The fixed browser sampler bakes the checkpoint card's cooler long-form defaults: audio temperature 0.6, top-p 0.9, top-k 25, and repetition penalty 1.2. Do not recreate it with Transformers 5.x; this remote-code model is verified with Transformers 4.57.1.

The TTS MatMul weights use asymmetric block-32 MatMulNBits INT4 with FP32 graph I/O. The full codec decoder is FP16; the reference encoder and streaming decoder remain FP32. This is the low-download option. The FP16 repository remains the recommended speed path because WebGPU autoregressive generation measured substantially faster in ONNX Runtime Web 1.27.

Build	Frames	Termination	Persian Whisper result
New checkpoint FP16	22	audio EOS	`سالو` (Whisper-base smoke)
New checkpoint INT4 block-64	15	audio EOS	`سالا` (Whisper-base smoke)
New checkpoint INT4 block-32	17	audio EOS	`سالام` (Whisper-base smoke)

Actual browser profiling on the included 68-character Persian demo, ONNX Runtime Web 1.27 WebGPU:

FP16 synthesis pipeline: 10.86 s before GPU-resident KV-cache optimization
FP16 synthesis pipeline: 6.22 s with GPU-resident KV cache
INT4 block-32 synthesis pipeline: 33.28 s; smaller download, but not the speed default
greedy Negara G2P matched 5-beam output on five representative Persian sentences while reducing warm G2P latency from 6.7–8.1 s to 1.3–1.8 s

The web app overlaps G2P with model loading, caches shared sidecar reads, compiles only the active sampler, keeps autoregressive KV tensors on GPU, and prewarms after the first text interaction.
