So I've made this [me+vibe+tests]-coded Android alarm app called Promptly, and as Gemini-CLI on the Google Pro subscription is getting google-killed on June 18th, I set up two branches, one for Antigravity+Gemini3.5 and one for Pi-coding-agent with Qwen3-Coder-Next...

Running the same prompt on both with the same .md memory state...

Gemini3.5 is more "intelligent" but Antigravity gets it to decide to go on tangents that are quite time and token-consuming I think. Nice casino machine.

Pi+Qwen3 (~80GB, llama.cpp) is like vibecoding about 1.5 years ago, when you had to babysit, structure your program to have self-contained chunks, and keep an eye on all the cross-cutting concerns to not trip it up. When it works it works fine and when it fails it's my job to ensure it fails fast.

The code is about 10'000 lines of Kotlin in total so it already takes some effort to keep it simple for the AI. It's not a slopped quantity of code, i got solid feature creep :^)
