The models' case: Best overall blend for a typical global HTTP API: extensive edge reach, programmable caching with Workers, tiered caching, smart origin routing, load balancing, and. The models' main caveat: Many decisive routing and API-security features cost extra, while Worker Cache API data remains POP-local, making advanced caching less intuitive. The strongest alternative is Fastly — Built for dynamic/API traffic rather than static cache hits—Instant Purge (~150ms global), origin shield, VCL + Compute (Wasm) with sub-ms cold starts. Not unanimous: Grok picks Fastly.
