IndicF5 MNN

MNN exports of ai4bharat/IndicF5 (DiT + Vocos), including fp16 and int8 weight-quantized variants.

Files

DiT

File	Approx. size
indicf5_dit_fp32.mnn	~1.3 GB
indicf5_dit_fp16.mnn	~646 MB
indicf5_dit_int8wq.mnn	~347 MB
indicf5_dit_fp16_int8wq.mnn	~646 MB

Vocos

File	Notes
indicf5_vocos_fp32.mnn	static
indicf5_vocos_fp32_dynamic.mnn	variable mel frames (recommended for audio)
indicf5_vocos_fp16.mnn
indicf5_vocos_int8wq.mnn	static
indicf5_vocos_int8wq_dynamic.mnn	variable mel frames
indicf5_vocos_fp16_int8wq.mnn

Sample WAVs (fp32 / int8wq Vocos decode) are under samples/. Bench numbers: quant_benchmark.json.

Notes

• Prefer *_dynamic.mnn Vocos models for full-length audio (call resizeTensor with a tuple shape, then resizeSession).
• Path used for samples: PyTorch mel → MNN Vocos.
• Still not realtime on Apple M1 CPU for full DiT ODE + Vocos.
