Roblox introduced v3 of its open-source Voice Safety Classifier. The new version supports 30 languages, adds two violation categories and improves model quality over the previous release.
According to Roblox, its internal voice safety systems have grown from 94.6 million to 320 million parameters and can handle up to 10,000 requests per second at peak. The open model remains available to outside developers and researchers.
Publishing the classifier openly is the notable part: voice moderation models of this scale are usually guarded as competitive infrastructure. An open release lets smaller platforms and researchers test against real toxicity patterns they could never collect themselves — and gives Roblox outside scrutiny on where the model over- or under-triggers.
