Key point

OpenAI's GPT-5.4 is available in limited preview on AWS Bedrock and AgentCore.

Details

OpenAI's flagship models have officially become available on AWS Bedrock's managed inference and agent platform.

According to AWS, enterprises can now connect to the models through Bedrock without using the OpenAI API directly, which can reduce security policy, data privacy, and data sovereignty concerns.

  • Available in Bedrock Managed Agents
  • Also supported in AgentCore
  • Codex code agent integration provided

This is currently in the limited preview stage, with GPT-5.4 opening first. According to AWS CEO Matt Garman, GPT-5.5 will be available within a few weeks.

Behind this is the new funding commitment of up to $35 billion announced in February, for which OpenAI needs to operate 2GW of Trainium accelerators.

Following the realignment of its relationship with Microsoft, OpenAI is able to expand collaboration with other infrastructure partners such as AWS while keeping Microsoft as its primary cloud partner.
