SAVRN's Notes on audiobox-aesthetics
When a pipeline produces or ingests audio at volume and someone needs a score for how each clip sounds, this 104M-parameter model from AI at Meta returns one across speech, music and sound in a single pass. It is small enough to disappear into a rack: 0.2 GB of weights and 0.2 GB of memory at 16-bit, so the cheapest Index option, one MI300X with 192 GB at $1.85 an hour, is priced for the generator beside it, not for this. The repository is 6 files and 831 MB, safetensors only, and the code wants Python 3.9 and PyTorch 2.2 or newer.
CC BY 4.0 permits commercial use and adaptation with two obligations: credit the creator and state what you changed. Read the paper it is described by, arXiv:2502.05139, because the page lists no architecture, library or reported evaluations. Last update was March 4, 2025, so treat it as fixed.
SAVRN's Notes on clap-htsat-fused
Pairing sound with text is the job here: LAION eV's clap-htsat-fused puts audio and text embeddings in one space, so it can classify audio zero-shot against labels you write or produce features for search. Training data was LAION-audio-630k; size is 154M parameters. At 16-bit the weights are 0.3 GB and the run needs 0.4 GB; the cheapest listed option is one 192 GB MI300X at $1.85 an hour on-demand. Treat it as a sidecar on a card that is already serving something larger.
Apache 2.0 covers commercial deployment, modification and redistribution if the notices and any NOTICE file stay attached and significant changes are stated. Two checks before committing. The text side stops at 514 tokens, fine for labels and captions, not for long documents. And the repository is 1.23 GB in 11 files at float32 against 0.3 GB of 16-bit weights, so budget for storage and conversion.
