  • Compared to Dolly 3, the new generator produces more realistic images.
  • Examples: A grand library, vibrant butterflies, and close-up portraits.

Practical Use Cases

• YouTube Thumbnails:

  • Generates thumbnails with techy backgrounds and specific elements (e.g., glowing logos).
  • Faces are not perfectly replicated; still a work-in-progress for exact likeness.

• Infographics:

  • Good at generating infographics with detailed text, such as the evolution of video games.

• Memes:

  • Allows for correction of cropped text and provides download options for social media.

Future Updates

• Plans to update prompt books and create further instructional videos as more experience is gained.
• Emphasis on continued testing and refinement of the image generation feature.

Conclusion

• The new image generation in ChatGPT shows significant improvements over Dolly models.
• While some limitations remain, the feature presents a powerful tool for creative and practical purposes.
