Text Accuracy: Character-exact accuracy of rendered text against the required strings, transcription-checked. - Color Accuracy: CIEDE2000 distance between the hex values the prompt requires and the colors actually rendered. - Transparency: Whether the returned file carries a genuine alpha channel with clean edges, not a painted white or checkerboard background. - Resolution: Native output size of the returned file, measured per run. - Prompt Adherence: How faithfully the image satisfies the prompt checklist: objects, counts, positions and constraints. - Composition: Layout quality for design use: negative space, overlay-safe areas and compositional control. ## Model profiles - [GPT Image 1.5](https://img.ly/ai-benchmarks/models/gpt-image-1-5.md): OpenAI's GPT Image 1.5: strong instruction following and text rendering from the GPT-image line, at a mid-premium price. - [GPT Image 2](https://img.ly/ai-benchmarks/models/gpt-image-2.md): OpenAI's GPT Image 2: the successor to GPT Image 1.5, run here at the high quality tier. ## Frequently asked questions **Is GPT Image 1.5 or GPT Image 2 better for design work?** Neither wins every category. This page runs the models on identical prompts and marks each row’s winner in the head-to-head table, so the right choice depends on the criteria your product needs: cost, text accuracy, transparency, brand color and so on. **Which is cheaper to run, GPT Image 1.5 or GPT Image 2?** The head-to-head table lists the measured cost per image for each model and marks the lower-cost one on the Cost row; latency is shown the same way. Verify against the provider before committing volume. **How is the winner of each row decided?** The green check marks the best value in each row: highest score for quality criteria, lowest for cost and latency. When every model scores zero on a row (transparency, for most of the field) no winner is marked, because least-bad is not best. **How are the benchmark scores calculated?** Each image is scored 0 to 5 per criterion. Measured criteria (resolution, latency, cost, transparency, color accuracy) are computed automatically; quality criteria (text accuracy, prompt adherence, composition) are judged by an automated Claude vision tier against each prompt’s checklist. A model’s score in any scope averages its runs per criterion first, then gives each criterion one equal vote, so a criterion measured on every prompt cannot outweigh one measured on a few. Blind expert-panel review has not run yet; the dataset is pilot-0. **Can I use both GPT Image 1.5 and GPT Image 2 in one product?** Yes. You can route generation to either model per job and refine the output in an editable canvas. The IMG.LY AI Editor pairs any model’s generation with background removal, brand kits and editable text, so your users take whichever model’s result to production quality. --- ## More Resources - **[IMG.LY Website](https://img.ly/index.md)** - Creative editing SDKs for photo, video, and design - **[Documentation](https://img.ly/docs/cesdk/)** - CE.SDK developer documentation - **[Contact Sales](https://img.ly/forms/contact-sales.md)** - Get a custom quote.
