## Runs On

What it takes to serve VibeVoice-ASR (8.7B parameters): the memory its weights need at each precision, and the cheapest way to rent enough data-center GPUs to hold them.

Memory is the weights at that precision plus 20% for the runtime and a short context; a long context needs more. Prices are the lowest on-demand hourly rates in the [SAVRN Index](https://savrn.com/ai-index/pricing/gpus), read Oct 24, 2026.

## SAVRN's Notes on VibeVoice-ASR

If you need who said what and when from a long recording, this is the model we would size first. VibeVoice-ASR takes up to 60 minutes of continuous audio in a single pass inside a 64K token length and returns speaker, timestamp and content together, with custom hotwords and more than 50 languages. The 8.7 billion parameters weigh 17.3 GB at 16-bit and need 20.8 GB of memory, which fits one MI300X with 192 GB at $1.85 an hour; 8-bit needs 10.4 GB and 4-bit 5.2 GB. The rest of the card is headroom for parallel streams.

MIT is the license, dated 2026-01-21 from Microsoft, which clears commercial transcription products, changes and redistribution as long as the notice travels with the files. Before committing, note that the page lists no context length, so the publisher's 60-minute, 64K token figure is your ceiling, and that no SAVRN Index host prices it, so plan on your own card.

## Questions About VibeVoice-ASR

### How much GPU memory does VibeVoice-ASR need?

About 20.8 GB at 16-bit and 5.2 GB at 4-bit: the weights (8.7B parameters) plus a working margin. A long context needs more.

### What is the cheapest GPU to run VibeVoice-ASR on?

At 16-bit, 1x MI300X from $1.85 an hour; at 4-bit, 1x MI300X from $1.85 an hour, at the lowest on-demand prices the SAVRN Index lists.

### Can I use VibeVoice-ASR commercially?

Yes. VibeVoice-ASR is released under MIT License. The MIT License is a short permissive license. It permits commercial use, modification and redistribution, provided the copyright notice and permission notice are included.

[Mistral AI_](https://savrn.com/model-publishers/mistralai)

Voxtral Mini 4B Realtime 2602 is a multilingual, realtime speech-transcription model and among the first open-source solutions to achieve accuracy comparable to offline systems with a delay of = 3600 / 0.8 = 45000. In theory, you should be able to record with no limit; in practice, pre-allocations of RoPE parameters among other things limits --max-model-len. For the best user experience, we recommend to simply instantiate vLLM with the default parameters which will automatically set a maximum model length of 131072 (~ca. 3h).

Audio8 ASR Infinite is a native streaming speech recognition model built to be as responsive as possible. It offers a selectable audio clock (80/120/160 ms) and a transcription delay (240–560 ms). With our adapted vLLM build it transcribes unlimited-length audio 24/7 without drifting. - Super responsive — the native streaming architecture decodes 12.5 times per second. - Unlimited-length transcription — a rolling KV Cache keeps both memory and latency constant, even in 24/7 operation. - Selectable streaming clock — one text token per clock step (12.5 / 8.3 / 6.25 decisions per second), balancing perception granularity and resource cost. - Configurable transcription delay — set how much…

### [Qwen3-ASR-1.7B](https://savrn.com/models/qwen3-asr-1-7b)

[Qwen](https://savrn.com/model-publishers/qwen)

The Qwen3-ASR family includes Qwen3-ASR-1.7B and Qwen3-ASR-0.6B, which support language identification and ASR for 52 languages and dialects. Both leverage large-scale speech training data and the strong audio understanding capability of their foundation model, Qwen3-Omni. Experiments show that the 1.7B version achieves state-of-the-art performance among open-source ASR models and is competitive with the strongest proprietary commercial APIs. Here are the main features: Novel and strong forced alignment Solution: We introduce Qwen3-ForcedAligner-0.6B, which supports timestamp prediction for arbitrary units within up to 5 minutes of speech in 11 languages. Evaluations show its timestamp…
