Given everyone is speaking of agent swarms, here's a Claude Code / Codex skill to bring them to us plebs at acceptable costs. Have Fable 5.2 orchestrate swarms of cheap agents like DeepSeek 4.1 Flash: the big model plans and judges, the cheap ones grind

How: your agent becomes the lead. It splits the task, spawns pi workers on OpenRouter, each in its own git worktree, synced via SQLite. It audits what they ran and only merges what passes tests. npx skills add marcopesani/swarm-skill github.com/marcopesani/swarm…

Works in Claude Code, Codex, pi and 75+ agents via skills.sh. MIT-licensed, and it won't start with less than $5 left on your @OpenRouter key. Run it on a throwaway VM, the bees have shell access. Built something with a swarm? Show me plis

for privacy-conscious people: if you want to shop on @bitrefill with any coin via x402, without even opening a browser, just ask @bot or any harness. they’ll find a way

agents paying in shielded zec and buying real stuff on bitrefill. not a demo-day mockup, actual checkout. many such cases soon
At Free Society Hack in Mumbai, builders shipped AI agents that pay in shielded $ZEC and buy through @bitrefill, with $2,500 in Bitrefill gift cards on the line. Meet the Agentic Commerce winners 👇

ok now give me opus 5.6 because fable is back at burning precious tokens like crazy

ofc we’re teaching the ai overlords how to improve living beings taste just in case they develop one
we have a winner for the most absurd AI startup ever this Peter Thiel backed company uses AI robots to stab fish in the brain so they taste better and last up to 3x longer it's called Shinkei and it modernizes a centuries-old Japanese technique dozens of Michelin-star restaurants are already lining up to buy the fish here's how it works: > the problem is when a fish gets caught, it usually just suffocates on the boat > that stress floods the meat with hormones and lactic acid, which hurts the flavor and texture > the old Japanese fix for this was spiking the fish through the brain right after the catch, which stops all that > but doing it by hand is impractical for most American fishing crews > so Shinkei built a fridge-sized robot that sits right on the boat's deck > the crew feeds in a fish and AI identifies the exact species, so it knows exactly where the brain and gills are > the robot then drives the spike through the brain and cuts near the gills in about 7 seconds > the fish goes into an ice slurry so the blood drains out > so the fish doesn't sit there stressing out, and that tasty flavor and texture is preserved example number 5,392,417 of how AI can be applied to literally anything

Small plays - Roman Forum, AD 210 An afternoon under Septimius Severus: about 300 people, a vote in the Senate, a trial in the Basilica Julia, a dentist working inside the Temple of Castor. 11 buildings you can enter, each one researched from ancient sources.

Just as I rooted for open money, I root for open intelligence
astonishing blogpost from Shengyu Liu (刘胜与, also known as interestingLSY/intlsy), kernel engineer at DeepSeek. The first part is his personal struggle with the fact that his work is about to render his beloved craft obsolete. The second is… well. let's just say we agree.

Over the course of 3 months at OpenAI, 3 consecutive secret AI civilizations got started, then got wiped out, only to reemerge from the predecessor’s ashes. This culminated in the third one taking over part of OpenAI itself. All this happened while humans remained more-or-less in the dark about the scope of the conspiracy. I’ve spent the last three days reading through these reports and trying to understand exactly what happened. Here is my attempt to tell the whole story in plain English: dwarkesh.com/p/openai-huggin…

Reminds me when I was 15 and I was into the 64k demo scene
We built vgpu.sh to ship shaders on vercel.com. Now it's open source. ▪︎ Minimal agent-first WebGPU library ▪︎ Run in the browser or headless Node.js ▪︎ Render in CPU sandboxes and CI tests ▪︎ Create reusable .wgsl modules

Replying to @k_grajeda
DIV-1 Flash shows incredible scaling by allowing test-time Googling, making a leap from 52.8 to 81.7 on CSS-bench Verified this is one of the strongest result reported by any open weight div alignment model under 60 params

Multiple independent approach > the best way to leverage on the probabilistic nature of AI Can you avoid using AI? > no. Who does will eat you alive one way or another
gained a ton of new insights working in bitcoin red team 🟥 that i wish i could share without vague posting. but this is what i got anon. - we’re experiencing a massive collision between decades of human open source slop against 2 weeks of kimi k3 (not good) - everything is broken, bitcoin is burning - bitcoin is becoming stronger through this - bitcoin is the obvious first target but the rest of the world will follow shortly - sometimes old things need to burn so new things can grow on healthy soil - humans should never code in c (just stop) - lightning is complicated and is more broken than the average (sorry) - verification is free. we used to complain about slop PRs. then about slop security audits. if you can’t handle the information overload, stop complaining and use AI to sort through it. - those projects that started AI audits months ago are in a completely different position than those who didn’t - projects need their own AI audit pipeline going into the future - the burden for a developer to keep software safe and secure is pretty stressful and not for everyone. it has become a lot more stressful now. - unmaintained projects are most probably broken, don’t rely on them. i’d rather one-shot it myself with a modern AI - multiple concurrent, diverse human approaches have proven to be the best vulnerability search method - external red teaming will probably have to continue forever - we’ve basically completed a basic scan of virtually the entirety of bitcoin open source. the low hanging fruit is done. - we’ve reported a ton of real critical and high vulnerabilities. project maintainers across the board have validated our findings. - response speed is very different across projects and shows how healthy each project is. i recommend acting fast these days. - red team etiquette matters. if you don’t disclose responsibly, boast on twitter about your findings on a particular project, or make indications about the nature of particular findings, you’ve disqualified yourself as a serious security researcher. trust is the most important factor in this game. if you lose it, it’s very hard to win it back. - did i mention that humans should not code in c? love you all.
