Seedance 2.0

Model family: seedance

ByteDance's proprietary text-to-video model, known for highly realistic clips — and for drawing cease-and-desist letters from Disney and Paramount in Feb 2026 over alleged training on their works. Capable, but carries unresolved IP risk.

Listing Notes

Flagged for a significant IP concern: after Seedance 2.0's February 2026 launch, realistic clips replicating real actors, TV shows, and films went viral, and Disney and Paramount sent ByteDance cease-and-desist letters alleging the model was trained on their copyrighted works without compensation. ByteDance responded that it "respects intellectual property rights" and would strengthen safeguards; the dispute was unresolved as of this writing. Businesses considering commercial use should treat the training-data provenance as an open legal risk, separate from the product's usage terms.
