GPT Image 1 (April 2025) had unreliable text and square-only output. GPT Image 1.5 (December 2025) improved quality and added limited aspect ratios but was slow (12-20 seconds) and had a yellow color cast. GPT Image 2 (April 2026) achieves ~99% text accuracy, 2K resolution, 3-5 second generation, multilingual support, thinking mode, and multi-image consistency — a generational leap.
