Which to use
Start with Lite. At $0.03 a second at 720p against 1.5's $0.14 (read 22 October and 9 September 2026), our nine clips cost $1.36 against $6.30, and they came back sooner, 21 to 41 seconds against 36 to 49. On our prompts the two behave alike, good and bad. Both spelled the title card, Lite without the stray 'MME' that 1.5 flashed on its first frame; both made a steady harbour and a busy market with a busker and a dog. Both burned the line 'Good morning, the coffee is ready.' into the speaking woman's clip as a subtitle, and both gave the turntable dripper a mug handle. In image-to-video 1.5 reduced the pour to a few drops, while Lite poured coffee in and filled the dripper like a cup. Keep 1.5 for its reference and extend endpoints on fal. One run per prompt is a first look, not a ranking.

One try each, nothing re-rolled or retouched, generated by us. Grok Imagine Video 1.5 Lite is on the left, Grok Imagine Video 1.5 on the right. Every prompt has its own page with the whole roster.
Product turntable
Every model on this prompt →›What we asked for
A matte black ceramic pour-over coffee dripper rotating slowly on a white turntable, soft studio light, seamless white background, product video, no text.
Person speaking
Every model on this prompt →Both burned the spoken line into the frame as a subtitle, unasked.
›What we asked for
A woman in her 40s with short grey hair stands in a bright kitchen, looks at the camera and says 'Good morning, the coffee is ready', natural window light, handheld feel, she smiles at the end.
Animated title card
Every model on this prompt →Both spelled both lines. 1.5 showed stray letters 'MME' on its first frame; Lite was clean from the start.
›What we asked for
A title card reading 'MODA SUMMER SESSIONS' animates in over slow-motion footage of a festival crowd at dusk, then a smaller line 'Friday 12 June' fades in beneath it. Bold condensed type, tangerine on navy.
Camera move
Every model on this prompt →›What we asked for
Drone shot pushing slowly forward over a coastal town at sunrise, terracotta roofs, fishing boats in the harbour, long shadows, cinematic and steady.
Physics
Every model on this prompt →Lite's glass tips and the water pools, but it ends with four ice cubes where the prompt asked for three.
›What we asked for
A glass of water tips over on a wooden table and spills in slow motion, water and three ice cubes sliding across the wood, macro lens, morning light.
Hands at work
Every model on this prompt →›What we asked for
Close-up of hands pouring hot water from a gooseneck kettle in slow circles into a pour-over coffee dripper, steam rising, shallow depth of field, warm cafe light.
Busy scene
Every model on this prompt →›What we asked for
A crowded Saturday farmers market seen from slightly above, shoppers with tote bags, a dog on a leash, a busker with a guitar, bunting swaying, late morning light, gentle camera drift.
Specific art style
Every model on this prompt →›What we asked for
A lighthouse on a rocky cliff in a storm, in the style of a Japanese ukiyo-e woodblock print, waves crashing in flat colour with visible wood grain, animated like moving paper cutouts.
Image to video
Every model on this prompt →Both kept the photographed dripper. 1.5's pour became a few falling drops; Lite filled it like a cup.
›What we asked for
The coffee dripper slowly fills as coffee drips through it, steam rising, the camera drifting gently around it, the dripper itself unchanged.
Frequently asked questions
How much cheaper is Grok Imagine Video 1.5 Lite?
On fal at 720p, $0.03 a second against $0.14, about a fifth. Our nine five-second clips cost $1.36 on Lite and $6.30 on 1.5.
Is Lite worse?
Not on our nine prompts. It made the same mistakes as 1.5, including the burned-in subtitle, and a cleaner title card. One run per prompt cannot rule out differences elsewhere.
