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 Jul 16, 2026, 8:19 AM UTC. Values use one deterministic route per provider and model; missing measurements remain visible as N/a.

Azure vs OpenAI analysis

How Azure and OpenAI compare for AI inference

Azure and OpenAI share 33 indexed text models, including GPT-5.6 Luna Pro, GPT-5.6 Luna, GPT-5.6 Terra Pro, GPT-5.6 Terra, GPT-5.6 Sol Pro. OpenAI has the stronger typical response-time result on the directly measured set.

Same-model speed evidence

29 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.

Token pricing on one workload

33 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.

Catalog and deployment differences

Azure has 50 indexed models and lists 2 published server regions; OpenAI has 72 models and lists no regions. Verify data residency, privacy terms, limits, and production latency directly before choosing.
