By any chance did you tried Deepseek 4 or 4.1 and GLM 5.3 or flash?

I've done GLM 5.3 previously here: https://news.ycombinator.com/item?id=49295420

Worth noting though that GLM 5.3 isn't multi-modal, so it doesn't have a vision layer. It is quite clever and hacks around it pretty effectively however. I'm running a deepseek 4 build now and will reply shortly with that.

Awesome. You have a really neat benchmark.

glm5.3-flash is multimodal and I\ve been testing it against opus over the last ~10 days and it does very well at a fraction of the opus price...

I should give it a spin. 5.3 wasn't multimodal, but it looks like their flash release was. Thanks for the tip.

Deepseek 4.1 is also multimodal BTW
