Is VieNeu-TTS or VieNeu-TTS-0.3B smaller?

Both publish quantizations; compare the table for the exact sizes.

Which uses less memory at long context?

VieNeu-TTS — its KV cache at 32K context is 2.3x smaller, because of how its attention layers cache.

Model comparison

VieNeu-TTS vs VieNeu-TTS-0.3B

These two publish different quantization sets; the table below has the exact sizes. At long context the gap widens: VieNeu-TTS's KV cache at 32K is 2.3× smaller, which usually matters more than the difference in weights.
