On May 17th, the Claude Mythos base model showed up on Google Cloud's quota and system limits list — but this time, the model option had its 'Preview' tag stripped. Developers say it wasn't even on the list a day earlier.

Claude Opus 4.7 pulled the same trick before its official launch: it appeared in the Google Cloud console without the preview label right before going public. History seems to be repeating itself, which means the previously restricted Claude Mythos could be headed for a full public rollout very soon.
