Anthropic names Claude model tiers with single words: poetic forms first (Haiku, Sonnet, Opus), then narrative/myth forms (Fable, Mythos). This market tracks which new words join that series.

Each answer is a candidate in the form "Claude [Word]". Add your own. Answers are independent, so more than one can resolve YES.

An answer resolves YES when its word first appears as an official Claude tier or family name in any of: the Anthropic model docs (docs.claude.com), an anthropic.com blog or launch post, or a live API model string.

Rules:

• Counts: any new single word used as a Claude tier or family name.

• Does not count (already in use): Haiku, Sonnet, Opus, Fable, Mythos.

• Version numbers are ignored. "Claude Saga 5" resolves the "Claude Saga" answer.

• Internal tiers count once Anthropic officially names them, even if not publicly released (e.g. a named-but-gated tier listed in the docs).

• Matching is case-insensitive and on the word itself. An obvious spelling variant (singular/plural) resolves the nearest existing answer.

• Names launching together each resolve their own answer YES.
  

Close: Dec 31, 2029. Realized names resolve YES as they appear. Any answer with no official use by the close date resolves NO.
