Incorrect Claude 4.x model names on AI docs pages

[hfurkanbozkurt]

Problem

The Amplify docs AI pages use Claude [VERSION] [SIZE] format for Claude 4+ models (e.g., Claude 4.5 Haiku), but the actual a.ai.model() accepted strings use Claude [SIZE] [VERSION] (e.g., Claude Haiku 4.5).

This matches the Bedrock naming convention change for post-4 models (Bedrock model cards).

Source of truth

ModelType.ts defines the accepted strings:

// 3.x — VERSION then SIZE (correct in docs)
'Claude 3.5 Haiku'
'Claude 3.5 Sonnet'

// 4+ — SIZE then VERSION (wrong in docs)
'Claude Opus 4'
'Claude Sonnet 4'
'Claude Haiku 4.5'
'Claude Sonnet 4.5'
'Claude Opus 4.5'
'Claude Sonnet 4.6'
'Claude Opus 4.6'

Affected pages

• https://docs.amplify.aws/react/ai/set-up-ai/
• https://docs.amplify.aws/react/ai/concepts/
• Any page showing a.ai.model() examples

Expected

Docs should show Claude Haiku 4.5 (not Claude 4.5 Haiku) to match the code and Bedrock naming.

Users copying from docs will get a TypeScript compile error since the string doesn't match keyof typeof supportedModelsLookup.
