Is it worth sacrificing content safety safeguards to achieve faster breakthroughs in AI technology development?
In April 2026, researchers at the University of Hong Kong identified ByteDance's Seedance 2.0 Pro as the leading AI video-generation model for visual quality. The evaluation compared 12 models using human assessments and Chinese-language prompts.
Why it matters
The study highlights how ByteDance leveraged its vast repository of short-form video training data to achieve high visual fidelity. However, the findings also reveal a notable gap in content filtering, as Chinese models often trailed their US counterparts in safety measures.
Seedance 2.0 Pro achieved a visual quality score of 3.84 out of 5, while MiniMax's Hailuo 2.3 led the group in safety with a 3.63 rating. Researchers assessed 11 models for safety and 12 for quality using 71 distinct prompts.
The players
ByteDance
A global technology company known for its short-form video platforms that provide extensive datasets for AI training.
University of Hong Kong
A public research university that conducted the comparative analysis of international AI video-generation models.
Google DeepMind
The AI research laboratory responsible for the development of the Veo video-generation model.
OpenAI
An artificial intelligence research organization that developed the Sora model before discontinuing it in April 2026.
MiniMax
An AI developer that produced the Hailuo model, which earned the highest safety rating in the study.
The details
The research utilized 20 human evaluators to score models based on 71 Chinese-language text-to-video and image-to-video prompts. While Seedance excelled in visual performance, it ranked only sixth out of 11 models in its ability to block harmful content.
Timeline
April 2026: University of Hong Kong researchers conducted the AI model assessment and OpenAI discontinued Sora.
May 2026: Google launched its Omni AI model.
July 2026: ByteDance launched the Seedance 2.5 model.
August 2026: Google released an Omni 1.1 Flash update.
October 2026: Kuaishou released Kling 4.0.
The Tech Race
This study benchmarks the performance of the Seedance 2.0 Pro AI video-generation model as the industry transitions toward high-fidelity generative video. It highlights the growing competition between Chinese and American AI labs to dominate video-generation capabilities.
Users can expect higher visual quality in generated media as companies like ByteDance integrate these models into their platforms. However, varying safety protocols mean consumers should remain aware of potential differences in content moderation policies across different AI tools.
The takeaway
The study demonstrates that visual quality is no longer the only metric for AI success as safety filtering becomes a primary concern for developers. Users should prioritize platforms that balance advanced creative features with robust content safety standards.
