Scaling post-training is all we did for GLM-5.3.

What a way to start

Gentlemen, gentlewomen, tonight, WE FEAST!

Of course it’s only posttrain.

I would be shocked if GLM pretrained a completely new model for a +0.1 release. Nobody really does that (with the exception of Anthropic and Opus 4.7 for some weird reason).

Gpt 5.5 was a new pretrain, i think got 5.2 also might be coz it was so different from previous versions

That’s a +0.5 version though, and there’s a lot of 0.5s that’s a new pretrain. Qwen 3.5, for example.
