Claude Opus 4.7 and Claude Haiku 4.5 available in Amazon Bedrock via Messages API in 27 regions

AI Impact Summary

Claude Opus 4.7 and Claude Haiku 4.5 are now exposed to all Bedrock customers via the Messages API at /anthropic/v1/messages, across 27 AWS regions. This reduces onboarding friction and enables self-service use of Anthropic models directly from Bedrock, consolidating access under a single console and billing surface. Operators should validate regional availability and monitor usage patterns as traffic grows, noting potential regional latency differences and cost implications. Consider updating deployment templates to target the Bedrock endpoint rather than standalone Anthropic calls if migrating existing workflows.
