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 ↓

Demo & Source: Some cool technical details ↓

▪️ The Sandbox is capable of running virtually any programming language and runtime. It's a full Linux box. ▪️ This is a cutting-edge architecture and it incorporates a ton of lessons of what makes v0 good ▪️ GPT-5 is absolutely cracked when you use it right ▪️ @aisdk allows us to switch and optimize for different models. If you fork this, you'll be able to use faster models for part of your agentic pipelines. The future is multi-model! e.g.: the speed at which @groqinc can generate code with open models is absolutely unmatched

h/t @nishimiya and @javivelasco for such a fine cook

@v0 @vercel @OpenAI “Make no mistakes”

@Odiidanny @v0 @vercel @OpenAI 😂

@v0 @vercel @OpenAI how come everyone is shipping similar things at the same time i think yesterday firecrawl also announced their open source lovable must be a coincidence

@v0 @vercel @OpenAI They’re doing good work and we’re collaborating with them too!

@v0 @vercel @OpenAI the sandbox can run any language as backend?

@v0 @vercel @OpenAI Yes

@v0 @vercel @OpenAI woah, so cool

@v0 @vercel @OpenAI damnnnn

@v0 @vercel @OpenAI You could hook it up to @encoredotdev and get infra provisioned as well right from the platform.

@v0 @vercel @OpenAI So why not support OSS on V0 itself? 👀

@v0 @vercel @OpenAI this is awesome

@v0 @vercel @OpenAI One-shot, pretty impressive!

@v0 @vercel @OpenAI This is the new “todo” app

@v0 @vercel @OpenAI Isn't it an expensive workaround? The previous sandbox likely stopped. I’ll create a fresh one, recreate the project, install deps, and start Expo Web on port 19006.

@v0 @vercel @OpenAI We’re working on snapshotting

@v0 @vercel @OpenAI Hell yeah, v0 + Go

@v0 @vercel @OpenAI Can it use Claude Code?

@v0 @vercel @OpenAI Yes. On two levels. ▪️ The agentic loop we wrote is a bit like “Claude Code at home”. It’s tools exposed to @aisdk ▪️ You can also just run `claude` / `codex` / `opencode` inside the Sandbox If you do the latter, make sure the threat model contemplates the api key exposure

@v0 @vercel @OpenAI @aisdk Will check it out.

@v0 @vercel @OpenAI Impressive. Automating the coding process like this could significantly change software development. I wonder about the long-term implications.

@v0 @vercel @OpenAI Those tools to interact with the Sandbox are a gold mine!

@v0 @vercel @OpenAI It uses Vercel Sandbox? big win for me if so

@v0 @vercel @OpenAI But can it run crysis

@v0 @vercel @OpenAI vercel is such an important company

@v0 @vercel @OpenAI multiplayer pong in one shot is impressive but the real test is how it handles state management and error recovery when things break

@v0 @vercel @OpenAI So you don’t sleep, got it

@v0 @vercel @OpenAI @Emmysoft_Tm

@v0 @vercel @OpenAI Would be interested on details on what was changed since the initial release, how the agent loop was enhanced etc.

@v0 @vercel @OpenAI We’ll likely do a tech write up! cc @nishimiya

@v0 @vercel @OpenAI @kartik_builds, can we use this? 👀

@v0 @vercel @OpenAI How does this compromise to Codex extension on Cursor?

@v0 @vercel @OpenAI I would love to use v0 but need a desktop client like cursor, online platforms feel a bit clunky

@v0 @vercel @OpenAI this is awesome!! can't wait to build my $1 trillion/mrr startup 🙏🙏

@v0 @vercel @OpenAI Call it Open v0 🔥

@v0 @vercel @OpenAI Legendary! Will try it and share feedback

@v0 @vercel @OpenAI Lfg 🔥

@v0 @vercel @OpenAI multiplayer pong lol. you need to invest in a marketing team. multiplayer pong shouldnt be the demo unless you trolling

@v0 @vercel @OpenAI

@v0 @vercel @OpenAI it just stops on the first prompt due to credits

@v0 @vercel @OpenAI Awesome!

@v0 @vercel @OpenAI Okay this is another level up. Brilliant

@v0 @vercel @OpenAI 👨‍🍳
