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
curl -LsSf https://basecompute.co/install.sh | sh
basert serve --model whisper-medium-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:
basert-transcribe whisper-medium-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).
