    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 ↓

    We just shipped vision for @v0 — generate React, Tailwind, and Shadcn UI from an image! If you’re still waitlisted, reply here with a use case for v0 vision.

    Built an Agent Builder in @v0 Image and text models, javascript, export to code, conditionals, and API requests are all supported. Zero code written.

    I re-interview our best performers. I set time aside to understand why they ramp faster, ship faster, understand customers better. Recently I got one of the best compliments about our organization. This engineer came from a really good startup. He joined when they were 20

    Use labelled if statements to avoid deeply nested blocks when performing a lot of checks
    A screenshot of JavaScript code (verbatim below) that showcases labelled if statements, with "break <labelName>" used to shortcircuit an if block.

Code:

let value = undefined;

getValue: if (someBoolean) {
  const response = await fetch("...");
  if (!response?.ok) {
    break getValue
  }
  
  const json = await response.json();

  if (!json.someProperty) {
    break getValue
  }

  value = json.someProperty;
}

    There's a few bugs and a lot more I want to do, but my Minecraft-in-@v0 is coming along pretty well - Breakable and placeable blocks - Torches and glass - Tree and terrain generation - Basic inventory - And now, sounds!

    An AI chat bot rendering rich components using @OpenAI functions, @nextjs Server Actions, and the @vercel AI SDK. This is going to unlock so many insanely cool interfaces.

    We just released a new demo of the Vercel AI SDK showing off streaming LLM responses in React Server Components - Streams and renders without additional JavaScript - Dynamic on the Edge, rendering every request - Available as <Tokens /> in the SDK

    When v0 first launched, gpt 3.5 had no knowledge of shadcn or new versions of Next.js So we made a pre- and post-processing pipeline that combines frontier LLMs with our own autofixer model for common mistakes. I’m excited we’re finally able to share some details

    Under the hood of v0’s composite model. v0 is built with custom models and knowledge tuned for React and web development, paired with pluggable, state-of-the-art frontier models. Here's how we build and evaluate it. vercel.com/blog/v0-compos…

    Yesterday I used v0 to build an ABC storybook generator with Google Gemini’s new native image gen I made small tweaks and sometimes guided it, but v0 did all the heavy lifting Oh, and its practically free to run while Gemini is experimental. Link to the site + chat at the end
