OpenAI has released a preview of GPT-5.6 Sol, a next-generation model that the company says delivers stronger capabilities in coding, science, and cybersecurity. The preview frames the model as a step forward in performance across technically demanding domains, rather than a broad general-purpose update.
Alongside the capability gains, OpenAI is emphasizing safety. GPT-5.6 Sol is paired with what the company describes as its most advanced safety stack, suggesting that the model's release is as much about risk management as it is about raw performance. The source does not provide independent benchmarks or third-party evaluations, so the claims currently rest on OpenAI's own description.
