Architectural Profile & Capabilities

GLM-5.1 delivers dependable intelligence for coding, drafting, summarization, and interactive reasoning on the ECO tier.

Architecture Type: Mixture of Experts (MoE)

Sparse Mixture-of-Experts routing: activates only a subset of parameter experts per token, delivering frontier-level intelligence with exceptional efficiency.

Recommended Workloads & Primary Use Cases

General-purpose reasoning

Technical drafting

Code assistance

Fast iteration

ARMES Zero Data Retention

Calls to GLM-5.1 are routed through strict Zero Data Retention inference channels. Prompts and outputs are never stored, indexed, or monitored by Z.ai.
