A per-model winner combines blended price and estimated 500-token response time with equal proportional weight. Ties and rows missing either measurement receive no badge. Comparison data calculated . Values use one deterministic route per provider and model; missing measurements remain visible as N/a.
Google Vertex vs SiliconFlow analysis
Google Vertex and SiliconFlow share 5 indexed text models, including Gemma 4 26B A4B, DeepSeek V3.2, DeepSeek V3.1, gpt-oss-120b, gpt-oss-20b. Google Vertex has the stronger typical response-time result on the directly measured set.
3 shared models currently have complete response-start and output-speed measurements on both providers. The speed comparison uses per-model ratios before taking the median, so naturally faster model catalogs do not improve the result.
5 shared models have complete input and output prices on both providers. Prices use the same 1,000-input/500-output-token mix and are normalized to one million tokens for readability.
Google Vertex has 49 indexed models and lists 7 published server regions; SiliconFlow has 36 models and lists 1 region. Verify data residency, privacy terms, limits, and production latency directly before choosing.
