Linum v2 - 720p

Small text-to-video generation model trained from scratch by Linum AI. Read the launch blog post.

Model Description

Linum V2 is a 2B parameter Diffusion Transformer (DiT) based text-to-video model that generates 720p (1280x720) videos at 24 FPS from text prompts.

Quick Start

See the full documentation at: GitHub - Linum-AI/linum-v2

First, install uv:

curl -LsSf https://astral.sh/uv/install.sh | sh

Then clone and generate your first video:

git clone https://github.com/Linum-AI/linum-v2.git
cd linum-v2
uv sync
uv run python generate_video.py \
    --prompt "In a charming hand-drawn 2D animation style, a rust-orange fox with cream chest fur and alert triangular ears grips a cherry-red steering wheel with both paws, its bushy tail curled on the passenger seat. Stylized trees and pastel houses whoosh past the windows in smooth parallax layers. The fox's golden eyes focus intently ahead, whiskers twitching as it navigates a winding country road rendered in soft watercolor textures." \
    --output fox.mp4 \
    --seed 20 \
    --cfg 7.0

Weights are downloaded automatically on first run (~20GB).

Speed Benchmarks (H100, 50 steps)

For lower VRAM, use the 360p model.
