Unreal teams wanting an in-editor agent for Blueprints, C++ and levels
What it does
OpenAI's general-purpose assistant: chat, image creation and Codex coding help on the web, desktop and mobile; usable for concept images, placeholder art and gameplay code.
AI toolkit that runs inside the Unreal Engine editor: an agent that understands your project's Blueprints, C++, assets and levels and can answer questions and make edits.
Verdict
For concept images and coding help on one subscription; OpenAI's terms assign Output to you on every plan, including Free, but similar output can go to other users.
For Unreal devs who want a project-aware assistant in the editor; it has no free credits beyond a 14-day trial, and its output licence is unverified.
