$1.40 in / $4.40 out per 1M tokens — official pricing
In plain English: MIT-licensed weights on Hugging Face and ModelScope. Cached-input price is $0.26/1M, far below the $1.40 shown. GLM-5.3 (2026-08-14) is positioned by Z.ai as the successor in this line, but is subscription-only with 'API coming soon' — GLM-5.2 remains the purchasable API model, so we keep it current until GLM-5.3 is actually available via API.
