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
SFX v3 is ElevenLabs’ text-to-sound-effects model, offered through the ElevenCreative platform and ElevenAPI rather than as a separate standalone application. It turns written prompts into short audio clips for video, games, interactive media, film, trailers, Foley, and ambient sound design. Prompts can describe multiple actions or sounds in sequence, as well as musical elements and vocals. In ElevenCreative, users can generate effects in the Sound Effects area, Flows, Studio, and Music Editor; developers can call the sound-effects API using the model ID eleven_text_to_sound_v3 to add generation to their own applications and workflows. Available controls include duration, looping, and prompt influence, and generation can produce effects up to 30 seconds. SFX v3 is in limited access, so availability may vary by account and region.

CategoriesLTX 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. |
