+### About `tts-large/`
+
+This is the premium 7B/9B variant of long-form multi-speaker TTS. Microsoft originally published it at `microsoft/VibeVoice-Large` with full MIT license, then **removed the repo on 2025-09-05** along with the demo scripts (same RAI cleanup that removed `modeling_vibevoice_inference.py`). The MIT license remains in force on the released weights — this mirror sources from [`aoi-ot/VibeVoice-Large`](https://huggingface.co/aoi-ot/VibeVoice-Large), a community preserve uploaded on 2025-09-04 (one day before Microsoft's pull) that retains the full original release.
+
+**Differences from `tts-1.5b/`:**
+- Same `Speaker N:` script format, same voice-cloning workflow (pass per-speaker reference clips)
+- Larger backbone → marginally better prosody and speaker consistency at the cost of ~3× weight size and ~3× VRAM
+- **Shorter** max output: 32K context = ~45 min vs the 1.5B's 64K context = ~90 min. The 1.5B is the better choice for long podcasts; the Large is the better choice for short premium-quality dialog.
+
 ### About `realtime-0.5b/voices/*.pt`
 
 These are pickled KV-cache dictionaries (output of running each voice prompt through the full model once, then `torch.save`'d). They are **not flat tensor maps** so they cannot be converted to safetensors — they must be loaded with `torch.load(..., weights_only=False)`. Each is 2–7 MB. Microsoft does not publish the acoustic tokenizer that would let users generate new ones, so this set of 25 is the complete preset library.
