Codex Adds Instant Explanation Feature
soumitrashukla9 · x · 2026-07-11
The Codex app added a feature named More Details: selecting any text will pop up an instant explanation, invoking GPT-5.5 Instant to provide a more detailed breakdown of the highlighted content. Compared to opening a sidebar chat, this entry point requires no manual prompt input and retains the current thread's context, making it ideal for quickly querying concepts and reasoning details within an agent's output.
