The B in a name like gpt-oss-20b counts parameters, in billions. Multiply that count by the bytes each parameter takes and you get a floor for the memory the weights need. That is also why some models now ship with two numbers instead of one.
GLM 5.2 shipped with open weights under an MIT license, which generally permits third parties to host and commercialize inference. As of writing, OpenRouter lists twenty-five providers offering it, at input prices from $0.93 to $3.00 per million tokens.
據 CNBC 報導，美國公司經 OpenRouter 用在中國 AI 模型上的 token 佔比，從前十二個月平均 11% 升到 2 月 8 日以來每週 30% 以上、最高 46%。受訪者明確指出價格正在推動任務分流；六月的模型下架與解禁，也讓取用穩定性成為要一起看的風險。
