  "disclaimer": "This is the OpenAI-to-Bedrock MIGRATION target catalog, not a list of OpenAI models: it holds the verified landing candidates for the available paths. Verified 2026-08-21 — the GPT-5.6 family changed materially between 2026-07-21 and 2026-08-21: Sol/Terra/Luna now ALSO run on bedrock-runtime via CRIS inference profiles (Geo us./in., Global global.), with Converse/Chat Completions/Invoke listed as supported there (Guardrails Converse-only, prompt caching Responses-only on runtime), and Global CRIS pricing published at OpenAI's standard list price (cost parity; In-Region/Geo remain 1.10x). So runtime_converse now carries BOTH same-vendor GPT-5.6 candidates (same-model governance path) AND the Claude tier mapping (GPT-5.6 Sol -> Claude Opus 4.8, Terra/5.5/5.4 -> Claude Sonnet 5, Luna -> Claude Haiku 4.5) as the cross-family option. GPT-5.5 and GPT-5.4 remain mantle-only and in-region only — no CRIS, no runtime path. The gpt-oss open-weight models still support Converse on bedrock-runtime but sit a capability class below the frontier tier and are not listed. Only models with dated evidence are listed; entries name their evidence. Numeric limits stay 'unknown' unless sourced. Re-probe every selected model and API path in the target account and region before implementation.",
