AWS just turned OpenAI’s post-Microsoft freedom into a Bedrock sales pitch
AWS just gave large companies a new way to buy OpenAI without going through Microsoft's Azure cloud. One day after OpenAI said its revised Microsoft deal now lets it serve products across any cloud provider, Amazon Web Services said GPT-5.5 and GPT-5.4 will be available in preview on Bedrock, AWS's managed AI platform for buying and governing models.
That matters because this was not just a model-listing update. OpenAI said the same partnership also brings Codex, its coding agent product, to AWS and powers Amazon Bedrock Managed Agents with OpenAI models, giving AWS a way to sell OpenAI through the same security, billing, and orchestration systems many enterprise customers already use.
The speed is the real tell. OpenAI said Microsoft remains its primary cloud partner, but it also said Microsoft's license is now non-exclusive and that OpenAI can serve all its products across any cloud provider. AWS used that opening almost immediately. In a separate product note, AWS said Codex on Bedrock will be available through the Codex command-line tool, desktop app, and VS Code extension.
For AWS customers, the product pitch is simple: buy OpenAI where you already run everything else. Amazon said Bedrock customers will, for the first time, be able to access OpenAI frontier models through the same services they already use for model access, fine-tuning, and orchestration. Reuters reported that AWS chief executive Matt Garman said customers will no longer have to leave AWS to find the AI models they want.
That does not end Microsoft's central role. Reuters reported that Microsoft still gets a guaranteed 20 percent cut of OpenAI revenue through 2030, subject to a cap, and that OpenAI's commitment to spend at least $250 billion on Azure by 2032 remains in place. The amended deal weakens exclusivity, not the broader financial bond.
The wider Amazon relationship shows why this is more than storefront politics. Reuters reported that Amazon invested $50 billion in OpenAI, that OpenAI committed to spend $100 billion on AWS over the next eight years, and that the companies agreed OpenAI would use two gigawatts of computing powered by Amazon's Trainium AI chips. Amazon is not only reselling OpenAI. It is also trying to become part of the infrastructure underneath OpenAI.
There are still reasons to stay skeptical. The new Bedrock offerings are in limited preview, not broad release, and Microsoft is still the primary cloud partner named in OpenAI's own announcement. But AWS has already turned OpenAI's newly looser cloud posture into an enterprise distribution channel. What to watch next is whether big companies actually shift OpenAI spending into Bedrock, or whether Microsoft's existing economics and Azure commitments keep most of that demand where it already is.
