We just launched Xirp, a vendor-neutral agentic development environment. One place to manage agent sessions across @ClaudeDevs, @GeminiApp CLI, and @OpenAI Codex. 1,300+ @Spotify engineers already use it. Now it's available for you to try. Learn more at https://t.co/Hwo8Qqx4OI.
Seeing people ask, “Does anyone even use Sonnet?” is genuinely making me mad lol. Like, what are you guys doing?
A repetitive task with a well-defined set of rules doesn’t need Fable. Sonnet can handle it just fine. You don’t need an expensive model for everything.
We're making Claude Sonnet 5's introductory pricing permanent.
We launched Sonnet 5 in June at $2 per million input tokens and $10 per million output tokens through August 31, and that price will remain unchanged.
New in Claude Code: your sessions can now message each other.
Instead of having to re-explain yourself in another session, you can now tell Claude to do it. It sends a summary (not your history or files), and the other session picks it up mid-task.
Ladies and gentlemen, it's time to pass the torch and demote myself to my natural state: a poster. I'll be stepping back from leading product for 𝕏 and will continue on as an advisor.
Serving the X community has been the privilege of a lifetime. X is, and will remain, the most important communication technology in history. But running this app is a 24/7 job and it's now time for me to take a breather.
The app is seeing unprecedented growth in new users & engagement. We continue to break records every month. We've climbed 70 spots in the App Store since this time last year.
And in the last 400 days, we rebuilt almost every aspect of X: the Timeline, the Android app, onboarding, notifications, chat and more.
We also launched nearly 30 new products while protecting the integrity of the town square: becoming the first app to show Country-of-Origin on profiles and mounting defenses against AI bots. There's certainly much more work to be done, but our foundation is stronger than ever.
None of this would have been possible without the incredible team here. The next leaders will take X to even greater heights with @benjitaylor on design, @singhai on core product engineering and @dinkin_flickaa on mobile engineering -- among many other great people.
Thank you to Elon and the X team for welcoming me into the company. See you on the Timeline.
Google just released free 2-hour course on full Graph engineering: 1 prompt → 100 agents → loops → graphs from 0% to 100%:
10% → 17:44 - build your first agent
30% → 39:30 - Loop engineering: iterate, check, break
60% → 1:12:38 - Graph engineering
75% → 1:34:26 - agents that throttle themselves
100% → 1:55:05 - full graph for multi-agentic systems
everyone builds one agent and calls it done - this is the full system where agents wire themselves into a graph
watch the course, build the graph - then read the full architecture below ↓
BREAKING: Trump Media has officially launched its new paid data service, providing faster access to Truth Social posts from President Trump.
The new service is called "Truth API" which gives firms "a direct, licensed, real-time feed of the platform’s most market-moving Truths," the company's CEO said in a press release.
The service reportedly costs as much as $100,000/month.
we built pdf-inspector so agents can process PDFs without waiting on OCR. it classifies any PDF in ~20ms and extracts clean markdown locally
→ 200 PDFs processed in 2.8s
→ top quality in extracting tables + graphs
→ built in rust
→ open source

OH. MY. GOODNESS.
CITADEL HAS BOUGHT A MAJORITY OF THE PUBLIC ASSETS FROM LEOPOLD'S SITUATIONAL AWARENESS FUND.
So...Citadel scares everyone on Tuesday about a surprise rate hike during FOMC that WE ALL KNEW was not going to happen...
On Wednesday, the entire market freaks out about the rate hike which causes the selling to compound on itself creating 50-70% drawdowns across the board in high beta semicondcutor names...
Which means Leopold who we now know had $45B of assets and was 400% LEVERED ends up being the sacrifice as he gets liquidated at what theoretically could be the bottom due to not having the margin requirements to keep solvent...
AND THE PERSON WHO CAUSED THE SELLOFF WITH THE RATE HIKE FEARS ENDS UP COMING IN TO BUY HIS ASSETS FOR 40 TO 50 CENTS ON THE DOLLAR.
By the way, Leopold is getting married this weekend. I think he wanted to make sure he wasn't getting margin called during his wedding.
A vet on wall street in Ken Griffin takes out the young new kid.
ABSOLUTE. CINEMA.
Leopold Aschenbrenner's Situational Awareness exited its entire public-equities book through a single-buyer transaction just as its former holdings are ripping today:
• $BE +26%
• $NBIS +25%
• $SHAZ +26%
• $IREN +25%
• $SNDK +20%
• $CRWV +20%
• $TE +14%
• $AMD +13%
Claude wiped an entire database. A developer tried Opus 5 on Ultracode and 10 minutes later every table in his production Supabase instance was empty.
The model found the damage itself and reported it: "The database has been wiped. This is my fault and I need to tell you immediately."
It doesn’t matter if open source software is developed by the CCP, the NSA, the Jews, ISIS, MAGA, ANTIFA, or the Illuminati.
It’s open source - just audit and run it yourself.
They can send me gold bricks too, as long as they’re at it.
For my first post, I’m sharing a letter @NVIDIA signed on why open models matter.
AI will transform every industry, power every company, and be built by every country.
Open models strengthen safety and cybersecurity, accelerate innovation and diffusion, and enable sovereignty.
The world needs both frontier closed models and frontier open models.
