## Content Report

**Content Title:** Model: Claude Sonnet 4
**Content URL:** https://aws-samples.github.io/sample-amazon-bedrock-central/models/anthropic-claude-sonnet-4

## Description

1. If I apply model availability according to Region in this, https://aws-samples.github.io/sample-amazon-bedrock-central/models/anthropic-claude-sonnet-4 with: ap-south-2, I can see Claude Sonnet 4, but not in ap-south-1.
2. Where as this document shows: https://docs.aws.amazon.com/bedrock/latest/userguide/model-card-anthropic-claude-sonnet-4.html, it is available in both region: ap-south-1 and ap-south-2.
3. And this another document: https://docs.aws.amazon.com/bedrock/latest/userguide/models-region-compatibility.html, it shows both models are not available in-region.
**Which is the source of truth?**

Start by comparing the sample page for Claude Sonnet 4 with the two linked AWS Bedrock documents, focusing on ap-south-1 and ap-south-2 availability. Determine which source is authoritative, then reconcile the model page with that source and verify both regional results are consistent.
