Roblox announced agentic upgrades to its Studio AI assistant, adding a Planning Mode that analyzes a game's code and data model to produce editable multi-step plans, Procedural Model Generation for code-driven 3D asset placement, and a beta Testing Agent that simulates player behavior and feeds results back into planning loops. The company says 44% of its top 1,000 creators already use Roblox Assistant or third-party AI tools via MCP. Future roadmap items include parallel agent execution and cloud-based long-running workflows.
