1/ 🎙️a tiny two-person team out of Korea just dropped Dia, a state-of-the-art open-source speech model with 1.6 billion parameters. It's like if ElevenLabs and ChatGPT had a hyper-expressive, emotionally intelligent baby. Let's break it down 🧵👇

3/ Fully open-source under Apache 2.0, Dia is free to use commercially. You can grab the weights and code off GitHub or Hugging Face. It’s optimized for PyTorch 2.0+ and CUDA, so if you’ve got a halfway-decent GPU (10GB VRAM+), you’re good to go.

4/ Early benchmarks say it outperforms ElevenLabs and OpenAI’s models when it comes to emotional range and dialog-style speech. So yeah, this isn’t just text-to-speech—it’s vibe-to-speech. Perfect for game devs, narrators, or anyone making AI content that needs ✨feels✨.

5/ Nari Labs—the duo behind Dia—are proof that small teams can make serious waves. They're also super clear: no shady stuff. No impersonations. No fake news. Just raw, expressive AI voice tech for everyone to build cool things with. Open-source W.

2/ What makes Dia wild is how real it sounds. It reads a line like “I’m fine (laughs)” and actually puts the laugh in there. Plus, it supports zero-shot voice cloning—you just give it a voice clip and boom, it talks like that person. Straight outta sci-fi.
