Very cool - but key thought exercise: How much of this event do you think was designed to help justify a @SpaceX @Tesla merger? Gives @solarcity @tesla vibes. But not saying that a merger wouldn’t make at least some sense. Optimus demos of robots servicing galactic data centers next? #teslaroadster #spacex #tesla #spacextesla

Reinforcement learning rewards convergence, and convergence is the opposite of discovery. We built the world’s first judgment model from the decisions papers erase: what to pursue, challenge, abandon, and revisit. Columbus-1 autonomously found a zero-click Bluetooth RCE and designed a 10-foot, self-landing rocket.

Superintelligence will be built on Self Improvement. Today @hexoai, we’re excited to release ‘SIA’ - an open-source Self-Improving AI, to achieve any goal through recursive self improvement. While trying to solve a problem, SIA doesn't just improve it's abilities by updating it's harness, it updates it's own weights as well.

Anthropic would have built this in a day and a dev would have tweeted the news. At OpenAI, an exec is telling you about a plan. That gap tells you everything. In the last 7 days, Anthropic shipped Dispatch, channels, voice mode, /loop, 1M context GA, MCP elicitation, persistent Cowork on mobile, Excel and PowerPoint cross-app context, inline charts, and 64k default output tokens. Felix Rieseberg tweeted "we're shipping Dispatch" and you could control your desktop Claude from your phone that afternoon. Every launch came from an engineering account or a GitHub release. In the same 7 days, OpenAI shipped GPT-5.4 mini and nano. Redesigned the model picker. Sunset the "Nerdy" personality preset. Announced three acquisitions. To find a comparable volume of shipped product from OpenAI, you have to rewind to December. This is the most underrated difference in AI right now. Anthropic PMs don't write PRDs. Boris Cherny, head of Claude Code, ships 10 to 30 PRs a day and hasn't written code by hand since November. 60 to 100 internal releases daily. Cowork was built with Claude Code in 10 days. The tools build the next version of the tools. Every cycle compresses the last one. Engineers are empowered to ship and announce. The entire org runs like a product team, not a corporation. OpenAI has the opposite problem. Fidji Simo is CEO of Applications, a title that exists because engineers aren't empowered to ship without executive approval chains. She joined from Instacart. Before that, a decade at Meta running the Facebook app. Since she arrived, OpenAI has acquired 12 companies for $11 billion in 10 months and announced a "superapp" consolidation through the Wall Street Journal. The exec responsible for shipping it is tweeting about "phases of exploration and refocus" on the product she hasn't shipped yet. That's what happens when you layer a Meta-style product org on top of an AI lab. Decisions go up. Shipping slows down. Announcements replace releases. Anthropic's product announcements come from the people who wrote the code. OpenAI's come from the C-suite and the press. One of those loops compounds. The other one meetings.
Companies go through phases of exploration and phases of refocus; both are critical. But when new bets start to work, like we're seeing now with Codex, it's very important to double down on them and avoid distractions. Really glad we're seizing this moment.

By now, many of you have heard the news that Nvidia and Groq are forging a $20 bn partnership. Lots of people have been asking me about it so I wanted to share some thoughts. TLDR: Groq is the largest investment we made in @VitalStage Fund I, and we are very excited for them to partner deeply with Nvidia. In fact, in our original investment memo, we predicted that one of the large chip design firms like Nvidia would seek to acquire Groq within 2-3 years. Why? I explain more here: medium.com/@brianshin/why-i-…

AI is growing fast and there’s one project that really caught my attention. @joinableai is building something different: a decentralized AI workforce where humans stay in control, not corporations. Here’s the thing 85% of AI projects fail because they lack real human feedback. Joinable changes that by letting anyone become a verified AI contributor, helping train models faster while earning rewards along the way. They just launched the AI Vote Campaign: Model Clash, and it’s genuinely a fun, meaningful way to shape how AI learns. You simply compare two AI answers, vote for the better one, and leave quick feedback. Why join?
