Whisper Tiny ONNX

Selected ONNX exports of OpenAI Whisper Tiny for ONNX Runtime and Unity AI Inference 2.6.1 (Sentis).

The FP32 split decoder is sourced unchanged from onnx-community/whisper-tiny revision ff4177021cc41f7db950912b73ea4fdf7d01d8e7. The BNB4 files are intended for ONNX Runtime. KitsuMate provides the ONNX mel preprocessing graph and this packaging; OpenAI and the ONNX Community contributors retain authorship of the model and conversion work.

Engine support

Files	Precision	ONNX Runtime	Unity AI Inference 2.6.1
encoder_model.onnx, decoder_model.onnx, decoder_with_past_model.onnx	FP32	Yes	Yes, CPU validated
encoder_model_bnb4.onnx, decoder_model_merged_bnb4.onnx	BNB4	Yes	No
mel.onnx, tokenizer.json	Shared preprocessing	Yes	Yes

The unsuffixed files are FP32. All ONNX files are kept directly under onnx/ so additional precisions can use filename suffixes without duplicating shared assets.
