Got something new ✨ Introducing Hoast – an easy way for you to manage events and your guests. A single source of truth for you to track who's bringing what to your events. Here's a buggy working demo 😅, thoughts?

AI SDK now supports agent harnesses like Claude Code, Codex, and Pi with sandboxed sessions and AI SDK-compatible streams: 𝚌𝚘𝚗𝚜𝚝 𝚊𝚐𝚎𝚗𝚝 = 𝚗𝚎𝚠 𝙷𝚊𝚛𝚗𝚎𝚜𝚜𝙰𝚐𝚎𝚗𝚝({ 𝚑𝚊𝚛𝚗𝚎𝚜𝚜: 𝚌𝚕𝚊𝚞𝚍𝚎𝙲𝚘𝚍𝚎, 𝚜𝚊𝚗𝚍𝚋𝚘𝚡: 𝚌𝚛𝚎𝚊𝚝𝚎𝚅𝚎𝚛𝚌𝚎𝚕𝚂𝚊𝚗𝚍𝚋𝚘𝚡(), }); Available in canary: 𝚗𝚙𝚖 𝚒 𝚊𝚒@𝚌𝚊𝚗𝚊𝚛𝚢. We welcome your feedback as we bring agent harness portability to the ecosystem, with excellent DX. vercel.com/changelog/program…

Introducing annotations in v0. Click elements in your preview, add comments, then send them all to the agent as a single prompt.

The biggest summer in soccer (err… fútbol) starts today. Build the best soccer app, game, or agent with v0 and win $1,000 in credits. Reply with your creation by June 19.

Flat Rate CDN is in Limited Beta for Pro teams. You pay a fixed monthly fee for Vercel CDN usage, with no overages for viral spikes, unfiltered bots, or misconfigured routes. Join the waitlist ↓vercel.com/changelog/flat-ra…

All firewall-mitigated traffic is now free on Vercel. Starting today, you aren't charged for requests that are denied, challenged, or rate-limited by Vercel Firewall. This extends free DDoS mitigation to rules you configure. vercel.com/changelog/web-app…

The new Vercel CLI 𝚏𝚒𝚛𝚎𝚠𝚊𝚕𝚕 command brings firewall configuration to the terminal. You and your agents can now manage custom rules, IP blocks, system mitigations, Attack Mode, and more: vercel.com/changelog/manage-…

Introducing v0 Browser Use. v0 can now open the apps it builds, use them, critique designs, debug complex flows, and fix things proactively. While it's working, v0 will send you screenshots of what it sees.

Vercel CLI now supports native curl commands. Same syntax as 𝚌𝚞𝚛𝚕, but uses Vercel auth to test all of your deployments. vercel.com/changelog/use-nat…

I wish I could view codex on my phone 🚶🏿‍♂️

I just got $10,000 AI Gateway credit from @vercel to support the growth of my OSS projects... Hard to put into words how huge this is🥹

Introducing Files SDK A unified storage SDK for object and blob backends. One small, honest API. Web-standards I/O. An escape hatch when you need the native client. → 18 providers - S3, R2, Vercel Blob, Google Drive, etc. → upload, download, head, delete, copy, list, url → Works everywhere - Node, Bun, Deno, edge runtimes, browsers → Tools for OpenAI, Vercel AI and Claude Agents SDKs

Midday is joining Ramp We started Midday to build something we wanted for ourselves and it grew into something much bigger than we expected. And here is the story behind it 🧵

تايب سكربت تتخلى رسمياً عن جافاسكربت. الإصدار القادم (7.0) تمت إعادة كتابته بالكامل بلغة Go، وسرعة الـ Compile تضاعفت 10 مرات. لسنوات، كان الـ Compiler الأساسي (tsc) مكتوب بـ TS نفسها ويشتغل على بيئة Node.js. هذا كان قرار استراتيجي ممتاز في البداية عشان يقنعون المطورين يتبنون اللغة، بس هندسياً؟ كان كابوس للمشاريع الضخمة. الـ JavaScript بطبيعتها Single-threaded، ومقيدة جداً في عمليات الـ CPU المكثفة. في المشاريع الضخمة، لما الـ Codebase يتجاوز مليون سطر، الـ Build time يصير كارثة. المطور يغير سطر كود في واجهة معينة ويروح يسوي قهوة لين الـ Type checking يخلص. الانتقال للغة Go (Native port) نسف هذي المشكلة تماماً. اللعبة هنا في الـ Multi-threading. مترجم اللغة صار يستغل كل الـ CPU Cores في جهازك دفعة واحدة (عبر الـ Goroutines). كودك الكبير يتقطع ويتم تحليله بالتوازي. الـ Overhead حق محرك V8 اختفى من المعادلة. التأثير مو بس في راحة المطور. في بيئة الـ Enterprise، هذا يعني أن الـ CI/CD Pipelines في السيرفرات بتخلص أسرع بكثير. فاتورة الكلاود لعمليات الـ Build رح تنزل بشكل ملحوظ للشركات.

Introducing AI CLI Generate images, video, and text from your terminal. Pipe them together. Works with any agent. ai image "sunset" | ai video "animate" → Hundreds of models → Multi-model comparison → Inline previews, no native deps → AI SDK AI Gateway

Seedance 2.0 is now on AI Gateway. Generate photorealistic, multi-shot videos. Try it: 𝚊𝚠𝚊𝚒𝚝 𝚐𝚎𝚗𝚎𝚛𝚊𝚝𝚎𝚅𝚒𝚍𝚎𝚘({ 𝚖𝚘𝚍𝚎𝚕: '𝚋𝚢𝚝𝚎𝚍𝚊𝚗𝚌𝚎/𝚜𝚎𝚎𝚍𝚊𝚗𝚌𝚎-𝟸.𝟶', 𝚙𝚛𝚘𝚖𝚙𝚝: '𝙱𝚕𝚊𝚌𝚔 𝚝𝚛𝚒𝚊𝚗𝚐𝚕𝚎 𝚣𝚒𝚙𝚜 𝚊𝚌𝚛𝚘𝚜𝚜 𝚘𝚏𝚏𝚒𝚌𝚎' })

GPT-5.5 literally changes the game I've tried making this work with so many other models and never got this far. One prompt in, the physics worked. The animations worked. GPT-image-2 generated the backgrounds. A few lazy follow-ups later, Mochipuff was born.

Introducing Tolaria! 💧 Today I am releasing a macOS desktop app for managing markdown knowledge bases, and helping both AI and humans operate them. It’s free and open source, and always will be. I have been working on it for three months, and I now use it to run my life and work. I personally have a massive workspace of 10,000 notes — the result of 6 years of Refactoring — which I now operate on Tolaria. Tolaria is the main collaboration surface with my AI agents: they create new notes there, connect them to what exists, and edit existing ones. Everything is easy to understand for them, because it’s just markdown files. In a way, it’s my implementation of @karpathy's LLM wiki. Tolaria is also the biggest experiment I have ever run about writing software with AI: • 2000 commits • 100K lines of code • 3000 tests / 85% coverage • 9.9/10 code health • 70 architecture decision records I am releasing it open source also to use it as a living artifact of how I do AI coding, so you can inspect at any time things like how I write docs, what's in my AGENTS file, what hooks do I run, and so on. You can find it below: • Newsletter announcement: refactoring.fm/p/introducing… • Website: tolaria.md/ • Github repo: github.com/refactoringhq/tol… Let me know your thoughts!
