Quick verdict
Pick Kling 3.0 for most projects: it generates audio together with the picture while Ray3.2 outputs silent clips[2], its resolution ceiling is 2160p (4K)[3] against 1080p[2], and its cheapest paid plan renews at $8.80/mo[6] against $30.00/mo[7] for Luma's Plus tier. Pick Ray3.2 when delivery format decides: it is the only one of the pair with a 60 fps[2] mode, HDR and EXR output at published surcharges[8], and clips of up to 20 s[1] at 24fps[2].

Summary
Luma AI released Ray3.2 on 2026-06-09[1] and opened it to developers as an API for the first time[1]. Kling AI had announced Kling 3.0 months earlier, on 2026-02-05 (announcement date)[9], and added a native 4K mode on 2026-04-23[10]. Both are available today: Ray3.2 through the Luma app and API[2], Kling 3.0 through credit memberships and a prepaid developer API[4].
The two aim at different jobs. Ray3.2 is built around motion and finishing control: a frame-rate ladder of 24, 30 or 60fps[2], up to 16 keyframes inside a single clip[2], camera-move transfer between scenes, facial performance transfer for up to 8 faces[2], and a Modify Video mode that reworks footage you already have. What it does not do is sound: Luma's own FAQ states there is no natively generated audio in text-to-video or image-to-video output[2]. Kling 3.0 generates dialogue, ambience and effects with matching lip movement[11], builds multi-shot scenes in one generation[3], and renders 2160p (4K)[3] natively.
Billing is hard to compare line by line. Luma's API charges per video in 5-second blocks: a 5-second 1080p text-to-video clip costs $1.20[8], and HDR output doubles the SDR price[8]. Kling prices per second, from $0.126/s[4] at 720p with audio to $0.42/s[4] for 4K. On public leaderboards the two never meet: kling-v3-pro scores 1354[12] on LMArena's image-to-video board, but we found no Ray3.2 entry on either LMArena board, so there is no like-for-like ranking. To judge output quality yourself, you can run the same prompt on AIContentDrop and set the Kling 3.0 renders beside your Luma tests.

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 Luma Ray3.2 leads
Frame rates and finishing. Ray3.2 renders at 24fps up to 20 s[1], at 30fps up to 15 seconds and at 60fps up to 7 seconds[2], across six aspect ratios[2]. HDR output costs twice the SDR rate and HDR with EXR frames three times[8], which targets grading pipelines rather than social feeds. Plans start with Plus at $30.00/mo[7] ($25 a month on yearly billing[7]) with 10,000 credits included[7]; Luma's pricing page shows no free tier[7].
Where Kling 3.0 leads
Audio, resolution and price of entry. Kling 3.0's Native Audio mode produces dialogue, ambience and effects synced to lip movement[11]; in the app, a second of 1080p with audio costs 12 credits and native 4K 30 credits[3]. The Standard plan renews at $8.80/mo[6] after a $6.99 first month[6], with 660 monthly credits[6]. If you script your shots, our guide to structuring Kling 3.0 motion prompts in JSON shows how to direct multi-shot scenes.
Which should you choose?
Frequently asked questions
Does Luma Ray3.2 generate audio?
No. Luma's Ray FAQ states that text-to-video and image-to-video output has no natively generated audio[2]. Kling 3.0 ships a Native Audio mode with dialogue, ambience, sound effects and lip movement[11].
Which is cheaper, Ray3.2 or Kling 3.0?
On monthly plans, Kling: Standard renews at $8.80/mo[6][6], while Luma's cheapest plan is Plus at $30.00/mo[7] ($25 a month billed yearly[7]). The APIs bill on different bases: Luma per video in 5-second blocks ($1.20 for a 5-second 1080p clip[8]), Kling per second from $0.126/s[4]. AIContentDrop's plan pricing is a third route, from $19/mo or $14/mo billed annually[14].
Which makes longer clips?
Ray3.2 reaches 20 s[1] at 24fps[2], though native text-to-video and image-to-video clips are 5 or 10 seconds[2]. Kling 3.0 generates up to 15 s[3] in one take and includes video extension from the Standard plan up[11], with no published maximum extended length.
