GLM-4.5-Air is the lightweight variant of Z.ai's latest flagship model family, also purpose-built for agent-centric applications. Like GLM-4.5, it adopts the Mixture-of-Experts (MoE) architecture but with a more compact parameter size. GLM-4.5-Air also supports hybrid inference modes, offering a thinking mode for advanced reasoning and tool use, and a non-thinking mode for real-time interaction.
