The BedrockFoundationModel class has no predefined constant for Anthropic's Claude Sonnet 5 (anthropic.claude-sonnet-5), which is generally available on Amazon Bedrock. The FoundationModelIdentifier class in aws-cdk-lib gained this model in aws#38272, but the alpha module was not updated alongside it, so referencing Claude Sonnet 5 through the L2 Bedrock constructs requires hand-constructing the model definition. Adds ANTHROPIC_CLAUDE_SONNET_5 with the same model id as the aws-cdk-lib counterpart and the same capability flags as its Sonnet predecessors (supportsAgents, supportsCrossRegion, optimizedForAgents), following the pattern of the Claude Opus 4.8 addition (aws#38038). Closes aws#38556.
…odels Adds the remaining Claude 5 family models to the predefined model constants, verified against the Amazon Bedrock model cards: - FoundationModelIdentifier (aws-cdk-lib/aws-bedrock) gains ANTHROPIC_CLAUDE_OPUS_5 (anthropic.claude-opus-5), ANTHROPIC_CLAUDE_MYTHOS_5 (anthropic.claude-mythos-5), and ANTHROPIC_CLAUDE_FABLE_5 (anthropic.claude-fable-5), following aws#38272. - BedrockFoundationModel (@aws-cdk/aws-bedrock-alpha) gains ANTHROPIC_CLAUDE_OPUS_5 and ANTHROPIC_CLAUDE_FABLE_5 with supportsAgents and supportsCrossRegion per the model cards, following aws#38038 and aws#38557. Fable 5's doc notes the provider_data_share data retention opt-in its model card requires. Mythos 5 is deliberately excluded from the alpha module: per its model card it supports neither Bedrock Agents nor Invoke/Converse (bedrock-mantle Messages API only, Preview, single region), so a BedrockFoundationModel constant would not be usable with the constructs that class serves. The plain identifier in aws-cdk-lib gives users a canonical reference. Closes aws#38570.

Issue # (if applicable)
Closes #38570.
Reason for this change
The Claude 5 family on Amazon Bedrock includes Claude Opus 5, Claude Fable 5, and Claude Mythos 5, none of which have predefined constants in
FoundationModelIdentifier(aws-cdk-lib/aws-bedrock) orBedrockFoundationModel(@aws-cdk/aws-bedrock-alpha). Sonnet 5 was covered by #38272 and #38557. Prompted by review feedback from @lpizzinidev on #38557.Description of changes

Description of how you validated changes
All 534 tests in the alpha module and the aws-bedrock tests in
aws-cdk-libpass. Purely additive constants; no behavior changes. No integration test or README change, consistent with prior model-constant additions (#38038, #38557).Checklist
Credit to @lpizzinidev for flagging the missing models on #38557.
