AWS Bedrock Provider Shape

Last updated: dev@28d27ee | 2026-07-17

Scope

Canonical provider ID bedrock; UI/provider mapping currently recognizes AWS Bedrock, but the canonical layer has no native Bedrock runtime reader.

Shape

Bedrock is not generally an OpenAI-compatible host: model IDs, inference profiles, request/response unions, signing, and per-family payloads differ. Only an explicitly configured OpenAI/Anthropic-compatible gateway may use those dialects. Native Bedrock capability must come from a versioned Bedrock model catalog plus exact foundation-model/inference-profile identity.

Fallback And Current Gaps

Do not classify all amazonaws.com hosts as Bedrock; use explicit kind or a future region-aware exact host/path shape. General fallback is safe only behind an explicitly compatible gateway. Native signing, catalogs, and family payload mappings remain unimplemented.
