# Lumiet — Complete Product Guide > Chat-based AI image generator with 4K output and accurate text rendering. No prompt engineering needed — describe what you want, refine through conversation, and download production-ready images. Four models in one chat: Nano Banana (fast drafts), Nano Banana 2 (pro-quality at flash speed), Nano Banana Pro (4K with text), and Flux Fast (ultra-low-cost). --- ## Product Overview Lumiet is a conversational AI image generation platform at [lumiet.net](https://lumiet.net). Designed for e-commerce sellers, content creators, marketers, and educators. Instead of crafting complex prompts, users describe their needs in plain language and iterate through multi-turn chat. The AI remembers context, supports reference image uploads, and outputs in up to 4K resolution with readable text — all included for commercial use. ### How It Works **Four-Step Workflow**: 1. **Describe**: Type what you need in plain language. "White background product shot of my coffee mug, morning light from the left." No special syntax required. 2. **Generate**: The AI returns an image in seconds. Choose the right model for your task — Nano Banana for quick drafts, Nano Banana 2 for fast 4K output, Nano Banana Pro for maximum precision. 3. **Refine**: Not quite right? Just say so. "Make the light warmer" or "Add a subtle shadow." The AI remembers the full conversation. 4. **Export**: Download in up to 4K resolution. Use for product listings, social media, print, or client deliverables — commercial use included. ### Key Differentiators - **Chat-native interface**: Multi-turn conversation with full session history, no single-turn prompt limits - **4K resolution**: Nano Banana Pro outputs at 3840x2160, sharp enough for large-format printing and product packaging - **Accurate text rendering**: Logos, headlines, multilingual labels render clean in generated images — no more garbled letters - **Four models in one chat**: Switch between speed, quality, and cost per task without leaving the session - **Reference image editing**: Upload existing photos (up to 8 with Pro model) and modify through conversation — swap backgrounds, adjust lighting, change styling - **Character consistency**: Keep faces and styles consistent across scenes for brand mascots and recurring characters - **Credit-based pricing**: Pay per image, not flat subscription — start free with 10 credits, no card required --- ## AI Models Lumiet offers four AI models, each optimized for different use cases: ### Nano Banana - **Speed**: 2-5 seconds - **Resolution**: 1K (1024x1024) - **Cost**: 5 credits per image - **Best for**: Fast drafts, exploration, quick iterations - **Key features**: Quick turnaround, good for testing concepts and exploring ideas ### Nano Banana 2 - **Speed**: 4-6 seconds - **Resolution**: 1K to 4K - **Cost**: 7-14 credits (varies by resolution) - **Best for**: Pro-quality images at flash speed, when you need 4K but don't require deep reasoning - **Key features**: Bridges speed and quality — professional output without the Pro model's reasoning stage.

You type what you want — "a product photo of my coffee mug on a marble countertop with morning light" — and the AI generates it. If the lighting is off, you say "make the light warmer." If you want to try a different surface, say "switch to dark wood." Every message builds on the previous context, so the AI remembers your preferences throughout the session. You can also upload reference images directly in the chat. **Q: What's the difference between Nano Banana, Nano Banana 2, and Nano Banana Pro?** A: Nano Banana is optimized for speed and cost — it generates 1K images in 2-5 seconds at 5 credits each. Nano Banana 2 bridges the gap: pro-quality images at flash speed (4-6 seconds), with 1K-4K resolution support and 7-14 credits per image. Nano Banana Pro adds a deep reasoning stage for maximum precision — it reasons about composition and lighting before generating, supports up to 4K resolution (3840x2160), and handles complex text rendering. Use Nano Banana for quick exploration, Nano Banana 2 for fast high-quality output, and Nano Banana Pro for final deliverables requiring maximum detail. **Q: How much does it cost?** A: Lumiet uses a credit-based system. Nano Banana costs 5 credits per image, Nano Banana 2 costs 7-14 credits depending on resolution, Nano Banana Pro costs 10-20 credits depending on resolution, and Flux Fast costs just 1 credit. New accounts receive 10 free credits to get started — no credit card required. Paid plans start at $9.9/month for 500 credits. **Q: Can I use generated images for commercial purposes?** A: Yes. All images generated through Lumiet are allowed for commercial use per the underlying model provider terms. You can use them for product listings, marketing materials, social media posts, client deliverables, and printed materials. Generated images include an invisible digital watermark (SynthID) for AI provenance tracking — it does not affect commercial use in any way. ### Features **Q: Is Lumiet good for e-commerce product photos?** A: Nano Banana Pro is specifically strong for e-commerce. You can generate white-background product shots that meet Amazon and Shopify standards, create lifestyle scene photography by describing the environment around your product, and output in 1:1, 4:5, or 16:9 ratios to cover every platform requirement. Upload your raw product photo and iterate on backgrounds and lighting through chat. **Q: Can I upload reference images for editing?** A: Yes. Nano Banana supports up to 4 reference images per generation, and Nano Banana Pro supports up to 8. You can upload product photos for background replacement, style references for consistent branding, or existing designs for iterative editing. Just drop images into the chat and describe what you want changed — the AI preserves what you do not mention. **Q: What resolution does Nano Banana Pro support?** A: Nano Banana Pro supports three resolution tiers: 1K (1024x1024), 2K (2048x2048), and 4K (3840x2160). Higher resolutions use more credits — 10 credits for 1K/2K and 20 credits for 4K. The 4K output is sharp enough for large-format printing, product packaging, and high-resolution displays. **Q: How is Lumiet different from using Nano Banana in Gemini?** A: Using Nano Banana directly in Gemini gives you single-turn image generation. Lumiet adds multi-turn conversation with full session history and multiple model switching (Nano Banana, Nano Banana 2, Nano Banana Pro, Flux Fast) in one chat. You also get 7 aspect ratio presets optimized for different platforms and a credit-based pricing model more flexible than a flat subscription. Think of it as a specialized studio built around the Nano Banana engine. ### Technical **Q: What AI models are available?** A: Lumiet currently offers four models: Nano Banana (fast drafts, 2-5s, 1K), Nano Banana 2 (pro-quality at flash speed, 4-6s, up to 4K), Nano Banana Pro (maximum precision, up to 4K, text rendering, deep reasoning), and Flux Fast (ultra-low-cost at 1 credit per image). Additional models and video generation are being evaluated. **Q: What is Nano Banana?** A: Nano Banana is Google's image generation model built into the Gemini family. The latest addition, Nano Banana 2, delivers pro-quality images at flash speed — generating 4K results in just 4-6 seconds. Lumiet wraps the Nano Banana family in a chat-based interface so you can describe what you want, see the result, and refine it through conversation — no prompt engineering required. --- ## Changelog Dedicated changelog page: [lumiet.net/changelog](https://lumiet.net/changelog) Track every update to Lumiet.
