Summary
At $0.08 per second of video it is cheap; a typical video model costs $0.12.
Grok Imagine Video 1.5 is xAI’s generally available video model for the Imagine API. Text or a starting image can produce up to 1080p; compared with Grok Imagine Video, xAI reports better motion physics, more coherent movement, and clearer, better-synced speech.
Preset voices, sound effects, ambience, and dialogue are generated in the same pass as the images. Version 1.5 therefore joins image-to-video and sound in one short clip.

- Context
- Artificial Analysis describes Elo based on blind pairwise human-preference votes by validated private evaluators, but publishes no evaluator affiliations or evidence of institutional independence. The unit of the “Samples” column is undefined, so no sampleCount or per-cell N is inferred from it. This dated live-board snapshot does not identify an immutable serving revision and is not a separate test run by this project.

- Independent evaluation. Independent evaluation of the released Grok Imagine Video 1.5 API through its native Prompt-I2V interface on the same frozen set of 330 HarnessEval-W cases. Table 4 reports API access, 848×480 output, 49 frames per turn, and 24 FPS. The evaluator used the same VLM backend, temperature, and frame-sampling configuration across models; the specific settings are not stated. The paper reports this metric on its normalized 1-100 score scale. Table 2's first observation header is Obs-Q; section 5.1 uses Obs-R for Render Quality, so the exact mapping is not asserted.
- Context
- Table 2 labels the first observation column Obs-Q, while section 5.1 names Render Quality as Obs-R. The raw Table 2 label is preserved; equivalence is not assumed. The paper does not state a separate evaluation run date, immutable API revision, or confidence intervals. Scores are on its normalized 1-100 evaluator scale, not percentages.

Prompt and settings
Generate exactly one continuous five-second 16:9 cinematic video. A fictional bicycle courier in a mustard-yellow raincoat rides a red city bicycle from left to right across a rain-wet Hamburg street at blue hour for the entire clip. The camera tracks her smoothly at waist height. Both hands remain visible on the handlebars, the bicycle geometry stays physically correct, and a transparent umbrella fixed to the bicycle moves naturally in the wind. Wet-street reflections and raindrops follow realistic physics. No cuts, no slow motion, no text, no logos, no subtitles, and no audio.
