Availability notes
Not generally available. At announcement, only some cyber defenders and trusted partners in the Fairwind Program (ID listed in the pricing table). The official model list for Claude Code / Codex (checked 2026-11-12) contains only Anthropic / OpenAI models, respectively, so both are false.
