Gemini 2.5 Pro vs. Claude 3.7 Sonnet: Coding Comparison

Here is a real coding problem that I might be willing to make a cash-prize contest for. We'd need to nail down some rules. I'd be shocked if any LLM can do this:

https://github.com/solvespace/solvespace/issues/1414

Make a GTK 4 version of Solvespace. We have a single C++ file for each platform - Windows, Mac, and Linux-GTK3. There is also a QT version on an unmerged branch for reference. The GTK3 file is under 2KLOC. You do not need to create a new version, just rewrite the GTK3 Linux version to GTK4. You may either ask it to port what's there or create the new one from scratch.

If you want to do this for free to prove how great the AI is, please document the entire session. Heck make a YouTube video of it. The final test is weather I accept the PR or not - and I WANT this ticket done.

I'm not going to hold my breath.

What’s the point of a one-to-one GTK3 → GTK4 rewrite when the user experience doesn’t improve at all?

Why not modularize the backend and build a better UI with tech that’s actually relevant in 2025?

> Why not modularize the backend and build a better UI with tech that’s actually relevant in 2025?

Doing the second part is to my understanding actually the purpose of the stated task.

Why are you calling GTK4 irrelevant? Large swaths of Linux run on it and GTK3

> Why are you calling GTK4 irrelevant?

Quite the opposite: Gtk4 is relevant, and porting Solvespace to this relevant toolkit is the central part of the stated task.
