LTX-2.3

Seaweed is a foundational AI model for video generation developed by ByteDance. It utilizes a diffusion transformer architecture with approximately 7 billion parameters, trained on a compute equivalent to 1,000 H100 GPUs. Seaweed learns world representations from vast multi-modal data, including video, image, and text, enabling it to create videos of various resolutions, aspect ratios, and durations from text descriptions. It excels at generating lifelike human characters exhibiting diverse actions, gestures, and emotions, as well as a wide variety of landscapes with intricate detail and dynamic composition. Seaweed offers enhanced controls, allowing users to generate videos from images by providing an initial frame to guide consistent motion and style throughout the video. It can also condition on both the first and last frames to create transition videos, and be fine-tuned to generate videos based on reference images.

Hailuo 2.3 is a next-generation AI video generator model available through the Hailuo AI platform that lets users create short videos from text prompts or static images with smooth motion, natural expressions, and cinematic polish. It supports multi-modal workflows where you describe a scene in plain language or upload a reference image and then generate vivid, fluid video content in seconds, handling complex motion such as dynamic dance choreography and lifelike facial micro-expressions with improved visual consistency over earlier models. Hailuo 2.3 enhances stylistic stability for anime and artistic video styles, delivers heightened realism in movement and expression, and maintains coherent lighting and motion throughout each generated clip. It offers a Fast mode variant optimized for speed and lower cost while still producing high-quality results, and it is tuned to address common challenges in ecommerce and marketing content.
