PK9 and PK10 have fallen and the Paradigm Kryptos challenges are complete Congrats to @LazlosBatForm, @forwardsecrecy, and the rest of the PK Solvers Club As well as Opus 5.5, which made the final breakthrough Now on to K4!

Live discussion with @danrobinson and @MTSlive on pacing the frontier

After nearly six incredible years building spacecraft, I’m beginning a new chapter as an entrepreneur in residence (EIR) at @paradigm. Varda was a grand adventure and a one of one experience I’ll cherish forever. I had the rare privilege of joining the founding team and helping take a wild idea from zero to one, from a blank sheet of paper to hypersonic vehicles coming home from orbit. I’m incredibly proud of what we built together. Thank you to Will, Delian, and the whole team. Paradigm is giving me something incredibly cool. I’ll have the freedom to search for the next important thing worth building. This might look like a radical departure, but I see it as a chance to step back, look broadly, and follow my curiosity. An EIR sits somewhere between researcher, inventor, and founder in waiting. Paradigm feels like a natural home for that kind of exploration, full of earnest nerds who pair deep technical curiosity with research. My role is to explore important problem spaces, develop conviction, run experiments, and eventually turn the most promising direction into something real. In many ways, it feels like a natural extension of my hobbies and passion projects. I’ll be in SF during the week and LA on weekends. I want to use that time to meet as many interesting people as I can. Let’s get coffee and talk about energy, compute, artificial intelligence, and manufacturing. I want to hear about your most ambitious ideas and deepest technical rabbit holes.

We built a game to demonstrate the difficulty of pacing the frontier, based on a new paper from @andrewjkoh and @DrewFudenberg Play online now and work your way up the leaderboard!

GPU World: A story competition from Neal Stephenson, Gwern, and me. The AI future is unevenly distributed. What would the world look like with AI broadly diffused, such as if we had one GPU per person? 1000-5000 words, fiction or non-fiction. $100K in total prizes. gpuworld.org

Now contracted by Army, Air Force, Space Force to deliver nuclear power @jordanbramble and his team built these reactors for years of off-grid operation

Glad to have @alanapalmedo of Paradigm representing crypto, prediction markets, and AI on the CFTC Innovation Advisory Committee today in DC

Incredible to see Zipline’s momentum in building the autonomy layer of the skies. Uber + Zipline for 1m+ deliveries / day…

How fast can you get AI to build itself? @justinwangx and I built a web game about that, based on real research into recursive self-improvement (RSI) You play a frontier lab investing in R&D, trying to build superintelligence Play RSI Simulator: paradigm.xyz/research/rsi/ga…

Announcing Centaur 2.0! Centaur is frontier, agentic infrastructure that you own. Centaur is like Claude Tag, but open source and on steroids. Centaur 2.0 can connect to everything you have access to, and can reason over it next to where you work, either in Slack, Discord, Teams or in your local Codex or Claude Code via an MCP. But context isn't useful if it can be accessed by anyone, so we rebuilt Centaur from the ground up for security. Centaur obviously doesn't have access to secrets because we're leveraging egress proxies. Centaur 2.0 takes that a step further enabling administrators to configure who can access what from where. This means that Centaur can have access to private information that you normally wouldn't feel comfortable giving it access to (e.g. DMs or sensitive channels and docs) but only expose it to authorized principals. It also means you can add Centaur to external channels and leverage it as a virtual colleague that doesn't live only in your Slack, for example, but also your Slack Connect channels! This is extremely powerful as we start moving to a world where agents cross organizational boundaries. Also in case anyone's wondering, yes we rewrote it in Rust! Centaur is now way way more stable at durably executing threads, and its workflow engine is now based on Absurd. We have been operating Centaur since January, officially launched and Open Sourced it in May, and now we're full speed towards making it the #1 open source agentic infrastructure. To succeed at that, I'm thrilled to welcome @mslipper to the @paradigm team who will be leading all our Applied AI work, while continuing to maintain and extend Iron Proxy as the leading secure secret access for agents. Welcome Matt, it's an honor after all these years of knowing you! Read the full blogpost below, and apply to join our team!

US nuclear capacity flatlined for 40 years but power demand is now surging. @antaresnuclear was the first to achieve criticality on a factory-built advanced reactor. Huge props to @jordanbramble for restoring energy dominance and building reliable power for our military Paradigm is thrilled to co-lead this round

Let's build a formally verified compiler together Collaborative automated research can be an amazing tool for formal verification, and vice versa We're launching two new challenges on @paradigm Puzzles to help complete Solidus: a formally verified Solidity compiler in Lean 🧵

The models are increasingly good at Erdos problems, but some experts like @Qiaoqiao2001 seem to have exceptional skill at prompting We sponsored him to see how far he could go He solved six this week, including one that had been studied by Terence Tao Here’s how he did it:

Frontiers by @Paradigm returns to San Francisco on October 12-14, 2026! Frontiers is our intense annual conference & hackathon for those beyond the edge. No booths, no sponsors, curated audience, stablecoins, ai, robotics, post-quantum cryptography and more. Apply below!

Centaur is open source Claude Tag on steroids. Our most recent release unlocks adding Centaur to external channels, allowing untrusted input. This is a game changer, extending Centaur to a virtual coworker that you can add in any Slack Connect channel. Link below.

$1.2B to invest in steep exponentials 8 years ago we were backed by people who believed in the crypto frontier. Now we’re doubling down as frontiers are colliding across AI, crypto, space, deep tech, energy Grateful to our partners
