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-2.5, 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-2.5 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.

Piper TTS
Piper is a rapidly operating, localized neural text-to-speech (TTS) system that is particularly optimized for devices like the Raspberry Pi 4, aiming to provide top-notch speech synthesis capabilities without the dependence on cloud infrastructure. It employs neural network models developed with VITS and subsequently exported to ONNX Runtime, which facilitates both efficient and natural-sounding speech production. Supporting a diverse array of languages, Piper includes English (both US and UK dialects), Spanish (from Spain and Mexico), French, German, and many others, with downloadable voice options available. Users have the flexibility to operate Piper through command-line interfaces or integrate it seamlessly into Python applications via the piper-tts package. The system boasts features such as real-time audio streaming, JSON input for batch processing, and compatibility with multi-speaker models, enhancing its versatility. Additionally, Piper makes use of espeak-ng for phoneme generation, transforming text into phonemes before generating speech. It has found applications in various projects, including Home Assistant, Rhasspy 3, and NVDA, among others, illustrating its adaptability across different platforms and use cases. With its emphasis on local processing, Piper appeals to users looking for privacy and efficiency in their speech synthesis solutions.

GPT-Live
GPT-Live represents an advanced iteration of voice models designed to enhance the natural interaction between humans and AI, currently utilized in ChatGPT Voice. This innovative system is engineered to create a conversational experience that closely resembles real dialogue, utilizing a full-duplex architecture that enables simultaneous listening and speaking. Throughout interactions, GPT-Live demonstrates its attentiveness with brief affirmations such as "mhmm" or "yeah," facilitates rapid exchanges, and allows for moments of silence when the user needs time to gather their thoughts. Unlike traditional systems that process each turn sequentially, GPT-Live continuously analyzes incoming audio while producing responses, making real-time decisions about when to speak, listen, pause, or even interject. Furthermore, for inquiries that necessitate web searches, intricate reasoning, or advanced tasks, GPT-Live can seamlessly refer to a more sophisticated model working in the background, retrieving and integrating the results into the ongoing dialogue without disrupting the natural flow of conversation. This capability not only enhances the interaction but also ensures a more engaging and dynamic user experience.
