GPT-6 Luna is the new Economy model

Economy builds now run on GPT-6 Luna. On the customer tasks we tested side by side, it completed more of what we asked than Gemini 3 Flash and used far fewer credits, so the same credits go further. It is not in a hurry: a build can take longer than you are used to.

• Your saved choice moves with it. If you had picked Gemini 3 Flash as your Economy model, that pick now points at GPT-6 Luna.
• Economy has one model now. Its card shows GPT-6 Luna and no longer opens a list of models. Standard and Ultra still let you pick a model.
• The summaries that keep long chats going now run on GPT-6 Luna too.
