Evidence AddedView practice →Roblox deployed a multilayered AI content moderation system—built over approximately five years—that automatically detects policy-violating text, images, 3D objects, and, as of early 2026, entire in-game scenes in real time at a scale of over 750,000 requests per second across 28 languages. The system operates across all user-generated content on the platform.
Roblox's moderation infrastructure uses large transformer-based machine learning models optimized through distillation and quantization to classify text, images, voice, and 3D assets for policy violations in milliseconds. In March 2026, Roblox launched a new real-time multimodal moderation system that evaluates entire in-game scenes—including avatars, text, and 3D objects together—to catch content that passes individual item checks but is problematic in combination (e.g., an offensive drawing combined with an avatar). As of early 2026, the system is shutting down approximately 5,000 servers per day for violations and is targeting 100% playtime monitoring. Roblox states that AI is deployed for moderation only when it outperforms humans in both precision and recall at scale, with human moderators retained for nuanced cases, complex investigations, and appeals.

Roblox offers an AI assistant built into Roblox Studio that helps game developers write code, plan experiences, generate 3D assets, and test games using plain-language prompts. The assistant, upgraded in April 2026 with agentic features including Planning Mode and automated playtesting, acts as a multi-step collaborative development partner for the platform's creator community.
The Assistant (previously anchored by Code Assist, which reached full general release in February 2024) accepts natural-language prompts and produces Luau script code, 3D mesh objects via the Cube 3D Mesh Generation API, and structured game-design action plans. The April 2026 'agentic' upgrade added Planning Mode—which analyzes a game's existing code and data model, asks clarifying questions, and generates an editable action plan—plus a playtesting agent that reads output logs, captures screenshots, and simulates keyboard/mouse inputs to identify bugs and feed corrections back into the planning loop. Roblox also announced integration of the Model Context Protocol (MCP) so creators can connect external tools like Claude, Cursor, and Codex with Studio.
Roblox deployed real-time AI text chat translation in February 2024, automatically translating in-game chat messages across 16 languages so players worldwide can communicate without sharing a common language. The feature is built on Roblox's proprietary multilingual large language model and is available by default in all Roblox experiences using the platform's TextChatService.
The system uses a custom unified transformer-based large language model trained to translate between any combination of Roblox's 16 supported languages in a single model, rather than maintaining 256 separate translation models for each language pair. Translations are displayed with approximately 100 milliseconds of latency, making them nearly invisible during gameplay. The model was trained on open-source data, Roblox's own in-experience translation data, human-labeled chat results, and common chat phrases, and was fine-tuned to understand Roblox-specific slang (e.g., 'obby,' 'afk'). Users can toggle off automatic translation or click an icon to see the original untranslated message. Roblox has announced plans to extend the model to real-time voice chat translation, starting with English, Spanish, French, and German.
