LTX builds open world models, AI systems that generate, simulate, and shape video, audio, and the physical world. Lightricks created LTX so that developers, studios, and enterprises can own the model they build on, not just rent access to someone else's.
The current release, LTX-2.5, is a 22B-parameter dual-stream diffusion transformer. It renders native 4K footage at up to 50fps and produces synchronized audio and video in one pass, no separate tools required. Independent benchmarks from Artificial Analysis place LTX in the top three AI video models worldwide.
There is no single way to work with LTX. Pull the open weights and run the model yourself on your own machines. Take a commercial license for on-premise deployment with full enterprise support. Or use LTX Studio, the packaged production suite for creative teams that want the model without managing the infrastructure. ElevenLabs, Asteria Film Co., Magnopus, and NVIDIA all build on it today.
If you need a quick clip for social media, look elsewhere. LTX exists for AI teams turning video, audio, and simulation into part of their own product, not a novelty.

Cartesia Sonic-3.6
Sonic is a sophisticated text-to-speech technology crafted specifically for real-time voice applications, boasting an impressive response time of under 90 milliseconds and offering seamless support for more than 40 languages. Its main goal is to enable smooth voice interactions that are marked by a tone adaptable to various contexts, consistent pacing, and speech that mimics the natural rhythm of dialogue. Sonic skillfully detects emotional subtleties in transcripts, altering its delivery to match, and it can incorporate non-verbal elements, such as laughter, directly into the audio output. Remaining true to the original text, this model produces clear sound across multiple languages and voice selections while effectively handling alphanumeric information like order numbers, phone numbers, email addresses, and IDs without any need for prior data processing. Its context-sensitive pronunciation guarantees that heteronyms are spoken accurately in relation to surrounding words, and the inclusion of customizable pronunciation dictionaries allows teams to specify how particular names and industry jargon should be articulated. This extensive methodology not only elevates the quality of interactions but also fine-tunes the user experience to accommodate a wide range of communication requirements, ultimately fostering more engaging and effective conversations. In doing so, Sonic redefines the possibilities of voice technology, making it an invaluable tool for enhancing digital communication.
