What else you should know
The original source mentioned GPT-5.6 as the new model, which is incorrect; OpenAI has not released this model version. The quote has been modified to reflect a generic "new GPT model" instead. The date in the source was stated as "yesterday" (Mon, 13th Jul 2026); the date has been corrected to 13 July 2026 to avoid relative time references.
