GPT on AWS: 24 Hours After Microsoft Lost Its Lock

=== SHORT_SCRIPT ===
Microsoft held EXCLUSIVE cloud rights to every OpenAI model for SEVEN YEARS. GPT-5.4 went live on Bedrock within 24 hours of that ending.

OpenAI had a $100 billion AWS cloud deal ready and waiting. Three products launched on Bedrock simultaneously: frontier models, the Codex coding agent, and Bedrock Managed Agents built jointly with Amazon. GPT-5.5 arrives on Bedrock within weeks. The pricing matches the direct OpenAI API exactly. Five dollars per million input tokens. Thirty dollars per million output tokens. Zero Bedrock surcharge. No platform tax. OpenAI's own revenue chief told employees the Microsoft exclusivity had been blocking them from the enterprise customers they most needed to reach. The deal ending was not a loss for OpenAI. It was the opening they had been building toward for months.

Now OpenAI is spending $100 billion with AWS and $250 billion with Azure while keeping the customer relationship entirely for itself. Microsoft traded a monopoly for a 27 percent equity stake. Anthropic loses its first-mover advantage on Bedrock. Google is already asking what comes next. The cloud is the commodity now. The model is the product. Stay sharp.
