## What stands out

- #1 open-weights TTS on Artificial Analysis (found after launch): ~1,206-1,215 Elo in the Artificial Analysis Speech Arena, ~90 points above Fish Audio S2 Pro, #6 overall at launch — the leading open-weights TTS as of Sept 2026. Source: https://x.com/ArtificialAnlys/status/2092399623839326550
- Clone + design + direct in one 3B checkpoint, <40 ms TTFA: Voice cloning from reference audio, voice design from text descriptions, voice direction (tone/emotion keeping identity), vocal events (laughs, coughs); streaming TTFA under 40 ms on H100 with fast path, RTF 0.32.

## Notes

Model card lists English + Chinese; the Artificial Analysis post mentions 50 languages (possibly the hosted model) — unresolved. Needs 12 GB VRAM (24 GB recommended), CUDA/Linux. Weights are NOT commercially usable without a BreezeBlue subscription. Some secondary blogs claim it is the 'first open-weight model to beat ElevenLabs' flagship' — unverified and contradicted by the AA leaderboard (Eleven v4 far ahead).
