What is the default Quality (--q) value in GPT Image?

GPT Image's default Quality (--q) is typically High / HD. This works well for general use, but specialized prompts often benefit from adjustment. See our recommended values above for different use cases.

Does Quality (--q) affect generation speed in GPT Image?

Yes — higher values generally increase generation time but improve output quality. Choose your value based on the quality level you need.

What Quality (--q) value is best for professional work?

For professional and commercial work, we recommend Maximum / --q 2. This ensures maximum quality while keeping generation practical.

Can I change Quality (--q) after generating in GPT Image?

No — Quality (--q) must be set before generation. However, you can quickly regenerate with a different Quality (--q) value using the same prompt to compare results side by side.

Values & Usage

Quality (--q): StandardStandard

Faster generation, good for iteration and testing

Quality (--q): High / HDHigh / HD

Better detail and consistency, recommended for final output

Quality (--q): Maximum / --q 2Maximum / --q 2

Highest quality available, slower but best results

Example Prompts

Demonstrating Quality (--q) at Standard — Faster generation, good for iteration and testing

beginner

Create a pixel art image of scenic composition featuring landscape. The composition should feel grand with sunset rim light. Use warm earth tones throughout. Every detail should be intentional — from the subject expression to the overall mood. The final result should look like a professional pixel art piece.

Demonstrating Quality (--q) at High / HD — Better detail and consistency, recommended for final output

beginner

Create a low poly image of scenic composition featuring landscape. The composition should feel intimate with neon ambient glow. Use analogous warm palette throughout. Every detail should be intentional — from the background atmosphere to the overall mood. The final result should look like a professional low poly piece.

Demonstrating Quality (--q) at Maximum / --q 2 — Highest quality available, slower but best results

intermediate

Create a art nouveau image of scenic composition featuring landscape. The composition should feel dramatic with moonlit scene. Use vibrant complementary colors throughout. Every detail should be intentional — from the foreground elements to the overall mood. The final result should look like a professional art nouveau piece.

Pro Tips

1Start with the default Quality (--q) value and make small adjustments to understand how it affects your specific prompt style.
2Different styles respond differently to Quality (--q) changes — what works for photorealistic may not work for anime or abstract.
3Keep notes on which Quality (--q) values work best for your favorite prompt structures — this builds your personal GPT Image knowledge base.
4When sharing prompts, always include your Quality (--q) setting — it can dramatically change results even with identical prompt text.
5For batch generation, lock your Quality (--q) value to maintain consistency across an entire set of related images.

Common Mistakes

✕Using extreme Quality (--q) values without understanding the trade-offs — moderate values usually produce the most balanced results.

✕Assuming the same Quality (--q) value works for all styles — always test with your specific prompt before committing to a batch.

✕Changing Quality (--q) and other settings simultaneously — adjust one parameter at a time to understand each one's effect.
