GLM-5.2 price jump shows why AI agent costs need monitoring
price checks every few hours showed a sharp rise in GLM-5.2 costs this week. Input rose from about $0.57 to $0.90 per 1 million tokens, and output rose from about $1.80 to $3.08 per 1 million tokens. The change happened through about 10 separate price adjustments over 7 days, with no public or announcement.
Tencent’s new Hy3 model also moved around, first dropping and then rising. Low-cost Chinese models can still be much cheaper, as Nex-N2-Mini launched this week at $0.025 for input and $0.10 for output per 1 million tokens. The practical lesson is to avoid locking an AI agent to one provider just because it is cheap today.
If a model is chosen mainly for price, that price should be watched continuously.
