Agent Reasoning and Citations

Agent Reasoning ChatGPT 5.4 includes a reasoning dropdown that lets you view a high-level summary of how the model arrived at its answer. This section highlights key steps, assumptions, and factors considered—without exposing full internal chain-of-thought—so you can better understand the logic behind the response.

Citations When applicable, responses include citations that point to supporting sources (e.g., web pages, documents, or data). These appear inline and help you:

• Verify accuracy

• Explore sources in more detail

• Distinguish grounded information from general knowledge

Together, the reasoning summary and citations improve transparency and trust in model outputs while keeping explanations clear and usable.
