Best models for AI agents, ranked

GLM-5.3 ranks for automation-shaped, long-horizon tasks: reliable function calling, structured output, and lower cost per step than closed-frontier alternatives.

Ranked by a stated method

Ranking combines the Artificial Analysis Intelligence Index, task-specific evaluation results where independently reproduced, and price per million tokens. Vendor-only claims are excluded from the ranking itself and shown separately where relevant.

This is not a universal winner

A ranked list compresses many workloads into one order. Check the linked comparison for your specific workload before deciding — especially where modality support or self-host requirements are the deciding factor.

Frequently asked questions

Where is the live GLM-5.3 model page?

The canonical model page with current OneInfer pricing, capabilities, and availability is /models/zai-org/GLM-5.3. This page is a focused facet of that entity, not a replacement for it.

How should I treat benchmark or price claims?

Check each claim’s provenance label and observed date. Vendor-reported and independently verified numbers are shown as separate evidence classes on this hub.
