# Thinking Mode

## Definition

A 10–20 second latency phase where the AI model plans composition, typography, and constraints before rendering pixels.

## Detail

Thinking Mode is the **observable manifestation** of [[concept-reasoning-stack-integration]]. When a user submits a prompt to a pro / reasoning model inside ChatGPT, the system spends roughly **10 to 20 seconds** explicitly 'thinking' before it begins to generate an image.

This latency is **not lag** — it is compute time dedicated to reasoning through:

- composition,
- typography hierarchy,
- object placement,
- and constraint satisfaction.

This phase replaces the human labor of sketching, wireframing, and planning. By the time the model commits to rendering a pixel, the structural logic of the image has already been fully resolved. This is the 'Think' step inside [[framework-new-generation-loop]].

## Contrast

This contrasts with the legacy 'instant mode' generation path — faster, but lacking the structural planning that enables single-prompt success on complex deliverables.
