Head to head: Kling Video v2.6 Image to Video vs LTX 2.5 Image to Video Pro
Kling Video v2.6 Image to Video vs LTX 2.5 Image to Video Pro
By Ryan Merket · Published · Updated
Kling Video v2.6 Image to Video and LTX 2.5 Image to Video Pro face off across industrial camera moves, a dusk lighting change, and latte art. The comparison turns on which model handles those specific prompt demands more consistently.
Kling has the higher aggregate score—**28.7** to **26.8**—but the saved result is a tie on this task sample. The task outcomes were 7 wins for Kling, 3 for LTX, and 2 ties; that record doesn’t justify declaring an overall winner.
Orbit around valve rigger
A short one-shot video inside Bay 6 of the Kessler Forge turbine hall: a grease-streaked valve rigger in a cobalt jacket braces and turns a giant handwheel as a suspended chain hook swings lightly beside him and sparks spit briefly from a grinder far in the background; the camera executes a smooth orbit around the subject, circling from his front-left to his back-right at a constant pace exactly as described, no other camera move, under hard sodium-vapor work lights with deep amber reflections on steel, tense determined mood, 16:9
OpenAI: GPT-6 Luna: Model B shows a clear progression from the rigger’s front-left to his side and then back, with the handwheel prominent and consistent warm industrial lighting. Model A has an atmospheric turbine hall and suspended hook, but keeps the worker distant and mostly rear-facing, making the requested orbit and valve-turning action less clear. (Second judge pass, order swapped — scores are the average of both: Model B clearly shows the rigger bracing and turning a giant handwheel, with a smooth front-to- | Anthropic: Claude Fable 5.1: Model B executes the described front-left to ba…
Brine tower dawn drift
A short continuous shot of a rust-red evaporative cooling tower at the abandoned Neris-12 desalination yard, where a maintenance rover the size of a lawnmower crawls along a wet grated catwalk while orange warning LEDs blink; pale dawn light glows through thin drifting clouds, steam rises in uneven plumes from relief vents, puddles tremble with concentric ripples, and a fringe of salt-stunted tamarisk trees beyond the fence sways steadily in the wind, all background motion natural and continuous, with a subtle slow dolly-in toward the rover, cool industrial mood, 16:9
OpenAI: GPT-6 Luna: Model A more closely matches the prompt’s enormous rust-red evaporative cooling tower, grated catwalk, warning lights, and venting steam. Model B shows clearer rover movement and a strong dawn mood, but its tower is much less like the specified cooling tower and its background trees are a weaker match. (Second judge pass, order swapped — scores are the average of both: Model B more clearly delivers the gradual dolly-in and the rover’s approach, with wet grating, warning lights, dawn light, and d | Anthropic: Claude Fable 5.1: Model A nails the rust-red hyperbolic cooling t…
Lighting transition
A living room at dusk as the sun sets over a few seconds: the warm light visibly dims and shifts to cool blue while a lamp flickers on, the transition smooth and believable, locked-off frame, 16:9.
OpenAI: GPT-6 Luna: Model B shows a clearer dusk-to-blue transition with the lamp visibly turning on and remaining warmly lit, though its framing shifts despite the locked-off request. Model A keeps the composition fixed, but the lamp is already on and turns an unnatural blue by the final frame. (Second judge pass, order swapped — scores are the average of both: Model B more clearly shows the warm sunset giving way to cool dusk while the floor lamp switches on, though the lighting change between sampled moments is | Anthropic: Claude Fable 5.1: Model B delivers the full arc requested: golden…
Subject action
A barista's hands pouring latte art: the milk stream forms a clean rosetta in the crema with natural, fluid wrist motion, no cuts, overhead close-up, soft café light, 16:9.
OpenAI: GPT-6 Luna: Model A maintains a steady overhead close-up and a continuous pour that develops into a clean, symmetrical rosetta-like design. Model B shows a plausible pour, but the framing is less overhead and the latte art remains muddier and less clearly defined. (Second judge pass, order swapped — scores are the average of both: Model B shows a fluid pour that develops into a flower-like rosetta, though the design is less cleanly defined. Model A maintains a steady overhead close-up and forms a more symme | Anthropic: Claude Fable 5.1: Model A shows a true overhead close-up with a c…
