2026年生成式AI与LLM云成本优化实战指南:GPU实例、推理成本与Token经济学全攻略
生成式AI在2026年已成为企业云账单上膨胀最快的支出项。本文从GPU实例选型、推理优化、Token经济学到向量数据库成本,给出AWS/Azure/GCP三大平台可立即落地的省钱方案,并附完整代码示例与FinOps监控策略,帮你在30天内把LLM账单砍掉40%-65%。
Hannah was a senior FinOps analyst at Spotify for four years, where she sat between the platform engineering org and the CFO's office, owning the showback model for 600+ engineering teams. She built the internal tool that broke down per-squad spend by Kafka topic, which the company still uses. Before Spotify she worked at Klarna on payments infrastructure cost, and started her career as a data engineer at Ericsson. She holds the FinOps Certified Professional credential and AWS Solutions Architect Associate. Her writing leans heavily on the FinOps Foundation framework - inform, optimize, operate - and she has strong opinions about why reserved-instance utilization reports lie to you if you read them naively. Hannah lives in Stockholm, writes mostly about multi-cloud chargeback, anomaly detection on daily spend, and the politics of getting engineers to care about a number that isn't latency. Eleven years total in the industry.
