Z.ai launches GLM-4.5 to supercharge coding and AI agents
Z.ai just introduced its new flagship MoE models, GLM-4.5 and GLM-4.5-Air, prioritizing depth over width to enhance reasoning and autonomous agent capabilities. GLM-4.5 features 355B total parameters with only 32B active, launching with day-one support on SGLang alongside FP8 variants. Why it matters: it hits a 90.6% tool-calling success rate and outpaces Claude 4 Opus on web browsing, making it a formidable foundation for autonomous workflows.
