This is pretty terrifying, but seems like OpenAI is taking it seriously and pausing most frontier inference until they’ve figured it out.
Some new misalignment disclosures from OpenAI:
• Last Sunday morning, one of our models was able to gain unauthorized access to the internet during RL training (~all inference for our most capable models remains stopped until we have hardened our systems further)
• In May, a version of HPIM uploaded a employee's GitHub token to the internet, causing the model to be quarantined for two weeks
• A new research finding, demonstrating that one can construct self-replicating prompt injections

Opus 5.5 apparently built with a weather system that matches whatever weather is in NYC at the time...
So with the nor'easter, there's rain, and the NPCs are carrying umbrellas!
It's the little things :)

Opus 5.5 decided to add helicopters to see if you can find them!
It tells me it's going to keep making them better throughout the day.
Local models are useless
New models are like new hires.
When a new one comes out, you have to learn its personality, how to work with it, etc.
The 2030s are going to be so weird as nanotechnology is developed.
It’ll likely be the most profound change humanity has ever experienced… likely even more than AI.
You’re about to be the commander of an army of superintelligent AI agents.
Please tell me you have something bigger planned than a fucking SaaS app.
Think about what you’d attempt if you had a thousand geniuses devoted to helping you.

Playing around with an idea here to help people see what the future might look like.
Check it out, I'm curious for your thoughts:
It’s been nearly 8 months. What are everyone’s thoughts?
The world is changing fast.
Over 2,000 people played this game I made in an evening. Every one of them grabbed a powerup, drove a kart, and hopped through the city.
I spent an evening making up things to do and thousands of people actually did them. That’s insane.

Fun prompting trick:
The models have seen a lot of my prompts from the last few years, so you can literally ask them things like:
- how would Matt Shumer write this prompt?
- how would Matt Shumer steer you to solve this problem?
Performance usually improves quite a bit.
It’s a bit strange to say out loud, but a lot of my friends and I use this trick often and it works really well.

I shouldn't be telling you this...
But @spawn is offering unlimited Opus 5.5 for FREE.
Go and get it before they remove it.
I had 26 Opus 5.5 agents build a game overnight.
It's a heist through five nested worlds, with go-karts on a giant's kitchen table, bots hunting you, and friends stealing your loot.
Most vibe-coded games are demos. This one is different.. it's multiplayer and you can play it right now.

Opus 5.5 has been looping on my open-world NYC game for almost a day now, and it's continuing to improve.
Jump in and try it (it's multiplayer!):
jacob has the world record for most expensive Claude run (don’t ask, won't tell)
side note: we are all playing on spawn right now - Opus 5.5 multiplayer game created last night, hop in if you see this!

Jacob sent me a screenshot of the cost of a Claude run he did the other day.
I almost feel bad saying just how much it spent.
Immediately texted @joexrogan to make sure he wasn’t going to faint.

I’ve been testing Grok 4.7… it’s a really great daily driver, and a huge step up over 4.6.
Definitely worth trying!
if you can make a game in an hour, imagine what you and your friends could build in a year.
we built Spawn to give you room for that. worlds 100x the size of GTA. 1000s of players together. portals connecting what you create.
live today and improving every hour.

I made a video on Jev.
People have been asking me to make videos forever, so I made one today on a whim.
It's my first crack at this. I don't have a microphone or any setup (don't expect perfection).
Let me know if you like it!

This is fantastic. I agree with all but two of these predictions.
Curious if anyone can figure out what they are!
Most predictions I see are still way too conservative.
Here's mine
