You'll find the model selector across tools, including the Editorial tool, Upload & Edit, and Create from Scratch. The model you pick affects three things: how closely your prompt is followed, the quality of the output, and how many credits you spend. ![Image Generation Models](https://storage.crisp.chat/users/helpdesk/website/-/c/8/b/f/c8bf533b39f9b00/image_nusw1w.png =600x294) ###### At a glance | | Fast | Pro | Max | | ---- | ---- | ---- | ---- | | Speed | Fastest | Moderate | Slowest | | Quality & detail | Good | Better | Best | | Prompt adherence | Basic | Strong | Strongest | | Credit cost | Lowest | Mid-range | Highest | | Resolutions | 1K, 2K, 4K | 1K, 2K, 4K | 1K, 2K | | Free at 1K | Starter, Pro, Enterprise | Pro, Enterprise | NA | | NSFW filter | Lower | Lower | Higher | | Best for | Brainstorming, light edits | Everyday production | Detailed prints, fabrics, long prompts | ### The models ###### Fast Our quickest and cheapest model, built for exploring ideas. Use it to brainstorm, test concepts and make lighter edits or generations. It follows prompts, but avoid it for very long or complex instructions. ###### Pro The balance between Fast and Max, in both speed and credits. It doesn't take long to generate, and it gives noticeably better quality and prompt adherence than Fast. Choose Pro when you need production-ready results without Max's cost or wait. ###### Max Our highest-quality and most expensive model. It takes longer to generate but delivers the sharpest detail, texture and clarity. Use it for: * Highly detailed prints, fabrics and garments * Long, detailed prompts that need precise adherence * Pulling elements from a reference or swapping items * Complex use cases Max has a stricter NSFW filter than Fast and Pro, and is only available at 1K and 2K. ###### Plans, free generations and credits Unlimited free generations apply **only at 1K resolution**. Any other resolution is charged, even on a model that is free at 1K. | Plan | Fast (1K) | Pro (1K) | Max (any) | | ---- | ---- | ---- | ---- | | Mini | Charged | Charged | Charged | | Starter | Free | Charged | Charged | | Pro | Free | Free | Charged | | Enterprise | Free | Free | Charged | * 2K and 4K are charged for every model, on every plan. * The credit cost for your selected model and resolution appears as a number on the Edit/Generate button before you run it.

Pro is free at 1K on Pro and Enterprise. Max is never free. On the Mini plan, every generation is charged. 2. **Why was I charged credits on a free model?** Free generations apply only at 1K. Selecting 2K or 4K on any model uses credits. 3. **How do I know what a generation will cost before I run it?** The credit cost appears as a number on the Edit/Generate button once you've picked a model and resolution. 4. **Why can't I select 4K with Max?** Max is available only at 1K and 2K. For 4K output, use Fast or Pro. 5. **Why is my Max generation taking longer?** Max is our slowest model because it produces the highest detail. Longer load times are expected. 6. **My lingerie or swimwear image was blocked. What should I do?** Max has a stricter NSFW filter. Switch to Fast or Pro, which have lower filters, for underwear, bikini and lingerie shoots. 7. **My long prompt isn't being followed. What should I change?** Switch to Max. It handles long, detailed prompts and reference-based swaps best. Fast is not recommended for complex prompts. 8. **Are these models the same across all tools?** Yes. Fast, Pro and Max are available for both generation and editing across tools, including the Editorial tool, Upload & Edit, and Create from Scratch. **Related Articles:** 💳 [Credits Usage](https://help.caimera.ai/en/article/credits-usage-1pshr4i/): Understand credit usage across Caimera’s image, video, and editing tools. 📋 [FAQs on Credits and Plans](https://help.caimera.ai/en/article/faqs-on-credits-and-plans-y3tjxf/): Find answers to common questions about credits, plans, limits, and billing. 🎨 [How to use Editorial Templates on Caimera](https://help.caimera.ai/en/article/how-to-use-editorial-templates-on-caimera-1yz0fq/): Learn how to create and use Editorial Templates for your workflows. 📚 [Your Caimera Library: Manage Generations, References, Products & Brands](https://help.caimera.ai/en/article/your-caimera-library-manage-generations-references-products-brands-18t3y33/): Learn how to organize and manage your generations, references, products, and brands. 🤖 [Meet Caimera Agents](https://help.caimera.ai/en/article/meet-caimera-agents-bp8f56/): Explore Caimera’s AI Agents and how they can support different creative workflows.
