About GPT Image 1.5
GPT Image 1.5 is OpenAI's image generation model, best known for actually understanding what you meant. Long, specific, multi-clause prompts that confuse other models — “a three-panel comic where…”, “an infographic comparing…” — are where it shines, thanks to the language understanding it inherits from the GPT family.
On Avyn AI, GPT Image 1.5 comes in two quality tiers: Medium for affordable everyday work, and High for maximum fidelity when the render matters. It also supports image input for prompt-based editing with the same instruction-following strength.
Its aspect ratio options are focused — square, landscape 3:2, portrait 2:3 — which covers most real-world formats. Reach for it when your prompt reads like a brief rather than a keyword list, or when the image needs to contain structured elements like labels, panels, or diagrams.
Understands complex briefs
Multi-clause, structured prompts land reliably — comics, infographics, labeled diagrams, and scenes with specific spatial relationships.
Two quality tiers
Medium tier for affordable iteration, High tier for final-quality renders — pick per generation.
Instruction-faithful editing
With image input, it follows edit instructions precisely — useful when the change is specific and the wording is long.
What GPT Image 1.5 is best at
Images with structure: infographics, comics, diagrams, labeled scenes.
Prompts written as detailed creative briefs.
Editing tasks with long, specific instructions.
Illustrations that must respect spatial relationships between elements.
Concept visuals where getting the idea right beats raw resolution.
Prompt tips for GPT Image 1.5
Write full sentences and don't hold back on detail — this model rewards brief-style prompts over keyword lists.
Spell out spatial relationships: “the chart on the left, the mascot pointing at it from the right.”
Use Medium tier while shaping the idea; switch to High only for the final render — the quality gap is real but so is the price gap.
