OpenAI 登陸 AWS Bedrock — ChatGPT 的獨佔是否就此終結
openai 的 gpt-5.5 和 gpt-5.4 現已登陸 aws bedrock，為企業客戶提供了一種無需直接與 openai 簽約即可訪問前沿模型的方式。
openai has launched gpt-5.5, gpt-5.4, and codex on amazon web services, hosted on the new bedrock inference engine in us commercial and govcloud regions. aws confirms pricing is identical to openai's first-party rates with no markup, and usage integrates seamlessly into existing aws contracts for simplified billing. the move leverages aws security capabilities like iam and vpc isolation, allowing highly regulated sectors to adopt generative ai more easily. this distribution deal signals a major shift in go-to-market strategies, opening frontier model access to the massive aws ecosystem.
