| # whisper-large-v2 |
|
|
| [BaseRT](https://github.com/basecompute/baseRT) `.base` build of |
| [`openai/whisper-large-v2`](https://huggingface.co/openai/whisper-large-v2), |
| OpenAI's 1.55B-parameter Whisper speech-recognition model, |
| for fast local transcription on Apple Silicon. |

| ## Files |
|
|
| | File | Precision | Size | |
| |------|-----------|------| |
| | `whisper-large-v2-F16.base` | float16 | 3.10 GB | |
| | `whisper-large-v2-Q8.base` | 8-bit linears, f16 embeddings/conv/norms | 1.68 GB | |
| | `whisper-large-v2-Q4.base` | 4-bit linears, f16 embeddings/conv/norms | 987 MB | |
|
|
| F16 and Q8 are transcription-quality equivalent (Q8 passes the same |
| word-error parity gates against reference openai-whisper). Q4 is the |
| smallest and remains accurate; on some smaller variants it can |
| occasionally repeat a word in timestamped beam decoding. |
|
|
| ## Usage |
|
|
| ```bash |
| curl -LsSf https://basecompute.co/install.sh | sh |
| basert serve --model whisper-large-v2-F16.base |
| ``` |
|
|
| `POST /v1/audio/transcriptions` (multipart or JSON) returns `json`, `text`, |
| `srt`, `vtt`, or `verbose_json` (with per-segment `avg_logprob` / |
| `no_speech_prob` / `compression_ratio` / `temperature` and the detected |
| `language`), with optional SSE streaming and `POST /v1/audio/translations`. Supported |
| request fields: `language` (or `"auto"` to detect), `prompt` |
| (initial prompt / vocabulary bias), `task` (`transcribe`/`translate`). Or transcribe directly |
| from the CLI: |
|
|
| ```bash |
| basert-transcribe whisper-large-v2-F16.base audio.wav --lang auto |
| ``` |
|
|
| Multilingual: pass `language` (e.g. `--lang de`), or `auto` to detect, across the 99 supported languages. `task=translate` produces English from any source language (also via `POST /v1/audio/translations`). |
