PolymarketRules
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.
