AI Video Model Comparison: WAN 2.7, Veo 3.1 & Grok Imagine 1.5

Описание: In this video, I compare three of the latest AI video generation models—WAN 2.7, Veo 3.1, and Grok Imagine 1.5—using the same collection of celebrity-inspired prompts. Each prompt features humorous, cinematic scenarios alongside my recurring character, Desert Robert, allowing for a direct comparison of how each model handles realism, creativity, dialogue, facial consistency and prompt accuracy.

Models Tested:

✅ WAN 2.7

WAN 2.7 was easily the most creative model of the three. It frequently expanded upon the original prompt with additional visual ideas and often generated dialogue when prompted appropriately. The videos also tended to include more cinematic close-up shots, making the characters feel expressive and engaging.

However, this creativity came with a few trade-offs. Facial consistency could vary throughout a clip and some characters gradually became blurred or lost detail as the video progressed. Another observation was that many characters spoke with a very similar voice and delivery style, regardless of who they were portraying.

✅ Veo 3.1

Veo 3.1 produced consistently high-quality videos and was the most accurate at following the original prompt. The scenes generally matched the requested actions, camera angles and environments more faithfully than the other models.

The voice generation was also noticeably more diverse, with speech patterns and delivery feeling better aligned to the celebrity-inspired characters. Facial consistency was stronger than WAN 2.7, although there is still room for improvement during longer sequences.

✅ Grok Imagine 1.5

Grok Imagine 1.5 delivered some of the most visually impressive results in the comparison. Character models contained excellent detail and facial consistency remained strong throughout most clips, resulting in believable and stable performances.

Although it wasn't quite as creatively adventurous as WAN 2.7, it still introduced interesting visual flourishes while remaining faithful to the prompt. One of its standout strengths was voice generation, with each character sounding noticeably distinct and fitting their individual personalities much better than the other models.

My Overall Thoughts

Each model excels in different areas:

• WAN 2.7 – Outstanding creativity, cinematic close-ups and prompt expansion, but weaker facial consistency and similar-sounding voices.

• Veo 3.1 – Excellent prompt adherence, balanced quality, improved facial consistency and more natural voice diversity.

• Grok Imagine 1.5 – Outstanding visual quality, highly detailed characters, excellent facial consistency, distinct voices and an impressive overall experience.

No single model is perfect, but each brings unique strengths depending on whether you value creativity, prompt accuracy, or visual fidelity.
