Chatterbox Nano ONNX

KitsuMate mirror of the independent owensong/chatterbox-nano-ONNX conversion for reproducible Unity and ONNX Runtime downloads. This is not an official Resemble AI ONNX release.

The repository contains the conversion's only complete published profile:

Stage	File	Precision
Text and speech-token embeddings	`embed_tokens_fp16.onnx`	FP16
Reference speech encoder	`speech_encoder_q4f16.onnx`	Q4F16
Autoregressive language model	`language_model_q4f16.onnx`	Q4F16
Conditional acoustic decoder	`conditional_decoder_q4.onnx`	Q4

Each graph must remain beside its matching .onnx_data file. This mixed profile is identified as q4 by KitsuMate because the Q4 decoder is its largest component.

The conversion has passed an end-to-end CPU smoke test, but has not received a representative speech-quality or device-compatibility evaluation. It is non-streaming and supports English only.
