On 2026-10-05 Anthropic announced Claude Opus 5, Sonnet 5 and Haiku 4.5 are live with in-country inference in India via an Amazon Bedrock India geographic cross-Region profile that routes only between Mumbai (ap-south-1) and Hyderabad (ap-south-2), delivering its August data-residency commitment for regulated Indian customers.

Key Takeaways

  • ✓Models: Claude Opus 5, Sonnet 5, Haiku 4.5 via the Bedrock India geographic inference profile
  • ✓Routing only between ap-south-1 (Mumbai) and ap-south-2 (Hyderabad); no data stored in destination Region; Bedrock zero data retention by default
  • ✓Model IDs use the in. prefix (e.g. in.anthropic.claude-sonnet-5); Messages API, InvokeModel, Converse, Guardrails and prompt routing supported
  • ✓Same AWS batch (Sep 29): in-region Opus 5/Sonnet 5 in Seoul and Sonnet 5 in Singapore
  • ✓Adoption per Economic Times: TCS rolling Claude to 50,000 staff; NPCI building its AiNxt agent platform on Claude

In-Depth Technical Analysis

Background

India is one of Claude's largest markets, but regulated banks, insurers and government bodies need requests processed in-country. Anthropic committed in August and delivered on 2026-10-05.

How it works

An Amazon Bedrock India geographic cross-Region inference profile routes requests only between ap-south-1 (Mumbai) and ap-south-2 (Hyderabad). Data is encrypted in transit, not stored in the destination Region, and Bedrock applies zero data retention by default. Billing, quotas, CloudWatch and CloudTrail stay in the source Region.

Benchmarks

This is an availability/data-residency launch; no India-endpoint latency or throughput numbers were published.

Getting started

Use region_name="ap-south-1" with model IDs like in.anthropic.claude-sonnet-5 or in.anthropic.claude-opus-5 via Converse/InvokeModel, or the Anthropic SDK with aws_bedrock_token_generator and base URL https://bedrock-runtime.ap-south-1.amazonaws.com/anthropic. The same AWS batch added in-region Opus 5/Sonnet 5 in Seoul and Sonnet 5 in Singapore.
