OpenAI’s July 9, 2026 public release of the GPT-5.6 family (Sol flagship, Terra balanced, and Luna cost-efficient tiers) established a durable naming convention that decouples capability levels from generation numbers, allowing independent updates to Luna without a full Sol refresh. Trader focus on a 5.7+ Luna release stems from credible leaks in mid-July pointing to an August target with larger context windows, multi-agent improvements, and infrastructure gains, alongside a recent August 9 unveiling of an internal “Doug” model slated for November rollout. Competitive pressure from rival labs, ongoing U.S. government safety reviews that briefly delayed 5.6, and OpenAI’s pattern of quarterly-tiered updates continue to shape expectations, while the absence of any official 5.7 timeline keeps probabilities sensitive to new announcements or earnings commentary.

This market will resolve to "Yes" if OpenAI's next GPT Luna model (5.7+) is made available to the general public between market creation and the specified date (ET). Otherwise, this market will resolve to "No".
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, or GPT-5.6 Terra, 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. The release must either be clearly defined and publicly announced by OpenAI as accessible to the general public, or otherwise be made publicly accessible and explicitly labeled on the company's official website. Labeling errors, placeholder text, or version names displayed on the website that do not correspond to a model that is actually accessible to the general public will not qualify.
