Kling 3.0 vs Wan 3.0: what changes when you switch a request?

Kling 3.0 from Kuaishou and Wan 3.0 from Alibaba take the same request format on Makernice, but a request written for one often fails on the other. Kling 3.0 encodes the resolution in its three model ids and always adds audio; Wan 3.0 uses a resolution field, accepts reference images and can return a silent clip. This guide lists the fields to change in each direction, along with catalog limits and prices. It does not compare how the footage looks.

How do the Kling 3.0 variants line up against Wan 3.0?

Kling 3.0 splits its tiers into three model ids: Kling 3.0 Standard at 720p, Kling 3.0 Pro at 1080p and Kling 3.0 4K at 4k. Wan 3.0 is one model id with a resolution field and reference-to-video. The table compares every catalog field.

Model pages: Kling 3.0 Standard, Kling 3.0 Pro, Kling 3.0 4K and Wan 3.0.

What breaks when you move a Kling 3.0 request to Wan 3.0?

Moving a Kling 3.0 request to Wan 3.0 mostly means replacing the model id with wan-3.0 and adding a resolution value. Four details decide whether the request carries over:

• The model id: kling-3.0-standard maps to wan-3.0 with resolution 720p, and kling-3.0-pro maps to wan-3.0 with resolution 1080p. Kling 3.0 4K has no Wan 3.0 counterpart, since Wan stops at 1080p.
• Leaving resolution out on Wan 3.0 gives 720p, so a former Pro request without the field drops a tier.
• Text-to-video ratios 9:16, 16:9 and 1:1 all exist on Wan 3.0, so those requests carry over unchanged.
• Durations from 3 to 15 carry over. Audio stays on unless you add generate_audio set to false.

What changes when you move a Wan 3.0 request to Kling 3.0?

Moving a Wan 3.0 request to Kling 3.0 removes more fields than it adds. Five details need a change:

• Remove resolution and pick the variant instead; Kling 3.0 answers a resolution field with an error saying the model has a fixed resolution.
• Remove generate_audio, because every Kling 3.0 clip has sound.
• Reference-to-video requests have no Kling 3.0 destination; Kling 4.0 takes up to 10 references.
• Text-to-video ratios adaptive, 4:3 and 3:4 are rejected; use 9:16, 16:9 or 1:1.
• Durations of 2 seconds or above 15 are rejected, and prompts must fit in 2,500 characters.

Which makes shorter and longer clips, Kling 3.0 or Wan 3.0?

Wan 3.0 covers both ends: 2 seconds at the short end and 30 at the long end. Kling 3.0 Standard, Pro and 4K each accept 3 to 15 seconds. Both default to 5 seconds when duration is omitted.

Can Kling 3.0 or Wan 3.0 skip the soundtrack?

Wan 3.0 can and Kling 3.0 cannot. Wan 3.0 adds audio by default and leaves it out when generate_audio is false. All three Kling 3.0 variants return audio on every request, with no field to change that.

How much do Kling 3.0 and Wan 3.0 cost per tier?

On Makernice, Kling 3.0 Standard is $0.1209 per second and Wan 3.0 is $0.0789 per second at 720p, on price list v15 (November 12, 2026). The per-second rate is shared by every mode of a tier. The 15 s column is the longest clip Kling 3.0 accepts; Wan 3.0 runs to 30 s at the same per-second rate.

Clip price = per-second price × seconds, rounded to the cent; the quote shows the exact amount. Kling 3.0 Pro vs Standard vs 4K explains the three Kling tiers in more depth.

Which should I choose, Kling 3.0 or Wan 3.0?

Let the request decide, because no side-by-side quality test of the two is published here. Kling 3.0 fits text-to-video at 4k (through Kling 3.0 4K) or a request that already uses Kling model ids. Wan 3.0 fits clips over 15 seconds or as short as 2 seconds, a 480p draft tier, silent output and reference images.
