Z.ai: GLM 5
Analysis Summary
Z.ai’s GLM 5 is a text model with tool use, function calling, and a 204.8K context window. Its intelligence index is 27.9, but the supplied record includes no coding or agentic benchmark results. That makes it difficult to judge how well it handles software tasks or whether its tool use remains reliable across longer sequences.
The context window and listed input and output prices of 0.6 and 1.92 make it a candidate for testing on document analysis and text workflows. For production use, verify instruction following and factual consistency on the kinds of material clients actually provide. Keep tool permissions narrow until the model’s behavior is established.
GLM 5 may suit teams seeking a relatively low-cost, long-context model with tool integration. It is better positioned as a secondary option under evaluation than as the default for complex or high-stakes work.
