AI 摘要

Z.ai 于 6 月 13 日发布 GLM-5.2，这是 GLM-5 系列四个月内的第四款旗舰编码模型。核心亮点是可用的 100 万 token 上下文窗口（标识为 glm-5.2[1m]），每轮最多输出 131,072 token，约为 GLM-5.1 的 5 倍。新增 High 和 Max 两种思考强度级别，Max 推荐用于复杂多步编码任务。架构未在发布时公开，但社区指出 GLM-5 基础为 744B 参数的 MoE 模型，每 token 激活 40B 参数。Z.ai 未公布任何基准测试分数。GLM-5.2 兼容 Claude Code、Cline 等 8 种编码智能体工具，可通过 Anthropic 兼容端点直接替换使用，对所有 GLM Coding Plan 用户（Lite/Pro/Max/Team）开放。

GLM-5.2 is the latest large language model from Z.ai, becoming the third major release in the GLM-5 line. It follows GLM-5 (February 11), GLM-5-Turbo (March 15), and GLM-5.1 (April 7). That makes four flagship-tier coding releases in roughly four months.

Usable 1M-Token Context Window

GLM-5.2’s standout spec is a 1,000,000-token context window. Z.ai labels the variant glm-5.2[1m] in its own configuration. Each response can return up to 131,072 output tokens. That is roughly a 5x jump from GLM-5.1’s 200,000-token window.

A 1M-token window changes how a coding agent works in practice. The agent can hold an entire mid-sized repository in working memory. That includes source files, tests, configuration, and conversation history. It avoids the constant summarization that smaller windows force.

The release also adds two thinking-effort levels: High and Max. Z.ai recommends Max effort for complex, multi-step coding work. In Claude Code, the /effort command controls this setting. The xhigh, max, and ultracode options all map to GLM-5.2’s Max effort.

Architecture and What Changed

Z.ai did not specify GLM-5.2’s architecture in its launch materials. But based on community notes, the GLM-5 base is a 744-billion-parameter Mixture-of-Experts model. It activates 40 billion parameters per token. GLM-5.1 kept that same backbone with retargeted post-training.
