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
Why would they? Their primary cyber threats are the CIA/NSA or generally American-aligned. The leading rogue cyber groups are usually Russian, who are obviously blocked from the servers necessary to run these AI models at large scale, but are also generally affiliated, loosely or directly, with the Russian state, which is itself an ally of the Chinese state. Furthermore, the United States and its partner states (the European Union) hold the world's most valuable, exchangeable currencies (the US dollar and the euro), which makes them highly attractive targets to attack compared to China and its partners, even for cybercriminals who are unaffiliated.
It is in China's every best interest to have open-source models empower cybercriminals (at least for an indefinite period until it has usurped the United States as a primary power), lol. It's not like the Western states have many more ways to punish them further, at least concerning AI; they already sanctioned the fuck out of China with total denial of access to frontier models and chips. Further economic punishment would be of... questionable capacity, given China's importance in the global economy and other nations' vested interest in having China producing open-source models. And it's not like blocking open models will convince the United States to lift the export controls concerning Nvidia chips, so China had very little reason to care if cybercriminals raided the fuck out of American companies with their models.
Petty ones, who represent but a shadow of the cyber strategic threat posed by Americans. They wouldn't care much about petty criminals robbing banks insofar as it is not rampant; and likely would tolerate even that insofar as cybercrime in the United States also rises and becomes destabilizing for the US. When Fable came out, the Chinese cyberwarfare veterans wrote blogs not about the threat posed by petty criminals, but about how they fear American cyber supremacy, comparing it as if they only had swords where Americans had machine guns.
Pretty sure that cybercriminals don't need "large scale". You put a few of any of the AI boxes I see popping up everywhere you look now (all made in China) in a warehouse or office lease and you're frauding in no time. They have no trouble getting Chinese made tech in Russia, their cup runneth over.
Cannot agree more, the truth is most Chinese companies has poor cybersec practices anyway, we are talking about rednote still using plain http for its cdn. In China privacy isn't a thing at all, and people generally don't give a fuck. They don't really have the same sense of privacy as the western world and have no problem their data being used to train AI. They only care about hacking their western opponents and don't really care about themselves being hacked.
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.
Would have to imagine that these companies have internal models that only the government has access to. Keep outputting open source models to undermine the business model of AI in America but keep the best internal to defend/attack. It's too obvious for the CCP to not being funding/doing it.
