What AI image models does Ketchup AI support?

Ketchup AI integrates the latest top AI image models in one platform with one subscription. The current lineup includes Nano Banana 2 (Google's newest flagship, recommended for all-around use), GPT Image 2 (OpenAI's specialist for text rendering and infographics), Nano Banana Pro (premium-tier with built-in search and reasoning), Flux (photorealistic specialist with 1-4 step Schnell mode), and the original Nano Banana (cost-effective baseline). New flagship models are typically integrated within hours of release — you don't have to wait, manage multiple API keys, or pay separate subscriptions for each model.

What is AI text-to-image and AI image-to-image?

Text-to-image generates a brand new image from a written prompt — describe what you want and the AI creates it from scratch. Use this for concept art, illustrations, marketing visuals, or anything that doesn't exist yet. Image-to-image takes a reference photo you upload and modifies it according to your instructions: change the style (photo → anime), restore damaged photos, colorize black-and-white pictures, swap backgrounds, edit specific details, or generate consistent character variations. Both modes work with all 5 models on Ketchup AI, and you can switch between them with one click — no separate tool needed.

How much does it cost to generate an AI image on Ketchup AI?

Generation cost varies by model and image specifications. Lighter models like the original Nano Banana cost just a few credits per image, while flagship models such as Nano Banana 2 and GPT Image 2 cost more for higher quality and 4K resolution. Image-to-image typically costs slightly more than text-to-image due to the additional analysis step. New users receive 10 free credits at signup to try the platform. For ongoing usage, you can either subscribe to a monthly plan (Basic, Pro, Max) or buy credit packs as you go — see the pricing page for the current rate card and per-model credit costs.

What resolutions and aspect ratios does Ketchup AI support?

Ketchup AI supports a full range of resolutions from standard 1024×1024 up to native 4K ultra-HD, depending on the model. Available aspect ratios cover every major use case: 1:1 (square — Instagram posts, profile pictures, album covers), 16:9 (landscape — YouTube thumbnails, banner ads, blog headers), 9:16 (portrait — TikTok, Instagram Stories, Reels), 4:3 and 3:4 (classic photography and book layouts), and 21:9 (cinematic widescreen). Nano Banana Pro and Nano Banana 2 deliver the highest 4K output, suitable for print, billboards, and high-fidelity displays. All resolutions download as PNG or JPG without watermark.

How long does AI image generation take?

Generation time depends on the chosen model and image complexity. Flux Schnell completes in 1-4 seconds (fastest mode for quick drafts). Nano Banana 2 standard text-to-image typically takes 3-8 seconds. GPT Image 2 with complex text rendering takes 8-15 seconds. Nano Banana Pro in 4K mode can take 15-30 seconds for the highest quality. Image-to-image edits add 2-5 seconds for upload and analysis. To speed things up: use shorter prompts when iterating, choose lower resolution for drafts and upgrade for final renders, and avoid running multiple heavy jobs simultaneously on lower-tier plans.

How to write better prompts for AI image generation?

A great prompt has 5 layers: (1) Subject — what or who is in the image (a young woman, a vintage car, a misty forest); (2) Style — photorealistic, oil painting, anime, isometric 3D, watercolor; (3) Composition — close-up, wide shot, top-down view, rule of thirds, symmetric framing; (4) Lighting — soft daylight, golden hour, neon glow, studio softbox, dramatic side lighting; (5) Details — color palette, textures, mood, time period, camera lens (e.g., 85mm portrait). Combine all 5 layers for the best results. Nano Banana 2 understands ambiguous and multilingual prompts, so you can write in your native language — Chinese, Japanese, Korean, Arabic, Spanish, and 7 other languages all supported natively without translation.

Can I use Ketchup AI AI images for commercial work?

Yes, with full commercial rights. Every image you generate on Ketchup AI is yours to use commercially worldwide — for advertising campaigns, ecommerce listings (Shopify, Amazon, Etsy), books and magazines, online courses, NFTs, client deliverables, merchandise, product packaging, app and game assets, and brand identity. There are no extra licensing fees, no royalty payments owed to Ketchup AI, and no attribution requirements (though we appreciate it when you mention us). The output is royalty-free in every country. The only restrictions are general legal ones: don't generate content that infringes existing trademarks, defames real people, violates publicity rights, or breaks local laws.

Why does AI image generation sometimes fail?

Failures are uncommon but can occur for several reasons: (1) Prohibited content — prompts asking for explicit, violent, or copyrighted celebrity content are blocked by safety filters; (2) Heavy load — during peak hours (especially after a new model launch), wait times may extend or jobs queue; (3) Network issues — slow or unstable internet can timeout uploads, especially for image-to-image with large files; (4) Vague prompts — extremely short prompts (1-2 words) sometimes don't give the model enough to work with; (5) File issues — for image-to-image, uploads must be JPG, PNG, or WebP under 10MB and at least 256×256. To resolve: shorten or rewrite the prompt, switch to a different model, retry after 30 seconds, or check your upload format and size.

How does Ketchup AI compare to Midjourney, DALL·E, or Adobe Firefly?

Ketchup AI is the only platform that aggregates 5+ flagship models — Nano Banana 2, GPT Image 2, Nano Banana Pro, Flux, and the original Nano Banana — under one subscription with one-click switching. Midjourney runs a single proprietary model primarily on Discord (web app exists but with limits). DALL·E is integrated into ChatGPT only and offers a single model. Adobe Firefly uses one Adobe-trained model, optimized for the Photoshop ecosystem. Ketchup AI wins on model variety, multilingual prompts (12 languages native vs English-best for others), and the ability to compare outputs across multiple flagship models with the same prompt. For the full breakdown, see our comparison table above.

Does Ketchup AI work on mobile devices?

Yes — Ketchup AI is fully responsive and runs on any modern mobile browser, including iOS Safari, Android Chrome, Samsung Internet, and Firefox Mobile. You can generate, preview, save to your phone gallery, and download AI images at full 4K resolution directly from your phone. Image-to-image works with photos taken on your device camera or selected from the photo library. There is no separate app to install — just open ketchup-ai.com and sign in. The mobile interface uses the same generator as desktop, with a touch-optimized layout for smaller screens, swipe gestures for the gallery, and one-tap save to camera roll.

What's the best AI model for text rendering in images?

GPT Image 2 is the top choice for any image where readable text matters — posters with headlines, infographics with labels, comics with speech bubbles, UI mockups with button text, product packaging with brand names, or educational diagrams. OpenAI's model has industry-leading typography accuracy, especially for English. For Chinese, Japanese, Korean, and Arabic text rendering, Nano Banana 2 and Nano Banana Pro are equally strong with native multilingual support. Pro tip: for best results, put the exact text you want in quotes inside your prompt — e.g., 'Generate a poster with the title "Summer Sale 2026" in bold sans-serif typography'.

What's the difference between Nano Banana 2 and Nano Banana Pro?

Both are Google's flagship image models on Ketchup AI, but they target different needs. Nano Banana 2 is the newest generation, optimized for all-around use — best prompt understanding, fastest iteration, and the default recommendation for most projects. Nano Banana Pro is the premium tier with built-in search and reasoning, deeper style transfer, and brand-consistent generation across multiple images — best for ad campaigns, client work, and design teams that need maximum fidelity and consistency. Pricing differs (Pro costs more credits per image). Quick rule: start with Nano Banana 2 for any new project; escalate to Pro when you need maximum quality, brand consistency, or interpretation of complex creative briefs.

How to fix distorted hands or faces in AI portraits?

Older AI models often produced extra fingers or distorted faces, but modern flagship models on Ketchup AI have largely solved this. Tip 1: use Nano Banana 2 or Nano Banana Pro — both are trained with state-of-the-art human anatomy datasets and produce correct hand and finger counts in 95%+ of generations. Tip 2: be specific in prompts ('hands clasped together', 'holding a coffee cup with five fingers visible'). Tip 3: for group photos, mention the exact number of people. Tip 4: if you still get a flawed result, switch to image-to-image mode and regenerate just the affected region. Tip 5: avoid older or experimental models for portrait-heavy work — see the model comparison above for which models excel at human anatomy.

Can I generate AI images of real people or celebrities?

For safety and legal compliance, Ketchup AI blocks generation of recognizable real public figures, celebrities, and politicians by name. You also cannot use uploaded photos of real people without their consent. This protects both you and the subjects from legal liability around publicity rights, defamation, and deepfake risks. What you CAN do: generate fictional people based on descriptive prompts ('a young Asian woman with curly hair, wearing a yellow raincoat'), use your own portrait photos for image-to-image edits, or generate stylized characters that don't represent any specific real person. For licensed commercial use of celebrity likenesses, you'll need to contact the rights holders directly — Ketchup AI cannot grant such rights.

Is there a free plan for Ketchup AI AI image generation?

New users receive 10 free credits at signup — enough to generate roughly 2-5 AI images depending on the model and resolution chosen. This lets you try Nano Banana 2, GPT Image 2, and other flagship models without payment, no credit card required. After the free credits, you can either subscribe to a monthly plan (Basic, Pro, Max) or purchase credit packs as you go. There is no time-limited trial — the free credits don't expire as long as your account stays active. All output (free or paid) includes full commercial rights and supports up to 4K resolution, with no watermark on any plan and no usage caps beyond your credit balance.

What's the best AI model for photorealism, anime, or product photos?

Different creative needs call for different flagship models. For photorealism (lifestyle photos, product shots, architectural visualization): use Flux — its photorealistic rendering is industry-leading. For anime and stylized illustration: use Nano Banana 2 — it handles cartoon, manga, and concept-art prompts beautifully with consistent character design. For product photography that needs text (ecommerce hero images with logos or labels): combine GPT Image 2 for typography accuracy with Nano Banana Pro for premium image quality. For mixed scenes with people and objects: Nano Banana 2 is the safest all-around choice. The Model Comparison section above breaks down each model's strengths and limitations in detail.
