GPT Image 1.5 is OpenAI's image model on the GPT-image line, historically strong at instruction following. The full run makes it the outright quality leader at 4.51, and it is the only model in the suite that reliably emits a real alpha channel: it scored a perfect 5 on sticker and isolated-object transparency while the field averaged near zero. It also owns structured, text-bearing work, winning the bar chart and the labeled map outright. The price of all this is $0.12 per image and mid-pack latency, which sinks it on the cost-adjusted blend. The integration takeaway: route cut-out, chart and dense-text generations here and cheaper volume work elsewhere. It is the strongest single argument for multi-model routing in the whole dataset. ## Why it stands out - Highest quality mean in the suite: 4.51 of 5 across all quality criteria. - The only model that emits a real alpha channel: 5 of 5 on sticker and isolated-object transparency while the field averages near zero. - Owns structured, text-bearing work: won the bar-chart and labeled-map benchmarks outright. - The trade-off is $0.12 per image: reserve it for cut-outs, charts and dense text, and route volume work to cheaper generalists. - Provider: OpenAI - Tier: extended - Benchmarked endpoint: fal:fal-ai/gpt-image-1.5 - Available on the IMG.LY AI Gateway: no - Cost per image: $0.120 - p50 latency: 34.0s - Images benchmarked: 111 - Licensing: Commercial use via OpenAI API terms (served through fal). ## Scores by criterion (auto tier) - Transparency: 4.2 / 5 (9 scores across 9 runs) - Color Accuracy: 3.4 / 5 (9 scores across 9 runs) - Composition: 4.7 / 5 (9 scores across 9 runs) - Cost: 3.0 / 5 (111 scores across 111 runs) - Latency: 1.0 / 5 (111 scores across 111 runs) - Prompt Adherence: 4.6 / 5 (111 scores across 111 runs) - Resolution: 3.0 / 5 (111 scores across 111 runs) - Text Accuracy: 5.0 / 5 (24 scores across 24 runs) Blended overall (unweighted mean of all scored criteria): 3.07 / 5. Includes the interim Claude-VLM quality tier (prompt adherence, composition); not yet blind expert-panel reviewed. Because the blend is unweighted, cost and latency pull cheap, fast models above premium flagships. The use-case pages reweight the same measurements by job. ## Scores by category - Typography & Text Rendering: 3.4 / 5 - Logos, Icons & Vector-Style: 2.9 / 5 - Brand-Color Fidelity: 3.0 / 5 - Transparency & Cutouts: 3.0 / 5 - Composition & Negative Space: 3.3 / 5 - Spatial & Compositional Adherence: 3.0 / 5 - Human Subjects: Faces & Hands: 2.8 / 5 - Product & E-Commerce Staging: 3.0 / 5 - Consistency & Repeatability: 2.7 / 5 - Print Detail & Resolution: 3.0 / 5 - Style Adherence & Art Direction: 2.9 / 5 - Print-Production Graphics: 3.1 / 5 - UI & Design Mockups: 3.4 / 5 - Diagrams & Data Viz: 3.4 / 5 - Structured Spec Adherence: 3.0 / 5 ## Benchmarks featuring this model **Typography & Text Rendering** - [Wordmark](https://img.ly/ai-benchmarks/prompts/t04-wordmark.md) - [Poster Headline](https://img.ly/ai-benchmarks/prompts/t01-poster-headline.md) - [Product Label](https://img.ly/ai-benchmarks/prompts/t02-dense-label.md) - [CJK Neon Sign](https://img.ly/ai-benchmarks/prompts/t05-cjk-sign.md) **Logos, Icons & Vector-Style** - [Mascot Logo](https://img.ly/ai-benchmarks/prompts/l02-mascot.md) - [Icon Set](https://img.ly/ai-benchmarks/prompts/l01-icon-set.md) - [Monochrome Emblem](https://img.ly/ai-benchmarks/prompts/l03-emblem.md) **Brand-Color Fidelity** - [Two-Color Illustration](https://img.ly/ai-benchmarks/prompts/b01-two-color.md) - [Duotone Portrait](https://img.ly/ai-benchmarks/prompts/b03-duotone.md) - [ColorChecker Chart](https://img.ly/ai-benchmarks/prompts/b04-colorchecker.md) - [Smooth Gradient](https://img.ly/ai-benchmarks/prompts/b05-gradient-banding.md) **Transparency & Cutouts** - [Die-Cut Sticker](https://img.ly/ai-benchmarks/prompts/c01-sticker.md) - [T-Shirt Graphic](https://img.ly/ai-benchmarks/prompts/c02-shirt-graphic.md) - [Isolated Cutout](https://img.ly/ai-benchmarks/prompts/c03-isolated-object.md) **Composition & Negative Space** - [Banner with Negative Space](https://img.ly/ai-benchmarks/prompts/n01-banner.md) - [Vertical Story Background](https://img.ly/ai-benchmarks/prompts/n02-story-bg.md) - [Centered Product Margin](https://img.ly/ai-benchmarks/prompts/n03-margin-product.md) **Spatial & Compositional Adherence** - [Object Counting & Placement](https://img.ly/ai-benchmarks/prompts/x01-objects.md) - [Scene Relations](https://img.ly/ai-benchmarks/prompts/x02-scene-relations.md) - [Negation: Clean Background](https://img.ly/ai-benchmarks/prompts/x03-negation.md) **Human Subjects: Faces & Hands** - [Hand Holding a Sphere](https://img.ly/ai-benchmarks/prompts/h03-sphere-grip.md) **Product & E-Commerce Staging** - [Cosmetics Hero](https://img.ly/ai-benchmarks/prompts/p01-cosmetics.md) - [Floating Sneaker](https://img.ly/ai-benchmarks/prompts/p02-sneaker.md) **Consistency & Repeatability** - [Character Series: Greenhouse](https://img.ly/ai-benchmarks/prompts/s01-character-greenhouse.md) - [Character Series: Desk](https://img.ly/ai-benchmarks/prompts/s02-character-desk.md) - [Character Series: Market](https://img.ly/ai-benchmarks/prompts/s03-character-market.md) **Print Detail & Resolution** - [Fine-Line Mandala](https://img.ly/ai-benchmarks/prompts/r01-mandala.md) - [Illustrated Map](https://img.ly/ai-benchmarks/prompts/r02-map.md) **Style Adherence & Art Direction** - [Mid-Century Travel Poster](https://img.ly/ai-benchmarks/prompts/a01-travel-poster.md) - [Isometric Office](https://img.ly/ai-benchmarks/prompts/a03-isometric.md) **Print-Production Graphics** - [Greeting Card](https://img.ly/ai-benchmarks/prompts/g01-greeting-card.md) - [Seamless Pattern Tile](https://img.ly/ai-benchmarks/prompts/g03-pattern-tile.md) - [Stationery Mockup](https://img.ly/ai-benchmarks/prompts/g04-stationery-mockup.md) - [Three-Panel Comic](https://img.ly/ai-benchmarks/prompts/g05-comic-strip.md) **UI & Design Mockups** - [E-Commerce Product Page](https://img.ly/ai-benchmarks/prompts/ui03-pdp.md) **Diagrams & Data Viz** - [Labeled Bar Chart](https://img.ly/ai-benchmarks/prompts/d01-bar-chart.md) **Structured Spec Adherence** - [Structured JSON Scene](https://img.ly/ai-benchmarks/prompts/j01-json-scene.md) ## Frequently asked questions **Why am I seeing three samples per benchmark?** Image generation is stochastic: the same prompt produces different images on every run, so a single sample measures luck, not ability. Every model runs each benchmark three times with fixed seeds (1111, 2222, 3333), or three unseeded samples where the API accepts no seed. Scores average all three samples, and the consistency benchmarks measure the variation itself. **Is GPT Image 1.5 good at typography & text rendering?** In this benchmark GPT Image 1.5 scores highest on Typography & Text Rendering. The per-category breakdown on this page shows where it is strong and weak, so use the category scores, not the blended overall, to judge it for a specific job. **How much does GPT Image 1.5 cost per image?** GPT Image 1.5 costs $0.120 per image at the endpoint and default parameters we benchmarked, shown in the stats above. Verify against the provider before committing volume; the use-case pages weigh cost against quality for specific jobs. **Can I use GPT Image 1.5 output in production without editing?** Not reliably. Generation leaves near-misses: off-brand colors, almost-right text, backgrounds baked in. The IMG.LY AI Editor lets your users refine GPT Image 1.5's output to production quality with background removal, brand kits and editable text on a real canvas. **How does GPT Image 1.5 compare to other models?** The model rankings place GPT Image 1.5 against every other model on the same prompts, and the comparison pages put it head to head with a specific rival. Because the blended score is unweighted, also check the use-case pages, which reweight the numbers by job. **Which use cases is GPT Image 1.5 best for?** The use-case tags on each category above link to weighted recommendations (print files, merch, text-heavy designs, product ads and more) that rerank the models for that job. A model that wins on price can lose on typography, so match GPT Image 1.5 to the use case that matters to you. --- ## 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.
