  "description": "Foundation-model release + lifecycle registry, cross-referenced against CLI version releases. Sourced from vendor deprecation/lifecycle pages. Dated model IDs carry an exact release date; dateless IDs (Claude 4.6 generation onward) are pinned snapshots whose release date is filled from the vendor models API. Where a vendor accepts a different id at request time than the public one, requestable_id records the id to request (e.g. ChatGPT-auth Codex serves gpt-5.6 only as gpt-5.6-sol).",
