# Lights, Digital camera…
With the launch of Veo and Sora, video era has reached a brand new excessive. Creators are experimenting extensively, and groups are integrating these instruments into their advertising workflows. Nonetheless, there’s a downside: most closed methods gather your information and apply seen or invisible watermarks that label outputs as AI-generated. In the event you worth privateness, management, and on-device workflows, open supply fashions are the best choice, and several other now rival the outcomes of Veo.
On this article, we’ll evaluate the highest 5 video era fashions, offering technical data and a demo video that will help you assess their video era capabilities. Each mannequin is out there on Hugging Face and might run regionally through ComfyUI or your most popular desktop AI functions.
# 1. Wan 2.2 A14B
Wan 2.2 upgrades its diffusion spine with a Combination-of-Specialists (MoE) structure that splits denoising throughout timesteps into specialised consultants, rising efficient capability with out a compute penalty. The group additionally curated aesthetic labels (e.g. lighting, composition, distinction, shade tone) to make “cinematic” seems extra controllable. In comparison with Wan 2.1, coaching scaled considerably (+65.6% photographs, +83.2% movies), enhancing movement, semantics, and aesthetics.
Wan 2.2 studies top-tier efficiency amongst each open and closed methods. You possibly can discover the text-to-video and image-to-video A14B repositories on Hugging Face: Wan-AI/Wan2.2-T2V-A14B and Wan-AI/Wan2.2-I2V-A14B
# 2. Hunyuan Video
HunyuanVideo is a 13B-parameter open video basis mannequin educated in a spatial–temporal latent house through a causal 3D variational autoencoder (VAE). Its transformer makes use of a “dual-stream to single-stream” design: textual content and video tokens are first processed independently with full consideration after which fused, whereas a decoder-only multimodal LLM serves because the textual content encoder to enhance instruction following and element seize.
The open supply ecosystem consists of code, weights, single- and multi-GPU inference (xDiT), FP8 weights, Diffusers and ComfyUI integrations, a Gradio demo, and the Penguin Video Benchmark.
# 3. Mochi 1
Mochi 1 is a 10B Uneven Diffusion Transformer (AsymmDiT) educated from scratch, launched underneath Apache 2.0. It {couples} with an Uneven VAE that compresses movies 8×8 spatially and 6x temporally right into a 12-channel latent, prioritizing visible capability over textual content whereas utilizing a single T5-XXL encoder.
In preliminary evaluations, the Genmo group positions Mochi 1 as a state-of-the-art open mannequin with high-fidelity movement and robust immediate adherence, aiming to shut the hole with closed methods.
# 4. LTX Video
LTX-Video is a DiT-based (Diffusion Transformer) image-to-video generator constructed for velocity: it produces 30 fps movies at 1216×704 sooner than actual time, educated on a big, numerous dataset to stability movement and visible high quality.
The lineup spans a number of variants: 13B dev, 13B distilled, 2B distilled, and FP8 quantized builds, plus spatial and temporal upscalers and ready-to-use ComfyUI workflows. If you’re optimizing for quick iterations and crisp movement from a single picture or quick conditioning sequence, LTX is a compelling alternative.
# 5. CogVideoX-5B
CogVideoX-5B is the higher-fidelity sibling to the 2B baseline, educated in bfloat16 and really helpful to run in bfloat16. It generates 6-second clips at 8 fps with a set 720×480 decision and helps English prompts as much as 226 tokens.
The mannequin’s documentation reveals anticipated Video Random Entry Reminiscence (VRAM) for single- and multi-GPU inference, typical runtimes (e.g. round 90 seconds for 50 steps on a single H100), and the way Diffusers optimizations like CPU offload and VAE tiling/slicing have an effect on reminiscence and velocity.
# Selecting a Video Era Mannequin
Listed here are some high-level takeaways for serving to select the correct video era mannequin in your wants.
- In order for you cinema-friendly seems and 720p/24 on a single 4090: Wan 2.2 (A14B for core duties; the 5B hybrid TI2V for environment friendly 720p/24)
- In the event you want a big, general-purpose T2V/I2V basis with robust movement and a full open supply software program (OSS) toolchain: HunyuanVideo (13B, xDiT parallelism, FP8 weights, Diffusers/ComfyUI)
- In order for you a permissive, hackable state-of-the-art (SOTA) preview with fashionable movement and a transparent analysis roadmap: Mochi 1 (10B AsymmDiT + AsymmVAE, Apache 2.0)
- In the event you care about real-time I2V and editability with upscalers and ComfyUI workflows: LTX-Video (30 fps at 1216×704, a number of 13B/2B and FP8 variants)
- In the event you want environment friendly 6s 720×480 T2V, strong Diffusers assist, and quantization all the way down to small VRAM: CogVideoX-5B
