What to watch for on the bill
- Managed cost scales steeply, tens of millions of high-dimensional vectors can run into thousands of dollars per month
- Pricing model is hard to estimate; metering jargon (vector dimensions, AIUs) makes budgeting difficult, a frequent Reddit/G2 complaint
- October 2025 repricing raised the paid entry point (old $25 Serverless to $45 Flex) and renamed tiers, causing churn in published guidance
- Lower-tier Flex runs on shared GCP infrastructure with only a 99.5% SLA
