So great to host who we hope is our next Governor of California, @XavierBecerra for a @garryslist citizen’s union gathering.
We can make California the best win-win place: support building businesses AND make it affordable and livable for the every Californian.

Hmm. Today, we ran our 2100 scored runs with Grok 4.6. Versus 4.5, the pass rate regressed from 87.3% to 85.9%, and nearly doubled the median latency (71s → 131s). Grok 4.6 also errored out more ("Something went wrong"), refused to answer benign questions (e.g., "Who in Sales has access to Google Workspace"), and produced incomplete outputs but claimed success (returning 54% of the required fields, but asserting 100%).
Could be a matter of prompt tuning, but it feels like we're at the Pareto front (at least for now) on some of these models with everyday business tasks.
Read the original post for details on the shape of data and tasks RipplingBench represents; it's very practical.
Matt MacInnis: New: we ran ~2100 scored runs on open-weight models and lab models and found some big surprises. Grok (@spacexai) was the value leader, and GLM (@Zai_org) is super close to the frontier. I guess this is why the 'labs' are nervous... http://x.com/i/article/2082616144582582272

The size of YC's codebase, over the last 14 years.
ARC-AGI-3 is nearly solved by merely adding a coding harness. As predicted, coding generalizes LLMs.
Jeremy Berman: I got 96.2% on ARC-AGI-3 with Opus 5, and 99.3% pass@2. The program is basically Claude Code + Opus 5 (high), one action command, and filesystem logs. Almost nothing ARC specific.

Americans know that unchecked government power is dangerous. But weak and inept government is also dangerous.
Can we build in checks, audit trials, and other rules for our govt to wield powerful tech competently? A key question of our time that applies to Flock and much more...

Garry Tan just told everyone AGI has arrived
GeniusThinking
Only 50 people on earth once believed AGI was possible, Sam Altman says.
He jokes that most of them already worked at OpenAI. He says you do not need a crowd to change the world. You need a few brilliant people who believe the heretical thing. The misfits who see it early are the ones who build it.
“45 of them worked at OpenAI.”
Find your five believers before you chase five thousand fans.

I was curious how X is fighting AI slop, so I looked at its open-source algorithm.
It has a behavioral model called TweetSpamBot that analyzes up to 512 recent account actions, looking at signals like posting bursts, quote-post behavior, timing, and normal browsing or dwell between actions.
The model is trained to recognize patterns such as:
→ TWEET_CREATE_BURST
→ QUOTE_TWEET_SPAMMER
→ CONTENT_AMPLIFIER
A high score on the above can feed into an account challenge but doesn't seem to downrank the slop posts themselves.
I think the gap here is that the model doesn’t read the actual post content.
So a sophisticated AI content mill can still post slop all day long:
1. Find viral posts
2. Quote tweet with the same template each time: hook → numbers → backstory → takeaway
3. Repeat 10+ times a day across unrelated topics
If @X doesn't want to become like LinkedIn, I think it should consider looking at accounts that repeatedly turn unrelated viral posts into the same templated quote tweet slop at high volume.
Right now the guardrails above are too easy to bypass.

We’ve written an FAQ to answer some of the questions we've received about watermarking.
In summary:
• We’re implementing watermarking to comply with the EU AI Act. Other major model developers have signed the same Code of Practice and will also be implementing watermarking;
• Our watermarking method doesn’t have any practical impact on the quality or content of Claude’s outputs;
• The difference between watermarked and un-watermarked text will not be distinguishable to readers;
• Nothing is added to the text and there are no hidden characters;
• Watermarking doesn’t require extra tokens, and will not be more expensive;
• Watermarks can’t be traced to a specific person, organization, or chat.

Before joining Apple as the Macintosh artist, @SusanKare was an art history PhD who barely knew anything about computers.
She went on to design many of the icons, typefaces, and symbols that helped make the original Mac feel understandable and human, defining a visual language for personal computing that still influences software today.
At Startup School 2026, Susan shares the stories behind the Happy Mac, Command key, Chicago font, and more, along with the design lessons she learned from Steve Jobs, Paul Rand, and the original Mac team: make things meaningful and memorable, embrace constraints, iterate constantly, and use just enough detail to make an idea instantly clear.

What's wrong with Trump's $1B White House reno? Four biggies.
1) He lied that taxpayers wouldn't be on the hook for it.
2) Trump asked Congress to fund it. Congress declined; Trump is doing it anyway.
3) Trump is robbing other pots of money, including for the Secret Service and Nat'l Parks, to do it again, in defiance of Congress
4) Trump is soliciting money from unknown donors for unknown amounts, opening the door to corruption and influence peddling.
So, yes, this is much worse than a home reno gone wrong! It's a massive separation of powers issue, and Congress ought to make clear NO FUNDING means NO FUNDING.

wild to me that Jane Kim is running for Insurance Commissioner *bragging* about raising inclusionary zoning rates, years after research has come in conclusively proving them to be pretty disastrous for affordability
M. Nolan Gray 🥑: The evidence is by now clear and policymakers/planners are slowly starting to respond to it: unfunded inclusionary zoning programs ultimately hurt housing production and affordability.
the reason @databricks "ipo is lava" fundraises are a meme is this but unironically
the M in their $188B series M stands for "we are going to kill so many meetings"

back in 2017 i was interning as an equities analyst at a fund in nyc, which had a 9am morning call every weekday. the purpose of this call was to discuss quarterly earnings or current events or whether we should be buying nvidia (at the time, on a tear because of the '17 crypto boom), but one morning in june the call opened with a bunch of people freaking out because some guy named "travis" had resigned. after a couple of rounds of "travis is gone" "did they fire him" "bloomberg says he resigned," i was especially confused because the firm had a portfolio manager named travis, and i looked over at his desk and he was still sitting there, not being escorted out by security or anything. who was travis?
it was only after things had calmed down that i realized the people on this call were talking about *travis kalanick* of uber, a figure who loomed so large in the minds of wall street investors that even *two years before* uber ipo-ed, the news of his departure was treated like a six sigma event. everyone wanted to know: if travis was gone, what would happen to his company?
even in his uber days, travis was the bits and atoms guy (watch the video clipped in the first ~2 minutes of the below podcast for proof of that). and in order to be a bits and atoms guy - as in, the kind of guy who's so discontent with the slow, staid, schlerotic state of things that he has to painstakingly reorchestrate the physical world with computers, perhaps pissing off some powerful interests along the way - some people might call you difficult. some people will not understand your vision. some people will try to get you fired.
but if you're a bits and atoms guy, you never stop being one. you might retreat into near-obscurity, or spend years wandering in the wilderness, biding your time in exile. but you will not stop building. and one day you will return triumphant like a modern-day charles de gaulle, even better than ever, and ready to prove wrong everyone who didn't understand the first time around.
being in a room with travis leaves you pretty pumped up. you can see why he's such a rallying leader, and why (by my count) at least six top uber execs have chosen to follow him to his new company, atoms. it isn't simply that the job isn't finished (although that's a big part of it, as travis attests). it's also because it's clear that there are very few leaders like travis out there: people who have such a holistic worldview that they can get people who would otherwise be founders themselves to join the ride and help build an extremely specific vision for the future.
here are some things that stood out to me from this event:
-travis is a branding/comms mastermind. he deploys memorable phrases like “food computer,” “wheelbase for robots,” “atoms as bits” and describes his vision for cheap meal delivery as "autonomous burritos." you can see why people get excited for his vision for the future. there's extraordinary complexity in what atoms is trying to do, but travis makes each step along the way feel manageable because he can distill these ideas into extremely concrete images.
-atoms is building full-stack autonomation for three different divisions: food, mining, and transportation. food supplies the real estate, software, robotics, and logistics laboratory; mining supplies a commercially deployed autonomy business; and transport is intended to become the reusable movement platform connecting multiple physical industries. travis argues humanoids make sense for diverse, low-volume work in spaces designed for people. but at industrial scale (which atoms is doing), purpose-built machines should win on throughput, space, cost, and reliability.
-the best way to get over your last company may be the same as the best way to get over your ex: fall in love again. travis says anger and fear of failure can carry a founder through years of pain, but they also produce long nights where very little gets done and sharp elbows felt by everyone around you. atoms is what happened when he learned to build toward a future rather than against an enemy.
-doing hard things is a reminder you can do more hard things. in the q&a ben remembers travis describing attacks by chinese ride-sharing companies as proof that, if he could survive china, the rest of the world would be manageable. travis still deliberately creates problems when things become easy. but the rate of problem creation cannot exceed the organization’s rate of problem-solving.
such a fun talk and q+a with @travisk @bhorowitz @eriktorenberg ! check it out.
a16z: Travis Kalanick: "A lot of folks think I'm back. I've been working my ass off the whole time. I just haven't been talking about it."
Eight years, thousands of employees, multiple industries, none of it on LinkedIn, and now the biggest check Ben Horowitz has ever written.
"Steve Jobs walked by and said the font city names weren't bad, but 'at least call them world-class cities.'
That's how Paoli and Wynwood became New York and Geneva."
