Google just cracked recursive self-improvement.

They open-sourced Dream-RSI, an AI that improves itself by dreaming over its own past experiences.

Until now, self-improving AI faced a massive wall.

To get smarter, an AI agent has to explore and discover new solutions.

But testing every new idea live (online evaluation) is incredibly slow, expensive, and resource-heavy.

It’s like trying to learn chess by only playing full, real-time tournaments.

Dream-RSI completely changes the paradigm.

Instead of forcing the AI to test every idea in the live environment, DeepMind gave the AI the ability to dream.

Here is exactly how it works:

Every time the agent discovers something new, it logs the history.

Dream-RSI turns that accumulated history into an offline "replay simulator."

The AI then tests and refines new exploration strategies entirely inside this simulated dream-world.

The result? Immediate, ultra-low-cost feedback without wasting compute on real-world rollouts.

The self-improving loop is now closed, and massively scalable:

• The AI dreams up better strategies offline in the simulator.
• It deploys those upgraded strategies online to make real discoveries.
• Those new discoveries expand the simulator's database.
• The AI dreams again, only this time, it is vastly smarter.

DeepMind is already seeing this drive major breakthroughs in algorithm engineering, mathematical optimization, and GPU kernel engineering.

The takeaway is monumental.

We are moving past AIs that just answer questions or write code.

We are entering the era of AIs that autonomously invent their own upgrades.

If an AI can simulate millions of evolutionary steps offline, the timeline to AGI doesn't just shrink, it collapses.

To recursively self-improve, AI needed to learn how to dream.

Now, history is the world it dreams in

Steep rise in the number of people at OpenAI and Anthropic having existential crises these past few weeks.

From conversations with people at and around both labs, it's increasingly clear to me that AGI has essentially arrived, just not publicly. We're likely months, not years, from these models being widely available. And that puts us at a fork in the road, with the point of no return not far past it.

The scramble to act we've seen in the last or week or so is warranted imo. But all of this is super hard to navigate, and the obvious dilemma is that if the U.S. slows its frontier work, it cedes ground to China. Unless Beijing agrees to do the same... which I doubt happens anytime soon.

Time is short - and the decisions made over the next twelve months will be studied for decades to come.

To commemorate the 25th anniversary of 9/11, CIA released 71 President's Daily Briefs to give Americans a glimpse into our most sensitive intelligence from the years before and day after one of our Nation's darkest moments.

Instead of watching an hour of Netflix, watch this 2 hour hour Stanford lecture will teach you more about how LLMs like ChatGPT and Claude are built than most people working at top AI companies learn in their entire careers.

The killing of Alex Pretti is a heartbreaking tragedy. It should also be a wake-up call to every American, regardless of party, that many of our core values as a nation are increasingly under assault.

BREAKING: Trump just ordered "A TOTAL AND COMPLETE BLOCKADE OF ALL SANCTIONED OIL TANKERS going into, and out of, Venezuela."

This is an ACT of WAR according to international Law:

Declaring a blockade without Congress would be an illegal initiation of hostilities.

A president cannot legally start a blockade of another country on their own without:

- A formal Authorization for Use of Military Force (AUMF), or

- A declaration of war

Neither exists for Venezuela. Venezuela’s oil is Venezuela’s sovereign resource, not U.S. property.

Wreckage from PSA Airlines Flight 5342, the Canadair Regional Jet CRJ-700 which crashed earlier tonight in the Potomac River while landing at Ronald Reagan Washington National Airport in D.C. @andyharnik

[Kyle Salewski @Sa_Les_Ski]

I took this video 6 days ago leaving Reagan International Airport and thought it was kind of crazy seeing these choppers right next to us. I wonder if it was something like this that caused the collision tonight.

"Failure" in America's proof you took a big swing and missed … this time.

In the UK, it’s like a generational stain we try scrubbing off quietly behind closed doors.

No wonder America scales while Britain stagnates
