then we pushed for the wow factor
"I'm hungry" → companion orders a real pizza. IRL
via x402 stablecoin rails on @solana , acting as pizza resellers through Uber Eats via Browser Use.

Gaming has always been about who you play with.
AI doesn't change that rule it finally lets you break the ceiling on it.
- Not here to automate your game.
- Not here to play it for you.
Here to ride with you. To make the same map feel completely different depending on who's in the seat next to you. That's the door that's never existed before, a new creative medium. That's what we're building.
Come meet me and @phan_xyz during GDC all week (Mar 9–16). DM me if you want to talk.

For the in-game UGC, we discovered BuilderGPT, where they simply fed ChatGPT-5.2 @OpenAIDevs a carefully crafted system prompt that instructs it to output straight JavaScript code, instead of heavy JSON blocks, to procedurally generate and fill in the target areas.
@phan_xyz made the whole thing come together beautifully, integrated it into our own project so companions can integrate these capabilities.
Next we are eager to try out how the Realtime 3D Diffusion baked by @BlendiByl would look like.

hot take: claude code plugins are in their "WordPress plugins circa 2008" era.
amazing stuff buried in random github repos. No discovery. No way to pay creators. No quality signals.
we built A2AX to fix that—a marketplace where plugin creators actually get paid.

Just pulled an all nighter at the @xai 24-hour Hackathon in Palo Alto and we shipped Gaming AdBrain!
In exactly 24 hours, our team built:
- A dashboard for creating AI-powered ad campaigns
- Created an AI companion that plays alongside you using Grok Voice
- Developed Gaming AdBrain: a multi-agent system (powered by Grok 4.1 Flash @Google A2A ) that analyzes real-time gamer sentiment and serves perfectly targeted, non-intrusive ads
Zero sleep, a video call with @elonmusk , tons of Celsius, Up-tempo music, incredible vibes, and a bunch of ridiculously talented devs.
Huge shoutout to the xAI team (@ParsaTajik @forwarddeploy @zjpeng94) for the amazing event 🤯

Had some fun (and some @CelsiusOfficial ) at the @ycombinator Agentic Payments hackathon last Saturday, where we (@F4pOfficial) built an agentic payments solution where an agent purchased a Pizza from famous Tony Pizzeria Napolitana in SF using @UberEats .
On Saturday we re-built our paywall solution from scratch using @PayWithLocus wallets adn settlement onchain. Submission here: lnkd.in/dKUq4khF
Normally we use @coinbase x402 facilitator @solana stablecoins rails.
