Today, OpenAI officially released GPT Image 1.5, further completing its visual model matrix. Unlike Google’s Nano Banana, which covers both image and video in a single sweep, OpenAI has adopted a “divide and conquer” strategy: while Sora 2 focuses on video and physical world simulation, the newly released GPT Image 1.5 fills the critical gap for high-precision static image generation and editing.
This update aims to differentiate itself from the competition by focusing squarely on generation quality and—crucially—controllable editing.
GPT Image 1.5: The Update Highlights
In their official release, OpenAI summarized the GPT Image 1.5 upgrades with four keywords: 精度 Editing, Speed, Text Clarity, and Cost-Efficiency.
The core logic of this update is clear: a shift from a “toy” to a “production tool.” It addresses the four major pain points that have historically hindered the commercial adoption of the DALL-E series:
Precision Editing
This is the headline feature. Previously, modifying an AI image often felt like the “butterfly effect”—change one small thing, and the whole image shifts. Now, GPT Image 1.5 supports Consistent In-Painting. This means you no longer need to regenerate from scratch because the AI misunderstood a prompt, nor do you need to export to Photoshop or Canva for manual patching.
OpenAI highlighted capabilities that allow users to fine-tune images via simple instructions while keeping the base image intact:
- Local Locking: Modify specific areas (e.g., changing a shirt color) without destroying the lighting, composition, or the subject’s likeness.
- Element Control: Add or remove items logically (e.g., “add a person to the left,” “remove the pedestrian in the background,” “put a coffee on the table”).
- Compositing: Combine people or objects from different source images into a single, cohesive scene.
- Style Transfer & Iteration: Maintain consistent artistic style across multiple rounds of “tweaking.”
テキストレンダリング
A common pain point of previous models was “AI gibberish”—blurry text or weird spelling. GPT Image 1.5 achieves a practical breakthrough here:
- Short Text 正確さ: Spelling accuracy for headlines, button copy, and brand names has improved drastically.
- Natural Typography: Fonts and layout blend naturally with the image style, making it ideal for promotional graphics and cover art.
- UI Friendly: Generates more logical text and layouts for complex UI mockups, app screenshots, and dashboards.
- (Note: While long paragraphs may still be imperfect, it is now commercially viable for marketing posters, social media assets, and thumbnails.)
A Quantum Leap in Speed
Thanks to new architecture, generation speed is 4x faster than the previous generation. This isn’t just about saving time; it changes the workflow:
- Batch Production: drastically reduced wait times for product showcases and ad creatives.
- High-Velocity A/B Testing: Rapidly generate and test multiple variants (copy, colors, composition) to make data-driven decisions.
- API Performance: For developers, higher QPS (Queries Per Second) means smoother integration into actual products without the “lag.”
More Accessible Pricing
The B2B market is the new battleground for large models. To stay competitive, OpenAI has lowered API costs for GPT Image 1.5 by 20%.
- Lower Unit Cost: Cheaper per generation and per edit.
- Higher ROI: Combined with faster speeds, large-scale commercial generation (e.g., marketing platforms, automated design tools) becomes significantly more economically viable.
Why is GPT image 1.5 considered a production tool? A comprehensive introduction is shown in the table below.
| Update Category | Key Features & Capabilities | Commercial Impact (Why It Matters) |
| Precision Editing | • Consistent In-Painting: Modify specific areas without the “butterfly effect.” • Local Locking: Change colors or details while keeping lighting/likeness intact. • Element Control: Logically add/remove objects (e.g., add coffee, remove pedestrians). • Compositing: Combine elements from different images seamlessly. | Eliminates the need to regenerate from scratch or export to Photoshop. Transforms the model into a reliable tool for fine-tuning assets. |
| Text Clarity | • Short Text Accuracy: Drastic improvement in spelling for headlines, buttons, and brand names. • Natural Typography: Fonts blend naturally with image styles. • UI Friendly: Logical layouts for app screenshots and dashboards. | Solves the “AI gibberish” problem. Makes the model commercially viable for marketing posters, social media assets, and thumbnails without heavy post-editing. |
| Speed & Performance | • 4x Faster Generation: A quantum leap in processing speed. • Higher QPS: Supports higher Queries Per Second for developers. | Enables high-velocity A/B testing (rapidly testing variants) and smoother API integration for real-time products. drastic reduction in wait times for batch production. |
| Cost-Efficiency | • 20% Lower API Costs: Cheaper pricing for both generation and editing. • Scalability: Optimized for the B2B market battleground. | Significantly increases ROI for large-scale commercial generation (e.g., automated design tools, marketing platforms), making the business case easier to justify. |
The Showdown: GPT Image 1.5 vs. Nano Banana
Design Arena released the performance figures for the visual models, with GPT image 1.5 surpassing the recently released Gemini 3 Pro image preview and ranking first. The hottest topic on social media right now is still the face-off between GPT Image 1.5 and Google’s ナノバナナ. Asking “who is stronger” is too one-dimensional. The better question is about trade-offs.
Here is a comprehensive breakdown:
Capability
- GPT Image 1.5 (The Editor): Its superpower is 精度 Editing. It’s not just a generator; it’s a retoucher. It allows for iterative local modifications while maintaining consistency. Combined with superior text rendering, it is the foundation for creating commercial assets (Posters, Banners).
- Nano Banana (The Explorer): 焦点を当てる Stylization and Artistry. It leans towards “one-shot generation.” While weaker in editing control, it often delivers serendipitous, surprising results with simple prompts. It offers more “playability” for general users.
Style & Aesthetics
- GPT Image 1.5: Retains the OpenAI “Artist” DNA. Images feel premium, with rigorous lighting logic and composition akin to Commercial Photography または CG Art. The look is clean, transparent, and high-end.
- Nano Banana: Takes the path of Hyper-Realism. Its texture feels like “straight out of a smartphone camera,” retaining real-world noise, imperfect textures, and a “lived-in” atmosphere. This imperfection makes it deceptively realistic for documentary-style content.
Performance & Logic
- スピード： While GPT is faster than before, ナノバナナ (optimized for lightweight usage) still wins on raw speed, making it ideal for real-time applications.
- Understanding: GPT Image 1.5 shows superior 理解 of long, complex prompts and logical relationships. However, for Prompt Adherence regarding specific pixel-level retention, Nano Banana has a loyal following.
Commercial Positioning
- GPT Image 1.5: A standardized, transparently priced Commercial API. The price drop + speed boost = high ROI for enterprise applications.
- Nano Banana: Currently more active in research and creative communities. Its commercial strategy is still evolving, often positioned as a tool for high-frequency creative experimentation.
