Editor’s verdict

Azure OpenAI brings GPT models into the Azure ecosystem with enterprise compliance, private networking, and unified billing; AWS Bedrock offers a model-agnostic platform (Claude, Llama, Mistral, Titan) with deep AWS integration. Choose Azure OpenAI if your stack is Microsoft-centric; choose Bedrock for multi-model flexibility within AWS.
