## AI 摘要

智谱发布 GLM-5.3，与上一代 GLM-5.2 共享相同基座，全部提升来自扩展的后训练，并称其为最强开源权重编程模型，智能体任务进步最大。该模型经安全数据训练，在 269 个项目中找到 2,436 个漏洞，部分漏洞存在长达 40 年。GLM-5.3 现可通过 GLM Coding Plan 使用，权重将在安全审查完成后于两周内开源。

Chinese AI startup Zhipu AI has released GLM-5.3. The model shares the same base as its predecessor, GLM-5.2, and all gains come from extended post-training alone. Zhipu says GLM-5.3 is the most powerful open-weights coding model, with the biggest jumps in agent-based tasks.

One area where top Chinese models like Kimi or Qwen still lag behind US frontier models is cybersecurity. Zhipu trained GLM-5.3 with data and environments built to find software vulnerabilities. According to Z.ai, the model "began to reason across multiple stages of exploitation, forming coherent plans for complete exploitation chains." Working with security teams in China, the company says it found 2,436 vulnerabilities across 269 projects, some up to 40 years old. The flaws are documented in a public registry.

GLM-5.3 is available now through the GLM Coding Plan and works with coding agents like ZCode, Claude Code, or OpenCode. The model weights are set to go open source in two weeks, once security reviews wrap up.
