Gemini Omni 1.1 Flash and Wan3.0 win at opposite jobs. Omni 1.1 is Google's fast video tier built for visual control — extend a scene to 40 seconds, set the first and last frame, draft in 360p for pennies, and upscale to 4K.
Gemini Omni 1.1 Flash and Wan3.0 win at opposite jobs. Omni 1.1 is Google's fast video tier built for visual control — extend a scene to 40 seconds, set the first and last frame, draft in 360p for pennies, and upscale to 4K. Wan3.0 is Alibaba's document-native model: it turns a slide deck, PDF, or one-pager into a narrated ~30-second clip with multilingual voice. Pick Omni 1.1 for frame-level craft and high-res hero shots; pick Wan3.0 for document-to-video and built-in narration.
These two are the fast, cost-efficient tiers of two rival stacks — Google's Gemini Omni and Alibaba's Tongyi Wanxiang — and they optimize for genuinely different work. Gemini Omni 1.1 Flash, announced August 27, 2026, is about control over the picture: scene extension to a cumulative 40 seconds in 10-second steps, exact first- and last-frame steering, a 360p draft mode that renders previews at roughly a third of the 720p cost, and 4K upscaling for a crisp final. Wan3.0, fully launched August 24, 2026, is about inputs and audio: it accepts documents — PDFs, slide decks, spreadsheets, web pages — and returns a clip up to about 30 seconds with multilingual voice and facial expressions rendered in-model.
So the real question is what you are feeding in and what you need out. If you are directing a shot — iterating cheaply, locking transitions with a first and last frame, and delivering a 4K hero — Omni 1.1 is the more controllable, higher-resolution tool, and its 40-second scene edges Wan's 30. If you are turning a marketing deck or one-pager into a narrated explainer, Wan3.0 is the one that reads documents and speaks; Omni does neither. Both are hosted endpoints that hand you a file — Omni through the Gemini API and AI Studio, Wan through Alibaba Cloud's application-gated Model Studio — so neither captions, reframes, or publishes what it makes.
| If you... | Pick | Why |
|---|---|---|
| I need the longest single scene | Gemini Omni 1.1 Flash | Omni 1.1 extends a clip to a cumulative 40 seconds in 10-second steps, analyzing up to ten seconds of prior footage for consistency. Wan3.0 caps around 30 seconds. |
| I want to turn a slide deck, PDF, or one-pager into a narrated video | Wan3.0 | Document-to-video is Wan3.0's standout — it accepts PDFs, decks, spreadsheets, and web pages and renders multilingual voice in-clip. Omni 1.1 takes text, images, and short video references only; it does not read documents or generate narration. |
| I want frame-level control and cheap iteration before a final render | Gemini Omni 1.1 Flash | Omni 1.1 sets an exact first and last frame to steer transitions, and its 360p draft mode renders previews up to 60% faster at about a third of the 720p cost. Wan3.0 has no comparable draft-then-upscale loop. |
| I need the highest-resolution output | Gemini Omni 1.1 Flash | Omni 1.1 upscales to 4K (1080p and 4K are upscaled, not native). Wan3.0 reportedly tops out at 1080p. |
| I need built-in voice and spoken narration in the clip | Wan3.0 | Wan3.0 generates multilingual voice and facial expressions in-model, so a document becomes a narrated video in one pass. Omni 1.1 is tuned for visual control, not native audio generation. |
| I need captions, per-platform sizing, and scheduling on the clip | Kompozy | Both are raw model endpoints — no captions, no reframing, no publishing. Kompozy adds all three on top of either. |
| I need a week of on-brand posts, not one clip | Kompozy | Neither fans a clip into shorts, carousels, a blog, and a newsletter under one brand voice and face. Kompozy does. |

The tell here is that Omni 1.1 and Wan3.0 are good at opposite halves of a real content week — Omni for a controlled, high-res hero shot, Wan for a deck-to-explainer with narration — and a serious calendar wants both, plus everything neither model makes. Kompozy is the shared finishing and publishing layer that unifies them. Bring in a 4K Omni scene or a Wan document-to-video and Kompozy burns in branded, on-style captions (silent-autoplay feeds swallow uncaptioned video), reframes cleanly between vertical and landscape per destination, and composites either into a Clipped Short or a Marketing Short with b-roll or music. Then it generates the identity and formats no generator touches — a face-locked Persona Short and HeyGen avatar video that keep one presenter across clips, a brand-exact Carousel, quote graphics, a Blog Article, and an Email Newsletter, all governed by one Persona Brief. Autopilot reviews the set and schedules it across the eight social platforms plus blog and email. Generate the Omni shot and the Wan explainer wherever each wins this month; Kompozy makes them read as one brand and ships them on a calendar.
It depends on the job. Omni 1.1 Flash is better for visual control and resolution: a 40-second scene, exact first/last-frame steering, cheap 360p drafts, and 4K upscaling. Wan3.0 is better for document-to-video and built-in narration — it turns a PDF, slide deck, or one-pager into a ~30-second clip with multilingual voice, which Omni cannot do. Choose by whether you are directing a shot or converting a document.
Omni 1.1 Flash, narrowly. It extends a scene in 10-second increments to a cumulative 40 seconds, analyzing up to ten seconds of existing footage so the extension stays consistent. Wan3.0 generates clips up to about 30 seconds — roughly double the prior Wan generation, but still short of Omni's extended ceiling.
Only Wan3.0. It accepts documents — PDFs, slide decks, spreadsheets, and web pages — alongside text, images, audio, and video, and renders multilingual voice in the clip, so a one-pager becomes a narrated video. Gemini Omni 1.1 Flash takes text, images, and up to three seconds of reference video, not documents, and does not generate spoken narration.
Both meter per second of generated video rather than a flat subscription. Omni 1.1 runs roughly $0.03 at 360p, $0.10 at 720p, $0.15 at 1080p, and $0.30 at 4K via the Gemini API. Wan3.0 runs roughly $0.05, $0.10, and $0.20 per second at 480p, 720p, and 1080p on Alibaba Cloud Model Studio, so a 30-second 1080p clip is about $6. Confirm current rates with each provider.
No. Both are generation-only endpoints — Omni through the Gemini API and AI Studio, Wan through Alibaba Cloud Model Studio — and output a video file with no captions, per-platform sizing, scheduling, or other content formats. To caption, reframe, and publish either model's clip across platforms, and to fan it into carousels, a blog, and a newsletter, pair it with a content engine like Kompozy.
