Most AI video tools hand you a black box: closed weights, a subscription, and no way to see what is happening under the hood. LTX takes the opposite approach. Built by Lightricks, LTX is an open foundation model that generates and simulates across video, audio, and the physical world, and it puts the weights, the code, and the control in your hands.
At the center of the model is LTX-2.3, a 22B-parameter dual-stream diffusion transformer that produces native 4K video at up to 50 frames per second, with audio and video generated together in a single pass rather than stitched together afterward. Artificial Analysis, an independent benchmarking group, currently ranks LTX among the top three AI video models in the world.
You choose how you want to use it. Download the open weights and run LTX-2.3 on your own hardware. License the model for on-premise deployment backed by enterprise support. Or build directly on LTX Studio, the production suite that turns the model into a full creative workflow. Companies like ElevenLabs, Asteria Film Co., Magnopus, and NVIDIA already rely on LTX for their own work.
LTX is not built for one-off social clips. It is infrastructure for teams that generate motion, audio, and physical environments as part of their own products and pipelines.

HappyHorse 1.1
HappyHorse-1.1-T2V is a QwenCloud video generation model that creates videos from text descriptions. The model is designed to improve text-to-video quality through stronger semantic understanding, cinematic shot control, and dynamic motion rendering. HappyHorse-1.1-T2V helps users produce videos that better reflect the intent of a prompt, including scene atmosphere, character movement, physical dynamics, and visual consistency. It supports video generation at 480P, 720P, and 1080P, with pricing based on generated video seconds. Developers can call the model through the DashScope API and configure parameters such as resolution, ratio, and duration. The model is not open source and is offered as a hosted API through QwenCloud. Rate limits include 300 requests per minute, 5 concurrent requests, and an async queue limit of 500 tasks. QwenCloud also provides free quota for testing and API key access for production usage. By combining text-to-video generation, semantic prompt understanding, cinematic control, motion rendering, API access, and scalable rate limits, HappyHorse-1.1-T2V helps teams build AI video creation workflows.

Seedance 2.5
Seedance 2.5 is a video creation model from ByteDance Seed designed to move AI video generation from short clips toward complete creative works. Built on the multimodal audio-video joint-generation architecture introduced with Seedance 2.0, the model focuses on foundational generation, reference-based generation, long-form storytelling, and editing control. Seedance 2.5 can generate up to 30 seconds of high-quality audio-video content in one pass and supports multiple rounds of extension. This allows users to create multi-minute videos while maintaining consistency across characters, environments, shot transitions, pacing, motion, and sound. The model supports up to 30 image references, 10 video references, and 10 audio references in a single generation request. It can preserve visual composition, characters, props, voices, scene style, motion paths, and creative intent across complex multi-subject videos. Editing capabilities include timestamp-level changes, green screen workflows, camera perspective editing, reference-based editing, and targeted modifications to characters, actions, or plot elements. Seedance 2.5 is rolling out through Jimeng AI and Doubao Pro, with API access planned through BytePlus ModelArk. By combining long-form generation, multimodal references, cinematic quality, synchronized audio-video output, and professional editing control, Seedance 2.5 helps creators produce more coherent and polished AI videos.
