What GPT Image 2.5 is good at

GPT Image 2.5 is OpenAI’s current image model and holds the top two places on the Arena text-to-image leaderboard. Phosphene runs both versions: Flare for fast everyday work, Sunburst when the result is the final asset.

Strong at

  • Following long, specific prompts without dropping details
  • Exact text on packaging, posters and UI mockups
  • Editing a reference photo while keeping the face, product and layout
  • Product shots and brand assets that need to look finished

Keep in mind

  • Sunburst takes around 20 seconds per image; Flare is the quick option
  • Five aspect ratios only (square, 3:4, 4:3, 9:16, 16:9)
