Zhipu AI (Z.ai)

GLM-5.3

Pricing

— in / — out per 1M tokens

In plain English: No per-token API pricing yet — access is via GLM Coding Plan subscription ($18/$72/$160 per month) and ZCode, API 'coming soon'. Same 743B base model as GLM-5.2; all gains from scaled post-training (Z.ai claims +50% coding). Z.ai's own runs report DeepSWE v1.1 66.9 and Agents' Last Exam 28.5, but both used vendor harnesses that are not comparable to the independent leaderboards we track, so they are not listed as scores. Weights release delayed for safety evals after emergent exploit-chain capabilities.
