- On **July 15, 2026**, the current Anthropic, Google Cloud, and Cursor catalogs listed Claude Fable 5, Claude Opus 4.8, and Claude Sonnet 5—not Claude Opus 5 or Honeycomb.

- A circulated Cursor-like screenshot showed “Honeycomb EAP,” a 1M context window, extra-high effort, per-turn controls, and safety fallbacks. It did not include the provenance needed to authenticate a public model release.

- The 1M label was not unique: Anthropic's current documentation gives Fable 5, Opus 4.8, and Sonnet 5 full 1M-token context windows.

- 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.

- A new model should pass identity, access, contract, compatibility, observability, canary, and rollback checks before it becomes routable.
