AWS S3 Vectors
storage at six cents a gigabyte, and it reprices the floor of the market
roughly five times cheaper per gigabyte than the premium managed options, and explicitly built for cost rather than latency — choose it deliberately, not by default.
general availability arrived in december 2025 with two billion vectors per index, and it reached thirty-one regions by march 2026. storage is six cents per gigabyte per month, queries are priced per million with a tiered data-processing charge that falls as your index grows, and the first half-megabyte returned per query is free.
against premium managed vector databases charging around thirty-three cents a gigabyte, that is a structural change rather than a discount, and aws has been pointed about calling it complementary to dedicated vector databases rather than a replacement.
the description above is ours, condensed from the ranking. pricing moves — check it on the vendor's own page before you rely on it.

we researched this category against vendors' own pricing pages and licence files. that is where this line comes from — not from the vendor, and not from anything they paid for.
