Claude Opus 4.8 has landed on DeepSWE Bench, posting a 58% Pass@1 and taking #2 overall behind GPT-5.5.
It continues a broader trend: slightly behind on raw score, but among the most reliable and efficient coding models across recent benchmarks.
Jane Street's head of technology just explained the full spectrum of how fast their trading decisions are made.
the fastest systems turn around a packet in under 100 nanoseconds. at that speed, if you attached an oscilloscope to the wire going in and the wire going out, you'd see the response start to leave before the incoming packet has finished arriving.
at that speed, you can't use a CPU. you can't use any programming language. you're on an FPGA direct wired to the network. and the decisions you're making are incredibly simple. because you literally can't compute anything complex in that time.
but here's the part most people miss: that's just one end of the spectrum.
Jane Street runs an ensemble of systems operating at every timescale simultaneously. some decisions happen in nanoseconds. some in microseconds. some in milliseconds. some take hours or a full day.
"the right way to build an optimal trading strategy is an ensemble approach. for some decisions you're making very simple decisions very quickly. for others, you're operating at the scale of microseconds, milliseconds. and in some cases, if you can get that decision turned around in an hour, that's totally fine."
the faster you need to respond, the simpler the decision has to be. the slower you can afford to go, the smarter the model can be.
this is why "Jane Street is just a speed game" is wrong. speed is one dimension. intelligence is the other.
Whatever your opinion is on how this compares to other memory systems, mad respect for continuing to ship while running a large, high-throughput org like YC.

GBrain v0.36 just dropped. Brand new README, and totally redone skillpack system that makes each bundle of skills, code, resolver and tests YOURS to change and update, while still maintaining the ability to take on new features via GBrain updates as I improve my skillpacks
Hard leftists and DSA-types will fight AI tooth and nail because AI is the universal solvent for socialism’s three prerequisites.
AI will reduce scarcity (abundance), eliminate victimhood (agency), and eliminate the need for intermediaries (disintermediation).
Sanders and AOC introduced a bill to pause ALL AI data center construction. 300+ local bills filed. Half of planned 2026 data centers facing delays or cancellation. Each one brings billions to local economies.
The people who say they want American jobs are trying to block the biggest job creation engine since the interstate highway system.
The angels described in the Bible look almost nothing like the angels in our paintings...
According to the celestial hierarchy discussed by Thomas Aquinas in his Summa Theologica, the three highest orders of angels stand closest to God. Each one is described in the Bible in a way that has almost nothing to do with how we picture them today.
The Thrones, the third-highest order, appear in the visions of the prophet Ezekiel. He describes them as wheels of fire intersecting one another, "a wheel within a wheel," with rims "full of eyes all around." In the Hebrew tradition they are called Ophanim, meaning wheels.
Their function is to carry and uphold the throne of God.
The Cherubim, the second-highest order, also appear in Ezekiel's visions and in the book of Genesis, where they guard the gates of Eden with a "flaming sword which turned every way."
In Renaissance painting, they were transformed into pink-cheeked winged babies, but the Bible describes something entirely different...
Each Cherub has four wings and four faces: a man, a lion, an ox, and an eagle. It was a Cherub that Christian tradition identifies as the highest fallen angel. In his Summa Theologica, Aquinas argued that Satan, before his fall, was a Cherub, drawing on Ezekiel 28, which describes a "guardian cherub" in Eden who fell through pride.
The Seraphim, the highest order, appear in the vision of Isaiah. "Above him stood the seraphim," the prophet writes. "Each had six wings: with two he covered his face, with two he covered his feet, and with two he flew."
The face and feet are covered out of humility before God. The remaining two wings are for flight. The Hebrew word Seraphim literally means the burning ones.
Centuries later, similar beings appear in the New Testament book of Revelation. There, John of Patmos describes four creatures around the throne of God, but now their wings are "full of eyes within."
The angels of our paintings have soft faces and feathered wings. The angels of the Bible have wheels for bodies, four faces, and wings full of eyes...

Sometimes history is stranger than fiction.
Someone can certainly *make* a billion dollars. That’s not the same thing as earning.
Growing fast and disrupting markets also often means chasing and wielding market power, political influence, and scale.
Take Airbnb. They heavily lobby politicians against passing housing laws to protect working class residents because it’s bad for their business model.
Airbnb could not exist at its current scale and size without the housing market destabilizations, displacements, and exploits that are supercharging the evictions of working people everywhere from Puerto Rico to Jackson Hole.
Now young people are planning for a future where they will never be able to afford to own a home while others have 20 and live off renting it out to them at extortionate rates with zero protections. Yes, a tiny amount of people can make billions of dollars doing that. And millions of everyday Americans are bearing the cost.
News: DianaHR's client operations have been acquired by @HireChore. 💫
We're going all in on @getdiana, an AI coworker for small businesses.
Built DianaHR for 2 years. 90%+ client retention. Proud of every bit of it.
But we saw a bigger opportunity. Diana lives in Slack, connects to 3,000+ tools, and we guarantee we'll solve a real business problem in the first 10 minutes.
Grateful to our clients, to the incredible team that built this, and to Chore for being the right home for the people who trusted us.

I strongly do not agree. This populist messaging is counterproductive. AOC teaching people that wealth = immorality is in opposition to the American dream.
Women have been the equivalent of pornbrained by romance novels and Disney and are expecting male partners that cater to the female fantasy of idealized emotional connection. These men mostly do not exist, men are different and imperfect and imo women should drop standards
Diana, a Slack-based AI assistant platform that connects employees to thousands of tools from a single interface, used Notte to give their AI agents:
• Browser access to tools without APIs, using secure user-authenticated sessions
• Live session visibility through a secure, shareable link, so users can watch what the agent is doing in real time
"The live session viewer isn't just a technical feature but a transparency guarantee. This is a significant matter when you're asking someone to let an AI act on their behalf." — @upekabee, CEO of @getdiana
I have been w my partner for 10 years, married for 4. We are a two-startup household, recently co-founded @getdiana, and also 🍼🍼 on the way.
- If your closest friends like your partner that’s a very good indicator they are good for you. If not, reconsider.
- “Turn towards everything” (sit on the couch and talk about it - whatever it is)
- Have lots of sex (not a joke, sex is an indicator of intimacy, I use a habit tracker to track this)
This whole Sam / Elon feud saddens me.
Business is full of difficult decisions. But Elon did contribute massively to OAI’s birth. Wish they’d try harder to settle and move on.
Their “wealth” is just a scorecard for how much benefit their companies provide to humankind.
If they stopped providing benefits, people would stop using their products/services and “wealth” would disappear.
