百度推出 Token Exchange 模型市场，用模型指纹与供应商信用评级把关
Baidu Launches Token Exchange, a Model Marketplace That Fingerprints Models and Rates Suppliers
百度把模型采购做成了交易所：指纹验证防供应商偷换模型，还有准入测试和信用评级。每天 7000 亿 tokens 的盘子，说明企业采购模型 API 的玩法正在变。做多模型接入或企业采购的团队可以看看这套机制怎么设计。
百度发布 Token Exchange，一个将多家供应商模型整合在同一 API 之后的模型交易市场，官方称目前每天服务 7000 亿 tokens 的调用量。
平台的核心机制有三层：首先通过模型指纹（fingerprint）技术核验供应商实际交付的模型是否与宣称一致，防止偷换模型或冒充更强模型；其次设置准入测试，模型上线前需通过质量验证；最后为每个供应商建立信用评级体系，供采购方参考。
这类撮合模式让应用方不必逐家对接模型厂商，也不必自行验证模型真伪，托管、质检和信用评估都由平台完成。相比直接从单一厂商采购 API，企业可以在一个入口内比价和切换供应商，这对需要多模型混部、成本敏感的中大型企业尤其有参考意义。
