GPT-6 Sol (Global)

GPT-6 Sol is part of OpenAI's GPT-6 family of models, which OpenAI expanded on September 22, 2026 by introducing Sol alongside GPT-6 Luna. The family already included GPT-6 Astra, and Sol represents OpenAI's effort to extend the lineage to a broader range of everyday work scenarios. OpenAI positions Sol as one of two complementary variants unveiled that day, suggesting a design philosophy oriented around practical utility rather than the more research-intensive positioning of Astra.

OpenAI announced GPT-6 Sol with the intent of bringing frontier-level intelligence to routine professional tasks, framing it within a family that has emphasized advances in reasoning, professional work, and tool use across previous releases. Sol is intended for users who need capable general assistance for daily workflows, building on the same underlying GPT-6 research direction that powers Astra's strengths in computer use, software engineering, and professional domains. As a member of the GPT-6 line, Sol fits teams and developers who want a balance of capability and accessibility for everyday applications.
