Each model has distinct strengths, supported quality levels, credit costs, and generation limits. Use this page as a reference when selecting a model for your image generation task. *** ### How to Read This Page | Column | What It Means | | ------------------------ | ------------------------------------------------------------------- | | **Credits / Image** | Credits consumed per generated image at the specified quality level | | **Quality** | Supported resolution or quality tiers for that model | | **Max Generations** | Maximum number of images producible in a single run | | **Max Reference Images** | Maximum number of reference images uploadable (image-to-image only) | {% hint style="info" %} Models marked with ⭐ are available on **paid plans only**. {% endhint %} *** ### Text-to-Image Models Text-to-image models generate images from written prompts. Select based on the visual style, quality level, and credit budget required for your task. #### **Flagship Models** | Model | Quality | Credits / Image | Max Generations | Best For | | --------------------- | ------- | --------------- | --------------- | ------------------------------------------------------------------------------------------ | | **Nano Banana 2** | 0.5K | 15 | 4 | General-purpose generation — fast, versatile, strong quality across a wide range of styles | | | 1K | 21 | | | | | 2K | 32 | | | | | 4K | 48 | | | | **Nano Banana Pro** ⭐ | 1K / 2K | 42 | 4 | Premium quality — higher fidelity for demanding, production-ready outputs | | | 4K | 75 | | | *** #### **OpenAI Models** GPT Image 2 uses quality tiers — **Low**, **Medium**, and **High** — instead of resolution values. These correspond to increasing levels of detail, prompt adherence, and visual fidelity: * **Low** — fast generation, basic detail, suitable for drafts and concept testing * **Medium** — balanced quality for most professional use cases * **High** — maximum detail, photorealism, and prompt accuracy for final production output | Model | Quality | Credits / Image | Max Generations | Best For | | ----------------- | ------- | --------------- | --------------- | ------------------------------------------------------------------------------- | | **GPT Image 2** ⭐ | Low | 4 | 8 | Photorealism, text-in-image, structured scenes with strong prompt comprehension | | | Medium | 19 | | | | | High | 69 | | | *** #### **Google Models** | Model | Quality | Credits / Image | Max Generations | Best For | | ---------------------- | ------- | --------------- | --------------- | ---------------------------------------------------------------------------------- | | **ImageGen 4** | 1K / 2K | 11 | 4 | General-purpose — Google's latest image model, strong all-rounder for varied tasks | | **ImageGen 4 Fast** | 1K / 2K | 6 | 4 | Fast generation — quick iterations, draft testing, high-volume workflows | | **ImageGen 4 Ultra** ⭐ | 1K / 2K | 16 | 4 | Maximum quality — highest fidelity tier from Google for production-ready output | *** #### **Flux Models** *Black Forest Labs* | Model | Quality | Credits / Image | Max Generations | Best For | | ---------------- | -------- | --------------- | --------------- | -------------------------------------------------------------------------------------------- | | **Flux.2 Pro** ⭐ | Standard | 19 | 4 | Creative, high-fidelity generation — next-generation Flux model for detailed artistic output | | **Flux.1 Dev** | Standard | 8 | 4 | Developer-friendly experimentation — open model, great for testing and creative exploration | *** #### **ByteDance Models** | Model | Quality | Credits / Image | Max Generations | Best For | | ---------------- | -------- | --------------- | --------------- | ---------------------------------------------------------------------------------------------------- | | **Seedream 4.5** | Standard | 13 | 6 | Creative and stylized images — ByteDance's flagship, exceptional for artistic and expressive outputs | *** #### **Recraft Models** | Model | Quality | Credits / Image | Max Generations | Best For | | -------------- | -------- | --------------- | --------------- | ----------------------------------------------------------------------------------------------------- | | **Recraft V4** | Standard | 13 | 4 | Design assets and icons — clean graphic design output, brand-consistent visuals, vector-style imagery | *** ### Image-to-Image Models Image-to-image models accept one or more reference images to guide generation. Everything else — prompt, keywords, output controls — works the same as text-to-image. The reference images influence composition, style, subject, or structure of the output. #### **Qolaba Flagship Models** | Model | Quality | Credits / Image | Max Generations | Max Reference Images | Best For | | --------------------- | ------- | --------------- | --------------- | -------------------- | -------------------------------------------------------------------------------------- | | **Nano Banana 2** | 0.5K | 15 | 4 | 13 | General-purpose reference-guided generation — versatile, consistent quality | | | 1K | 21 | | | | | | 2K | 32 | | | | | | 4K | 48 | | | | | **Nano Banana Pro** ⭐ | 1K / 2K | 42 | 4 | 13 | Premium reference-guided generation — highest fidelity for brand and production assets | | | 4K | 75 | | | | *** #### **OpenAI Models**
