GPT Image 1.5

Introduction to GPT Image 1.5

GPT Image 1.5 is an AI image generation and editing model from OpenAI, released on December 16, 2025. It creates and edits images from natural-language prompts with precise control over content, lighting, materials, and layout. The model focuses on production-quality output and improved readability for in-image text.

It is designed for designers, marketers, product teams, educators, and developers who need to generate photorealistic visuals, UI mockups, infographics, and other commercial assets quickly. GPT Image 1.5 runs up to 4x faster than the prior generation and reduces per-image cost by approximately 20%. A commercial license is included, and a free trial (2 images, no credit card) is available via the web editor.

Key Takeaways

• Text-to-image generation for photorealistic images, logos, UI mockups, and infographics
• Precise, region-specific image editing without altering the entire image
• Improved text rendering for dense paragraphs, small fonts, and complex layouts
• Up to 4x faster processing than GPT Image 1; complex prompts complete in about 2 minutes
• Approximately 20% lower cost per image than previous models
• Commercial license included
• Accessible via a web editor and API; API calls benefit from the same speed improvements
• Ranked #1 on LMArena for text-to-image and image editing (as reported)

How GPT Image 1.5 Works

Users provide plain-language prompts to generate images. The model synthesizes scenes with natural lighting, accurate materials, and consistent composition. Its layout-aware text rendering supports posters, menus, infographics, and other text-heavy graphics with improved legibility.

For editing, users submit an existing image and specify the parts to modify (such as clothing, background, lighting, or object removal). GPT Image 1.5 applies targeted changes while preserving identity and the rest of the composition. This enables iterative refinement without starting from scratch.

Access is available through a browser-based editor for interactive exploration and via API for automated workflows. The faster inference speeds reduce iteration time for both manual and programmatic use.

Core Benefits and Applications

• Marketing and advertising: campaign visuals, product hero images, posters, and promotional materials
• Product and UX teams: UI screens, layout concepts, and design alternatives with readable in-image text
• Education and communications: infographics, diagrams, and instructional graphics with legible typography
• Content production: editorial illustrations, social media assets, and brand imagery
• Rapid iteration: faster experimentation cycles for creative direction and A/B concepts
• Cost control: lower per-image costs relative to previous models and a small free trial to evaluate quality
