In late June 2026, OpenAI plans to release its new flagship model, GPT-5.6, available in mini, standard, and Pro versions. The model's context window has been expanded to 1.5 million tokens, a 43% increase, with token efficiency improved by 10% to 15%. It features core capabilities such as handling complex tasks, supporting coding workflows, 3D content generation, cross-platform operations, and browser automation, primarily targeting enterprise-level AI assistants and development scenarios.
