As of May 5, 2026, both Seedance 2.0 and Seedance 2.0 Fast are live on Teno. Both tiers support native audio-video generation, start+end-frame image-to-video, and the same prompt grammar, with Fast available for quick drafts and standard reserved for higher-confidence clips. Existing accounts get access today; no plan upgrade is required.
Key Takeaways
- Both tiers ship today. Seedance 2.0 Fast is available for quick drafts, while standard Seedance 2.0 is ready for higher-confidence clips.
- Native audio-video is the headline. ByteDance says Seedance 2.0 uses a unified audio-video architecture for 4-15 second output (ByteDance Seed, 2026).
- Fast costs 16 credits per 5s clip; standard costs 20. At 720p with audio on, that's 20% less than standard and about 23% less than Veo 3.1 at 26 credits, per Teno's May 2026 model catalog.
- This post covers availability and pricing. For prompt examples and the fast-vs-standard quality breakdown, use the Seedance 2.0 ad-creative guide.
This post is the launch summary: what shipped on Teno, what it costs, who should try Fast first, and when to keep a Veo or Sora workflow in place.
What's new in Seedance 2.0?
ByteDance announced Seedance 2.0 on February 12, 2026 with four input modalities: text, image, audio, and video (ByteDance Seed, 2026). On Teno today, the ad-team surface is simpler: prompt, start image, optional end image, duration from 4-15 seconds, aspect ratio, audio toggle, and seed.
The five launch-day capabilities that actually change ad-creative pipelines:
- Native audio-video joint generation. Sound and motion come out of one prompt instead of a TTS-then-align pipeline. That's the default for UGC-style or talking-head clips.
- Start+end-frame image-to-video. Anchor both the first and last frames; the model interpolates the motion between them. This is the shortest path to before/after, transformation, and product-reveal beats.
- Multimodal references under the hood. ByteDance documents up to 9 images, 3 video clips, and 3 audio clips as model references; Teno exposes the smaller set ad teams use most often (arXiv:2604.14148, 2026).
- Multilingual audio out of the box. German, French, Japanese, and Spanish UGC variants render audio natively, which removes two hand-offs in cross-border creative pipelines.
- Two tiers, one model family. Standard and Fast share weights and controls; the difference is latency-and-price calibration, not a separately distilled smaller model.
How much does Seedance 2.0 cost on Teno?
At 720p with audio on, standard Seedance 2.0 costs 20 credits per 5-second clip on Teno, while Seedance 2.0 Fast costs 16 credits for the same output. That makes Fast 20% cheaper than standard, and standard about 23% cheaper than Veo 3.1 at 26 credits per 5-second 720p clip with audio on, based on Teno's May 2026 model catalog.
The math at 720p, by clip length:
| Tier | 5s | 8s | 12s |
|---|---|---|---|
| Seedance 2.0 | 20 credits | 32 credits | 48 credits |
| Seedance 2.0 Fast | 16 credits | 26 credits | 39 credits |
| Veo 3.1 | 26 credits | 41 credits | 62 credits |
For paid users, longer durations and 1080p output follow Teno's normal model credit schedule. Live credit-to-USD conversion depends on your active plan; see pricing for the exact rate.
When should you reach for Seedance 2.0 over Veo 3.1 or Sora 2 Pro?
For weekly ad testing, Seedance 2.0 should be the default when you need synchronized sound, dual-frame control, or cheaper per-variant billing in the same batch. In our early May 2026 tests, we storyboarded 50 ad concepts across 14 product categories (apparel, skincare, home cleaning, supplements, and 10 others). Roughly 38% (19 of 50) mapped cleanly to a bookend-frame Seedance 2.0 generation with setup under five minutes per variant. We counted a concept as a match when both frames could be sourced from existing stills and the motion beat was a single transformation, not a multi-scene narrative.
So when should you keep the older workflow? Use this launch-day map.
When Seedance 2.0 wins
- UGC and founder-cam. Default to Seedance 2.0 with audio on. Fewer pipeline stitches, lower cost per variant.
- Product reveals and transformations. Seedance 2.0 with start+end frames. Veo 3.1's I2V doesn't expose end-frame anchoring; Sora 2 Pro's doesn't either.
When to keep Veo 3.1 or Sora 2 Pro
- Photoreal stills-into-motion hero shot. Sora 2 Pro still wins when the seed is a polished still and the prompt is camera moves only.
- Long establishing shots (10-15s slow pulls). Kling O3 Pro is still the right pick on cinematic pull-backs.
- Talking-head ads where lip precision is the headline metric. Veo 3.1 keeps a narrow edge on tight single-shot sync; independent benchmarks scored it 9/10 on raw generation speed while Seedance 2.0 led on motion stability (The AI Journal, 2026).

Frequently asked questions
When did Seedance 2.0 go live on Teno?
Standard Seedance 2.0 and Seedance 2.0 Fast went live on Teno on May 5, 2026, alongside the existing Veo 3.1, Sora 2 Pro, and Kling O3 Pro options. Both tiers ship today across image-to-video and text-to-video workflows on every paid plan, with Fast also available on the free tier.
Do existing Teno users need to upgrade their plan to use Seedance 2.0?
No. Seedance 2.0 Fast is included on the free tier for short clips, and standard Seedance 2.0 is available on every paid plan from launch day. Credit cost is 16 credits per 5-second 720p clip on Fast and 20 credits on standard; the credit-to-USD rate follows your active plan.
Which Teno tools support Seedance 2.0 today?
Asset Generator lists Seedance 2.0 and Seedance 2.0 Fast in the model dropdown for text-to-video and image-to-video. URL-to-Video and other flows that render motion use the same catalog where that step applies. Audio toggle, duration (4-15s), aspect ratio, optional end-frame, and seed controls are supported on both tiers from day one.
Should I switch my existing Veo 3.1 ad workflows to Seedance 2.0?
It depends on the job. For native-audio UGC, product reveals using start+end frames, and weekly variant testing, Seedance 2.0 wins on credit cost and pipeline simplicity. For tight talking-head ads where lip-sync precision is the headline metric, Veo 3.1 is still our pick.
How do you use Seedance 2.0 on Teno today?
As of the May 5 launch, Seedance 2.0 is in Asset Generator with duration from 4-15 seconds, aspect-ratio controls, optional audio, and optional end-frame input. Open the studio, pick Seedance 2.0 or Seedance 2.0 Fast from the model dropdown, then write a prompt or attach a start image for image-to-video.
If your pipeline starts from still frames, create the start and end images in your image flow of choice (for example Product Photo or Asset Generator if you need GPT Image 2), then run bookend-frame image-to-video with both frames in Asset Generator.
Want the fastest test? Start a Teno account; Fast is available without a credit card.
