## About z-ai/glm-5.2

GLM-5.2 is Z.AI's text model for long-horizon coding and engineering, with 1M context, 128K output, and configurable reasoning effort.

### Best for

Project-scale code review, refactoring and migration, long-document analysis, and engineering agents using MCP or functions.

### Core strengths

- A 1M context window fits complete repositories and large engineering evidence sets.
- reasoning_effort tunes depth for complex tasks.
- Supports functions, streaming tool calls, structured output, caching, and MCP.

### Limitations

- It is text-focused; images, video, and GUI understanding need a vision model.
- Very long input and 128K output require max_tokens limits and caching.

### Selection and production evaluation

Start a z-ai/glm-5.2 evaluation by mapping its official positioning to real work: Project-scale code review, refactoring and migration, long-document analysis, and engineering agents using MCP or functions. The first pass should exercise both its main strength, "A 1M context window fits complete repositories and large engineering evidence sets.", and its known limitation, "It is text-focused; images, video, and GUI understanding need a vision model.", instead of relying on a single subjective general-chat comparison.

For access, MoleAPI currently lists openai protocols and the Standard billing groups for this Zhipu model; the default price summary is Input $0.87 / 1M tokens · Output $3.48 / 1M tokens. Pricing, protocols, and groups come from the live catalog, so production planning should still price representative requests using real context length, output size, and cache-hit assumptions.

No independent ranking is shown unless it matches this exact model ID and reasoning profile, so nearby variants are not used as a proxy. Before launch, pin the model ID, prompt, and sample set, then compare task accuracy, structured-output validity, tool-call success, and timeout rates under the same conditions.
