Output Format

[00:00:00.320 --> 00:00:02.220]  (Speaker 1) And so, my fellow Americans,
[00:00:03.020 --> 00:00:07.640]  (Speaker 1) ask not what your country can do for you,
[00:00:08.110 --> 00:00:10.540]  (Speaker 1) ask what you can do for your country.
[00:00:11.440 --> 00:00:15.580]  (Speaker 2) And so, my fellow Americans, ask not...

Architecture

Stock Whisper encoder (24L, 80 mel, Conv1d) with 4x temporal merge, VQAdaptor, time markers every 5s, and Qwen3-0.6B LM decoder. Output: [timestamp][Sxx]text[timestamp] format with speaker labels.

Diff Harness

All 4 stages pass at cos=1.000 on both F32 and Q4_K:

| Stage | cos_min | max_abs |

|-------|---------|---------|

| mel_spectrogram | 1.000000 | 1.20e-04 |

| conv_stem_out | 1.000000 | 6.11e-05 |

| encoder_output | 1.000000 | 1.24e-04 |

| audio_embeds | 1.000000 | 1.35e-02 |

• What was done here: format conversion and/or quantisation only (GGUF). No training, no fine-tuning, no merging, no distillation, no change to architecture, vocabulary or capability. Only the numeric representation of the upstream weights differs.
• Training data: documented — where it is documented at all — by the upstream provider; see the upstream model card. No training data was used, added or selected by this repository. No training-content summary was found on the upstream model card at the time of writing; that documentation gap is upstream's and is not filled here.
