Limitations and availability
BytePlus reported that selected film production and post-production companies were trialling the model; that announcement does not establish general availability or a public API launch date. Its ModelArk pricing page lists the standard Seedance 2.5 API model only through 1080p, so that listing should not be treated as confirmation of API access to this 4K release. (byteplus.com)
Release date and official sources
- The supplied release date is October 23, 2026. The supplied BytePlus X announcement could not be directly read because access was denied, so its date could not be independently verified from the post.
- The directly readable BytePlus official announcement is dated October 27, 2026. (byteplus.com)
