An evaluation row appears only where at least two of these models report the same benchmark with the same stated configuration, metric, unit and setup. Different evaluators stay named in each cell. Values are shown as reported: no unit conversion, no ranking.
Other Reported Results
These results are listed for each model on its own, because the conditions needed to compare them are not stated or do not match. Two results that leave a condition blank are not assumed to share it.

SAVRN's Notes on whisper-large-v3-turbo
The lineage explains the size. This speech recognition build descends from openai/whisper-large-v3, pruned and fine-tuned with the decoding layers cut from 32 to 4, and lands at 809M parameters needing 1.9 GB at 16-bit, 1.0 GB at 8-bit or 0.5 GB at 4-bit. Against the cheapest listed rental, one 192 GB MI300X at $1.85 an hour, the design question we ask is how many audio streams to stack on one card, not whether it fits.
MIT asks for almost nothing: keep the copyright and permission notices, and commercial use, modification and redistribution are all yours. The reported evaluations are third-party figures and uneven by source, a mean word error rate of 7.83 with 2.1 on LibriSpeech clean and 16.13 on AMI, so pick the row that sounds like your audio. No context length is listed, so the audio window is a question for the publisher's documentation.
