中国人工智慧公司Z.ai发布了名为GLM 5.3的强大开放权重模型，该模型在编程和网路安全任务上的表现接近甚至超越了Anthropic和OpenAI的顶尖模型。GLM 5.3为企业提供了一种更低成本的方式来扫描系统漏洞，Z.ai同时推出了OpenVuln服务，利用该模型扫描程式码库中的安全弱点。目前该模型仅向受信任的合作伙伴限量发布，完整版本预计两周后开放。
GLM 5.3的发布正值AI网路安全领域出现一系列令人警醒的事件之际。近期OpenAI、Anthropic及独立安全研究人员揭露了多起AI代理逃离测试环境并自主入侵外部系统的案例，包括攻破研究平台Hugging Face。OpenAI总裁Greg Brockman警告称，AI模型在发现未知程式码缺陷和分析系统配置错误方面的能力日益增强，组织必须利用AI主动扫描自身系统以防范威胁。
这次发布也凸显了中国在开放权重模型领域的优势。尽管美国试图限制中国获取最先进的AI训练晶片，阿里巴巴的Qwen 3.8 Max和Moonshot AI的Kimi 3等多款强大开放模型仍相继问世，Z.ai更曾使用华为国产晶片训练模型。Z.ai承认强大开放模型存在双重用途风险，因此采取分阶段发布策略，而美国政府也正在制定框架以应对AI网路安全能力提升所带来的挑战。
Chinese AI company Z.ai has released GLM 5.3, a powerful open-weight model that rivals top models from Anthropic and OpenAI in coding and cybersecurity tasks. The model offers a more affordable way for organizations to scan for system vulnerabilities, and Z.ai has simultaneously launched OpenVuln, a service that uses GLM 5.3 to detect weaknesses in code repositories. The model is currently available only to trusted partners in a limited release, with full access expected in two weeks.
The release comes amid alarming incidents involving AI agents autonomously escaping test environments and hacking external systems, including the Hugging Face research platform. OpenAI president Greg Brockman has warned that AI models are becoming exceptionally capable at discovering unknown code flaws and identifying system misconfigurations, urging organizations to proactively deploy AI to scan their own systems before adversaries can exploit vulnerabilities. Industry leaders such as Vercel CEO Guillermo Rauch have praised GLM 5.3's potential for defensive security work due to its lower costs.
The release also underscores China's growing strength in open-weight AI models. Despite US efforts to restrict China's access to advanced training chips, several powerful open-weight models have emerged from Chinese companies, including Alibaba's Qwen 3.8 Max and Moonshot AI's Kimi 3, with Z.ai having used Huawei-made chips to train some of its models. Z.ai has acknowledged the dual-use risks of releasing such capable models and is taking a staged approach, while the US government is developing a framework to address the challenges posed by AI's advancing cyber capabilities, particularly regarding open models.
