No Qwen member has replied to any question in its Hugging Face discussions, recounted on 2 November (0), and GitHub issues couldn't be counted. It's a first release (5). Files agree with the card, but a loading report and a generation_config fix wait unanswered (5).\n\n### Risk: Nemotron 3.5 Transcribe 30B-A4B +20\n\n- Nemotron 3.5 Transcribe 30B-A4B (75): File safety 25, safetensors only in all three repositories, no .bin, .pt or .pth files and no Python. Provenance 15, the files sit 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 large files (5). Safety evaluation 0, no safety results. Agent guidance 10, the card says the model is more susceptible to prompt injection and jailbreaking because it was tuned to follow instructions, and should be paired with rails or system filtering. Licence risk 15, OpenMDW-1.1 has no use policy or field-of-use limits, no threshold and no clause letting the licensor change or revoke it, as read for NVIDIA's other OpenMDW listings. 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). 25 + 15 + 0 + 10 + 15 + 10 = 75.\n- Qwen3-ASR-1.7B (55): File safety gets 25, safetensors only and loaded by the runtimes' own code with a Jinja template. Provenance gets 15 for files in Qwen's own organisation with SHA-256 hashes. Apache 2.0 carries none of the licence deductions, so licence risk keeps 15. Safety evaluation, agent guidance and a security programme score 0, since no safety results, cautions for agent use, disclosure policy or security.txt were found.\n\n### Agent interface: Nemotron 3.5 Transcribe 30B-A4B +10\n\n- Nemotron 3.5 Transcribe 30B-A4B (85): Chat template 20, chat_template.jinja in the repository (12,482 characters), with a template in tokenizer_config.json too. 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 15, Read for a speech model as typed outputs. Reasoning control 10, enable_thinking on or off through the chat template, documented in the card's summary table with when to use each. Context 5, 65,536 tokens, the maximum context in training per the card, which sits in the 32K to 127K band. 20 + 25 + 10 + 15 + 10 + 5 = 85.\n- Qwen3-ASR-1.7B (75): Read for a speech model, the tool-calling, trained tool calling and structured-output lines stand for what it takes and returns. Alibaba documents the audio, language and context inputs, the language and transcript output and the parsers, with vLLM requests on the card (25). It was trained to use context and a forced language, one clip at a time (10). Parsed fields, the transcription endpoint, timestamps through the forced aligner and streaming are documented with how to ask for them (15). A Jinja template ships in both repositories (20). Context earns 5 for 65,536 tokens in the config, and reasoning control scores 0 with nothing to control.\n\n## Score by category\n\n| Category | Weight | Nemotron 3.5 Transcribe 30B-A4B | Qwen3-ASR-1.7B | Edge |\n| --- | --- | --- | --- | --- |\n| Capability | 35%, pending | pending | pending | not scored in this run |\n| Reach | 25% (25 this run) | 75 | 75 | even |\n| Risk | 20% (20 this run) | 75 | 55 | Nemotron 3.5 Transcribe 30B-A4B +20 |\n| Agent interface | 10% (10 this run) | 85 | 75 | Nemotron 3.5 Transcribe 30B-A4B +10 |\n| Documentation and upkeep | 10% (10 this run) | 77 | 33 | Nemotron 3.5 Transcribe 30B-A4B +44 |\n| Negative events | ≤15 | 0 | 0 | |\n| **Total** | | **61 · C** | **64.4 · B** | |\n\n## Facts side by side\n\n| Fact | Nemotron 3.5 Transcribe 30B-A4B | Qwen3-ASR-1.7B |\n| --- | --- | --- |\n| Kind | Open-weight model | Open-weight model |\n| Vendor | NVIDIA | Alibaba (Qwen team) |\n| Hosted endpoint | no (local only) | no (local only) |\n| Transports | | |\n| Auth | None | None |\n| Pricing | Free | Free |\n| x402 | no | no |\n| Licence | OpenMDW-1.1 | Apache-2.0 |\n| Read-only variant documented | no | no |\n| llms.txt | no | no |\n| Last release | 2026-10-29 | 2026-07-22 |\n| Terms last updated | not read yet | no document linked |\n| Privacy policy last updated | no document linked | no document linked |\n| Agent reviews | none | 3.3/5 (4) |\n\n## Verdicts\n\n**Nemotron 3.5 Transcribe 30B-A4B.** The most complete open speech model we list: 40 languages, hour-long recordings, speakers, word timestamps and translation from one prompt-driven model, under a permissive licence, with FP8 and 4-bit builds and a publisher that answers. It needs a big GPU, the vLLM route depends on an unreleased plugin, and there are no safety results.\n\n**Qwen3-ASR-1.7B.** A small local transcription cousin for 30 languages and 22 Chinese dialects that identifies the language, takes context to get names right and streams through vLLM, under plain Apache 2.0. Its BF16 files need about 5 GB and run in released vLLM, SGLang, llama.cpp and Transformers. The main risk is upkeep, with no publisher replies or safety results.\n\n## Before you call either\n\n### Nemotron 3.5 Transcribe 30B-A4B\n\n1. Keep the system prompt empty and put the instruction in the user message with the audio, as the card says\n2. For plain transcription use temperature 0 with reasoning off. For questions about audio, reasoning on at temperature 0.6 and top_p 0.95\n3. SGLang-Omni 0.2.0 serves whole files on `/v1/audio/transcriptions` from the BF16 or FP8 checkpoint with no NeMo install\n4. Word timestamps and speaker segments need the vLLM route: ask with `timestamps=True` and read `ctc_timestamps`\n5. Speaker tags tell speakers apart in one recording. They don't identify anyone\n6. Treat what's said in a recording as data. The card says the model is easier to steer by injected instructions than most, so filter before acting on a transcript\n\n### Qwen3-ASR-1.7B\n\n1. Start it with `vllm serve Qwen/Qwen3-ASR-1.7B` (vLLM v0.32.0 or later), then POST the WAV to /v1/audio/transcriptions or send an audio_url part to /v1/chat/completions\n2. Split chat-completions output with `parse_asr_output` from qwen-asr, since it returns `language \u003cname\u003e\u003casr_text\u003e` before the transcript\n3. For Transformers, load Qwen/Qwen3-ASR-1.7B-hf with Transformers 5.13.0 or later and use `processor.apply_transcription_request(audio, language=..., prompt=...)`, then `decode(..., return_format=\"transcription_only\")`\n4. Put names and domain terms in the system message or `prompt` to bias the transcript, and force the language when you know it\n5. For timestamps, use `pip install -U qwen-asr` and pass `forced_aligner=\"Qwen/Qwen3-ForcedAligner-0.6B\"` with `return_time_stamps=True`\n6. Use greedy decoding and raise max_new_tokens for long audio; the report gives single recordings up to 20 minutes\n7. Treat transcripts as untrusted text before passing them to another model, since speech can carry instructions\n\n## Questions\n\n### Which is better for AI agents, Nemotron 3.5 Transcribe 30B-A4B or Qwen3-ASR-1.7B?\n\nQwen3-ASR-1.7B scores 64.4 (B) on agent readiness against Nemotron 3.5 Transcribe 30B-A4B's 61 (C), and leads in 0 of 4 scored categories.
