GLM-4.5 AirX (Z AI)

GLM-4.5 AirX is attributed to Z AI as an open-source language model within the broader GLM family, positioned as a text-only offering for general-purpose generation and reasoning workloads. The model is presented through third-party pricing aggregators rather than official Z AI documentation, so its technical lineage and intended deployment scenarios remain loosely defined. Based on available listings, it carries a 131.1K token context window, aligning it with the larger-context tiers of recent GLM variants suitable for extended document processing and multi-turn conversations.

In practical terms, GLM-4.5 AirX is priced at $1.10 per million input tokens and $4.50 per million output tokens, giving it a blended rate that places it in a mid-range cost band compared to competing open and proprietary alternatives. The lack of independently verifiable benchmark scores, architectural disclosures, or parameter counts for this specific AirX variant means buyers should rely on direct evaluation rather than published performance claims. Its combination of open-source licensing and a sizable context window makes it a reasonable candidate for developers seeking flexible deployment without proprietary lock-in, though organizations should verify capabilities such as tool calling and temperature control against their own use cases.
