  OpenAI may be about to change how we use ChatGPT forever. According to a new leak spotted by TestingCatalog, the company appears to be preparing an always-on AI agent codenamed "O" — and it could be announced as soon as DevDay on September 29. What the leak reveals References to "O" were found scattered across ChatGPT's configuration files, including "O" as a display name and an email suffix configured as "-o". That suffix is the interesting part: it suggests the agent would ship with its own email identity from day one, able to send and receive mail on your behalf. On top of that, "O" briefly appeared as a listed benefit on the ChatGPT upgrade page for the $100 Pro plan before disappearing — the classic accidental leak. A persistent agent Put together, the clues point to a persistent agent: software designed to keep working outside a normal chat session.

Meta Just Turned Your Phone Into a Game Studio — AI Games From Text Prompts

Have you ever had a game idea pop into your head and wished you could just… make it? No coding, no game engine, no months of work. At its Connect conference on September 24, Meta made that real: two new AI tools that turn a plain-English description into a playable 2D or 3D game.

Horizon Create: describe it, play it

Horizon Create is a standalone mobile app. You describe the game you want in your own words (or start from a ready-made template), and Meta's Horizon Engine — the same engine behind its Horizon social worlds — builds a complete game around it. The agentic engine handles game mechanics, difficulty balancing, art direction, progression systems, and even multiplayer support. You then keep talking to it, refining characters, art style, story, and progression by describing what you want changed.

How the flow works

The flow is designed to feel natural: describe your idea, play the generated build, request changes, repeat. The game generates in the background while you play other titles, and the app pings you when your build is ready to playtest. You can run multiple projects at once.

Horizon Studio: the deep-editing workspace

For deeper editing there's Horizon Studio, a browser-based workspace with visual controls — arrange scenes, swap assets, fine-tune scripts and lighting, and keep using text prompts for big revisions. Projects sync between your phone and the web, so you can sketch an idea on your phone and polish it on your laptop later.

Publish straight to the feed

Here's the part that matters most: when your game is done, you publish it straight into Facebook, Instagram, and Horizon feeds. Someone scrolling Instagram can tap a clip of your game and be in a multiplayer session within seconds — no download, no app store. Meta says built-in safeguards automatically apply age ratings and content filters before a game goes live.

Why it matters

Why does this matter? Game development has always been a gated community: months of work, specialized skills, expensive hardware, and then the brutal challenge of finding your first players. Meta is trying to collapse both the making and the marketing into one pipeline that lives on its own platforms. The tools are still rolling out gradually through an open waitlist, so it's too early to judge how good the AI-built games really feel — and Meta hasn't spelled out how creators will make money yet. But the direction is clear: the same "describe it and it's built" shift that hit writing and images has now reached games. If you've ever said "someone should make a game where…", that someone might soon be you.
