Market Overview

An objective analysis of the three dominant models reshaping software engineering velocity and capability in the post-GPT-4 era.

GEMINI 3

Visual & Design

Dominates design and visual understanding. Notable for creating complex 3JS simulations and nuclear plant demos directly from prompts.

OPUS 4.5

Logic Core

Leading coding logic engine. Developers report feeling "6 to 12 months away from solving software" completely.

GPT 5.2

Code Red

OpenAI's direct response to market pressure. Released immediately following an internal "Code Red" to reclaim dominance.
