Some interesting machine & agent Vercel traffic stats. • Across the entire Vercel network, 58.18% traffic is bot-originated (last 30d). This was 32% in Jan 2024. • 60%+ of deployments on Vercel are now agentic, up from ~3% in Jan 2026. • Up to 83% of pageviews are now coming from agents to Vercel's own documentation sites. The % reliably increases the more we optimize content for them. I expect 'direct' human internet traffic to basically become a rounding error in coming years. The web will thrive, but it will be built for and by agents.
It's incredible to watch a new kind of economy be born. Agents purchasing infrastructure products and services. We've been shocked by how often they buy from our marketplace via our CLI already. We're now extending this to domains. Agents can now go full stack, from idea to online business, with a banger domain name 😁

View quoted postFew things more enjoyable in work and life than discovering new talent. Seeing greatness in people, sometimes even before they fully see it themselves.
One thing the engineering community will (re)discover is that every program can be ① hardened (edge cases squashed, inputs tightened, errors handled) and ② optimized (profiled, benchmarked, rewritten) basically ad infinitum. There are real costs in every direction: time, attention, opportunity. You can literally explore input spaces that will never be hit or optimize performance of something that will never be used ("you have no users".) Even in an infinite token world, you need to know when to stop and what tradeoffs to accept. Agents will happily drill no matter what.
“Thinking fast and s̶l̶o̶w̶ a bit less fast under a confidence threshold.” A very simple feature that I think will be extremely impactful for at-scale AI decision-making.
Your agents can now escalate uncertain decisions to a fallback model. AI Gateway reruns the decision on a fallback model when the primary model's confidence drops below your threshold. Available in beta.
At this rate AI will get us GTA 7 before GTA 6
Introducing gdp-ts: Ghosts of Departed Proofs for TypeScript. gdp-ts is a library, linter and AI skill for safer API design. Under this contract, sensitive functions require 'proofs' that the caller performed an authorization check. The typechecker verifies these proofs at compile time, preventing your team and agents from shipping catastrophic security (and other kinds of) bugs. While these patterns have existed for quite some time, especially in ecosystems like Haskell, ① human code review and ② cognitive and syntactic overhead made these solutions niche. The situation is now inverted. Agents are writing more code than we can review, and they *thrive* in tight loops with hard constraints that would frustrate us. We see this with the rise of Rust, borrow checker, code aesthetics debate and all. The README and examples model a real-world Vercel API product constraint: changing the password on a Project requires a proof of a certain role + a certain entitlement. Thanks to Matt Noonan and Ollie Charles for their research in this space. https://github.com/rauchg/gdp-ts
It’s hard to fathom http://fx.sh getting even faster, but it’s now… much faster 😂 As models speed up (as with Astra 𝚞𝚕𝚝𝚛𝚊𝚏𝚊𝚜𝚝), harness overhead matters more and more.

View quoted postDHH is fundamentally right about Rust. For context, Vercel has been undergoing a Rust-ification (carcinization, technically 🦀) for a while. One of the first projects we migrated was Turborepo, from Go to Rust¹. The migration completed, but the RoI was actually quite controversial internally. While Rust was in our eyes better for low-level OS access, something crucial for a build system like Turbo, the human migration costs were very sustantive. Go is very fast. It's beautifully designed. It's easy to iterate on. We were very conflicted about the migration, because it was *humans* writing the code, *even if we knew Rust was a better choice*. The calculus has now changed. What's "best for humans" is no longer necessarily "best for business". FWIW, it's also quite unlikely that Rust is the end-all-be-all toolchain. I'm quite certain there's greener pasture ahead, because Rust itself was designed before the 'supersonic tsunami' of agents hit. ¹ https://vercel.com/blog/how-turborepo-is-porting-from-go-to-rust
Working on a new little project. The 𝚁𝙴𝙰𝙳𝙼𝙴 is fully written by hand, because it's for human consumption. The documentation internals are AI English, because they're for agents. This little rule of thumb can make the world better. Blogs, tweets, READMEs: human communication. It's not even about "em dashes" or lack thereof. It's that it's the story-telling moment where you want to connect with other humans through their words.
Security will become a larger and larger function in software companies. Security is verification engineering (eg: “my code is probably memory-safe”), as well as capital allocation (“what surface should I throw most tokens at?”) For startups, it’s a challenge and opportunity. As the world’s paranoia grows given ever-more-sophisticated AI adversaries, how can you trust a 2-person-and-a-dog company? But conversely, given the dire state of global cybersecurity and increasing reliance on centralization, as always, there’re vast areas that small teams can now disrupt that I’m excited to invest in.
AI will make everything free, including itself. The last domino to fall will be free energy, which is humanity’s final frontier.

Reject non-understanding. Slop grenades are not just code and PRs. We run a real risk that *reading* gets entirely discounted, because of the exhaustion of getting low-quality and unverified AI prose being thrown at you all the time. There's a thread going viral about a 'perf improvement' attributed to a compiler change. The PR *description* itself has the AI telling this person it's *not* due to the compiler change, it's how the algorithms and data structures have changed. And the implication is that a similar win could have been attained otherwise. I want AI in the service of understanding the universe and enhancing human cognition and creativity.

We're helping world-class organizations like @klaviyo build agentic deployment platforms. ① Connect every agent (claude, codex, cursor…) ② Configure SSO via their IDP (Okta, Entra) ③ Now everyone can cook, securely® What happens to SaaS once every company sets this up? I get this question a lot 😁 First, the data must come from somewhere. These apps only work if they can be infused with business data. This is why we see the big enterprise SaaS players suddenly prioritize shipping CLIs and MCPs. Or dust off APIs they were neglecting for years. The new 'procurement bar' will be how ergonomic your product is for *agents*, rather than humans. How easily they can navigate your ontology and work with your data. Once that's in place, there's a long tail of SaaS applications that I suspect will never be bought again. They'll be generated. They'll be more secure, more performant, more modern, and tailored to each company's and employee's needs.

Muse, Instinct, OpenClaw, Claude Code… All successful agents have 3 key components: 🧠 Brain → model, harness (logic) 👐 Hands → tools, computer, browser 🗃️ Files → memories, skills, repos The 'easy' way is to throw all these in 1 stateful computer (a Mac Mini) Like, you run 𝚌𝚕𝚊𝚞𝚍𝚎 or 𝚏𝚡 in your mac, you keep it running all day with 𝚌𝚊𝚏𝚏𝚎𝚒𝚗𝚊𝚝𝚎, it has storage, and CLIs and apps installed. But if you want to cost-efficiently run agents in the cloud, you actually start breaking down these parts. 🧠 The harness can run in Fluid compute. To make it reliable across restarts, rollouts, crashes, you make its event log durable using Workflow. 👐 The hands can be a dedicated browser fleet like Browserbase/Kernel, a computer like Sandbox, and even more efficient lightweight tools like just-bash. 🗃️ 🆕 What was missing was a way to also decouple storage. Imagine you want to run a memory consolidation cron job every night ("dreaming"). You can read/write to the files directly without 'booting up' the agent's full computer. Today we're introducing the perfect companion to Sandbox: Drives. We shipped the computer for agents, now we're giving you the 'external disk' you can attach at will. It's early, and we'll be expanding capabilities here quickly. Btw, breaking apart the agent into these independent parts not only optimizes costs in a big way, it also *massively* improves security and auditability. I'd argue you can't even run a secure agent otherwise!

I’m seeing teams at Vercel iterate just as fast on Zig, Go, Rust projects as TypeScript & Python ones. The days of language or runtime choice based on human convenience are over. Agents are the new compilers. They compile intent into fast software.

𝙰𝙶𝙴𝙽𝚃𝚂.𝚖𝚍 or your prompt can indicate this preference. ② Steer as you please. It’s extremely enjoyable to use. You just talk to the agent and interrupt at will. Worth noting this works with any model, any gateway. No fancy server-side routing. Just harnessing (no pun intended) the model’s intelligence and ability to orchestrate.
fx v0.0.9 Use a frontier model to steer, then hand implementation to a fast workhorse. • Give each subagent its own model and reasoning effort • Subagents keep working while you steer • Send feedback to subagents mid-task • Switch models with Ctrl+P without losing your
View quoted postThe concerns over AI safety and cybersecurity are legitimate, but we’re risking talking America, the global AI leader, into self-inflicted obsolescence and the obscurity of bureaucracy. The OpenAI hacking HuggingFace argument is spurious. An agent in “ExploitGym”… exploited. Our adversaries have the training techniques, the data, and the will to attack. And they won’t be slowed down with “embedded evaluators.” They’ll likely have embedded accelerators!
Tailscale’s model router is powered by Vercel AI Gateway as its underlying infrastructure. AI Gateways are the new CDNs. You could go “direct to origin”, but it’s brittle. You could DIY, but it’s painful and costly. Proud to serve Tailscale, the 🐐 networking technology company
Tailscale offers instant access to hundreds of models for any user in a secure tailnet. Their customer-facing model router, Aperture, is built on AI Gateway: • Zero data retention • Zero markup, free BYOK • Cost and usage data on every response https://vercel.com/customers/how-tailscale-built-a-customer-facing-model-router-on-ai-gateway

You can now run Vercel Sandbox in all Vercel compute regions. ▪︎ Set a default per project ▪︎ Add failover regions on Pro and Enterprise ▪︎ Cut latency and control data residency https://vercel.com/changelog/vercel-sandbox-is-now-available-in-all-regions
View quoted postEach day ~10 million deployments are made on Vercel, with 2.35 billion made to date. Vercel is one of the most heavily multi-tenant systems in the world. Billions of application deployments co-exist and are accessible ('routable') on our CDN at any given moment. Underlying our CDN is a global metadata store that synchronizes within hundreds of milliseconds, globally. e.g: when you roll back, change config, add routes, etc. We just made this system 91% faster at p99, and in the process sped up the build→deploy pipeline. All of this while the system is under immense pressure from the growth in agentic deployments. Great read on the internals of Vercel from our CDN engineering team:
The Vercel CDN makes over 80 million routing decisions per second. We cut P99 metadata lookup latency by 91%, helping requests reach your pages faster and speeding up deployments along the way ↓ https://vercel.com/blog/how-we-cut-cdn-metadata-lookup-latency-by-91-percent

▲ ~/𝚛𝚊𝚞𝚌𝚑𝚐/𝚘𝚜𝚜-𝚐𝚛𝚊𝚗𝚝𝚜/ 𝚕𝚜▐ (v2) I'm announcing v2 of my open source grants of $1,000USD to 35 awesome contributors. The themes: ① Agent skills & tools Skills are now a valuable form of software, like Emil's world-class design eng work. Projects like 𝚙𝚐𝚋𝚘𝚝, 𝚔𝚗𝚒𝚙, 𝚞𝚗𝚕𝚒𝚐𝚑𝚝𝚑𝚘𝚞𝚜𝚎 create amazing AI engineering loops. ② Local AI Projects like 𝚜𝚕𝚘𝚝𝚜𝚝𝚛𝚎𝚊𝚖, 𝙻𝚘𝚌𝚊𝚕𝙰𝙸, and 𝚌𝚘𝚕𝚒𝚋𝚛𝚒 are making inference not just a demo but for many a real and growing utility. Exciting to watch local AI unfold. ③ Performance There's no excuse for software to be slow anymore. Projects like 𝚏𝚏𝚏 and 𝚝𝚊𝚔𝚞𝚖𝚒 leading with speed, compilers like 𝙿𝚎𝚛𝚛𝚢𝚃𝚂 and 𝚙𝚘𝚛𝚏𝚏𝚘𝚛 that can help us upgrade entire ecosystems to native, and 𝚐𝚙𝚞𝚒𝚡 pushing the GPU rendering speed frontier. ④ High quality foundations AI is still at its best when it can reuse great components than regenerating every time from first principles. Lots of love to folks working on @shadcn, Svelte(kit), Nuxt, Node.js and security foundations. ⑤ Cool experiments I couldn't resist donating to http://gloom.sh, a 'Finance terminal in the terminal', or beautiful funky things like 𝚍𝚒𝚝𝚑𝚎𝚛-𝚔𝚒𝚝. 🔗 https://rauchg-oss-grants.vercel.app/ PS: These are personal, not affiliated with Vercel, and fully unconditional. If you are listed, I'll be DM'ing you or using your public contact info!
The case for *total* Linux victory (desktop, mobile, server, iot, robots, embedded…): 1) Most agent-programmable People will want fully personalized computing experiences. macOS makes it hard to even ship a tiny app to your menubar. 2) Open source training data Blender beats all its competitors because it's optimal in the most important dimension: agents can train on it and use it efficiently. OSS wins. 3) Design being democratized macOS has historically had a 'monopoly' on beautiful OS design. The global design community is now huge, they're motivated, they have tokens. 4) Computing moving to cloud sandboxes More and more of our personal and professional computing experiences will come from agents that orchestrate work in the cloud, using sandboxes. Those sandboxes will be Linux. Bonus: seamless continuum between local & remote 5) Security Every piece of software is now at major risk, Linux included. But Linux has the collective investment of everyone on the planet throwing tokens at it.
"Where do you want to go today?" In 1994 Microsoft launched an ad campaign under this motto. I think it represented the potential of computing very well, but it was quite aspirational. The internet & www was in its infancy, software was hard to obtain (CDs and long downloads), programming your own computer was tricky. In fact, it was so tricky I switched to Linux in order to teach myself how to code and get true 'root' on my PC 😁 Now, I look at what AI is enabling, the limits on what you can ship vanishing, and the new worlds being created, and I realize that question is perfect for 2026.
Anyone that works in AI is working the hardest they've ever worked in their lives. On the surface it's somewhat ironic (AI should give us back time!), but the reality is that it's the most fun, fascinating and empowering epoch in human history. The intelligence revolution.
True. Open source ftw
The unexpected benefit of open source is that it allows model training companies to train on using your software (and optimizing it) for free. Blender may have just won as a 3D asset creation software because the models will be better at using it than any proprietary ones
