Two new model IDs, claude-mashmallow-eap and claude-melon-eap, have been spotted in the system, suggesting an imminent release from Anthropic. Speculation points towards an update to Opus or possibly a new Haiku model. Reports indicate these are capable models rather than fiction-focused ones, with an official announcement expected potentially next week.
