Our take

Written Sep 4, 2026

Parakeet is a tiny downloadable speech-to-text model from NVIDIA that turns audio into written words. It covers 25 languages and is built for speed rather than peak accuracy, transcribing an hour of audio in under a second on benchmark hardware.

Who should pick it

Pick this for batch transcription where speed matters, or when you need a permissively licensed model with broad language coverage. It handles podcasts, video and recorded meetings better than most alternatives, and copes well with accented speech. Skip it if you need hosted inference, the absolute best accuracy on clean read-aloud audio, or speaker separation and timestamps.

The case for it

  • Extremely fast: 6,098 times real time on benchmark hardware, an hour of audio in under a second.
  • Strong on everyday internet audio: 8% word-error rate on podcasts and video, better than most models.
  • Resilient on hard conditions: 9.4% error on recorded meetings and 10.8% on accented speech, both better than most.
  • Broad language coverage and permissive licence: 25 languages including Spanish, French and German, with Creative Commons Attribution 4.0 allowing commercial use.

The case against it

  • Mediocre on clean read-aloud audio: 1.51% error, worse than most models on that condition.
  • Near the middle of the field overall: 5.66% average error across nine test sets.
  • No hosted providers currently listed; you must run it yourself.

Percentage of words wrong on each set, lower better. Bars are scaled to this model's own worst case; the placing beneath each rate is against every model measured on that set.

The figures above come from the Open ASR Leaderboard, an independent public test that runs every model on the same recordings. It is the only measurement of transcription quality we know of, so there are no other scores to show.

Each of these is the same transcription job on a different kind of recording, so together they say where it holds up and where it slips — not how closely it follows an instruction.

These cards answer whether Parakeet TDT 0.6b v3 loads, not how fast it transcribes. Throughput figures for a transcription model come from its text decoder, so treat this as a fit answer rather than a speed one.

What we do not know about this model yet

  • We hold no measured file for it, so all 3 sizes on this page are calculated from the parameter count.
  • Nothing we hold says whether an endpoint streams, so we do not show it either way.
