**OpenAI’s GPT-5.6 Sol family (flagship Sol, plus Terra and Luna tiers) reached limited preview on June 26, 2026, and general availability on July 9 after a U.S. government-requested delay over cybersecurity concerns.** The models introduced new naming, “max” and “ultra” reasoning modes, stronger agentic performance in coding and long-horizon tasks, and competitive cybersecurity benchmarks at lower token cost than rivals. As of late August 2026, OpenAI has continued iterating on 5.6 with ultrafast mode and pricing reductions while naming internal next-generation work “Astra,” described as the subsequent major model with advanced math and theoretical computer science results. No release date, model card, or confirmation of a 5.7+ or GPT-6 designation has been issued. Traders weigh OpenAI’s recent multi-month cadence, ongoing safety and regulatory reviews, and the absence of concrete timelines against historical patterns when assessing probabilities for a near-term 5.7+ Sol release.

This market will resolve to "Yes" if OpenAI's next GPT Sol 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 "Sol" 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 Sol would qualify, including a new whole-number generation such as GPT-6 Sol or an Astra-branded release meeting these criteria, while models whose name does not include "Sol" or which retain a version designation below 5.7, such as GPT-5.6 Sol, GPT-5.6 Terra, or GPT-5.6 Luna, 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.
The primary resolution source for this market will be official information from OpenAI, with additional verification from a consensus of credible reporting.**OpenAI’s GPT-5.6 Sol family (flagship Sol, plus Terra and Luna tiers) reached limited preview on June 26, 2026, and general availability on July 9 after a U.S. government-requested delay over cybersecurity concerns.** The models introduced new naming, “max” and “ultra” reasoning modes, stronger agentic performance in coding and long-horizon tasks, and competitive cybersecurity benchmarks at lower token cost than rivals.
