OpenAI has confirmed the global public launch of its GPT-5.6 model family for this Thursday. The release includes the base Sol model and the Terra and Luna variants.
This move ends a limited preview period that began in late June, which was restricted to select U.S. government-approved organizations. Market observers note the timing aligns with expectations for an early July release.
The launch is anticipated to impact the competitive landscape, coinciding with the scheduled end of subscription tiers for Anthropic's Claude Fable 5.
