Once made a robot move when I moved my arms (patent, 2019, past life). Now builds AI and 3D stuff for homes. Two daughters, one Dota account, zero free weekends

1/ This is Gurugram. Not a game studio's trailer. One person, open data, and a browser tab. 5 km ร— 5 km of the city, rebuilt in 3D. You can walk it or drive it. ๐Ÿ›บ How it's made ๐Ÿงต

2/ Everything starts from open data: โ€ข Streets and buildings: OpenStreetMap + Overture Maps โ€ข Terrain: Copernicus DEM โ€ข Ground colour: Sentinel-2 satellite imagery โ€ข Building heights: satellite ML estimates No Google or proprietary map data.

Replying to @deepigoyal
@deepigoyal launched dark.ai and a theory of AI agents in the same earnings letter. Agents can reorder your atta. They can't pick your biryani. 65%+ of Zomato opens are people just browsing. Most exposed to agents: District. Concert seats don't need a middleman. Cheat sheet ๐Ÿ‘‡

I turned two weeks of briefing Opus 5.5 on games, 3D, sprites and coded video into one free, interactive field guide. Every line you write shows up on screen. Every line you leave out gets the model's most average guess. What's inside:

1. Describe the finish line, not the route. "AAA" is a mood. "60 fps at 1440p on an M-series laptop" is a spec. Numbers over adjectives, and name the looks you refuse. "Avoid a generic look" just swaps one default for another.

Metaโ€™s Project Phoenix leaks look dope ๐Ÿ‘€ Iโ€™d rather keep my current phone and get this than buy an iPhone Duo just for a bigger screen. Give me a floating cinema, not just a phone that unfolds. @finkd

I asked Astra for an NFS-inspired Delhi racer starring the Mahindra XEV 9e. It built Delhi Afterhours. Nearly 16 km, rain, traffic, drifting and boost. In a browser. Play the prototype: delhi-afterhours-astra.verceโ€ฆ

Astra feels unlike previous models I've used. I can hand it broader work, spanning Blender modelling, city building and game systems. Clear references, room to execute, feedback from the running game. I'm still figuring out how to tame that power.

Ray tracing changed how games simulate light. Neural rendering may change how much they need to simulate at all. I open-sourced an unofficial DLSS 5 video player to explore that shift: github.com/2600th/dlss5-videโ€ฆ Verified on RTX 4080 + 5090.

Made this 30s sci-fi fight with MiniMax H3 running locally on an RTX 5090 + Seedance 2.5. The leap isnโ€™t prettier frames. Itโ€™s control. Production is becoming less of a gatekeeper. Story, taste, direction and the agency to finish are becoming the moat. #AIVideo

Watched Operation Safed Sagar on #Netflix. A few days later, we had this running in a browser. ๐Ÿ‡ฎ๐Ÿ‡ณ A small AI-built 3D experience inspired by the courage, ingenuity and flying missions of the Kargil War. Hereโ€™s what we made ๐Ÿ‘‡

You fly a MiG-21 through the snowy Kargil mountains on a reconnaissance mission, navigating the terrain and photographing enemy positions. No install. No game engine download. Just open the browser and fly. โœˆ๏ธ

Update: some of you managed to crash my AI-built ocean ๐Ÿ˜„ So I went back in. It now loads faster, uses far less memory, and should work on many more devices. If it failed before, give it another shot ๐Ÿ‘‡ web-ocean-3d.vercel.app/ #GameDev #VibeCoding #ThreeJS

I wanted to test a simple question: How far can we push todayโ€™s AI models on a real-time 3D experience? So I gave Opus + Sol a target: build toward a Black Flag-inspired ocean + ship experience, running entirely in the browser. ๐ŸŽฎ web-ocean-3d.vercel.app/ teapawt.net/2600th/status/20857884โ€ฆ

The experiment was inspired by @mattshumer_ and his work around pushing AI coding agents harder. The shift for me: stop treating the model like a one-shot code generator. Build โ†’ run โ†’ inspect โ†’ critique โ†’ fix โ†’ repeat. Each loop raises the bar a little more.

ARC-AGI is one of the hardest AI benchmarks. It tests pure abstract reasoning, not memorization. Human baseline is around 95.4%. Prime Intellectโ€™s new open-source Prime Agent just scored 95.5% on ARC-AGI-3 with no special training. Pretty wild. github.com/PrimeIntellect-aiโ€ฆ

Most AI demos show what the model can do. Terry Taoโ€™s Jacobian Conjecture session shows what expert judgment adds: better questions, sharper rejection, and verification. chatgpt.com/share/6a5fdc7a-dโ€ฆ #AIEngineering #AIAgents

Was using claude fable and burnt through the Max 20x limit in under 30 min. RCA: fable spins up fable sub-agents for various tasks. Fix: Add this to you CLAUDE.md:

"Before spawning a subagent, choose the correct model tier for its task to optimize cost: use a small/fast model (e.g. Haiku-class) for search, summarization, and mechanical work; a mid-tier model (e.g. Sonnet-class) for routine implementation; and reserve the strongest model for complex reasoning, architecture, or debugging. Use the agent type's recommended default when one exists; do not pass the most expensive model by default."

Plot twist: the AI safety lab is now powered by Elon's rockets. He always wins in the end. @elonmusk
Weโ€™ve agreed to a partnership with @SpaceX that will substantially increase our compute capacity. This, along with our other recent compute deals, means that weโ€™ve been able to increase our usage limits for Claude Code and the Claude API.
