Zyphra Zonos Description
Zyphra is thrilled to unveil the beta release of Zonos-v0.1, which boasts two sophisticated and real-time text-to-speech models that include high-fidelity voice cloning capabilities. Our release features both a 1.6B transformer and a 1.6B hybrid model, all under the Apache 2.0 license. Given the challenges in quantitatively assessing audio quality, we believe that the generation quality produced by Zonos is on par with or even surpasses that of top proprietary TTS models currently available. Additionally, we are confident that making models of this quality publicly accessible will greatly propel advancements in TTS research. You can find the Zonos model weights on Huggingface, with sample inference code available on our GitHub repository. Furthermore, Zonos can be utilized via our model playground and API, which offers straightforward and competitive flat-rate pricing options. To illustrate the performance of Zonos, we have prepared a variety of sample comparisons between Zonos and existing proprietary models, highlighting its capabilities. This initiative emphasizes our commitment to fostering innovation in the field of text-to-speech technology.

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.

Miso TTS
Miso Labs specializes in developing emotive voice foundation models aimed at enabling developers to create voice agents that exhibit a warm, human-like quality rather than sounding robotic or sluggish. Their premier offering, Miso TTS, features an impressive 8-billion-parameter transformer model that excels in generating emotive speech and dialogue, with open source weights accessible on Hugging Face and an API set to launch shortly. Miso is optimized for real-time conversational interactions, ensuring responses occur within 110ms to maintain a natural flow and eliminate the awkward silences often associated with AI voice agents. In addition, it offers one-shot voice cloning capabilities, which enable users to replicate a voice from just a ten-second audio sample while ensuring the agent's voice remains consistent throughout a conversation. Furthermore, Miso Labs prioritizes local and sovereign deployment options, providing open source models designed for local usage along with on-premises support for enterprise clients who need to secure their sensitive data. This comprehensive approach not only enhances user experience but also gives organizations the flexibility they need in managing their voice technology.

Chirp 3
Google Cloud's Text-to-Speech API has unveiled Chirp 3, a feature that allows users to develop custom voice models by utilizing their own high-quality audio recordings. This innovation streamlines the process of generating unique voices for audio synthesis via the Cloud Text-to-Speech API, catering to both streaming and long-form text applications. Due to safety protocols, access to this voice cloning feature is limited to select users, and those interested in gaining access must reach out to the sales team for inclusion on the allowed list. The Instant Custom Voice capability supports a variety of languages, such as English (US), Spanish (US), and French (Canada), ensuring a broad reach for users. Moreover, this service is operational across multiple Google Cloud regions and offers a range of supported output formats, including LINEAR16, OGG_OPUS, PCM, ALAW, MULAW, and MP3, depending on the chosen API method. As voice technology continues to evolve, the possibilities for personalized audio experiences are expanding rapidly.
