Sora 2 vs. Grok Imagine Video 1.5

Compare the exact model versions across shared blind-preference benchmarks, public pricing, release dates, resolution, duration, native audio, access, and model availability.

Overview

Technical specifications and pricing

Technical limits come from model or API documentation. A representative minute price appears only when it can be traced to the exact model. Different resolutions and audio settings may still affect the final charge.

Key to the marks:better valuebetter, but not conclusivetie

Performance

Shared video benchmarks

A row appears only when both exact model versions occur in the same LMArena task and stored dataset revision. Text-to-video and image-to-video are never merged into one score.

No shared task in the stored data

Sora 2 and Grok Imagine Video 1.5 both have published LMArena data, but not in the same video task. Older versions and the other task are not used as substitutes.

Visual comparison

Sample videos

Only runs from both exact model versions under the same archived prompt and first-output rule appear here. Provider showcases and substitute versions remain excluded.

Controlled practical comparison. Both exact model versions received the same archived prompt in one request. The first output counts. Playback uses the first five seconds, 1280 × 720 pixels, 30 fps, no crop, and muted audio. Provider-side randomness and prompt processing remain model characteristics.

How to read the data

Preference is not the same as production fit

A higher LMArena rating means that outputs from this exact configuration were preferred more often in blind comparisons.

Motion control, identity consistency, audio, turnaround time, moderation, and licensing may matter more than the aggregate preference rating.

Prices are representative public minute rates, not a normalized cost benchmark.
