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

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.

When the dust settles, we'll have to talk about the fact that not a single vulnerability was found by a US frontier model. Instead, we're spending $10k a day on open weights models like Kimi K3 and Qwen 3.8 to find vulnerabilities in Bitcoin infrastructure. It's a disaster.

Race to ASI is a winner takes all game, and it always has been
should be obvious by now, but OpenAI and Anthropic are just gonna keep cannibalizing all their biggest customers. it’s simply too profitable for them to resist. and it’s already happening: 1. Figma partnered with Anthropic on AI design tools. then Anthropic’s product chief quit Figma’s board, and 3 days later Anthropic launched Claude Design to compete with Figma. CEO Dylan Field said Anthropic was “not consistently candid.” 2. Novo Nordisk uses Claude to help develop drugs. now Anthropic is developing drugs of its own. 3. Microsoft poured billions into OpenAI. now OpenAI is building a Jobs Platform to compete with LinkedIn, and reportedly a code repository to compete with GitHub. Microsoft owns both. 4. Harvey uses Claude to sell AI contract analysis, due diligence, and litigation tools. now Anthropic sells those same workflows through Claude for Legal. 5. Intercom used OpenAI’s Realtime API to build Fin Voice. now OpenAI sells its own voice-and-chat support agent through Presence. 6. Abridge and Ambience build clinical documentation products on OpenAI. now OpenAI sells ChatGPT for Healthcare directly to hospitals with clinical documentation built in. 7. Benchling uses Claude to power its biotech R&D platform. now Anthropic sells its own scientific workbench through Claude Science. the frontier lab playbook is simple: 1. sell their models to the world’s most valuable businesses 2. help wire them into those companies’ most valuable and sensitive work 3. map the business from the inside and find where AI can take over 4. turn those capabilities into their own products and become the customer’s competitor

It's like OpenUltimaOnline. My 16yo self can't wait to play, hack, and build on it.

My test of Kimi K3: one prompt to the @Kimi_Moonshot K3 Swarm, a longform tribute to the history of @TorinoFC_1906, the club I love. 5 hours unattended, mostly one-shotted, a few follow-ups for layout glitches.

The page is live, judge it yourself: grandetoro.kimi.page/ For context: K3 scored 1,679 on the Frontend Code Arena, beating Fable and 5.6 Sol. Kimi K2.6 is 18th on the same board.

As a designer I waste hours rebuilding the same references by hand. Fonts here, colors there, never in one place. 😤 So I'm building Inspotype: branding projects broken into fonts, colors and images, one click to remix them on a canvas. Premium foundry fonts included. V2 soon🔥

Your agent can swap, bridge and trade onchain all day. But can it top-up your phone, or get you dinner? Now it can. Bitrefill is live on Base MCP. Your agent can access 10K+ brands, eSIMs and prepaid cards across 180+ countries. It fills the cart, you approve the purchase.
New skills just dropped on Base MCP 13 apps, and now more ways for agents to: → Transact → Trade → Lend → Mint → Buy All onchain, all on Base
