Seedance 1.0: history, status and what to use instead

What was Seedance 1.0?

Seedance 1.0 was ByteDance Seed's first publicly named Seedance video generation model. It established the family's approach: prompt-driven and image-driven short clips with a focus on motion quality and prompt adherence, served through ByteDance's own products and partner platforms rather than as downloadable weights. It predates the features people now associate with Seedance, such as native audio generation, multi-image and video referencing, and 30-second one-take generation, all of which arrived with the 1.5 and 2.x releases.

We deliberately keep the description of 1.0 short. ByteDance's current official pages are dedicated to 2.0 and 2.5, and we do not want to reconstruct a spec sheet for a superseded version from secondary sources and present it as verified. The release timeline guide records what is documented with dates and links, and is updated when ByteDance publishes anything new about earlier versions.

How the Seedance line evolved

The practical consequence: if you used Seedance 1.0 for short text-to-video or single-image animation, Seedance 1.5 Pro is the closest active model and adds native audio, 1080p and a fixed-lens option. If you want the current best quality, Seedance 2.0 gives up to 4K for 4–15 seconds and Seedance 2.5 gives 30-second reference-driven generation with editing.

Try the closest current model

The generator is preset to Seedance 1.5 Pro. Switch to 2.0 or 2.5 from the model picker; every option and the credit estimate come from the live model registry. Configuring is free; generating needs a subscription. Seedance 1.5 Pro is on both the Starter and Pro plans, while 2.0 and 2.5 are on Pro.

Current models compared

Mapping Seedance 1.0 use cases to today's models

• Short prompt-only clips: Seedance 2.0 Mini for drafts, Seedance 2.0 for delivery quality.
• Animating a single image: Seedance 1.5 Pro or 2.0 image-to-video with a first frame; add a last frame if you know where the shot should end.
• Locked-camera product shots: Seedance 1.5 Pro with fixed lens.
• Anything with sound: every active model generates native audio; 1.0 did not.
• Consistent characters across shots: Seedance 2.5 with reference images, which 1.0 could not do.

Example prompts in the 1.0 spirit, on current models

A red kite rises over a windy hillside at dusk, its tail whipping, the string taut against a lavender sky, a small figure below holding the reel. Wide shot, gentle handheld. Sound: wind and the flutter of fabric.

Starting from the uploaded still of a lighthouse on a cliff, bring it to life: waves roll in and break against the rocks, the beam sweeps once across the frame, clouds drift slowly. Camera locked. Sound: surf and wind.

Open source, downloads and access

As far as we can verify, ByteDance has not publicly released weights or code for Seedance 1.0 or any later version. There is nothing to download and run locally, and files claiming to be Seedance weights should be treated with suspicion. Access is through ByteDance's own products and hosted APIs; on Seedancee that means the active models above, paid per generation with credits from a Starter or Pro subscription. There are no free trial credits.
