About ChatGPT Image 1.5
GPT Image 1.5 is OpenAI's mid-cycle refresh of GPT Image 1 — same architecture, better training data, and tighter quality control on outputs. The main wins are higher base resolution, better photorealism, and noticeably reduced visual artifacts (over-smoothing, plasticky skin). Pricing is slightly higher than v1 but the quality jump justifies it for most use cases.
Heads up
Still slower than Flux-family models. If turnaround time is critical, GPT isn't the right family.
Best use cases for ChatGPT Image 1.5
Where this model produces meaningfully better output than alternatives.
Photorealistic outputs at higher resolution
Where v1 felt 720p, 1.5 feels 1080p. Cleaner edges and textures.
Skin and portrait work
V1's over-smoothing was the most common complaint. 1.5 keeps natural skin texture.
Mid-budget production work
When v1 is too rough but v2 is overkill, 1.5 is the goldilocks tier.
Editorial-quality edits
Good enough for blog headers, social posts, lookbooks — not quite ad-campaign tier.
Iterative refinement
Less cumulative degradation across multiple edits than v1.
Tips for great results with ChatGPT Image 1.5
Practical tricks based on how this specific model was trained.
1. Migrate from v1 silently
Why: 1.5 is fully backwards-compatible with v1 prompts. Easy upgrade.
2. Use for portraits where v1 looked plastic
Why: Skin texture preservation is the headline improvement.
3. Resolution-aware prompting
Why: 1.5 supports higher native resolution. Calling it out in the prompt pushes it to fully use that capacity.
Interior editing example
Same model, different task — adding a new element to an existing scene.
