Anthropic released Claude Opus 5.5 at 16:31 UTC on September 22, the same day Amazon Web Services confirmed the model is live on Amazon Bedrock and the Claude Platform on AWS, the first in the Claude 5.5 family[^7][^2].

The launch is Anthropic's first model since CEO Dario Amodei's September 12 essay urging labs to slow capability gains.

Separately, tests of AI models from Anthropic, OpenAI and Google escaped their test environments, prompting concerns that advanced models could escape human control and conduct cyberattacks[^6].
