Well I know the first thing I’m doing when fable access is restored 👀

[Unreal Engine @UnrealEngine]

Drive characters’ bodies, faces, and more from regular video with the MetaHuman Animator Markerless Motion Capture plugin on @Fab. No suits or markers needed!: https://t.co/ORDT5F6uzn

I asked Claude Fable 5 to reverse engineer a 1993 DOS game with no source code.

It read the raw machine code, rewrote the engine in C, and gave me a fully editable port for every platform.

30 min from EXE to iPhone.

Sharing it all so you can revive your own childhood games!

[Peter Steinberger 🦞 @steipete]

How am I only now finding out about appshots?

I was dragging screenshots into codex live a caveman.

[Anshu @anshuc]

Wow, if you connect Fable to image-gen and image-to-3D APIs, it's *insane* for game dev.

It made an infinite explorable universe, with characters and lore. All assets and sound completely from scratch.

A French engineer who lives quietly in Paris has spent 30 years writing software that the entire internet now runs on without knowing his name.

He wrote the code that streams every YouTube video, every Netflix show, every TikTok clip. He wrote the code that runs the virtual servers underneath AWS, Google Cloud, and Microsoft Azure. He calculated more digits of pi than anyone in history. He has no Twitter. He has no marketing. He just keeps shipping.

His name is Fabrice Bellard.

Here is the story, because almost nobody outside the systems programming world knows what one man has built.

Fabrice was born in 1972 in Grenoble, France. He studied at École Polytechnique, the top French engineering school. He never went to Silicon Valley. He never built a startup empire. He just wrote code.

In 2000 he started a project called FFmpeg, an open-source multimedia framework for encoding, decoding, and streaming video. He was 28. The project did one thing nobody else had done well. It handled every video and audio format that existed, in one library, on every operating system. He led it himself for years.

Today FFmpeg is the invisible engine of the internet. YouTube uses it. Netflix uses it. VLC uses it. Chrome and Firefox use parts of it. Every Android phone, every iPhone, every smart TV, every video editing tool you have ever touched runs FFmpeg somewhere underneath. If you have watched a video on a screen in the last 20 years, Fabrice's code processed it.

He was not done.

In 2003 he started QEMU, a machine emulator and virtualizer. He wrote it solo until version 0.7.1 in 2005. QEMU lets you run any operating system on any other operating system. It became the foundation of modern virtualization. KVM, the Linux kernel hypervisor, runs on top of QEMU. Every major cloud provider, AWS, Google Cloud, Microsoft Azure, IBM Cloud, runs virtual machines on infrastructure built around it. The Quick Emulator is the most cited piece of cloud infrastructure code on Earth.

He kept going.

In 2001 he won the International Obfuscated C Code Contest with a small C compiler that grew into TCC, the Tiny C Compiler. TCC can compile and boot a Linux kernel from source in under 15 seconds. In 2004 he calculated the most digits of pi ever computed at the time, using a personal desktop computer and an algorithm he derived himself called Bellard's formula. In 2011 he wrote a complete PC emulator in pure JavaScript that runs Linux in your browser, a project called JSLinux that engineers still cannot believe is real.

In 2019 he released QuickJS, a small but complete JavaScript engine that fits where V8 cannot. In 2021 he released NNCP, a neural network based lossless data compressor that immediately took the lead on the Large Text Compression Benchmark.

Then he turned his attention to large language models. He built TextSynth Server, a web server with a REST API for running LLMs locally. He released ts_zip and ts_sms, compression utilities that use language models to compress text and short messages at ratios traditional algorithms cannot reach. He released TSAC, a very low bitrate audio compression system. In December 2025 he released Micro QuickJS, a new JavaScript engine for microcontrollers, separate from QuickJS, designed for environments with almost no memory.

Fabrice co-founded a telecom company called Amarisoft in 2012, where he serves as CTO. Amarisoft builds 4G and 5G base station software used by carriers and labs around the world. He has been running it for over a decade while continuing to ship personal projects from his own home page at bellard dot org

He has no Twitter. He has no Instagram. He gives almost no interviews. His personal website is a flat list of projects with no styling, no fonts, no marketing copy. Just titles and links.

A quiet French engineer who never moved to Silicon Valley wrote the code that quietly runs the internet.

He is still shipping.

[How To Prompt @HowToPrompt__]

Apple just did something nobody expected.

They turned 2 billion iPhones into local AI machines.

They open-sourced coreai-models, the entire toolkit that lets you export any HuggingFace model and run it natively on iPhone, iPad and Mac with zero cloud.

→ Runs 100% on the Neural Engine
→ No cloud. No API keys. No subscriptions.
→ Fully offline. Your data never leaves the device.

It even ships with skills for Claude Code, Codex, and Gemini, so your coding agent already knows how to use it.

100% Open Source.

[Google Cloud Tech @GoogleCloudTech]

ICYMI: We launched Data Agent Kit, a unified, open-source collection of data engineering and data science skills, tools, and plugins that integrate into the environments practitioners already use—VS Code, Claude Code, Codex, Antigravity CLI, and more → https://t.co/kqGqvrHImc

[Josh Daws @JoshDaws]

Claude Fable just built this entire product from one prompt. I'm blown away.

Shotblock is a 3D shot-planning tool for AI filmmakers — real lens math, actor blocking, 180 ° rule warnings, animatics, storyboard + prompt export. It researched storyboard conventions, wrote its own test suite, verified everything in a browser, and deployed it.

Then I asked for a promo video. It scripted, recorded, and edited the one below with minimal direction.

Give it a try. Free, no signup. Feedback button in the app for any issues or feature requests.

[〽️att Greenberg @McGreenBeats]

Fable one shotted the game logic.
GPT Image 2 for designs.
Blender MCP for models + lighting.

Total dev time ~6 hours.

[NotebookLM @NotebookLM]

Ok, it’s probably about time we changed the game.

Stay tuned 👀

[Fortnite Developers @FNCreate]

Build worlds. Build bonds.

[Guinness Chen @guinnesschen]

One of my many codex pets

[Google Gemma @googlegemma]

Introducing Magenta RealTime 2, a new open model musicians can play as an instrument!

Run low-latency, live music synthesis natively on your MacBook using MIDI, text, and audio. 🎶

We love seeing Google’s open model ecosystem grow!

[Bilawal Sidhu @bilawalsidhu]

Well that escalated quickly 😂

Insane camera path generation harry!

[OpenAI Developers @OpenAIDevs]

More of the iOS app loop, now inside Codex.

The Build iOS Apps plugin lets Codex view and test your iOS app in the in-app browser, open SwiftUI previews, and hot reload edits without leaving Codex.

[OpenAI Developers @OpenAIDevs]

The votes are in.

@isausmanov’s Agentic OS for a Phone is the Voice Hack Night People’s Choice winner.

A voice-first mobile OS. Users talk, agents answer and take action across the phone.

Congrats to the team on taking home $50,000 in API credits.

[OpenClaw🦞 @openclaw]

We are proud to continue our collaboration with @nvidia with support for thier NVIDIA RTX Spark Laptop. Strengthening our support to support OpenShell and @Microsoft Security Primitives.
Building ontop of our earlier work with NemoClaw and our existing fully-native Windows support.

[Logan Kilpatrick @OfficialLoganK]

We just shipped the ability to build apps that connect to Gmail, Drive, Sheets, and more directly inside of @GoogleAIStudio, no navigating to other sites, you can add testers right inside of AI Studio, with full public sharing coming soon!!
