What is GPT-5.6 Sol? #
GPT-5.6 Sol is an upcoming next-generation model from OpenAI, officially previewed on June 26, 2026 but not yet released. OpenAI says it brings stronger capabilities in coding, science, and cybersecurity, paired with the company's most advanced safety stack. It is positioned as the next step in the GPT-5 line, arriving amid a competitive race with Google's rumored Gemini 3.5 Pro.
OpenAI's preview points to gains in coding, science, and cybersecurity alongside its most advanced safety stack. Early unverified reports claim GPT-5.6 Sol works slower, fails more often, and writes less code than Claude Opus in short sessions, but surpasses it in speedup after roughly 30 hours of work. Rumors from early July 2026, citing pre-access testers at NVIDIA and OpenAI, suggested a release was imminent within days.
