Research answer

Based on the supplied evidence, I can’t verify that GPT Image 2 is more photorealistic than GPT Image 1.5. The strongest accurate conclusion is: Insufficient evidence.[1][2][3][6][7][33]

What the evidence does show

  • The provided OpenAI documentation includes a model page for GPT Image 1.5 and general docs for image generation and image editing APIs.[1][2][3]
  • The API reference and cookbook materials discuss capabilities such as generating and editing images with GPT image models, but the supplied snippets do not provide any official photorealism benchmark or direct comparison between GPT Image 1.5 and GPT Image 2.[1][3][6][7]
  • None of the supplied OpenAI sources explicitly states that GPT Image 2 is more photorealistic than GPT Image 1.5.[1][2][3][6][7]

Evidence limits

  • The only non-OpenAI item provided is a Reddit post about GPT-Image-1.5 claiming leaderboard success, but it is not an official benchmark source and its snippet does not address GPT Image 2 or photorealism directly.[33]
  • Because the supplied evidence does not include a primary source for GPT Image 2 or a head-to-head evaluation, a factual “yes” or “no” would go beyond the evidence.[1][2][3][6][7][33]

Verdict

  • Fact-check result: Insufficient evidence to claim that GPT Image 2 is more photorealistic than GPT Image 1.5.[1][2][3][6][7][33]

If you want, I can next help you turn this into a stricter fact-check format like Claim / Evidence / Rating using only these same sources.
