OpenAI's release of GPT-6 Sol and GPT-6 Luna on September 22, 2026, underscores its control over the GPT model family and sets expectations for incremental Sol-tier updates such as 6.1 or higher. These models extend the capabilities introduced in GPT-6 Astra earlier in September, delivering improved reasoning, coding, and efficiency at roughly half the cost of GPT-5.6 equivalents through optimized inference and caching. The company's largest training run to date, exceeding 100,000 GPUs, and focus on alignment refinements after prior cybersecurity concerns support continued rapid iteration. While competitors like Anthropic launched Claude Opus 5.5 on the same day, GPT-branded releases remain OpenAI-exclusive, with upcoming catalysts including potential point releases or expanded API tiers that could influence trader views on timelines and feature thresholds.

A qualifying model must have a name or model identifier that includes "GPT" and "Sol" and be designated as version 6.1 or higher, regardless of capitalization or surrounding prefixes, suffixes, dates, or descriptors. For example, a version 6.1 or higher named in the same manner as GPT-5.6 Sol or GPT-6 Sol would qualify, including a new whole-number generation such as GPT-7 Sol or an Astra-branded release meeting these criteria, while models whose name does not include "Sol" or which retain a version designation below 6.1, such as GPT-6 Sol (released September 22, 2026), including any rollout, promotion, or snapshot of it, GPT-6 Luna, or GPT-6 Astra, will not qualify. Fine-tunes, modes, or restricted-access variants of an existing version, such as GPT-5.6-Cyber or GPT-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.
