Seaweed AI is a lightweight AI video generation model developed by ByteDance. It's designed to create high-quality videos in a wide range of styles—from realistic short clips to cinematic visuals—all with rich detail and impressive clarity.
What truly makes it stand out is its powerful Diffusion Transformer model, equipped with around 7 billion parameters and trained using computing power equivalent to 1,000 H100 GPUs. It learns from massive amounts of text, images, and videos to understand the world and generate lifelike motion, natural expressions, and emotional realism. The Seaweed AI video model allows users to produce videos of various resolutions, lengths, and aspect ratios based on their input prompts. Here's a quick look at its main features:

Seaweed AI Image to Video: Turn an image into a dynamic video by using it as a reference or first frame.
Realistic Short Clips: Create highly detailed and dynamic scenes with realistic human movements, gestures, and even lip-syncing.
Given this flexibility, it's easy to see why the Seaweed AI video generator has gained so much attention in the short-form content and TikTok creator space—it offers freedom, completeness, and quality all in one package.

Limitations of Seaweed AI Video Generator
You shouldn't decide to use a tool based only on its advantages—it's equally important to know its downsides. This section lists several issues that the Seaweed AI video generator may have, which could affect your experience.

Seaweed AI is not a free AI video generator. It only provides one trial for each free user, and the output video quality is limited to 480p with a short generation time. To unlock more opportunities and other features—such as saving watermark-free videos, generating longer clips, or setting videos to private, you must subscribe to a paid plan.

In most cases, Seaweed AI video is clear and realistic. However, if you test multiple actions or scenes, you may encounter problems like flickering, blurred faces, or distorted graphics.
Unstable Text Generation Results
