"Effective immediately, by moving Claude Opus 4.1 into the Legacy state [2], Anthropic is initiating the deprecation process for this model. Once the model enters the Legacy state, no additional Service Quota increases will be granted for the model. Opus 4.1 will stay in the Legacy state until October 8, 2026, when the model will enter the Extended Access state. On January 8, 2027, the model will go end-of-life and will no longer be accessible in Amazon Bedrock."
