OpenAI 登陆 AWS Bedrock — ChatGPT 的垄断是否就此终结
openai 的 gpt-5.5 和 gpt-5.4 现已登陆 aws bedrock，为企业客户提供了一种无需直接与 openai 签约即可访问前沿模型的方式。
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.
