OpenAI GPT-5.5 and Codex reach general availability on Amazon Bedrock

OpenAI’s GPT-5.5, GPT-5.4, and Codex are now generally available through Amazon Bedrock.

For enterprise buyers, the important part is access and procurement. Usage can count toward AWS commitments, pricing matches direct OpenAI rates, and GPT-5.4 is available in AWS GovCloud.

The release also shows how quickly frontier model distribution is becoming a cloud marketplace fight, with major labs trying to meet customers where their infrastructure budgets already sit.
