Watch for

Priced from OpenRouter's routed market, not a first-party list price — availability and rate can shift without notice.
Text-only — no image, audio, or file input.

These notes are derived from price, context and modality — structural facts, not measured quality. Measured cost-to-finish-a-task lives on the real-cost index.

How to read GLM 4.6's pricing

Two numbers decide most of the bill: $0.43/1M for input (everything you send — prompt, context, attachments) and $1.75/1M for output (everything it generates, including hidden reasoning tokens). Output is priced 4.1× the input rate here, so the shape of your workload — how much it reads versus writes — matters as much as the headline figure. This row is OpenRouter's routed market price; it can move as providers and routing change.
