Microsoft and Amazon 'Undermining Each Other's Foundations': Claude Lands on Azure, OpenAI Enters Bedrock

According to monitoring by Beating, the exclusive cloud alliances of the two major AI model camps have officially disbanded. Anthropic announced that its Claude 4.x series (including Claude Opus 4.8 and Claude Haiku 4.5) is now officially available on Microsoft Azure AI Foundry, running directly on NVIDIA GB300 GPU computing power. Correspondingly, OpenAI's GPT-5.5 and GPT-5.4 were launched on Amazon AWS Bedrock two months ago. Cloud giants are retreating from 'exclusive models' to becoming 'gateways for computing power and traffic,' while large models are moving toward a multi-cloud distribution utility phase.
