Roblox Studio re-centers AI as nearly half of top creators use it

Roblox says 44% of its top 1,000 creators use Roblox Assistant or third-party AI through MCP, and the company is rolling out agent-style Planning, Mesh and Procedural Model tools and a Playtesting Agent to make AI central to Studio.

Roblox is expanding AI features across Roblox Studio and Assistant to move AI from a peripheral tool to a core part of the development loop. The company reports that 44% of the top 1,000 creators are already using Roblox Assistant or third-party AI tools via MCP to plan, build, and test games. New features include an agentic Planning mode, asset-generation tools, and a Playtesting Agent beta. Roblox also plans a built-in MCP server and says cross-session memory will arrive shortly after launch. Key details: - Roblox reports 44% of the top 1,000 creators use Roblox Assistant or third-party AI tools through MCP to support game development. - The updated Planning mode analyzes a game's code and data model, asks clarifying questions, and produces an editable action plan that agents can reference. - Mesh Generation and Procedural Models enable creators to drop textured meshes and generate modular assets from text or image prompts, with editable attributes. - The Playtesting Agent beta runs tests against the plan, examines logs, and can use the player character for automated QA. - Roblox is adding a built-in MCP server to open Studio to third-party AI tools, and a cross-session memory feature is expected shortly after launch. Summary: The company is restructuring Studio to let AI participate across planning, building, and testing rather than as a one-off tool. Given existing creator uptake, Roblox frames these additions as a step toward agent-driven workflows. Cross-session memory is scheduled after launch; broader impacts on development practices are undetermined at this time.
