Vercel AI Gateway now supports video generation. Grok Imagine Video & Image are 🆓 until tomorrow. We used v0 to create an open source Creative Studio powered by xAI Grok. Create images, videos, or make your own design tool! – it's quite fast. Some cool technical tidbits: ▪️ Vercel Workflows for reliable generation Video generation can take long. Users might restart their browsers or their wifi / LTE might drop. We smooth over that automatically. ▪️ Instant vector search Try searching the public generations. Now back to me. We used Mixedbread to index the content visually, so you can search 𝚋𝚕𝚊𝚌𝚔 𝚏𝚎𝚕𝚒𝚗𝚎 and get a cat (try it!) ▪️ Vercel AI Gateway All existing and future Grok models are accessible via our gateway without extra setup. When you deploy to Vercel, you get access to hundreds of models with a single account and unified billing It's obviously built with Next.js (RSC). Open it in v0 to make it your own! h/t Esteban Suárez for shipping this.

Spend of OpenAI vs Anthropic vs Open (Vercel AI Gateway, last 2 months) • Anthropic still #1 in spend, but went 69% → 40% • OpenAI: 10% → 24% in spend • GPT-6 Astra + GPT 5.6 Sol are ripping • OpenAI now leads in tokens # • Kimi K3 + DeepSeek took ~half of Anthropic's loss • Opus 5.5 is up to 10% of spend in 2 days • OpenAI is 62% of image generations Watch here:

I¹ ported my Mini web browser to Rust & Swift. It's faster, more secure, and shockingly, nicer to iterate on than Electron + Bun. I always wanted Safari-like UX but… Chrome 😁. Thanks to the 𝚌𝚎𝚏 crate, I can bundle up-to-date Chromium. 𝚏𝚡 𝚊𝚌𝚙 lets me embed an agent without bloating the app. It talks to my local fx CLI over ACP. fx can then manage the browser via an MCP server². By ditching Electron, I was able to get Liquid Glass, faster boots, and a more Mac-native feeling. Little things like fine-grained focus and input control, which are nightmare fuel in JS, just work®. Native is the future, both on the desktop and in the cloud. I suspect the entire software world will "nativify" faster than people realize, as DHH hinted at Rails World. Excited that Vercel's bet on Fluid will help support this, whether you choose to go Rust, Go, Zig, scriptc… ¹ Built on with Opus 5.5 and Sol 6 ² In the process I learned about which I'm now really excited about. This will allow a more secure and direct way to expose MCP tools

Created a flag on the moon based with hyper-realistic physics with v0: The flag is simulated as a grid of particles connected by springs (cloth simulation). It's influenced by gravity, wind, air resistance. The initial approach v0 one-shotted was quite simplistic, but giving it references to more sophisticated approaches in C++ and Rust quickly improved it. It was mind-blowing it to see it deeply understand the physics and port new ideas across languages. It simulated a real sun for lighting, and procedurally generated moon-like terrain with craters. I found a sick free texture on Reddit that I uploaded and it layered on top. Another epic moment was watching it improve performance. It seamlessly moved the physics simulation to a Web Worker. (Kinda cool to see given we just improved support for them in Turbopack 😉)

🏁 I animated the token 💰 spend race, from ~lifetime Vercel AI Gateway usage, which aggregates trillions of tokens from millions of developers a month. Fascinating to see the fluctuations among the labs, Anthropic's dominance, and the rise of open weight AI.

We shipped an OSS 'vibe coding platform' (like v0) built with Vercel AI SDK, Gateway and Sandbox. We worked with @openai to tune the GPT-5 agent loop. It can write/read files, run commands, install packages, autofix errors… Demo oneshotting a multiplayer Pong in Go ↓

I used 𝚏𝚡 to build Mini, a personal web browser. Many times I need to screen share, stream, or just test something without the 'bloat' and state of my browser. So I go Mini. This was a cool test for and open models. It was the first time I experienced how cheap, but also how *good* these things can be. 'Personal software' is a hot topic. "I spent $25,000USD to cancel my $10 XYZ subscription" is a real thing 😂 (especially in Enterprises these days). But I think open and local models will change this dynamic very profoundly. Software will really become spontaneous. ps: shoutout to Orion browser who inspired me with 'focus mode'. I wanted my browser to be even more minimal, hackable, and run on Chromium.

If your terminal ever gets into a 'bad state', like garbled outputs, you run 𝚛𝚎𝚜𝚎𝚝. I noticed it was… oddly slow. Turns out in 1979 3BSD's 𝚝𝚜𝚎𝚝 had a 𝚜𝚕𝚎𝚎𝚙(𝟷) to let mechanical printer-and-ink terminals 'settle down' 😂 I asked 𝚏𝚡 to write me a faster alternative in Zig. It takes 1ms instead of 1s. It was really cool to dive deeper into 𝚗𝚌𝚞𝚛𝚜𝚎𝚜, 𝚝𝚜𝚎𝚝, 𝚝𝚎𝚛𝚖𝚒𝚗𝚏𝚘, and the myriad ways in which your terminal can get… cursed. It's legit fascinating how far back our technology stack goes, and how enduring good system design is, even with the occasional 'spider webs' you can find. Check out for a fun explainer (and some alternative solutions.) ps: once you start using 𝚏𝚡, you'll notice slowness like this everywhere :D

Can ChatGPT run Doom? Yes. ChatGPT Apps are very powerful. I cloned our Next.js ChatGPT template, registered a 𝚙𝚕𝚊𝚢_𝚍𝚘𝚘𝚖 MCP tool and deployed to Vercel. Once the tool is called, ChatGPT embeds the full Next.js application. Server and client rendering just works, and it's 100% interactive. h/t Allen Zhou for the starter kit:

I started the Next.js you know today from a 𝚁𝙴𝙰𝙳𝙼𝙴.𝚖𝚍 specification. That was the singular commit that set it on the trajectory you see today. We proceeded to furiously write code for weeks as we saw a unique window to disrupt the React ecosystem, which primarily consisted of "boilerplate" repos and static-only tooling. I now believe most software (and companies) will start out as markdown files, but it's agents that will be doing the furious coding. And the releasing. And the maintenance. I'm pretty happy that the API we laid out is as relevant as ever today. It's simple, filesystem focused, and its principles remain unchanged.

The future of design is… engineering. All designers at Vercel now also build, thanks to tools like v0, Claude Code, and Cursor. They've been contributing to our frontends and apps for a while now. But over the past few months, the leap they've made is engineering the design process itself by building agents. A big part of shipping is getting the word out in a compelling way, especially on the X platform, the everything app. In the past, we used to spend a bunch of time hand-crafting images and illustrations for social cards. Our design team built an internal agent and web ui using v0 and Claude Code that makes this process fully self-serve. It even includes a previewer of what the final artifact will look like on X. It's called Leap. It's probably saved us hundreds of hours of work but also massively raised our quality bar. The artifacts it produces are beautiful. If you had asked me even 12 months ago whether our design team would be building their own design tools, let alone be this good, I would call bs. There was no master plan, or God forbid, a "sprint" to make this happen. It just took a handful of prompts to build and it propagated on Slack. Leap is now one of the many agents that helps us run our company more smoothly, built and securely deployed on Vercel for our internal use.
