I asked it for it's harness and then asked agy to do a teardown. It's a monolithic 332MB binary written in Rust from scratch.

Full teardown is here:

Nicely done. I asked Muse for the Hatch binary the day it launched (I actually left a comment about it - literally the last one I made on HN), but I just scanned the strings of it to get a general idea of what it did and left it at that. It didn't dawn in me to ask Antigravity to analyze it.

This teardown answers pretty much all the questions I had after I looked at it. Great job.

That's somewhat surprising to me. Is there any reason they'd run the harness on the VM itself, rather than in a different sandbox with root shell access to the VM as a tool call?

Maybe they just don't consider it to be their moat/secret sauce.

Antigravity is such a dumb name. An-ti-gra-vi-ty (5) is long, Ge-mi-ni (3) was better.

Aren’t Marketing/PR people at FAANG supposed to be among the best in the industry?

They actually paid [1] Lexicon Branding for this dumb ass name (probably millions of dollars).

Bard is still the best

Zune would like a word

Just as ChatGPT is now called "Chat" by the kids (go ahead and finish grinding your teeth, I'll wait...), if Antigravity takes off then it'll get an irksome nickname like Antigrav or just Grav.

the kids don't call it that. only grown men in the bay area call it that.

The kids and adults. That's what my mom calls it.

how about gravy? or aunti-gravy?

just call it google grav

Where it will end up anyway.

remember "kubernetes" ?

You mean kaids?

oh dear
