GPT-6 Astra Independently Builds a Puzzle, Supply-Chain Model, and Booklet Tool

OpenAI's GPT-6 Astra ran three independent AI-agent experiments, published on 4 September, in which separate agents built a string-based puzzle game called Loose End, a supply-chain simulation called The Order Echo, and a single-sheet booklet layout tool called Pocket Press. Each project went through a structured prototype review process before refinement, with a coordinating agent identifying and flagging issues for builders to correct. In Loose End, a logic puzzle involving a finite string, pegs, and bells, an early input bug ignoring brief keypresses was caught and fixed before the game was finalised. The Order Echo models how different ordering policies affect a four-tier supply chain, with its interface allowing users to inspect weekly demand and order arithmetic on a shared scale. Pocket Press arranges an eight-page booklet onto a single A4 or US Letter sheet and, following reviewer feedback, gained discoverable save options, folding instructions, and the ability to reload editable source files.
