Viral score

Based on absolute engagement — the platform doesn’t expose follower counts here, so large accounts score higher.

From likes, comments.

Why it worked

Uses short lines and white space, which makes a long post feel quick to read.
Ends on a short line that is easy to quote and repeat.
Short enough to read in full without expanding, which removes a step before the point lands.

The mechanics

Hook: Plain observation
Structure: Hook → Landing
Style: Short lines with heavy white space, built to be scanned.
Tone: punchy
Written for: Engineers and technical teams

For those confused why the US state and Silicon Valley are having a meltdown on twitter today. China released multiple AI models that are 50x more efficient than the best American AI models and made them open source, ruining the AI market

FFmpeg is moving to Rust 🦀 Our use of C and Assembly in FFmpeg has been an unacceptable violation of safety. FFmpeg will be running 10x slower - but we're doing it for your safety. All your videos will appear green - safety first, working software later.

We’ve agreed to a partnership with @SpaceX that will substantially increase our compute capacity. This, along with our other recent compute deals, means that we’ve been able to increase our usage limits for Claude Code and the Claude API.

twitter hype is out of control again. we are not gonna deploy AGI next month, nor have we built it. we have some very cool stuff for you but pls chill and cut your expectations 100x!

🚨 GB News has won in the High Court against Ofcom—the first time Ofcom has lost a judicial review of a broadcasting code decision. This attempt to silence GB News shows free speech is under attack, but I thank the Court for defending The People’s Channel. Go GB News Go!

GPT-5.4 is launching, available now in the API and Codex and rolling out over the course of the day in ChatGPT. It's much better at knowledge work and web search, and it has native computer use capabilities. You can steer it mid-response, and it supports 1m tokens of context.

We’re bringing Codex and ChatGPT together in one desktop app. The same powerful coding agent, now alongside ChatGPT Work, with new coding workflows, a new Chrome extension, revamped in-app browser, and faster Computer Use powered by GPT-5.6. t.co

📣 What if every open issue had a Codex agent? That’s the idea behind Symphony, an open-source agent orchestrator for Codex that turns task trackers into always-on systems for agentic work, letting humans focus on review and direction.

OpenAI Developers

Codex now generates higher-quality spreadsheets, slide decks, and documents with GPT-5.5 in @Microsoft Office and @googledrive . A new file viewer in the app makes it faster to review, revise, and iterate, so files are ready to share sooner.

GPT-5.5 is here. It’s our smartest frontier model yet, introducing a new class of intelligence for agentic coding, computer use, knowledge work, and scientific research. Rolling out in ChatGPT and Codex today. API is coming soon.

Chronicle runs background agents to build memories from screen captures. It uses rate limits quickly. Screen captures are stored temporarily on device to generate memories—also stored on device. You can inspect and edit memories. Be aware that other apps may access these files.

OpenAI Developers

Last week, we released a preview of memories in Codex. Today, we’re expanding the experiment with Chronicle, which improves memories using recent screen context. Now, Codex can help with what you’ve been working on without you restating context.
