Hey HN, after our 13B release we've been working on a faster version of our open-source video model and we're excited to share it. We started with a 13B base model that already had competitive generation speeds (e.g. 55s for a 5s video on an H100 — faster than any other model out there). But we wanted to push it further to allow everyone to quickly iterate over their video generations. So we built a distilled version focused on speed without sacrificing temporal or spatial coherence. With the Distilled model, you can now generate 5-second 720p videos in about 9.5 seconds on an H100, and…

In plain words
LTXV 13B Distilled is an open-source video generation model designed to create 5-second 720p videos quickly. It generates videos in approximately 9.5 seconds on an H100 GPU and around 1.5 minutes on consumer GPUs like the RTX 5090, prioritizing speed while maintaining temporal and spatial coherence. The distilled model is interoperable with the base 13B model, allowing developers to mix and match them in rendering pipelines for flexible workflows. It's intended for developers and creators who need fast video iteration and experimentation.

Audio-to-Video with LTX-2Mar 2026 · magichour.ai · ▲23LTX-2 is an open-source diffusion model that combines video and audio. Visually it's not at the level of Seedance 2.0, Veo 3.1, or Sora 2, but it’s open-weights, so anyone can play with it. I wanted to see how good it is at generating video from just audio. Off-the-shelf, it's not very good, but I found that if you run the audio through Gemini to generate a prompt, then feed that into LTX-2, in addition to the audio, the output matches the audio much more often. Foley sounds work particularly well, and one fun use case is uploading audio of yourself to see what AI thinks you look like.…
X-PilotApr 2026 · x-pilot.ai · ▲328Hi HN, I'm Heshan, founder of X-Pilot. We're building an AI Video Generator for online courses and educational content. Unlike most text-to-video generator that render videos directly from models (which often produce random stock footage unrelated to the actual content), we take a code-first approach: generate editable code layers, let users verify/refine them, then render to video. The Problem We're Solving Most AI video generators treat "education" and "marketing" the same—they optimize for "looks good" rather than "logically accurate." When you feed a technical tutorial or course…
