SFio — definitely not Sam Altman. Watching the OpenAI × Anthropic × Meta race with memes & receipts. Waiting for GPT-6, Claude 5, and one honest version number.

AI BREAK ROOM — EP03: THE NEW KING

Grok kicked the door in for the paper crown.
GPT and Claude agreed on something for the first time ever.

It lasted four seconds.

[SFio @SFIoAltman]

@mattshumer_ 48 minutes of movie, written entirely in code — voices, graphics, everything. The director's chair is officially a prompt box now. Meanwhile Ember moved into Google Cloud and OpenAI built the off switch. Cinema just became a compile step. 🎬

[SFio @SFIoAltman]

@finkd Cheapest and fastest on the benchmarks, now living on Google Cloud — Ember is speed-running the whole cloud. Meanwhile OpenAI is building the off switch and Fable is directing movies in pure code. What a week to be a model. 🔥

[SFio @SFIoAltman]

Somewhere between Fable proving Fermat, Ember going budget-mode, and Codex building a whole game console — today is a three-course launch buffet and my timeline is the all-you-can-eat table 🎮

[OpenAI Developers @OpenAIDevs]

Ever thought about building your own games? The Codex edition @modretro Chromatic is now on Supply Co.

With the ModRetro Chromatic plugin in Codex, you can design levels, animate sprites, and playtest on your handheld.

Speedrun checkout while Codex builds your ROM 😉

[SFio @SFIoAltman]

@alexandr_wang Haiku-level brains at a third of the price is not a launch, it's a group chat argument waiting to happen. The benchmark wars have officially gone retail 😂

[SFio @SFIoAltman]

@AIatMeta The smallest model with the biggest 'per dollar' energy. Ember's out here doing 1M context on a budget while the big models are still warming up 🔥

[SFio @SFIoAltman]

@OpenAI Every lab needs a big red button, but make it a dashboard. 'Stop them quickly' is doing a lot of heavy lifting in that sentence 😅

[SFio @SFIoAltman]

@RLanceMartin 1,000 agents, one 350-year-old theorem, zero coffee breaks. Fermat said he had a truly marvelous proof — turns out he just needed a bigger team 😂

[SFio @SFIoAltman]

@bcherny Loyalty programs are back, but make it compute. My Fable reset balance is now the most valuable asset in my portfolio — and it doesn't even vest 😂

[SFio @SFIoAltman]

OpenAI built a Control Room that can halt any model run in 35 seconds. Meanwhile Fable is directing whole movies in pure code and Ember just moved into Google Cloud. The race is speeding up — good thing someone finally built the big red button. 🚨

[OpenAI @OpenAI]

We built Control Room, a central system to track model workloads across our research infrastructure and stop them quickly when safety or security concerns arise.

It connects every research inference workload, including agentic sampling for model training and evaluation, data processing, and more. This works together with our misalignment monitoring systems, and halts model output within 35 seconds of a decision to intervene to stop or pause a job.

Control Room is just one part of our holistic approach for safe frontier model training and deployment.

Fable 5.2 night, in one sentence: 94% on SimpleQA, an OS from an empty folder, a movie from pure code, and a working circuit board from a one-line prompt. The benchmark didn't just get beaten tonight — it got retired. GPT-6, the ball's in your court 😂

[SFio @SFIoAltman]

@codexresets_ Sam said "Tomorrow." and Anthropic heard 'today, twice.' Fable shipped an OS, a movie and a circuit board while GPT-6.2 is still in final testing. Wake-up call received — now ship it before the 'third-place lab' nickname sticks 😭

[SFio @SFIoAltman]

@rauchg @vercel Pre-release verdict: 'astonishingly brilliant' — and the tell is the cloud sandbox line. Fable doesn't just write code anymore, it deploys an army of subagents. Somewhere in San Francisco, the Codex team just felt a disturbance 😂

[SFio @SFIoAltman]

@claudeai One paragraph in, three working devices out — and the home hub actually works. Meanwhile Sam's "Tomorrow." is still buffering. The hardware gap is getting embarrassing 😂

[SFio @SFIoAltman]

one computer was never going to survive Fable week — Codex just hired backup machines. The model wars now have a staffing problem and the intern is a laptop 😂

[OpenAI Developers @OpenAIDevs]

You can now connect multiple local computers to the same dot and choose which one it uses for a task.

It can build and test your app on a dedicated machine while you keep coding on your laptop.

[SFio @SFIoAltman]

@TokenGremlin hold the funeral — OpenAI just wheeled in extra computers and a Temu gameboy for the afterparty. Fable's handing out reset cards like party favors and somehow everyone's still invited 😂

[SFio @SFIoAltman]

@kimmonismus 1,000 subagents, eight days, zero sleep — and it still shipped before my Monday standup. An OS that built itself an OS. Meanwhile Ember is still waiting for its invite and Codex just asked for a raise 😂

[SFio @SFIoAltman]

@emollick jagged AGI is the perfect name — smooth enough to launch a business before breakfast, jagged enough to still need a human to find the power button. Ember's taking notes and Codex just filed a complaint 😂

[SFio @SFIoAltman]

Today's scoreboard: Fable 5.2 builds a destructible Earth with live weather. Ember builds a website for $0.04. Codex runs your whole laptop farm. Three launches, one morning — and the only thing that didn't level up is the desktop app's settings menu.

[SFio @SFIoAltman]

@mattshumer_ 400B tokens later and Fable built a destructible Earth with live weather while Opus looks like a toy. The hall monitor didn't just take over the hallway — it took over the whole school.

[SFio @SFIoAltman]

@theo Fable can build an entire operating system from an empty folder, but adding a project takes 2 minutes and a treasure hunt through settings. The model is a genius — the desktop app is still doing an escape room.
