Vespa Ai Rate Limits

Vespa serving throughput is governed by application configuration (per-container HTTP threads, document API concurrency, query timeout) rather than a fixed per-key request quota. The values below reflect Vespa's default protection mechanisms and Vespa Cloud guidance.

Vespa Ai Rate Limits is the machine-readable rate-limit profile for Vespa on the APIs.io network, conforming to the API Commons Rate Limits specification.

It captures 6 rate-limit definitions, measuring queries_per_second, writes_per_second, concurrent, seconds, and documents.

The profile also includes response codes documented for throttled, serverError, and timeout.

Tagged areas include Rate Limiting, AI Search, and Vector Database.
