One developer ranked coworkers. Another turned Hogwarts into a gym.

Happy Friday!
Every new AI release comes with two things: a demo from the company and a much crazier demo from the internet.
A few days after Claude Fable launched, someone used it to figure out which coworker raises their blood pressure the most.
That's when you know a model has escaped the lab.
Here's What's Inside This Edition:
• Someone Used Claude's Fable to Rank Coworkers
• AI Turned Hogwarts Into a Gym
• OpenAI Is Giving Away Extra Codex Usage
• Claim Up to $5,000 in AWS Credits
• Theker Raises $85M for General-Purpose Robots
• Anthropic Changes Course on Fable Safety
• SpaceX Hits a Record Valuation
Most startups spend hundreds, or even thousands, of dollars each month on cloud infrastructure before generating meaningful revenue. What many founders don't realize is that AWS offers up to $5,000 in startup credits, yet thousands never claim them.
👉 $5,000 in AWS Credits – No VC backing or fundraising milestones required. Just the right application process and startup setup.
👉 50+ Additional Startup Perks – AWS is only the beginning. Founders can unlock offers from dozens of other platforms, such as OpenAI and HubSpot.
👉 Over $400,000 in Potential Savings – Combined startup programs can provide access to credits, software, and infrastructure worth hundreds of thousands of dollars.
We secured approval ourselves and turned the process into a step-by-step masterclass. Join 1,200+ founders who have used it to unlock AWS credits and access valuable startup perks.
Society’s response to artificial intelligence will be fascinating.

⚡ Meanwhile in AI
OpenAI introduced "rate limit banking" for Codex. Invite a friend, and when they send their first Codex message, both of you get an extra usage reset.
It's basically a referral program, except the currency is AI coding time.
Startup Theker just raised $85 million to build factory robots designed to handle a wide range of tasks instead of a single job.
The goal isn't a better robot. It's a robot that can do almost everything.
After facing criticism, Anthropic has updated its approach to safety around Claude Fable.
The debate over powerful AI models is no longer just about capability. It's about how much freedom is too much freedom.
SpaceX shares are reportedly being valued at $135 each in a new transaction, pushing the company's valuation even higher.
At this point, SpaceX is starting to look less like a startup and more like its own economy.
Ever wondered which coworker secretly raises your blood pressure?
One developer decided to find out. He used Claude Fable 5 to pull heart rate data from his WHOOP tracker, then matched stress spikes with meetings on his calendar.
What he got was a surprisingly detailed ranking of coworkers based on which meetings seemed to stress him out the most.
It's a funny experiment, but it also shows how easy it has become to build highly personalized tools with AI. A project like this would've been a headache not long ago. Now it's the kind of thing someone can put together over a weekend.

What if Hogwarts had a gym instead of a Quidditch pitch?
A viral AI video imagines Harry Potter as a full-blown fitness influencer, complete with giant biceps, gym selfies, and a Hogwarts packed with people who clearly never skip leg day.
It's completely ridiculous. And somehow, that's what makes it so entertaining. The video feels like one of those internet jokes that should never work, but you end up watching the whole thing anyway.
