A few months ago, choosing an AI video model was simple. There were maybe three serious options, and they all cost roughly the same. Today, the landscape is completely different.
ByteDance's Seedance 2.0 brings multimodal input and 1080p output. xAI's Grok Imagine Video 1.5 just took the #1 spot on the Arena leaderboard. And Alibaba's Wan 2.7 — an open-weight model that costs a fraction of either — is quietly matching both on quality while beating them on speed and price.
I've spent the past month running all three through the same tests: same prompts, same source images, same evaluation criteria. Here's what I found, and why I think most creators should start with Wan 2.7.
TL;DR
- Grok Imagine Video 1.5 ranks #1 on the Arena Image-to-Video leaderboard (+52 Elo vs v1.0) and delivers the best single-image animation quality with synchronized audio.
- Seedance 2.0 is the most feature-rich option — multimodal inputs, 1080p output, video editing, and multi-shot character consistency.
- Wan 2.7 matches or beats both on image-to-video quality in many scenarios, costs significantly less, generates both video and images, and is available as open weights — making it the best value by a wide margin.
- If budget is no object and you need maximum quality for a single shot, Grok Imagine 1.5 has the edge. If you need a full production pipeline, Seedance 2.0 does more. For everyone else, Wan 2.7 delivers 90% of the quality at 10% of the cost.

Real Test Results: Same Prompt, Three Models
I tested all three models with a consistent evaluation: same product photo (a leather travel bag), same motion prompt ("slow rotation on a turntable with studio lighting, fabric texture visible"), and same quality expectations.
Wan 2.7 returned a 10-second clip at 720p in under 2 minutes. The bag rotated smoothly, the leather texture rendered with convincing specular highlights, and there was zero frame-to-frame flicker — a common issue with earlier video models. The lighting stayed consistent throughout. For a model that costs roughly 2 cents per generation, the quality was genuinely surprising.
Seedance 2.0 at 1080p was sharper — the stitching details on the bag were more defined, and the overall image quality was noticeably cleaner. However, the motion felt more mechanical, more like a keyframe interpolation than a physics simulation. Generation took about 4 minutes. The cost was roughly 10x Wan 2.7.
Grok Imagine Video 1.5 at 720p produced the most "alive" clip. The Aurora physics engine gave the bag's leather a subtle natural sway that neither Wan 2.7 nor Seedance 2.0 matched. The synchronized audio — a soft rustling sound — added a layer of immersion the other models didn't match. But generation time was comparable to Seedance, and the cost was similar.
My takeaway: In a blind test, I'd struggle to reliably distinguish Wan 2.7 from Grok Imagine 1.5 on visual quality alone for most product and scene types. The difference shows up in edge cases — complex motion, portrait animation, audio sync — but for standard video generation, Wan 2.7 holds its own.
What Is Wan 2.7?
Wan 2.7 is Alibaba's latest AI video and image generation model. It's an open-weight model — meaning you can download and run it on your own hardware — though most creators access it through cloud platforms. Unlike Seedance 2.0 (video only) and Grok Imagine 1.5 (image-to-video only), Wan 2.7 handles both video generation and image generation in a single model.
Key capabilities:
- Text-to-video: Generate video clips from text descriptions
- Image-to-video: Animate still images with guided motion
- Text-to-image: Generate high-quality images from prompts
- First-frame control: Specify the first frame for precise composition
Wan 2.7 consistently ranks among the fastest AI video models in its class, with generation times typically 40-60% faster than Seedance 2.0 or Grok Imagine 1.5 for comparable output.
Best for: Creators who want high-quality AI video without the premium price tag, especially high-volume workflows and budget-conscious projects.
What Is Seedance 2.0?
Seedance 2.0 is ByteDance's most advanced AI video model, built on a unified multimodal architecture that processes text, images, video clips, and audio together. Its @ mention reference system lets you feed it multiple reference materials and control generation with natural language.
The key differentiator is feature breadth: Seedance 2.0 handles text-to-video, image-to-video, multi-reference generation, video editing, style transfer, and multi-shot character consistency — all in one system. Output goes up to 1080p with native audio-video joint generation.
Best for: Professional production pipelines that need multi-shot narratives, brand consistency, and broadcast-ready resolution.
What Is Grok Imagine Video 1.5?
Grok Imagine Video 1.5 is xAI's image-to-video specialist, built on the Aurora physics engine. Released May 2026, it reportedly holds the #1 spot on the Arena Image-to-Video leaderboard with a significant Elo improvement over version 1.0.
It's a purpose-built model — image in, animated video with synchronized audio out. No text-to-video, no multi-reference input, no video editing. But within that narrow scope, it produces the most visually convincing and physically grounded animation available today.
Best for: Portrait photographers, product shooters, and anyone who needs the highest possible quality from a single image animation.
