and occluded pose. (Second judge pass, order swapped — scores are the average of both: Model B closely depicts the rooftop chase, rolling she | Anthropic: Claude Fable 5.1: Model A shows a static, non-brindle dog st…
