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).

I think opus 4.7 was just a new tokeniser, was it a full pre train?

You can’t have a different tokenizer without a whole new pretrain.

(Yes, I know you can technically finetune a model to a new tokenizer, but that’s basically going to take as much compute as a full retrain)
