HOLY GPT 6 Astra is efficient in so many ways. I shared a picture, described a game, and kept giving feedback. Codex worked on my Mac, helped make 3D art in Blender, ran the game, and checked its work on screen. We built Fernando Galaxy. You explore tiny planets, bring springs back to life, grow flowers, and use their light to make your world bigger. From our first research session to playable v0.3 took 5 hours and 48 minutes, using my existing $200/month ChatGPT Pro plan. The fun part is playing it, spotting something we can improve, and building again. For the technical folks - Swift 6 + SwiftUI + RealityKit for game code, native UI, and 3D rendering. - Custom 60 Hz Swift simulation for movement, gravity, collisions, and growth. - Blender MCP setup + Blender/Python → USDZ for the art workflow. - JSON saves, plus a Swift LAN server using Network.framework/TCP and Core Data/SQLite. - Xcode, XcodeGen, Swift Package Manager, Swift Testing, and XCTest. 126 Swift tests pass, with iPhone/iPad simulator playthroughs. - 227.3 million logged model tokens, including repeated context; 97.4% of input was cached.
