2. §2Otherwise, this market will resolve to "No".
3. §3Anthropic's latest Claude Fable model means the model with the highest version number among models by Anthropic explicitly named Fable, such as Claude Fable 5 or Claude Fable 5.1, that have a standard output token price listed on Anthropic's official API pricing page.
4. §4If more than one such model shares the highest version number, the most recently released of them applies.
5. §5Only models that are publicly accessible, including via open beta or open rolling waitlist signups, will be considered; models available only through a closed beta or any form of private or limited access will not qualify.
