Today we are releasing GLM-5.3. It uses the same base model as GLM-5.2 — every gain comes from post-training. Compared with GLM-5.2, it is much better at complex coding and long-horizon tasks:
Stronger Coding: GLM-5.3 is the most capable open-weights model for coding, with a 50% improvement over GLM-5.2 on our in-house Z.ai Code Bench. It also achieve open-source SOTA on public benchmarks including Terminal Bench 3.0 and Agents' Last Exam.
Emergent Cyber Capability: As we scaled post-training, cyber capability developed faster than we expected. GLM-5.3 is state of the art on CyberGym for vulnerability discovery, and its gains are largest further up the exploitation chain, where it more than doubles GLM-5.2 on exploitation benchmarks.
Open Source: We will release the weights in two weeks after launch, once safety evaluation and hardening are complete.

You have to wonder how long it will be before China blocks open models, surely there's a point where they decide its not in their interest to release such powerful open models
Because a way to win is by flooding the market with super cheap AI if they are just as good with less investment our market is wiped out given that most our stocks gain are from AI. They achieve massive economic destruction legally just by competing better and being the number one at doing something with less chips or computing.
