Summary

OpenAI launches ChatGPT Image 1.5 with improved text clarity and photo realism, but the new model still lags behind Google's Nano Banana Pro in speed, accuracy, and overall image quality despite representing significant progress from previous versions.

Key Points

  • ChatGPT releases an improved Image 1.5 model with better text legibility and realistic photography capabilities, but still struggles with basic accuracy like correctly positioning arrows in water cycle diagrams
  • Google's Nano Banana Pro maintains its position as the superior AI image generator, producing faster generation times, more realistic images, and better overall quality compared to ChatGPT's offerings
  • OpenAI's new image model represents significant progress from previous versions but appears to be a competitive response to Google's technical advances rather than a breakthrough innovation
