Z.ai: GLM 5.3 Prime
🇨🇳 Z.ai (Zhipu) · GLM 5.3
Overview
Z.ai: GLM 5.3 Prime is a large language model API from Z.ai (Zhipu), part of its GLM 5.3 model family. Priced at $2.80 per million input tokens and $8.80 per million output tokens, it occupies the mid-range, balancing capability against running cost. Output tokens cost about 3× as much as input, so prompt-heavy workloads run noticeably cheaper than generation-heavy ones. An exceptionally large 1M-token context window (≈1,500 pages of text) means entire repositories or document collections can be processed without chunking. All prices on this page reflect OpenRouter's routed rates and are re-synced automatically every day; confirm against the provider's official pricing before committing to production.
