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.

My coding challenges are all variations on "start with this 1.5M line Spring project, full of multi-thousand-line files..."

But you are aware that their limited context length just won't be able to deal with this?

That's like saying that you're judging a sedan by its capability of performing the job of a truck.

Wait, you were being sarcastic?
