Wan 3.0 vs Wan 2.7: What Changes When You Upgrade?

Wan 3.0 raises the maximum duration from 15 to 30 seconds and broadens the supported output formats. It is not a half-price upgrade: matched 1080p pricing rises from $0.15/s on Wan 2.7 to $0.21/s on Wan 3.0. A five-second t2v estimate rises from $0.75 to $1.05.

Current Ofox rates by resolution

All amounts are USD per second. Wan rows show public list prices; the primary supplier quotes match them in this snapshot: alicloud for Wan 3.0, aliyun for Prime and Wan 2.7/2.6. These are dated quotes, not a promise that prices will remain unchanged.

Price check: 2026-09-16. Five-second amounts estimate t2v with no input video; v2v totals require the input-video duration.

Estimating a five-second clip

Examples assume text-to-video (t2v), 5 seconds of output and no input video. They are estimates from public rates, not measured invoices. For requests with video inputs, include applicable input-video seconds and use the matching input-mode rate. Do not reuse the text-only total for a reference-video job; check final charges against the completed task.

Choosing a model after the price correction

At 1080p, Wan 3.0 is 40% more expensive per second than Wan 2.7/2.6 ($0.21 versus $0.15). At 720p it is about 27.9% more expensive ($0.11 versus $0.086). Choose the newer model for capabilities your workflow needs and validate output quality; upgrading is not automatically a cost saving. Prime costs about 23.8% more than standard at 1080p ($0.26 versus $0.21); the premium differs by resolution. Its catalog description positions it for speed, but does not supply a measured latency guarantee.

Recalculate budget alerts by resolution and expected billable duration. At 1080p, 100 five-second t2v clips are estimated at $105 on Wan 3.0 versus $75 on Wan 2.7; 1,000 clips are $1,050 versus $750. These examples contain no input-video seconds and do not include retries or assume negotiated discounts. Retain Wan 2.7 when its output meets your needs and its lower matched-resolution rate matters more than the newer capabilities.

Wan 3.0 vs Wan 2.7: What Actually Changed

The 15-Second Wall Is Gone

Wan 2.7 stops at 15 seconds. Wan 3.0 goes to 30. For anything longer than 15 seconds on 2.7, the workaround was to generate in segments and stitch, which costs you continuity at every seam and engineering time around the joins.

Wan 3.0 also handles continuation directly, and the rule there is worth reading before you plan around it: when you pass input video, the input duration plus the output duration together cannot exceed 30 seconds, per Alibaba’s Wan 3.0 API reference. So 30 seconds is a total budget, not a per-call output allowance on top of whatever you feed it.

One Model Instead of a Model per Task

This is the structural change, and it is easy to miss because it does not appear in a price table. On Alibaba Cloud, Wan 2.7 exposes tasks through separate model strings and reference pages: wan2.7-t2v for text-to-video, with first-frame, first-and-last-frame and continuation documented separately. Wan 3.0 collapses that into wan3.0-video, taking text, images, video and audio mixed in one request, and covering text-to-video, image-to-video, reference-to-video, editing and continuation.

Through Ofox the difference is smaller than it sounds, because both models already sit on /v1/videos with the same parameter set and the mode follows from your inputs: frame_images selects first-frame or first-and-last-frame, input_references selects reference-to-video. What changes is that on 3.0 the same behaviour is native to a single upstream model rather than a gateway smoothing over several.

The Migration Is One String

- "model": "alibaba/wan-2.7"
+ "model": "alibaba/wan-3.0"

Keep the request structure, but recheck the settings and output quality before switching production traffic. Both models accept prompt, duration, resolution, aspect_ratio, size, generate_audio, seed, frame_images, input_references, callback_url and provider, and both default to 1080p and to audio on.

Re-check these settings after the swap:

• Aspect ratio. Wan 2.7 supports 16:9, 9:16 and 1:1, and rejects anything else with aspect_ratio "4:3" not supported; allowed: [16:9 9:16 1:1]. Wan 3.0 supports those plus 4:3, 3:4 and adaptive, and adaptive is the default. Anything that relied on an unset aspect ratio behaving a particular way should now pin it explicitly. The Wan 3.0 error reference has the full rejection set for both models.
• Duration assumptions. Code that clamps user input to 15 seconds because 2.7 required it is now leaving half the range unused. Code that assumed a 15-second maximum for cost estimation will under-estimate a 30-second clip by exactly 2x.

Source and billing boundaries

Prices were checked on 16 September 2026 against the public Ofox catalog and the linked model pages. Compare the same resolution, input mode and audio settings, and distinguish public list prices from provider-specific quotes. Estimates assume the stated output length and no input video unless explicitly indicated; video inputs can add billable seconds. These examples are not measured invoices, and final charges depend on the completed task and applicable provider rate. Recheck prices before budgeting production usage.
