Frequently asked questions about Bigvgan_v2_44khz_128band_512x
Answered from the entry's own fields: context, license, modalities, evidence, serving and the memory to self-host.
NVIDIA has not published a context window for Bigvgan_v2_44khz_128band_512x, so the catalog shows it as not available rather than estimating one.
Yes. Bigvgan_v2_44khz_128band_512x is an open-weight model released under the MIT license, so the weights can be downloaded and self-hosted within that license's terms.
Bigvgan_v2_44khz_128band_512x accepts Audio and produces Audio. The capabilities card on this page lists which API features each deployment honours, such as function calling and structured output, with the source each was checked against.
No published benchmark result for Bigvgan_v2_44khz_128band_512x is in the catalog yet, so the model is shown as unmeasured. It is not ranked or estimated; the router treats it as unknown for every task until a suite measures it.
Not on the managed pool today; Bigvgan_v2_44khz_128band_512x is listed for reference and comparison. Connect your own provider key or endpoint that serves it and the gateway runs it on your account, with routing decisions recorded the same way.
NVIDIA has not published a parameter count for Bigvgan_v2_44khz_128band_512x, so the catalog cannot estimate its memory footprint. The capacity planner can size it from a parameter count you supply.
