Quick verdict
Depends. The public data decides no category outright here. Vidu Q3 makes the slightly longer take (16 s[1] against 15 s[4]) and edges ahead on LMArena image-to-video — 1363[7] to 1354[8], a gap inside the confidence intervals. Kling 3.0 answers with native 4K[9] against Vidu's 1080p[3] ceiling, and with something Vidu does not offer at all: numeric prices you can actually read before you buy[5].

Summary
ShengShu's Vidu Q3 reached the Vidu Open Platform API on 2026-01-27[10]; Kling AI announced Kling 3.0 on 2026-02-05[11]. Feature-for-feature they are unusually close: both generate native audio, both handle text-to-video, image-to-video, start-and-end frame control and multi-shot output[3][4], and both sell through a consumer app plus a public API.
The spec differences are small but real. Vidu Q3 generates up to 16 s[1] per take against 15 s[4], and its reference-to-video endpoint accepts 1 to 7 images[2], where Kling publishes no reference-input maximum at all. Kling's edge is upward: a native 4K mode added in April 2026[9] against Vidu Q3's documented ceiling of 1080p[3], plus lip-synced audio[12] and in-video editing[11], neither of which appears in Vidu's Q3 documentation.
Transparency splits them hardest. Kling publishes a full USD rate card — from $0.126/s[5] at 720p with audio to $0.42/s[5] for 4K — and plan prices from $8.80/mo[13][13]. Vidu's pricing pages load their numbers with JavaScript our fetchers cannot read, so no numeric Vidu price appears on any official page we could verify; its API confirms only credit-based billing with discounted off-peak generation[3] and free monthly credits of an unstated amount[14]. On LMArena image-to-video, vidu-q3-pro scores 1363[7] (ranked #18[7]) to kling-v3-pro's 1354[8] (ranked #19[8]) — a statistical tie.

How rows are judged: a lower price, a longer clip, a higher resolution or frame rate, more reference inputs and a supported feature win. Prices of a discontinued product are shown as historical and cannot win. LMArena scores are human-preference ratings (board snapshot dated 2026-09-21, read 2026-10-07); scores whose ± intervals overlap count as a tie. VGI-Bench is a research benchmark of visual reasoning. A row marked — has no comparable data.
Where each model leads
Where Vidu Q3 leads
Length, references and baked-in audio. Takes of up to 16 s with dialogue, voiceover, sound effects and music generated in the clip[1], up to 7 reference images in one generation[2], and off-peak API discounts for non-urgent jobs[3]. The catch is that you cannot price a project from Vidu's public pages; for published numbers, AIContentDrop's credit price list shows per-model rates up front.
Where Kling 3.0 leads
Resolution and a readable rate card. Native 4K at $0.42/s[5][5], lip-synced native audio[12], in-video editing[11] and plans that renew from $8.80/mo[13][13]. To get repeatable motion out of it, our motion-JSON prompting notes for Kling 3.0 cover the structure that works.
Which should you choose?
Frequently asked questions
Is Vidu Q3 or Kling 3.0 better?
The public data calls it a draw. Vidu Q3 takes the longer clip (16 s[1] against 15 s[4]) and a nose-ahead LMArena image-to-video score inside the confidence interval; Kling 3.0 takes resolution with native 4K[9]. Choose by which of those your work actually needs.
What does Vidu Q3 cost?
There is no public number. Vidu's platform and consumer pricing pages render their figures in JavaScript that our fetchers cannot read, so the only official statements are credit-based billing with off-peak discounts[3] and free monthly credits of an unstated amount[14]. Kling, by contrast, lists $0.126/s[5] at 720p with audio on its developer rate card.
Which ranks higher on LMArena?
On image-to-video, vidu-q3-pro scores 1363[7] (ranked #18[7]) and kling-v3-pro scores 1354[8] (ranked #19[8]) — the confidence intervals make that a statistical tie. Neither Vidu Q3 nor Kling 3.0 appears on the text-to-video board; Kling 3.0 additionally scores 44.0[17] on VGI-Bench, where Vidu is absent.
