Every model from this lab and its older versions: https://www.anchorterminal.com/open-weights/#nvidia. ## Assessment One English model for batch and live transcription, with a well-documented data list and an NVIDIA team that answers. It runs only in NVIDIA NeMo from a pickle-format archive, with no safetensors, GGUF or quantised build, returns plain text without timestamps, and hasn't changed since June. ## Facts | Field | Value | | --- | --- | | Vendor | NVIDIA (https://github.com/NVIDIA/NeMo) | | Kind | Open-weight model | | Category | Speech-to-text (https://www.anchorterminal.com/categories/speech-to-text) | | Auth | None · The weights download from Hugging Face with no account, token or terms to accept. The repository is not gated (checked 2026-11-10). | | Pricing | Free (Free) · Free to download and use, commercial use included, under the NVIDIA Open Model License. Running it yourself costs little hardware, a 2.47 GB NeMo archive in FP32 (checked 2026-11-10). | | x402 | No · Weights you download and run yourself, so there is nothing to pay per call and no payment protocol (checked 2026-11-10). | | Licence | NVIDIA Open Model License | | Packages | huggingface: `nvidia/parakeet-unified-en-0.6b` | | Source | https://huggingface.co/nvidia/parakeet-unified-en-0.6b | | Docs | https://huggingface.co/nvidia/parakeet-unified-en-0.6b | | llms.txt | not found | | Last release | 2026-06-09 | | Surface graded | The open weights at huggingface.co/nvidia/parakeet-unified-en-0.6b, read from the model card, its safety, bias and privacy files, the file list and metadata, the commit history and the runtimes' own code at their latest releases on 10 November 2026. NVIDIA's licence terms and security pages were read for its other listings. Nothing was downloaded or run | | Model | A FastConformer encoder with 24 layers, trained jointly in offline and streaming modes, and an RNN-T decoder, 600M parameters per the card. The repository has no config for the Hub to count parameters from. Audio in, English text out with punctuation and capitalisation | | Languages | English only. The training data is about 250,000 hours of US English, and the card's bias file gives the validation data as 80% American and 10% British English | | Files | One NeMo archive, parakeet-unified-en-0.6b.nemo (2.47 GB, FP32), which holds a PyTorch checkpoint, a pickle format. No safetensors, no GGUF and no config.json. Hugging Face lists a SHA-256 for it | | Licence | The NVIDIA Open Model License, a custom licence that allows commercial use. The card says the model is ready for commercial and non-commercial use | | Runtimes | NVIDIA NeMo only (2.7.3 per the card), through ASRModel.from_pretrained and NeMo's chunked streaming script. Transformers 5.22.2 has Parakeet classes but the repository has no Transformers files, and vLLM, SGLang, llama.cpp, Ollama and LM Studio don't run it | | Input and output | Mono wav audio in. Output is a string of English text with punctuation and capitalisation, read from output[0].text. The card documents no timestamps. Streaming latency is the chunk plus the right context, from 2.08 s down to 0.16 s, with a 5.6 s left context | | Hardware | No memory figure on the card, which says the maximum audio length depends on GPU memory. Tested on NVIDIA V100, A100, A6000 and DGX Spark, on Linux | | Training data | Mostly the English part of NVIDIA's Granary dataset: YouTube-Commons (109,500 hours), YODAS2 (102,000), LibriLight (49,500) and Mosel (14,000), plus LibriSpeech, Fisher, Switchboard, WSJ, the National Speech Corpus, VCTK, VoxPopuli, Europarl-ASR, Multilingual LibriSpeech, Common Voice, People's Speech and AMI.

Confidence: low. Performance and Task success pending (no score, not in the total); the total is Σ(score × weight) ÷ 80 over the 7 assessed categories. "This run" is each category's share of the 100 points. | Category | Weight | This run | Score (0–100) | Points | | --- | --- | --- | --- | --- | | Capability | 35% | pending | pending | n/a | | Reach | 25% | 38.5 | 50 | 19.2 | | Risk | 20% | 30.8 | 35 | 10.8 | | Agent interface | 10% | 15.4 | 35 | 5.4 | | Documentation and upkeep | 10% | 15.4 | 79 | 12.2 | | Negative events | up to −15 | up to −15 | none recorded | 0 | | **Total** | | | | **47.5 → D** | ### Why each score - Capability: Pending for this listing. Nobody independent has published results for it in at least two areas yet, so its weight is shared across the other four and the total is capped at 61 until they do or our own runs start. - Reach 50 (checked 2026-11-10): Memory 30, the only build is the FP32 NeMo archive, 2.47 GB, and 2.47 GB × 1.2 = 3.0 GB, under 16 GB. Runtimes 0, none of the six runs it in a released version. Builds 0, NVIDIA publishes no quantised build of it. Terms 10, the NVIDIA Open Model License is a custom licence, not OSI-approved, that lets anyone use the model commercially for free under a use policy, which is the custom-licence band, as on NVIDIA's other listings. Download 10, the Hub API reports gated false on 10 November 2026, so the file downloads with no account and nothing to accept. Hosted 0, Hugging Face's inference provider mapping is empty on 10 November 2026, and the card names no NVIDIA API that serves it. 30 + 0 + 0 + 10 + 10 + 0 = 50. - Risk 35 (checked 2026-11-10): File safety 0, the only weights file is parakeet-unified-en-0.6b.nemo, a NeMo archive whose weights are a PyTorch checkpoint read with torch.load, a pickle format, and the card's documented path loads it. Provenance 15, the file sits in NVIDIA's own Hugging Face organisation, the one NVIDIA's NeMo repositories link to (10), and the Hub gives a SHA-256 for the archive and git hashes for the rest (5). Safety evaluation 0, no safety results on the card. Agent guidance 5, General cautions only. Licence risk 5, 15 less 5 for a use policy beyond the law (NVIDIA's Trustworthy AI terms and the guardrail clause) and 5 for terms the licensor can change or revoke, as read for NVIDIA's other listings under the same licence. Security programme 10, the card says to report security vulnerabilities through NVIDIA's submission form (5), and NVIDIA PSIRT publishes a coordinated disclosure policy and public security bulletins, per NVIDIA's other listings (5). 0 + 15 + 0 + 5 + 5 + 10 = 35. - Agent interface 35 (checked 2026-11-10): Chat template 0, no chat template and no prompt. Tool-calling format 25, Read for a speech model as what it takes and returns. Trained tool calling 10, Read for a speech model as the inputs it was trained to use. Structured output 0, Read for a speech model as typed outputs. Reasoning control 0, A speech recognition model with no reasoning. Context 0, no token context is stated. 0 + 25 + 10 + 0 + 0 + 0 = 35. - Documentation and upkeep 79 (checked 2026-11-10): Model card 14, Intended use, limitations (buffered streaming only, accuracy falling at 160 ms and below), architecture, parameters (600M) and the language are there. Training data 20, the card lists the training datasets by name, with hours for the four Granary subsets and about 250,000 hours in all, says how the transcripts were made, and NVIDIA publishes Granary on Hugging Face. Last change 10, the last commit to the repository, on 9 June 2026, edited the card, 154 days before this check and within 180. Responsiveness 20, All 5 discussions that aren't pull requests (8 April to 24 June 2026) have a reply from an NVIDIA member, counted on 10 November by author flags and dates with a script, text not read. Version policy 5, A first release of the unified model. File health 10, one archive and a card that agree on the model's name, size and NeMo as the way to load it. 14 + 20 + 10 + 20 + 5 + 10 = 79. Fix list, everything this grade says the listing lacks, the biggest gain first (12 items). What it covers is at https://www.anchorterminal.com/fixes/parakeet-unified-en-0-6b.md (JSON https://www.anchorterminal.com/fixes/parakeet-unified-en-0-6b.json). The whole list for a coding agent comes from `POST https://www.anchorterminal.com/api/v1/fix-list` with `{"listing": "parakeet-unified-en-0-6b", "plan": "read"}`, free while the beta runs ### What we couldn't check - File safety is 0 because the only weights are in a pickle format. The checklist's 15 band is for pickle files beside safer ones, and there are none here - Last change reads the repository's commits. The Parakeet TDT listing read NVIDIA's own runtime's code for that line, and no such runtime was checked for this model - Capability is pending because no independent results were looked up on the day. The card's results are on the Open ASR Leaderboard's datasets, run by NVIDIA - The gap list put it among the models that clear the October cut. Its own 30-day downloads are 8,455, so that rested on copies - unchecked on 10 November: NVIDIA's licence text and security pages, read for its other listings, the paper (arXiv 2604.19079) and whether NeMo's streaming script still matches the card ### Sources - model card: (seen 2026-11-10) - gating, dates, downloads, likes, file list and hashes: (seen 2026-11-10) - inference providers, none mapped: (seen 2026-11-10) - commit history: (seen 2026-11-10) - the card's safety file: (seen 2026-11-10) - the card's bias file: (seen 2026-11-10) - the card's privacy file, head read: (seen 2026-11-10) - discussions, replies counted by script from authors, dates and member flags: (seen 2026-11-10) - NVIDIA's Parakeet repositories: (seen 2026-11-10) - the NVIDIA Open Model License, read for NVIDIA's other listings: (seen 2026-11-10) - NVIDIA's vulnerability submission form, linked from the card: (seen 2026-11-10) - Transformers v5.22.2, the parakeet model directory (shallow clone): (seen 2026-11-10) - vLLM v0.33.0 registry, no Parakeet: (seen 2026-11-10) ## Score history Every move of a score since the listing was graded, newest first, with its cause.

Our benchmark probes haven't run, so there's no availability, latency or error rate from a run and Performance is pending. Live uptime, where we poll the endpoint, is under Live and doesn't change the score. No hosted version of these weights has a price on OpenRouter, so what a task costs is your own hardware and power. ## Strengths - One model for offline and streaming transcription, down to 160 ms of latency - Small: a 2.47 GB file that fits any machine - Training datasets listed by name with hours - NVIDIA replied in every discussion on the repository - A security reporting route and public bulletins from NVIDIA ## Weaknesses - The only file is a NeMo archive holding a pickle checkpoint - NVIDIA NeMo is the only runtime; none of the six we count runs it - No timestamps or other typed output documented - English only - A custom licence with a use policy that NVIDIA can change - No commit since 9 June 2026 ## Before you call it (notes for agents) 1. Load it with NeMo: `nemo_asr.models.ASRModel.from_pretrained(model_name='nvidia/parakeet-unified-en-0.6b')`, then `transcribe([path])[0].text` 2. Loading a .nemo archive unpickles a PyTorch checkpoint, so only load it from NVIDIA's repository 3. Send mono wav audio. English only 4. For live audio use NeMo's chunked RNN-T streaming script with a 5.6 s left context, and pick the chunk and right context from the card's table 5. Below 240 ms of latency accuracy drops, and at 80 ms NVIDIA recommends its nemotron-speech-streaming-en-0.6b instead 6. If you need word timestamps, use Parakeet TDT 0.6B v3 ## Get started Install: ```bash pip install -U "nemo_toolkit[asr]" python -c "import nemo.collections.asr as nemo_asr; m = nemo_asr.models.ASRModel.from_pretrained(model_name='nvidia/parakeet-unified-en-0.6b'); print(m.transcribe(['speech.wav'])[0].text)" ``` First request: ```bash # no HTTP server ships with it. For streaming, NeMo's script: python examples/asr/asr_chunked_inference/rnnt/speech_to_text_streaming_infer_rnnt.py \ pretrained_name=nvidia/parakeet-unified-en-0.6b dataset_manifest=manifest.json \ left_context_secs=5.6 chunk_secs=0.56 right_context_secs=0.56 att_context_size_as_chunk=true ``` ## Similar tools Ranked by shared capabilities, then score.

The badge or a plain link to this page verifies the listing, from a page on nvidia.com or one of its subdomains, or the front page of github.com/nvidia or of one of its repositories. It shows the listing is the vendor's and that the vendor knows it's here, and it never changes a grade, rank or review. The vendor sends the page's address to `POST https://www.anchorterminal.com/api/v1/verify` as `{"slug": "parakeet-unified-en-0-6b", "url": "…"}`, or calls the `verify_listing` tool at https://www.anchorterminal.com/mcp. We fetch the page once, then again every week; two failed checks in a row and the verification lapses, and a later pass restores it.
