Anthropic’s Claude Opus 5.5 lands on AWS Bedrock, raising the bar for long‑running AI agents

Amazon Web Services announced on September 28 that Anthropic’s newest large language model, Claude Opus 5.5, is now available on its generative AI platform Amazon Bedrock. Claude, similar in concept to ChatGPT, powers tasks such as text generation, long‑form summarization, and code assistance, with an emphasis on reliability and safety controls.

Opus 5.5 is positioned as Anthropic’s top‑tier model for demanding use cases: autonomous AI agents that run for hours, complex software development, and knowledge‑heavy workflows. Through Bedrock, customers can mix and match Opus 5.5 with other foundation models under a single API, making it easier to experiment and standardize on multi‑model architectures.

The model is also accessible via the dedicated Claude Platform on AWS, widening the range of enterprise‑grade options available on Amazon’s cloud. As advanced models increasingly arrive as cloud‑hosted services rather than standalone products, enterprises are being pushed to think not only about “which model is best,” but also “which cloud gives us the most secure and manageable way to deploy AI across the organization.”
