GPT Image 1.5 Pure Vision.
4x Faster.
OpenAI's image model for production-quality creation and precise editing.
Built for the speed of thought.
Prompt
“Professional fashion portrait in a rain-slicked Tokyo street, neon reflections, 35mm film grain, 4K”
GPT Image 1.5 is OpenAI's image generation and editing model, released on 16 December 2025, that creates photorealistic images with legible text and edits only what you ask while keeping faces, lighting and composition. OpenAI says it generates images up to 4x faster than its previous image model. On Segmind it runs through one API key with pay-as-you-go, per-token pricing.
The Architecture of Precision
Built for Professional Creation.
Three capabilities. Zero compromises.
Region-Aware Precision.
Change only what you specify. OpenAI built GPT Image 1.5 to alter only what you request while preserving lighting, composition and the appearance of people, so the background and lighting stay put while the selected region changes.
Prompt: “Change the leather strap to navy blue alligator skin, maintain all reflections.”
Text, Rendered Right.
Text is not decoration; it is data. GPT Image 1.5 renders crisp headlines, accurate price tables and legible body copy, so menus, signage and UI screens come out readable. The infographic revolution starts here.

How It Works
Thinks. Locks. Renders.
Intelligence at every layer.
4× Faster. Not 4% Faster.
Speed at every quality level.
OpenAI says GPT Image 1.5 generates images up to 4x faster than its previous image model. On Segmind, a high-quality image takes about 32 seconds on average, and the low and medium quality settings return drafts sooner.
A creative team can now explore significantly more iterations per session than with GPT Image 1.0. The economics of brainstorming change completely.
Draft Fast. Finish in Detail.
Quality settings.
GPT Image 1.5 has low, medium and high quality settings, so you trade detail for speed per request: low for fast concept drafts, medium for iteration, high for final assets. OpenAI built it for complex structured visuals such as infographics, diagrams and multi-panel layouts.
OpenAI cites strong real-world knowledge and reasoning, which helps GPT Image 1.5 depict objects, environments and lighting accurately.
Change Only What You Ask.
Less AI drift.
Older image models often redraw the whole image when you ask for one change, shifting faces, backgrounds and lighting. OpenAI built GPT Image 1.5 to alter only what you request while preserving lighting, composition and the appearance of people, so edits stay consistent round after round.
For brands, "close enough" is failure. Edits that keep everything else in place are what professional photography and branding need.

The specs behind the results.
Photorealism
Natural lighting, accurate materials and rich color. OpenAI lists high-fidelity photorealism first among the capabilities of GPT Image 1.5.
Identity Preservation
OpenAI built GPT Image 1.5 for robust facial and identity preservation across edits, character sets and multi-step workflows, so a campaign can keep the same person from frame to frame.
Structured Visuals
Reliable text plus complex layouts: infographics, diagrams and multi-panel compositions that need every label in the right place.
Technical Specifications
Why it matters
Text you can read, faces that stay the same and edits that leave the rest alone are what turn a generated image into a usable campaign asset.

The 4× Efficiency Compound
OpenAI says GPT Image 1.5 generates images up to 4× faster than its previous image model. That is not just faster images; it is a shift in creative staffing. A single art director can explore several creative directions in the time one used to take, and the cost of exploring a bad idea drops.

Frequently asked questions
What is GPT Image 1.5?
GPT Image 1.5 is OpenAI's image generation model, released on 16 December 2025. It creates photorealistic images with legible text from a prompt, and edits existing images while keeping faces, lighting and composition. Segmind serves GPT Image 1.5 and GPT Image 1.5 Edit through a pay-as-you-go API.
What makes GPT Image 1.5 different from GPT Image 1?
GPT Image 1.5 is faster and more precise than GPT Image 1. OpenAI says it generates images up to 4x faster, follows instructions more closely, renders text more reliably, and changes only what you ask for during edits while preserving lighting, composition and the appearance of people.
How does GPT Image 1.5 handle image edits?
GPT Image 1.5 changes only what you request. OpenAI built it to preserve lighting, composition and the appearance of people across edits. On Segmind, send one or more reference images and a prompt to GPT Image 1.5 Edit, and add an optional mask to limit the change to one region.
Can GPT Image 1.5 render text inside images?
Yes. GPT Image 1.5 renders crisp, legible text inside images, and OpenAI lists reliable text rendering among its key capabilities. It suits menus, product labels, signage, UI mockups and infographics. Spell out the exact wording and where it goes in your prompt.
How much does GPT Image 1.5 cost on Segmind?
GPT Image 1.5 costs $10 per million input tokens and $40 per million output tokens on Segmind, as of 13 October 2026. A high-quality image, the default, has averaged about $0.17 over the last 30 days. Lower quality settings produce fewer output tokens and cost less.
What image sizes and formats does GPT Image 1.5 support?
GPT Image 1.5 outputs 1024x1024, 1536x1024 (landscape) or 1024x1536 (portrait) images, or picks a size automatically. It returns PNG, JPEG or WebP with adjustable compression, and can generate transparent backgrounds for overlays and product cut-outs.
What quality settings does GPT Image 1.5 have?
GPT Image 1.5 has low, medium, high and auto quality settings. Low is fastest and suits drafts and high-volume work, medium balances speed and detail, and high gives the richest detail for final assets. Segmind uses high by default.
How do I use the GPT Image 1.5 API?
Create a Segmind API key, then send a POST request to https://api.segmind.cyou/v1/gpt-image-1.5 with your prompt and the x-api-key header. GPT Image 1.5 returns the image in the response. For edits, call https://api.segmind.cyou/v1/gpt-image-1.5-edit with image_urls and a prompt.
How does GPT Image 1.5 compare to Nano Banana 2?
GPT Image 1.5 is built for precise edits that keep faces, lighting and composition, and for reliable text, at up to 1536x1024. Nano Banana 2, from Google, adds optional real-time web search grounding and output up to 4K. Both run on Segmind with one API key, so you can compare them on the same prompt.
