A cloud provider counts only where its entry names its model service (Azure OpenAI, Amazon Bedrock, Vertex AI or Gemini), not when it is listed for hosting. Apps with AI features and tools around models (vector databases, tracing) are not counted.

"Since" dates are when we first read the list with the provider on it; "added" dates are when a later reading found it added. A vendor missing here may still use a provider its list doesn't name, or one reached through another company; many list a provider for an optional feature. Each date links to the copy of the list it was read from.
