Direct answer
Do not compare subscription labels alone. Calculate the cost for the same version, duration, resolution, audio and reference inputs, then include failed retries and unused subscription credits.
This article answers the search question “undefined”. The source report ranks this question #32 with a 28-day volume of 1.1K. That metric describes observed search demand, not product quality, price or availability.
What the evidence supports
- ByteDance Seedance 2.5 announcement: Seedance 2.5 was announced July 31, 2026 with up to 30-second generation, more reference inputs, multi-round extension and timestamp editing; availability can differ by platform.
- BytePlus ModelArk pricing documentation: BytePlus documents usage-based API billing affected by duration, resolution and video input. Its current calculator or returned usage is more reliable than a copied price.
What to do
Do not compare subscription labels alone. Calculate the cost for the same version, duration, resolution, audio and reference inputs, then include failed retries and unused subscription credits.
A model announcement, a provider listing and access in your own account are separate facts. Use the live account and pre-generation quote as the operational evidence.
What to verify
- Confirm the exact model name and version in the live selector.
- Set duration, resolution and reference inputs before comparing access or cost.
- Save the displayed quote, job ID and settings so the result can be reproduced.
- Recheck the provider page if an offer, region or plan changes.
Open the yeha.ai video workspace and confirm the exact model, settings and displayed credit quote before submitting.
What to avoid
Do not copy a price, free quota, resolution or availability claim without its date and provider context. Search volume is not evidence that a claim is true.
