What is LTX-2?
LTX-2 is Lightricks' open-weights audio-video foundation model, a diffusion transformer that generates synchronized video and sound in one model. The repository is the official Python inference package and LoRA trainer, with pipelines for the LTX-2.5 checkpoints published on Hugging Face.
It offers several speed and quality modes, latent upscaling and distilled variants. The full model download is large (around 66 GB for the main set), so it is aimed at people with serious GPUs; Lightricks also offers API access.

Mochi
Genmo's open video generation model.
ManimGX
ManimGX, from Academa, is an open-source animation engine for AI agents that renders math and 3D explainer videos from Manim CE's Python API on a Rust and wgpu GPU core, many times faster than Manim CE, and can also run in the browser.
CogVideoX
Open text-to-video and image-to-video models from Zhipu AI (Z.ai) and Tsinghua.
Frametell
Frametell turns an idea, PDF, slides or notes into a narrated, hand-drawn explainer film: a director agent storyboards it with you for approval, writes and voices the script and draws every page, as an open-source Mac app or Frametell Cloud.
Google Flow
Google's AI filmmaking tool built on Veo. Generate and extend cinematic shots, keep characters consistent and build scenes, with a Flow agent to help.
iArt
iArt is an AI motion graphics agent that turns a text prompt, or uploaded images, PDFs, slide decks, audio or a web link, into animated scenes. It writes real animation code scene by scene (layout, typography, timing, transitions), so text stays exactly spelled and you can refine the result by chatting ("make the title two seconds shorter"). It handles explainers, logo animations, kinetic typography, animated charts, lower thirds and audio-synced captions, adds AI voiceover or a cloned voice, and exports MP4 (1080p on Pro, 4K on Ultra) or transparent WebM overlays.
