Higgsfield AI just launched 14-Day Unlimited Seedance, running as two connected weeks: 7 days of unlimited Seedance 2.0 at 4K quality, followed by an extra 7 days of unlimited access on any other Seedance model, including newly released ones. New users get a separate way in too, a 24-hour window of free generations on Seedance 2.0 at 4K to test the quality before committing to anything. Here's exactly what's included, what isn't, and how the two weeks connect.
How the 14 Days Actually Break Down
Days 1-7: Unlimited Seedance 2.0 at 4K. The first week is the anchor of the entire offer: unlimited generation on Seedance 2.0, at 4K quality, for a full 7 days. This is the period where the offer is at its simplest, one model, one quality tier, no switching decisions to make yet. It's also the period most people will spend actually producing work rather than evaluating options, since the model and quality tier are already fixed from the moment the offer starts.
Days 8-14: Unlimited access extends to any Seedance model. Once the first week ends, the offer doesn't stop, it rolls straight into an extra 7 days of unlimited access on any other Seedance model, including models released after you started the offer. That second detail is what makes this offer relevant well beyond just Seedance 2.0, since it's specifically built to carry you into whatever comes next, including the upcoming Seedance 2.5. The two weeks are connected by design rather than being two separate offers stitched together, so there's no gap or re-signup required between them.
What's Included
Resolution and duration both scale by plan tier and billing cycle, and the two weeks behave differently from each other since they cover genuinely different models with different underlying capabilities.
First 7 days, Seedance 2.0:
Resolution | Plus monthly | Other plans |
|---|---|---|
720p | 15 sec | 15 sec |
1080p | 8 sec | 15 sec |
4K | Not available | 8 sec |
Second 7 days, after the switch:
Model | Available plans |
|---|---|
Seedance 2.5 | Plus monthly, Max/Ultra monthly, Pro/Plus annual, Max/Ultra annual |
Seedance 2.0 Mini | Plus monthly, Max/Ultra monthly, Pro/Plus annual, Max/Ultra annual |
Seedance 2.0 Fast | Plus monthly, Max/Ultra monthly, Pro/Plus annual, Max/Ultra annual |
Resolution and duration parameters for the second week: to be determined.
Plus monthly is the one tier that skips 4K entirely in the first week, capping at 1080p for 8 seconds or 720p for 15 seconds instead, depending on which resolution is selected. Every plan above Plus monthly gets 4K at 8 seconds from day one, without needing to do anything extra to unlock it. Specific parameters for the second week, across all three model options, will be determined and shared.
On day 7, a banner appears letting you pick which model carries the second week, with Seedance 2.5 highlighted as the featured option rather than listed quietly alongside the other two. The choice is Seedance 2.5, Seedance 2.0 Mini, or Seedance 2.0 Fast, and only one of the three can be selected, not a mix running simultaneously. If the specific reason you want this offer is to test 2.5 as soon as it's available, selecting it directly on day 7 is what actually gets you there.
Each plan also comes with its own baseline unlimited models running alongside the Seedance offer, and these vary by tier. Plus includes 7-day unlimited access to Nano Banana 2 (2K) and Kling 3.0, but Nano Banana Pro isn't included at that tier. Ultra includes all three, Nano Banana 2 (2K), Kling 3.0, and Nano Banana Pro (2K), each with the same 7-day unlimited window.
Who This Is For
New users:
24-hour window of free generations to try the offer without committing to anything
5 generations on Seedance 2.0 at 4K, up to 8 seconds each, from the moment the window activates
Doesn't renew into a paid plan automatically once the 24 hours or the five generations run out.
A card is required, but only for verification.
Existing users:
Get the full 7-plus-7 structure through an upgrade, available to essentially everyone
One exception: anyone already on the maximum adjustable tier of Ultra, the maximum adjustable tier of Max, or on a Team plan has no higher tier left to upgrade into
For that specific group, the Unlimited Models Marketplace offers a direct purchase instead: 14 days of Seedance Unlimited at 4K, up to 8 seconds.
Built specifically for users already at the top of their plan ladder, not as a general alternative to upgrading for everyone else
What's Not Included
A few details are worth flagging directly rather than discovering by accident partway through the offer.
Plus monthly doesn't include 4K on Seedance 2.0 during the first week, only 1080p and 720p, so 4K needs at least the next plan tier up.
Unlimited access here is scoped to the Higgsfield website, not automation surfaces like MCP, CLI, Canvas, or Supercomputer, so those workflows still use standard credits.
Seedance 2.5 Is Coming Soon
Seedance 2.5, ByteDance's next flagship video model, is headed to Higgsfield. The upgrade list is substantial: native 4K output, clips running up to thirty seconds in one generation, and support for as many as 50 multimodal references at once, which is what keeps a face, a product, or a location locked in place across the entire shot rather than drifting partway through. Prompt adherence is up 20% from the previous version, meaning what you actually write into the prompt is closer to what comes out the other end. A new region-edit feature also ships with it: point at the part of the frame that needs fixing, describe the change, and only that section gets repainted instead of forcing a full regeneration. Video and audio now generate together in a single pass too, so footsteps, engine noise, and score land in sync with the picture rather than feeling stitched on afterward.
How This Fits Into Higgsfield's Other Unlimited Offers
This isn't the first unlimited promotion Higgsfield has run, and the pattern by now is a familiar one. A 30-day Seedance Unlimited add-on ran earlier this year on Enhanced Seedance 2.0 Fast and Seedance 2.0 Mini, giving paid access to unlimited generations without the two-week structure this current offer uses. A referral program let users earn up to 7 days of unlimited Seedance 2.0 by inviting friends who subscribed to a paid plan, tying access to sharing the platform rather than a straightforward upgrade or purchase. A broader Unlimited expansion brought higher resolutions and more models into standard plan benefits across the board, well beyond just Seedance specifically, covering image and audio models alongside video. And a separate MCP-specific promotion extended unlimited generation into Claude and ChatGPT directly, rather than keeping it limited to the web platform the way earlier offers were.
This 14-day offer fits that same rhythm of limited-time, model-specific promotions, but it's also doing something the earlier ones didn't quite do in the same way: directly setting up the transition into a new model release rather than simply extending access to what already exists on the platform. The two-week structure, one week on the current model, one week on whatever comes next, is itself a new pattern compared to the flat single-model offers that came before it.
