OpenAI's GPT-5.6 family, released in limited preview on June 26, 2026, and expanded to general availability on July 9 after U.S. government safety review, introduced Luna as the fastest, lowest-cost tier alongside mid-tier Terra and flagship Sol. Luna quickly became the default for free and Go users by early August while supporting expanded multi-agent workflows in mid-August updates. Rapid iteration across the GPT-5 series since 2025, combined with competitive pressure from Anthropic's models and efficiency gains in coding, agentic tasks, and cybersecurity benchmarks, shapes expectations for a 5.7+ successor. Traders monitor OpenAI's release cadence, any further regulatory gating, and enterprise feature expansions that could accelerate the next major model drop.

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.
The primary resolution source for this market will be official information from OpenAI, with additional verification from a consensus of credible reporting.
