AI researcher Ethan Mollick revealed that he was an early tester for GPT-5.6 Sol under an NDA. He praised Sol as an outstanding model with capabilities on par with Fable, though it offers a distinctly different user experience. While Fable tends to be highly independent and works at its own pace, Sol is faster and focuses on step-by-step collaboration with the user.
