GPT Image 1.5 Tips
- • GPT Image 1.5 excels at text rendering — specify exact text, font, and placement
- • Structure prompts as: background → subject → details → constraints
- • Camera terms (lens, aperture) steer realism better than "8K" or "ultra-detailed"
- • For tricky brand names, spell them letter-by-letter for accuracy
How to Use the Prompt Generator
Describe Your Vision
Select a use case category, set your quality level and intended use, then describe your subject in detail. GPT Image 1.5 works best when you structure information as background → subject → details → constraints.
Generate Your Prompt
Click "Generate" and our AI will craft an optimized prompt following GPT Image 1.5's official best practices, including proper structure, materiality, and camera terms that steer realism better than generic quality tags.
Copy & Create
Copy your prompt and paste it into ChatGPT, the OpenAI API, or any platform supporting GPT Image 1.5. Regenerate for variations or tweak your inputs and try again.
Frequently Asked Questions
What is GPT Image 1.5?
GPT Image 1.5 is OpenAI's latest image generation model, integrated into ChatGPT and available via the API. It delivers major improvements in photorealism, text rendering accuracy, style control, and structured visual generation (infographics, diagrams, UI mockups) compared to DALL-E 3.
How does this prompt generator work?
You fill in structured inputs like subject, art style, composition, and intended use. Our AI combines these with GPT Image 1.5 best practices from the official OpenAI cookbook — using structured ordering (background → subject → details → constraints) — to produce an optimized prompt.
What makes GPT Image 1.5 different from DALL-E 3?
GPT Image 1.5 offers dramatically better photorealism, accurate text rendering in images, identity preservation for edits, complex structured visuals (infographics, multi-panel layouts), and precise style transfer. It also supports quality-latency tradeoffs for different use cases.
Is this tool free to use?
Yes! You get 3 free prompt generations per day with no signup required. For unlimited access, sign up for a Promptslove membership which includes all AI tools and 20,000+ premium prompts.
Where can I use the generated prompts?
The prompts are optimized for GPT Image 1.5 via ChatGPT or the OpenAI API. They also produce excellent results with other advanced models like Midjourney, FLUX.1, and Stable Diffusion.
What is the Quality Setting for?
GPT Image 1.5 supports quality-latency tradeoffs. "Low" generates faster with simpler compositions, "Medium" balances speed and detail, and "High" produces maximum fidelity with the richest detail — ideal for professional work.
Can GPT Image 1.5 render text in images?
Yes, text rendering is one of GPT Image 1.5's strongest capabilities. Put your desired text in quotes or ALL CAPS, specify font style, size, color, and placement. For brand names, spell them letter-by-letter for best accuracy.
How many prompts can I generate for free?
You get 3 free prompt generations every 24 hours. This resets automatically. For unlimited generations, consider signing up for a Promptslove membership.
