GPT Image 2.5 Real-World Test: How Clear Is 4K? Full Test of Skin, Fingers, Photo Retouching, and Heavenly Palace Scenes

What exactly did GPT Image 2.5 upgrade? This episode does a full hands-on test!

We will test underwater figures, real skin, fingers and toes, eye close-ups, image editing, character consistency, batch generation, 1000 glass spheres, and scenes of ancient Chinese mythological Heavenly Palace. We also compare the generation of ChatGPT versus Codex, and experience GPT Image 2.5 Sunburst highest-quality, 21:9, 4K images through Higgsfield, to see just how clear they are when zoomed in.

Test focus:

• Is character skin more realistic

• Are fingers, toes, and details accurate

• Noise performance after 500% zoom

• What's the difference between Sunburst and Flare

• Can it continuously generate 10 images in a unified style

• 21:9 highest-quality 4K result

• Is Codex generation more stunning

Some tests still show four fingers, six toes, and deformed pupils, so this isn't simply showing off strengths — it's a complete, honest review that doesn't hide failures.
