VoxCPM

the newest high-star expressive open model

free — Apache-2.0 (weights included)#developers-wanting-the-n#expressive-open-model

a young, tokenizer-free, context-aware open model with zero-shot cloning and an apache-2.0 licence you can ship — high stars, but fewer production references than kokoro or cosyvoice, so check the arenas rather than take claims on faith.

voxcpm, from openbmb, is a compact (~0.5b) tokenizer-free model with context-aware zero-shot cloning and expressive output, apache-2.0 and therefore commercial-safe, with a realtime voxcpm2 variant and a hosted listing on wiro at $0.0001/char. it's the newest of the high-star open expressive models and an attractive option for developers who want something current and permissive.

being young, it has fewer production references than kokoro or cosyvoice, and its quality standing should be checked on tts arena v2 rather than asserted. as a fresh, permissive, expressive open model, it rounds out the list.

the description above is ours, condensed from the ranking. pricing moves — check it on the vendor's own page before you rely on it.

our verdict

a young, tokenizer-free, context-aware open model with zero-shot cloning and an apache-2.0 licence you can ship — high stars, but fewer production references than kokoro or cosyvoice, so check the arenas rather than take claims on faith.

we researched this category against vendors' own pricing pages and licence files. that is where this line comes from — not from the vendor, and not from anything they paid for.
