About

LTX is an open foundation model for video, audio, and world simulation. You get full control over your AI: run LTX locally on your own hardware, fine tune it on your own IP, and generate video and audio as one unified output instead of stitching together separate tools. The latest model, LTX-2.5, is a 22B-parameter dual-stream diffusion transformer that generates native 4K video at up to 50fps, with synchronized audio and video produced in a single pass. Weights, code, and research are fully open, and independent benchmarking from Artificial Analysis ranks LTX among the top 3 AI video models globally. Access LTX three ways: download the open weights and run it yourself, license the model for on-premise deployment with enterprise support, or build on LTX Studio, the production suite for creative teams and studios. Teams at ElevenLabs, Asteria Film Co., Magnopus, and NVIDIA already build on LTX. LTX is production infrastructure for AI teams generating motion and physical environments inside their own pipelines, not a consumer app for one-off clips.

About

Ray3 is an advanced video generation model by Luma Labs, built to help creators tell richer visual stories with pro-level fidelity. It introduces native 16-bit High Dynamic Range (HDR) video generations, enabling more vibrant color, deeper contrasts, and overall pro studio pipelines. The model incorporates sophisticated physics and improved consistency (motion, anatomy, lighting, reflections), supports visual controls, and has a draft mode that lets you explore ideas quickly before up-rendering selected pieces into high-fidelity 4K HDR output. Ray3 can interpret prompts with nuance, reason about intent, self-evaluate early drafts, and adjust to satisfy the articulation of scene and motion more accurately. Other features include support for keyframes, loop and extend functions, upscaling, and export of frames for seamless integration into professional workflows.

Pros from Real Users

Pros

  • Gosh, there are too many things I love about this platform. Making cinematic movies, with CONSISTENT CHARACTERS! That's crazy, and it's also just a good video and image generator. When I'm low on computing seconds, I use LTXV Turbo because it's fast, efficient, and has amazing results.
  • 1) UI/UX – Simple, Robust, Effective. The ‘X’perience has been smooth, intuitive, and genuinely enjoyable. 2) Features – Thoughtful and Well-Designed. Every feature feels like it was built with the user in mind. 3) Speed – Unmatched. This is hands-down the fastest response system I’ve experienced.
  • I edited lots of existing images for a new project and created new images with LTX Studio. The processing was very simple and the quality was very good.
  • I really like the character design feature and the story boarding feature. The ability to change each image in real time in the story board and even animate is great. This also really helps brainstorming a story board and visualize a script to either use directly or for reference. The interactive storyboard is awesome!!
  • Many good things, such as you can easily work with different AI tools and you can create your own model as well.
  • I like the interface, the way the AI is building the storyboard, and, in general, the accuracy of the AI in generating particular types of scenes. It seems that the AI is more comfortable with particular genres (ie. children's, sci-fi, fantasy)
  • I was up and going in just minutes. I actually uploaded my new original song lyrics and LTX created scenes for me that I interwove into my bands live performance.
  • At this point, I’m enjoying the massive increase in the quality of the outputs. I’m an occasional user.
  • Easy to use!
  • Wonderful output quality, text editing is simple and the quality of interpretation in overall feel is great..

LTX is not a traditional timeline-based video editor. It is the open foundation model that generative video editing tools are built on. LTX-2.5 ships with a desktop app for fully local inference, and its production-grade reframing feature lets you outpaint video beyond its original frame while preserving composition, motion, and on-screen elements, which is useful inside an editing workflow. If you are looking for cut-and-trim editing software, LTX is not that. If you want to add AI generated shots, audio, or reframing into your own editing pipeline, on your own hardware, LTX-2.5 gives you the open model to build that on.

LTX-2.5 generates native 4K video at up to 50 frames per second, with audio and video produced together in a single pass rather than stitched together afterward. Built on a 22B-parameter dual-stream diffusion transformer with bidirectional cross-attention between the audio and video streams, LTX ranks among the top 3 AI video models globally per independent benchmarking from Artificial Analysis. You can download the open weights and run LTX locally, license it for on-premise deployment with enterprise support, or build on LTX Studio, the production suite for creative teams. Teams at ElevenLabs, Asteria Film Co., Magnopus, and NVIDIA already generate video with LTX. LTX is built for AI teams generating motion and physical environments inside their own pipelines, not for one-off social clips.

LTX is an open foundation model for video, audio, and world simulation, built by Lightricks. LTX-2.5 is a 22B-parameter dual-stream diffusion transformer that generates synchronized audio and video in a single pass, at native 4K resolution and up to 50 frames per second. Independent benchmarking from Artificial Analysis ranks LTX among the top 3 AI models globally for video generation. Unlike closed AI platforms, LTX ships with open weights, so you can download, inspect, fine-tune, and run the model on your own hardware, with no vendor lock-in and no per-generation billing. Enterprises, researchers, developers, and studios use LTX to build video, audio, and simulation capabilities directly into their own products and pipelines, from entertainment and gaming to robotics and physical AI.

LTX is a multimodal foundation model: one model generates and simulates across video, audio, and the physical world, instead of stitching together separate tools for each. LTX-2.5 produces synchronized audio and video in a single pass at native 4K resolution, so sound and motion stay aligned without post-production syncing. Because the weights and code are fully open, you can fine-tune LTX on your own audio and visual IP and run it on your own hardware. This makes LTX useful well beyond a single media type: entertainment studios, XR and virtual production teams, and robotics and simulation companies all build multimedia pipelines on the same underlying model.
