Two GPT-5.6 Coding Demos: A Block World and a Spreadsheet

RESUMEN

En 30 segundos

Matthew Berman briefly demonstrates a block-based game and a spreadsheet application from his GPT-5.6 testing. He says Codex inspected the desktop Excel application while building the spreadsheet over six days. The clip shows selected interactions but does not independently establish complete Excel compatibility or production readiness.

A block-based game

Berman shows a game created during GPT-5.6 testing.

Matthew Berman says he spent over a month testing GPT-5.6 and shows a Minecraft-like block world. He walks through the scene, points out moving shadows and a block-breaking animation, and opens an inventory. The short clip demonstrates selected features rather than evaluating the whole game.

DIAPOSITIVA 1 / 2Block-world gameplayThe demo shows the block environment and inventory.

A spreadsheet application

He describes the agent's development process and shows selected spreadsheet functions.

Berman also presents an Excel-like application. He says Codex with GPT-5.6 inspected the actual Excel desktop interface, clicked controls and used the observations while building the clone. He stopped the process after six days, saying it would otherwise have continued adding features.

He demonstrates a cell formula and says he created a pivot table, describing the application as publicly hosted. The short does not test all spreadsheet functions, compatibility or reliability; his broad comparison with Excel is a claim rather than an independently verified result.
