Summary

AWS Launches GPT-5.5

AWS Bedrock now hosts OpenAI’s GPT-5.5, Codex and Managed Agents with encryption and audit logs, so data will not train OpenAI models.
Early users say costs are 15-30% lower than Azure because of AWS reserved capacity and scale.
Managed Agents provide steering, memory of past interactions and enterprise-grade security for production AI assistants.
AWS AI services generated over $15 billion annualised revenue in Q1, lifting overall AWS growth above 20%.

History

Historical Context

In 2019 Microsoft pledged $1 billion to OpenAI, taking a 27 % equity stake and making Azure the exclusive cloud platform. The deal built on Microsoft’s cloud-first strategy under Satya Nadella, which had accelerated Azure services such as Azure Information Protection since 2016. After years of competition, Microsoft now ends the exclusivity, opening OpenAI to other providers.
