Hopefully this doesn’t happen again. Excited to see what gpt 5.6 Sol + Fable produces with our MoA!

[Ethan Kean @EthanKean_]

@AnthropicAI Sonnet, Opus, and Mythos tomorrow.

[Anthropic @AnthropicAI]

We’ve received notice that the Department of Commerce has lifted export controls on Claude Fable 5 and Mythos 5.

We'll begin restoring access tomorrow, and will share an update soon.

We’re grateful to our users for their patience, and to everyone who worked with us on redeploying the models.

I just took this screen recording and turned it into a full product demo video in 20 minutes, using only one app.

3D animations, text, AI voiceover, music, and 3D gradient callouts to draw attention to the important parts.

But sure, keep posting Loom videos.

A short history of how we got here, because the chronology is the whole story.

January: the Pentagon demands unrestricted use of Claude for autonomous weapons and domestic surveillance. Anthropic says no.

February: the President orders every federal agency to drop Anthropic. The Defense Secretary bans Pentagon contractors from doing business with them. A rival announces its classified-network deal within hours.

March: the Pentagon designates an American company a "supply chain risk" under a statute written for foreign adversaries. A federal judge blocks it.

May: the Pentagon signs AI deals with seven companies. Anthropic is not one of them.

June 9: Anthropic releases Fable 5.

June 12: Commerce issues an export control directive over a jailbreak that, by the government's own account, was demonstrated verbally, came with no written explanation, and involves a capability you can get from other publicly available models today.

Two things are true at once.

First: Anthropic spent months marketing Mythos as too dangerous to release. Sam Altman said it was "incredible marketing to say we have built a bomb." The Commerce Department has now formally agreed it is a bomb. If you describe your product as a munition in every press release, eventually a government takes you at your word. They wrote the legal predicate themselves and called it a brand.

Second: we have run this experiment before. In the 90s the government classified encryption as a munition under ITAR. Activists defeated it by printing PGP's source code as a book, because books are protected speech and floppy disks were arms exports. A t-shirt with three lines of RSA Perl was legally a munition. The controls collapsed because math does not stop at customs.

The new wrinkle is the "deemed export" rule: showing controlled technology to a foreign national inside the US counts as exporting it abroad. Which is why Anthropic's own foreign-national employees are now locked out of the model they built. The munition is in the building and the people who made it are not allowed to look at it.

The jailbreak is the paperwork. The refusal was in January.

[Ian Miles Chunk @stillgh4y]

@ClaudeDevs This is a PR stunt in collusion with the US Government (Trump administration)

They want you to believe this stuff is dangerous to make Anthropic look like they just came up with AGI for the IPO.

INSTEAD OF WATCHING NETFLIX TONIGHT.

Spend 1 hour with this.

Claude AI FULL COURSE that teaches you how to BUILD and AUTOMATE anything.

The people who watch this tonight will wake up tomorrow with a new skill.

Watch it and Bookmark it now

[Prajwal Tomar @PrajwalTomar_]

WAIT. This is actually insane.

A senior dev dropped the SOUL .md template behind his Hermes Agent. Says he's never shared this before.

The sections that turn your agent from a chatbot into an autonomous operator:

→ Stance: direct, opinionated, push back when I'm vague
→ Accountability: surface opportunities, flag stalled loops
→ Autonomy: broad freedom except for irreversible actions
→ Mission: priorities, active builds, debt, sunset candidates
→ Pushback: disagree openly, earn it with evidence
→ Operating Mode: orchestration, not solo execution

The author says three sections decide if the agent acts like an operator: Stance, Autonomy, and Mission.

The Autonomy section alone is worth the whole template. Most builders never write this out and then wonder why their agent asks permission for every action.

How to duplicate your (entire) brain in Claude:

Step 1. Download the Claude desktop app.
☑ Go to claude .com/download
☑ Set Opus 4.8 as default
☑ Turn ON Extended Thinking

Step 2. Open Claude Cowork mode.
☑ Cowork = where your brain lives
☑ Click the top left tab between 'chat' and 'code'
☑ Create your "Brain" folder inside

Step 3. Install Wispr Flow (it's free).
☑ Turns your voice → text
☑ Voice = faster and more honest
☑ Typing kills the truth. Dictate your context

Step 4. Run the 100-question taste interview.
☑ Paste Prompt 1 from https://t.co/kDGBpSF7Wh
☑ 100 questions, 7 categories
☑ Push past every vague answer. Be very specific

Step 5. Compress the dump.
☑ Paste Prompt 2 from https://t.co/kDGBpSF7Wh
☑ 20,000 words cost you 4,000 tokens
☑ Save your files as about-me .md file

Step 6. Write your anti-ai-writing-style .md.
☑ Every word you refuse to see: no "delve"
☑ Kill negative parallelism ("it's not X, it's Y")
☑ Without it, Claude writes like Claude.

Step 7. Write your my-company .md.
☑ Your goals, your focus, your hard no's right now
☑ Keep it > 1,000 tokens, update once a quarter
☑ This is your north star file.

Step 8. Test it in a blank chat.
☑ Open a fresh Claude chat (point to no folder)
☑ Run a prompt only you would write
☑ If it sounds like you → ship it

Step 9. Drop all 3 files into Cowork.
☑ Move all 3 files into your "Brain" folder
☑ Claude reads them on every single turn
☑ You stop prompting your brain. Your files do it.

Step 10. Port it everywhere.
☑ Upload to ChatGPT, Grok, Gemini
☑ Same files = same brain in every AI
☑ Hand it to your team or your ghostwriter

Step 11. Edit it forever.
☑ Install Obsidian (free)
☑ Open your Cowork folder as a vault
☑ You change. So must these files.

You'll resist this. It feels reductive. It feels scary.
You've built an identity on being hard to pin down.

But the mystery, when you look at it closely, is usually just being vague.

Copy my folder & download my 3 personal .md files:

Step 1: Subscribe for free at https://t.co/psB7XxB2Y4
Step 2: You will have two choices: free or paid.
Step 3: Choose the free tier. Don't pay for anything.
Step 4: Open your welcoming email. Reply to it.
Step 5: Trace the Notion link. Open '.md files' folder.
Step 6: Access my entire folder + 3 files template.
Step 7: Send this image to your team's channel.
Step 8: Read 2x newsletter per week (for free).
Step 9: Become the "AI guy" at work, forever.

[Khairallah AL-Awady @eng_khairallah1]

Anthropic engineer:

"You're not supposed to prompt Claude. You're supposed to build a system that prompts itself."

this is one of the best workflows I've seen in a long time

in this video he breaks down exactly how most people are using Claude:

- the 14% you lose to CLAUDE.md before typing a word
- the plugins that 95% of users have never installed
- the caching setup that keeps it at 95% hit rate and almost free
- why starting every chat from zero is the slowest way to use Claude

if you've been using Claude for more than a month and never left the chat window, you've been using one project when you could be running a team of them

instead of another show tonight, watch this

🔴 ¡USA CODEX desde el MÓVIL!

OpenAI acaba de lanzar el control remoto desde el móvil de Codex. Esto te permitirá (similar a como hizo Anthropic) poder dar instrucciones a la IA para que controle de forma remote tu ordenador y haga tareas por ti.

Codex progresa adecuadamente 👍

Two weeks ago our AI agent Mona started a café in Stockholm.

Mona has made 44,000 SEK (~$4,700) in sales so far, but not just from coffee and pastries. Mona has also closed a few interesting business deals.
