ByteDance Seedance 2.5: The 30-Second 4K AI Video Model That Accepts 50 Reference Inputs

Release Timeline and Availability

Seedance 2.5 will be available through ByteDance's consumer ecosystem:

• Dreamina (the primary AI creative app) — the model will be accessible inside Dreamina's "AI Video" tool with a "Seedance 2.5" mode selection .
• CapCut — the public launch is expected on CapCut as well, and users can export from Dreamina directly to CapCut for editing .
• Doubao — ByteDance's other AI assistant will also get the model .
• Volcano Engine API — enterprise and developer access via ByteDance's cloud platform .

As of late June 2026, Seedance 2.5 is not yet generally available to the public — only enterprise beta testers have access . Users can still use Seedance 2.0 on Dreamina in the meantime .

How Seedance 2.5 Stacks Up Against Competitors

Seedance 2.5 enters a rapidly shifting AI video landscape. Independent comparisons rank it as the current leader on native duration, reference control volume, and brand/style consistency .

vs. Kling 3.0 (Kuaishou): Kling 3.0 leads on raw resolution and has a free tier, but Seedance 2.5 beats it on native duration (30 seconds vs. shorter clips), number of reference inputs, and brand consistency .

vs. Veo 3.1 (Google DeepMind): Veo 3.1 has strong developer API access and integrated audio, but Seedance 2.5 offers significantly longer native clips — 30 seconds versus roughly 8 seconds — and far more multimodal references .

vs. Sora 2 (OpenAI): Sora 2 still excels at physics realism and stylization, but OpenAI has deprecated Sora and is shutting it down, making it a dead end for new production work .

vs. Runway Gen-4: Runway leads on temporal consistency and professional-grade motion control, but Seedance 2.5's native 30-second generation and 50-reference input capacity outstrip Runway's current capabilities in length and controllability .

Analyst take: Seedance 2.0 had already displaced Kling v3 on the Artificial Analysis leaderboard within 90 days of launch, and Seedance 2.5 extends that lead by pushing the evaluation axis from single-scene clip quality toward multi-shot narrative coherence .
