OpenAI's Secret AI Just Solved 10 Math Problems That Stumped Geniuses For Decades — And It Only Cost $2,000

-

I've been following AI for years, and I thought I was past being truly shocked. Then OpenAI dropped this news and my jaw hit the floor.

OpenAI's next-generation AI model — an internal version called Astra — just solved ten open problems in mathematics and theoretical computer science that had stumped some of the brightest human minds on the planet. Not simple textbook problems. Not homework questions. We're talking about frontier research challenges that Fields Medal-winning mathematicians had been working on for decades.

And the total compute cost? About $2,000.

What Astra Actually Solved

The problems span eight completely different mathematical fields: high-dimensional geometry, coding theory, arithmetic circuit complexity, group theory, operator algebras, quantum complexity, lattice cryptography, and extremal combinatorics. These aren't niche areas — they're pillars of modern mathematics and computer science.

One of the highlights: Astra provided a construction proving the existence of non-sofic groups — a central open question in group theory that researchers had been chasing for over two decades. It also established new sphere-packing bounds and refuted a rigidity conjecture by Fields Medalist Alain Connes.

OpenAI published the formal Lean proofs on GitHub so the mathematical community could verify everything independently. This wasn't just a claim — it was receipts.

The Expert Reaction Says Everything

Here's the line that stopped me cold: Fields Medal winner Timothy Gowers — one of the most respected mathematicians alive — said he would recommend one of Astra's proofs for publication in a top journal without hesitation.

Read that again. A human Fields Medal winner said an AI's math proof is journal-worthy.

This isn't GPT-4 writing a mediocre essay. This is frontier research. The kind of work that, if a PhD student submitted it, would make their career.

Why OpenAI Chose Math to Debut Astra

Interesting strategic choice here. OpenAI could have debuted Astra with benchmark scores and marketing slides. Instead, they chose to show it doing verifiable, real mathematical discovery.

Why? Because math is the one domain where you can't fake it. Either the proof is valid or it isn't. There's no "close enough." The Lean proof system verifies every step computationally — so when Astra's proofs check out, there's no debate.

OpenAI is positioning Astra not as a chatbot, but as a genuine research tool. That's a very different pitch than we've seen before.

What This Means for Science and Research

If an AI can solve open mathematical problems for $2,000, what happens to the research pipeline? A few immediate implications:

  • Problems that might have taken a career to solve could be cracked in hours.
  • Fields that have been stuck for decades might suddenly unstick.
  • The bottleneck for mathematical progress might shift from human insight to compute budget.

This doesn't make mathematicians obsolete — you still need humans to ask the right questions, frame the problems, and interpret what the answers mean. But the actual proof-finding work? That just got turbocharged.

I've been watching AI make incremental progress on math benchmarks for two years. This is different. This is AI doing something genuinely new that matters to people who aren't in tech.

The Bigger Picture

We're in August 2026, and an AI just did real, original mathematical research at a cost most universities could afford on a grant. The question isn't whether AI will transform scientific research — it's already doing it.

The question is: how fast does this compound? If Astra can solve 10 problems now, what does the next version solve? What about the version after that?

I don't have answers. But I'm watching this space very closely — and if you're not, you should be.

This AI Startup Is Worth $26 Billion and Writes 90% of Its Own Code — Should Software Engineers Be Worried?

-
I've been watching the AI coding space very closely for the past year, and every few months something happens that forces me to recalibrate my sense of how fast things are moving. This week, that moment came from Cognition AI — the startup behind Devin, the AI software engineer — which just announced a $1 billion funding round at a $26 billion valuation . But the number that actually stopped me cold wasn't the valuation. It was this: 90% of Cognition's own code is now written by Devin. From $10B to $26B in Eight Months — The Numbers Are Staggering Let's put this in perspective. Just eight months ago, in September 2025, Cognition closed a $400 million round at a $10.2 billion valuation. Today, that valuation has more than doubled to $26 billion. The new round was co-led by Lux Capital, General Catalyst, and 8VC, with Ribbit Capital, Atreides Management, and Peter Thiel's Founders Fund also participating. But what's really driving this isn't hype — it...

Sony Smart Tags Review: The NFC Trick That Made My Life 10x More Convenient (Before Everyone Knew NFC Existed)

-
In 2012, NFC (Near Field Communication) was a technology that most smartphone owners had never used or even heard of. Sony released Smart Tags — small NFC stickers you could program to trigger actions on your Android phone with a single tap — and I became obsessed with them. Here's why they were brilliant, and why they pointed toward a future most people are only now catching up to. What Are Sony Smart Tags? Sony Smart Tags are small NFC-enabled stickers (about the size of a large coin) that you program using the NFC Smart Tags app on Android. Each tag can be loaded with a set of actions that trigger automatically when your phone touches it. One tap on the tag = multiple phone settings change instantly. Sony sold them in packs of 4, with different colors and designs. You stuck them places — your nightstand, your car dashboard, your desk, your bag — and each location became a context-aware shortcut. How I Actually Used Them Bedside tag (white): One tap when I got into bed tr...

WWDC 2026 Preview: Apple Needs to Fix Siri or It's Game Over for Apple Intelligence

-
Apple's WWDC 2026 kicks off on June 8, and the stakes couldn't be higher. While Google announced 900 million Gemini users at I/O last week, Apple is heading into its biggest developer conference with one uncomfortable question hanging over the whole event: what happened to Siri? I've been using Apple devices daily since the original iPhone, and I'll say it plainly — Apple Intelligence has been the most underwhelming software launch in Apple's recent history. WWDC 2026 is Apple's chance to fix that. Here's what they need to announce, what we're expecting, and what a failure would mean. The Problem Apple Needs to Solve When Apple announced Apple Intelligence at WWDC 2024, the demos were impressive. When the features started rolling out through 2025, the reality was a different story. The "new Siri" was slower, less reliable, and often less capable than the old one for basic tasks. The "Personal Context" features that were supposed ...
