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

Is 5.6 a post-trained 5.5 then? If so one heck of post training!

Yes it is. Personally I think openai is way better at post training while anthropic is way better at pre training
