My team has been cooking nonstop for a while... and I’m so excited to finally share what we’ve been building!!!
Today, we’re releasing four open models, many of which are the best models of the same size 🥳!!!
tldr;
1) Raon-Speech: 9B SOTA speech LLM
2) Raon-SpeechChat: 9B full duplex model
3) Raon-OpenTTS: 0.3B/1B open-data-open-weight SOTA TTS
4) Raon-VisionEncoder: 0.4B vision encoder trained only with public data

1) Raon-Speech (9B)
Raon-Speech is a speech LLM (LLM speech understanding speech generation).
It's a bilingual model (English/Korean), and it's ranked #1 on both leaderboards 😎
tldr; it's the best open-model alternative to ChatGPT voice mode.
Model:

Tech report:
huggingface.co/KRAFTON/Raon-…
Web demo:
raon.krafton.ai/ ("Speech Chat" menu here. "auto" is a bit unstable, so use "manual" and choose the language!)
2) Raon-SpeechChat (9B)
While a speech LLM is useful, it’s kind of like a walkie-talkie. A full-duplex model is more like a phone, so it is even more useful in many applications.
That’s why we also built and are releasing Raon-SpeechChat. Again, on several quantitative evaluation metrics, Raon-SpeechChat scored the best on average.

3) Raon-OpenTTS (0.3B, 1B)
We’re also releasing Raon-OpenTTS, a state-of-the-art open-data, open-weight TTS model.
Model data:

The 1B model and a detailed tech report are coming soon!
4) Raon-VisionEncoder (0.4B)
Last but not least, we’re releasing Raon-VisionEncoder, a vision encoder trained from scratch using only public data. It closely matchs the SOTA vision encoder quality too!

That’s it!
I’m incredibly proud of what my team has built!
My AI research team at KRAFTON (
@Krafton_AI), which undoubtedly is the most cracked team in Korea, has been cooking nonstop for a while for this 😅...
This is just the beginning of our planned model releases, so stay tuned!
ps1/ Ah, by the way, you may ask why “Raon”?
“Raon” is an old Korean word meaning happy.
And, well, we’re kRAftON :-)
ps2/ KRAFTON is one of the four teams participating in Korea’s national frontier-model project, together with SK Telecom. We’re training something very exciting together... and more to come soon!
