Based on the published resources, NVIDIA Magpie TTS (https://huggingface.co/blog/nvidia/magpie-tts-multilingual-voice-agents) is an open-weights solution designed for building low-latency multilingual voice agents with full deployment control. On the other hand, Meta Muse Glimmer (https://huggingface.co/blog/muse-glimmer) is described as a local, agentic, multimodal, and open-source model. While Magpie TTS focuses specifically on multilingual voice agent deployment, Muse Glimmer offers a broader multimodal agentic capability.
