Kitten-TTS 2: 1.58-bit TTS Runs on CPU!
“When your CPU outperforms a $30K GPU, it's time to cry.”
The story behind the toon
A 1.58-bit TTS model so efficient it runs on a CPU, making GPU salesmen weep into their $30,000 Blackwell chips.
What happened: A super-efficient text-to-speech model that runs on a CPU and clones voices in many languages.
Why it matters: It makes high-quality voice AI cheap and accessible without expensive GPUs.
This Neural Toon is based on the story “Kitten-TTS 2: New Open-source SOTA 1.58 bit TTS (CPU-only with voice cloning, multilingual, emotion control)”.
