Bottom Line
Catalog updated: August 2026
Gamma and GPT Image 2 both compete in Design, overlapping most directly on design. Gamma runs on a freemium model while GPT Image 2 runs on a paid-only plan, which alone may settle it if budget or a free tier is a hard requirement.
Choose Gamma if…
Best for anyone who needs a presentable slide deck fast and doesn't want to fight with formatting, and its edge is generates a fully designed deck from a prompt or outline, output quality well above what you'd expect from AI. Excellent for internal decks and first drafts, plan to move to Figma or PowerPoint for anything client-facing and final. Lean toward GPT Image 2 instead if image generation and editing with flexible sizes and high-fidelity image inputs in OpenAI’s developer API matters more for your use case.

Lean toward Gamma instead if generates a fully designed deck from a prompt or outline, output quality well above what you'd expect from AI matters more for your use case.
