Today, we're excited to announce a beta release of Zonos, a highly expressive TTS model with high fidelity voice cloning. We release both transformer and SSM-hybrid models under an Apache 2.0 license. Zonos performs well vs leading TTS providers in quality and expressiveness.
Zyphra is expanding! Join our growing team in Palo Alto. We have multiple roles open across multimodal foundation models, RL, product, and infrastructure. Check them out here: jobs.ashbyhq.com/zyphra
Another mature reasoning RL stack from perhaps the highest-taste Western open source AI company
Training Recipe: We train using the PRIME framework and use iterative context lengthening to encourage efficient reasoning traces. Even with responses truncated to 2048 tokens, ZR1-1.5B still outperforms Qwen2.5-Math-7B-Instruct!
@ZyphraAI have launched their first Text to Speech model, Zonos-v0.1 - now the leading open weights Text to Speech model in Artificial Analysis Speech Arena. Zonos-v0.1 is currently scoring a Speech Arena ELO of 1020, just behind proprietary speech models available on Google…
We apologize if you’ve been experiencing performance issues on our Playground/API over the past 24 hours. Since yesterday’s release, we’ve seen higher than expected activity, but we’re working diligently to troubleshoot. Thanks to everyone who has tried Zonos!
The simulation is sounding ever smarter... from the DeepSeek of the free world: @ZyphraAI
deepseek of the west, and it's no surprise that millidge is there
