美国大型电信运营商AT&T称,开放模型目前已经占公司约25%的AI使用量,公司预计未来这一比例可能升至70%—80%。在部分应用场景中,从封闭式专有模型切换到开放模型后,成本已经下降80%—90%。 高盛表示,企业端开始出现很清晰的模型分层:对推理能力要求没有那么极致的任务,可以转向成本更低的开放模型;最复杂的任务则继续使用能力更强的专有模型。随着国产开放模型逐渐成为美国模型的替代选择,高盛跟踪的AI Token成本也已较5月下降49%,模型调用越来越便宜,有利于企业扩大AI使用量,但基础模型厂商的单位价格和利润空间也会面临更大压力。下一阶段AI商业化的竞争,模型能力之外,成本效率的重要性正在快速上升。
