Roblox open-sources three safety models through ROOST

Summary

Roblox announced plans to contribute three open-source safety models to the Robust Open Online Safety Tools (ROOST) Model Community. The company joined ROOST as a founding member alongside Google, OpenAI, and others in early 2025. The new safety models include updates to Roblox's open-source PII Classifier, Roblox Sentinel, and its latest voice safety classifier. These models are designed to help online platforms identify and filter personally identifiable information, detect harmful behavior, and enhance voice chat safety. Roblox's move highlights the gaming industry's growing focus on online safety, and by open-sourcing these tools, other platforms and developers can leverage them to protect users. For players, this means safer gaming environments; for the industry, it fosters collaboration and standardization in safety technology.
