Manifold MarketsRules
This market will resolve according to the calendar date (ET) on which OpenAI's next GPT Luna model (5.7+) is made available to the general public.
- A qualifying model must have a name or model identifier that includes "GPT" and "Luna" and be designated as version 5.7 or higher, regardless of capitalization or surrounding prefixes, suffixes, dates, or descriptors.
- For example, a version 5.7 or higher named in the same manner as GPT-5.6 Luna would qualify, including a new whole-number generation such as GPT-6 Luna or an Astra-branded release meeting these criteria, while models whose name does not include "Luna" or which retain a version designation below 5.7, such as GPT-5.6 Luna, GPT-5.6 Sol, GPT-5.6 Terra, or GPT-6 Astra (released September 4, 2026), will not qualify.
- Fine-tunes, modes, or restricted-access variants of an existing version, such as GPT-5.6-Cyber or GPT-5.6 Sol Ultrafast, will not qualify.
- A qualifying model must be launched and publicly accessible, including via open beta or open rolling waitlist signups.
- A closed beta or any form of private access will not suffice.
