The August 5 platform release notes confirm no serving at all, with Anthropic recommending Opus 5 and pointing researchers to the External Researcher Access Program. Anyone with that pinned model ID in production config or an eval harness breaks today rather than degrading gracefully. Go grep your repos for the 2025-08-05 snapshot string. I found one in an old eval script.
