kitten-inference-tts2-cu12
The Kitten TTS 2 native engine for NVIDIA GPUs, with its command-line tool. On an RTX PRO 6000 with the current model it streams its first audio after about 11 ms, and complete files take 5 to 7 times less time than with Kitten TTS 2 on vLLM or llama.cpp (one request at a time).
Install it with the Python API, which uses it:
python3 -m venv .venv && . .venv/bin/activate # Windows: py -m venv .venv, then .venv\Scripts\activate
python -m pip install -U pip # pip older than 23.3 skips the "[tts-0.8]" extra with only a warning
pip install "kitten-inference[tts-2]"
| NVIDIA GPU | Status |
|---|---|
| Compute capability 8.0 or newer (GeForce RTX 30 series and newer) | supported |
| GeForce GTX 10, GTX 16 and RTX 20 series (compute capability 6.1 and 7.5) | supported, not optimal: no bf16 tensor cores, so part of the math runs in software. Real-time factor 0.22 to 0.76 with --stream false, against 0.03 to 0.17 for RTX 30 series and newer. The audio is close to, not bit for bit the same as, a newer GPU's |
It needs NVIDIA driver R570 or newer; the CUDA 12.8 runtime is built in. Voice cloning reads the reference audio with
the ffmpeg program (sudo apt-get install -y ffmpeg, or on Windows winget install --id Gyan.FFmpeg -e).
