It did not include the provenance needed to authenticate a public model release.\n- The 1M label was not unique: Anthropic's current documentation gives Fable 5, Opus 4.8, and Sonnet 5 full 1M-token context windows.\n- The production risk is not merely believing a rumor. It is allowing an unverified name to create retries, hidden fallback, bad cost attribution, and contaminated evaluation data.\n- A new model should pass identity, access, contract, compatibility, observability, canary, and rollback checks before it becomes routable.\n        \n        ","thumbnail_url":"https://img.transistorcdn.com/KyA01h2FD2insgk-wX_xzV6vbJnTNl2BvPYVL-XaI9A/rs:fill:0:0:1/w:400/h:400/q:60/mb:500000/aHR0cHM6Ly9pbWct/dXBsb2FkLXByb2R1/Y3Rpb24udHJhbnNp/c3Rvci5mbS9zaG93/LzQxMjcyLzE2ODM1/ODI0ODgtYXJ0d29y/ay5qcGc.webp","thumbnail_width":300,"thumbnail_height":300}
