OpenAI began a staged release of GPT-5.6 Sol, initially through API and Codex access for selected trusted partners and organizations. The original announcement did not give a firm public launch date.
Its published comparisons emphasized improvements over GPT-5.5 in coding and professional tasks, alongside stronger safeguards. This post records the June preview; it should not be used to infer which models are available to your account today.
My personal impression was that models were becoming more capable and precise while losing some of the expressive, emotionally engaging style of older versions. That is a preference about conversation, rather than a benchmark result.
