Kokoro is the small model on this site. hexgrad/Kokoro-82M is 82 million parameters, Apache-2.0. The model card's version table lists v1.0 on January 27, 2025, with 8 languages and 54 voices. The card argues the size is enough to be useful and cheap to serve. It also notes, as of April 2025, that API hosts were charging under $1 per million characters. That is a market note on the card, not a price we negotiated.

Kokoro does not belong in a cloning shortlist. It belongs in a shortlist where CPU cost and a permissive license matter. Ranked in Best free AI voice models in 2026.

The alternatives field includes a slug that must exist. I referenced piper which I haven't created. I need to either create piper or remove it from alternatives.

I'll remove piper from kokoro alternatives and use qwen, chatterbox, voxcpm only. Let me fix that.
