Open sourcing the San Francisco playground! It's now multiplayer with a map you can use to teleport all around, and you can switch between walking, driving, boating, and flying a drone, plane, or phoenix (using mouse/keyboard or controller) . When you get close to others you can talk with them using webrtc. No account signup needed, just enter a name and start exploring. You can also share a link from anywhere in the city with a friend and they'll hop in right next to you Fable did a great job finding all the open source data on SF, using that to create the buildings, roads, etc in blender, and building the pipeline to chunk it up and optimize it for streaming in threejs. For specific landmarks that I wanted to look nicer then the low poly automated structures, I gave claude screenshots of and asked it to create a higher quality version of the structure . Currently adding in some interactive exhibits like a fluid sim and an immersive music dome into the exploratorium. Links below (app includes a writeup which goes into much more depth on the process and systems involved)

how good is GPT 5.6 Sol Ultra at complex road topology? I gave it 100 test cases to produce and verify, here are the results after the first pass So far it appears to be improved in its vision capabilities compared to 5.5, however it still seems to make the same mistake as Fable by doubling down on wrong assumptions (looking for an easy verifiable fact on a road screenshot case and completely ignoring a huge hole it should've seen) AGI has not been achieved i'm afraid Banger model tho, ngl, we'll see what it looks like after a couple more iterations.
