Model & inference profile IDs
Base model ID — direct on-demand invoke
Cross-region inference profiles (5)
Regions marked Inference profile only require a profile ID rather than the base model ID — invoking the base ID there returns a validation error. Regional (us., eu.) profiles carry a 10% premium over global.

Common questions
- How much does Claude Sonnet 4.5 cost on Amazon Bedrock?
- $3.00 per 1M input tokens and $15.00 per 1M output tokens in us-east-1. Cached input reads at $0.300, roughly a tenth of the input rate, which dominates the bill on agentic workloads that re-send a long prefix.
- Which AWS regions support Claude Sonnet 4.5?
- 16 of 16 regions: us-east-1, us-east-2, us-west-2, ca-central-1, eu-west-1, eu-west-2, eu-west-3, eu-central-1, eu-north-1, ap-southeast-1, ap-southeast-2, ap-northeast-1, ap-northeast-2, ap-northeast-3, ap-south-1, sa-east-1. Regions marked profile-only need a cross-region inference profile ID such as au.anthropic.claude-sonnet-4-5-20250929-v1:0 rather than the bare model ID.
- What is the context window of Claude Sonnet 4.5?
- 200,000 tokens (200K).
- What is the model ID for Claude Sonnet 4.5 on Bedrock?
- anthropic.claude-sonnet-4-5-20250929-v1:0. In regions where it is only reachable through a cross-region inference profile, use a prefixed ID instead: au.anthropic.claude-sonnet-4-5-20250929-v1:0, eu.anthropic.claude-sonnet-4-5-20250929-v1:0, global.anthropic.claude-sonnet-4-5-20250929-v1:0.
