智谱 AI 发布新基础模型 GLM-5.3 的 API，聚焦复杂编码、网络安全防御和长程任务，在 Artificial Analysis Intelligence Index 得分 60，进入全球前沿模型梯队。该模型已接入 ZCode 和 GLM Coding Plan，与 Kimi K3 并列为领先开源模型，权重定于下周开源。
原文交代了 GLM-5.3 的能力侧重、基准分数和开放节奏，读者可以据此判断其在开源与闭源模型中的位置。
Zhipu AI has launched the API for its new foundation model GLM-5.3. The model focuses on complex coding, cybersecurity defense and long-horizon tasks, scoring 60 on the Artificial Analysis Intelligence Index and entering the global frontier model tier.
GLM-5.3 is positioned alongside closed models such as Anthropic’s Claude Fable 5 and OpenAI’s GPT-5.6 Sol, while tying with Moonshot AI’s Kimi K3 as a leading open-source model. It is already integrated into Zhipu’s ZCode and GLM Coding Plan, with model weights scheduled to open-source next week.
