Each day brings us closer to opening the waitlist for our first developers. Want early access to our agent platform? Join the waitlist. first come, first served.

We've been quiet for a few days, the team is heads down building. Most AI coding tools today are single-player. We think the future is collaborative, and we’re building the platform for it. More soon. Get on the waitlist: guild.ai

our thesis from the beginning has been simple: Bitcoin mining was the blueprint. Financial engineering across the energy value chain (i.e. durable leverage points) is where defensibility come from. @Melt_Dem and i believe that whoever manages that volatility becomes the “embedded finance layer” of modern energy.

One of the most exciting new AI companies is @SakanaAILabs in our opinion. Their CTO and their Co-founder @YesThisIsLion Llion Jones is now saying it's time to move beyond transformers even though he was one of the 8 original inventors at Google. They are now investigating the next significant step forwards, and have a NeurIPS 2025 spotlight paper called "continuous thought machines" (CTM) which may well be just that (first author @LearningLukeD). They just landed their Series B, with the legendary @hardmaru as their CEO. They are actively investigating neuroevolution approaches which I strongly believe will be a big part of the future of AI -- and they publish their research in the open. Keep an eye on Sakana! 👌 Interview with Llion and Luke dropping today on MLST.

September, 26: Cloudflare rewritten in “memory safe” Rust. The change is touted as “faster and more secure” because of Rust. blog.cloudflare.com/20-percent-int… November, 18 (53 days later): Cloudflare has a massive outage, which took down large portions of the Internet, because of a memory error… in that Rust code. blog.cloudflare.com/18-november-20…

I have no idea what to name my baby At this point I'll just name him "utils"

Ghostty 👻 devlog video: I'm working on search! Here's 15 minutes of me explaining why it has taken so long, what is hard about it, the architecture we're going for, and the big progress I've made recently. Progress PR if you'd rather read stuff: github.com/ghostty-org/gh…

Turns out you can communicate across containers via 63-bits of available space in a shared lock you acquire on /proc/self/ns/time that all processes have access to. No networking required. The post has a demo of a chat app communicating across unprivileged containers.

LLMs are injective and invertible. In our new paper, we show that different prompts always map to different embeddings, and this property can be used to recover input tokens from individual embeddings in latent space. (1/6)

Are premier LLMs truly safe from evolving multi-turn attacks? Our new framework, PLAGUE (Plug and Play Lifelong Adaptive Generation of Exploits), automates adversarial prompts—jailbreaking Claude Opus 4.1 at 67.3% ASR and OpenAI o3 at 81.4%. Vulnerabilities persist! 🧵1/7

🔺iPhone models announced today include Memory Integrity Enforcement, the culmination of an unprecedented design and engineering effort that we believe represents the most significant upgrade to memory safety in the history of consumer operating systems. security.apple.com/blog/memory-in…

GPT-5 just casually did new mathematics. Sebastien Bubeck gave it an open problem from convex optimization, something humans had only partially solved. GPT-5-Pro sat down, reasoned for 17 minutes, and produced a correct proof improving the known bound from 1/L all the way to 1.5/L. This wasn’t in the paper. It wasn’t online. It wasn’t memorized. It was new math. Verified by Bubeck himself. Humans later closed the gap at 1.75/L, but GPT-5 independently advanced the frontier. A machine just contributed original research-level mathematics. If you’re not completely stunned by this, you’re not paying attention. We’ve officially entered the era where AI isn’t just learning math, it’s creating it. @sama @OpenAI @kevinweil @gdb @markchen90

Tool for running Linux containers with lightweight virtual machines on Mac using Swift

Here quick details: x.com/ivanfioravanti…

Can't wait to be able to run containers out of the box on any OS github.com/apple/containe…

Looks like macOS is getting a built-in way to run containers with a `container` command.

"container is a tool that you can use to create and run Linux containers as lightweight virtual machines on your Mac. It's written in Swift, and optimized for Apple silicon." github.com/apple/container Congratulations @crosbymichael @ehazlett @MadhuVenugopal!

Containerization is a Swift package for running Linux containers on macOS github.com/apple/containe… (news.ycombinator.com/item?id=442293…)

📢 Apple Announces Foundation Models and Containerization frameworks, etc. #veille apple.com/newsroom/2025/…
