Flux 3 vs WAN 3.0: the input decides the model

Flux 3 vs WAN 3.0 is settled by the raw material sitting on your desk, not by which model wins a spec sheet. Flux 3 takes words, stills and clips, and it lets you nail specific images to specific moments inside a shot. WAN 3.0 takes all of that and adds two things Flux 3 does not read at all: a document and a live web page.

Flux 3 comes from Black Forest Labs and generates up to 20 seconds of video with its soundtrack built in the same pass. WAN 3.0 is Alibaba’s latest WAN release and runs a single continuous take to 30 seconds. One of them is in Picsart right now and the other is not, which is covered at the end and matters more than any row in the table.

What follows works through four starting points: a file, a set of stills, a clip you already have, and one bare sentence. Two of them point at a single model. Two are closer than the marketing suggests.

Start from a PDF, a deck, or a product page

WAN 3.0 reads documents as reference material. Upload a .doc, .pdf, .ppt or .xls and the model works from what it finds inside. Hand it a web page URL instead and it treats that page as the source: a product listing, a news piece, a research paper, a marketing site.

Flux 3 has no equivalent. Its inputs are a prompt, images and a clip, so moving a spec sheet into a Flux 3 video means reading the sheet yourself and rewriting it as a prompt.

That gap decides a specific kind of work: anything that begins with a document nobody wants to summarize twice. A product page turns into an ad film. A quarterly deck turns into a recap. A spec sheet turns into a feature walkthrough. The source material stays the source material and the model handles the translation, which removes the step where a person reinterprets the document into prompt language and quietly loses half of it.

Start from stills that have to land on cue

Flux 3 accepts up to ten images pinned to timestamps, and the finished clip travels through them in order. A single image sets the first frame. Two images fix both ends and the model builds the movement between them. Ten spread across the timeline become a storyboard the shot is obliged to hit.

WAN 3.0 works from the ends. It works from an opening frame plus a closing one, then holds reference detail steady across everything between them, keeping characters, objects, scenes and styles pixel-consistent through the sequence.

Read that as choreography against continuity. Flux 3 answers the question of what happens at second three and again at second seven. WAN 3.0 answers the question of whether the person who walked in at the start is recognisably the same person at the end. Product reveals timed to a music cue, dance beats and title cards landing on an action all want the first. A long take carrying a cast that cannot drift wants the second.

Start from a clip you already have

Both models carry existing footage forward, which makes this the input where the two come closest.

Flux 3 continues a clip you supply. It picks up from the final frames and keeps momentum, framing and scene logic running without a visible cut, and continuations run five to fifteen seconds. WAN 3.0 extends a generated clip further, so a 30-second take becomes a base to build on rather than a ceiling to work under.

The useful question is how long the finished thing needs to be and where the first piece came from. Sequences assembled entirely inside one model favor WAN 3.0, which starts from a longer base. Footage that arrived from somewhere else goes to Flux 3, which is built to take a clip and keep going.

Start from one sentence

Both models fill in the gaps around a bare prompt, and both choose the clip length for you unless told otherwise. WAN 3.0 does it through smart duration, reading the action and pacing described and suggesting a length that fits. Flux 3 defaults duration and aspect ratio to auto and sizes them to the content, with anything from five to twenty seconds available on request.

The emphasis diverges after that. WAN 3.0 puts its weight on instruction following, parsing detailed multi-part briefs and honoring them in the output. Flux 3 puts its weight on cheap exploration: a draft render returns a fast preview, and sending that draft back renders the same generation at full quality instead of a fresh interpretation of the words.

Those solve different anxieties. One is about a long, precise brief surviving the first pass intact. The other is about not losing the version you liked when you go to finish it.

On-screen text is where they collide

Both models advertise readable text, which is rare enough that it deserves testing rather than trust.

Flux 3 builds lettering into the shot itself, placed where it belongs and readable, and keeps it from warping while the camera and subject move. Title cards, shop signs and lower-thirds all hold. WAN 3.0 claims stronger text rendering specifically for information-heavy content, alongside image detail closer to real footage in dense scenes. Its emphasis sits on frames carrying a lot at once rather than on a single clean title.

Neither claim cancels the other, and read together they point at different jobs. A title holding steady over motion leans Flux 3. A frame crowded with labels, figures and signage leans WAN 3.0. This is the row worth resolving with a test on your own copy rather than by reading either page.

What you can use today

Flux 3 is live in Picsart, in three places. AI Playground sends a single prompt out to a whole shelf of models, so judging one against another takes a minute rather than an afternoon. The AI video generator handles it as a standalone job. Flow chains it into multi-step pipelines.

WAN 3.0 is not in Picsart yet. Everything above describes what the model does rather than something you can open and run this afternoon, so work shipping this month goes to Flux 3 by default and the comparison turns practical the day WAN 3.0 arrives.

There is still something worth doing before then. Pull together the documents and product pages that could seed a video, because that is the input WAN 3.0 adds and the one that needs no prompt writing at all. A folder of decks and live URLs is a running start on day one.
