Amazon Bedrock's lifecycle page lists Claude Sonnet 4.5 as Legacy: extended access, possibly at a higher price, starts January 8, 2027, and end of life is April 8, 2027
Amazon Bedrock's lifecycle page lists Anthropic's Claude Sonnet 4.5 as a Legacy model. Its table gives January 8, 2027 for public extended access, when Amazon says to expect higher pricing, and April 8, 2027 for end of life, on or soon after which requests will fail absent a private arrangement with the provider. Amazon says to migrate by updating application code before that date.
