- Yes
What you need to run it
- Mac
- Yes. Any Apple Silicon Mac (M1 or newer) with at least 8 GB (16 GB recommended) of memory. Newer chips are faster, but memory is what decides whether it runs.
- Windows / Linux PC
- NVIDIA works best. A graphics card with at least 4 GB (8 GB recommended) of video memory.
- No graphics card
- Works. Runs on a normal computer's processor, just slower.
Built for NVIDIA's NeMo, but community ports (parakeet-mlx on Mac, ONNX on CPU) run it without an NVIDIA card.
Numbers are for: 0.6B (v2 English / v3 multilingual). Our estimate from the model’s size — the maker publishes no figure.
Strengths
- Top-of-leaderboard English accuracy
- Fast inference on NVIDIA GPUs via NeMo
- Permissive CC BY 4.0 license
Weaknesses
- Peak accuracy is the English v2 model; multilingual needs the separate v3 model
- Tightest performance is in NVIDIA's NeMo runtime

Change log
- — Added hardware requirements (Mac support, memory, NVIDIA). Source: HF model card + mlx-community/parakeet-tdt-0.6b-v3 + size.
- — Verified the Parakeet entries are unchanged. Newer NVIDIA streaming option: nvidia/nemotron-3.5-asr-streaming-0.6b, released 2026-06-04 per its model card, under the OpenMDW-1.1 licence (not CC BY 4.0), with about 978k Hugging Face downloads/month. Not added as a separate entry here.
- — Verified current — no Parakeet v4 exists. Note nvidia/parakeet-unified-en-0.6b (2026) now beats this model both offline and dramatically in streaming, so the 'top-of-leaderboard English accuracy' claim needs a re-check against the current Open ASR leaderboard.
- — Repointed from parakeet-tdt-1.1b to current flagship parakeet-tdt-0.6b-v2 (English, 2025-05-01); added parakeet-tdt-0.6b-v3 (multilingual, 2025-08-14).
- — Initial entry.
